Executive
Summary
This report represents Tri-Met’s 5-year plan for the deployment of Intelligent
Transportation System projects (ITS) from FY 2002 to FY 2006. Simply stated, ITS is the application of technology in
transportation systems. Integrating ITS in Tri-Met’s bus and rail systems offers the Portland region opportunities for
improvements to the transportation system through enhanced efficiency and safety. For Tri-Met and other transit systems, ITS projects can increase ridership and improve customer service through efficiencies such as better system on-time performance and reduced agency cost.
Tri-Met has developed this plan to ensure the Portland region is able to reap the benefits of ITS; thus, projects were chosen that support each other as well as regional integration, build on the agency’s existing infrastructure, and offer opportunities for future ITS expansion. This plan also addresses the federal rule for conformance with the National ITS Architecture and Standards under the Transportation Equity Act for the 21st Century (TEA-21). Additional background information can be found in the Overview section of this report. In addition, the Overview includes the goals and objectives of this plan and the benefits of ITS projects, as well as brief summaries of the regional architecture, project costs and a proposed schedule.
This plan includes regional projects as well as projects that are internal to Tri-Met. The agency has identified a set of ten internal ITS projects that build on the region’s ITS infrastructure. Detailed information on Tri-Met’s ITS projects can be found in Section 2.0 Tri-Met ITS Project
Descriptions. The Portland region also has begun to work toward deployment of operational ITS projects through TransPort, a regional partnership of both the public and private sectors. The current TransPort plan contains 15 regional ITS projects. Tri-Met has been a significant contributor on three of these projects. See the Regional ITS Project
Descriptions section for more detail on two
of these projects. The third regional project--OR0206 – Regional Intermodal Transit Traveler Information and Security System--closely parallels Tri-Met’s Transit Tracker project. This plan also includes three appendices. Appendix A provides a general introduction to concepts of the National ITS Architecture as well as a glossary of the definitions relevant to the Tri-Met 5-Year ITS Plan. Appendix B includes estimated capital costs for each project. Finally,
Appendix C lists the project managers
assigned to each project at the time of publication.
The twelve projects that are the subject of this plan are listed below with a brief description as well as total capital costs and major milestones.
Tri-Met Internal Projects
TM001 – Transit Tracker (Real Time Customer Information Displays) : This project will provide real time transit
information (e.g., vehicle arrival information or service disruption messages) to the
internet, 50 rail stations, and 250 bus stops. The total project cost is expected to be $3.5 million with the prototyping, evaluation and initial deployment completed in the next two years. Additional deployment of
approximately 50 locations will occur yearly.
TM002 – Transit Signal Priority: This project will extend the “green-time” at 250 traffic signals for all buses running behind schedule in Portland and, potentially,
throughout the region. The total project cost is estimated at $4.5 million ($1.5 million Tri-Met and $3 million City of Portland) with initial field installation and field-testing completed by next year.
TM003 – LIFT Scheduling System Upgrade/Electronic Data Transmission: This project will upgrade the LIFT
paratransit scheduling software to improve the interface with the bus dispatch system, upgrade the driver manifest system, and enhance the driver display and interface equipment. In the next year the PASS/BDS interface will be improved to eliminate retyping of manifest changes by LIFT operators. In the long term, all LIFT buses will be moved to Advanced Mobile Data Terminals (AMDTs) and the LIFT
scheduling system will be fully integrated with the BDS. The total project cost is estimated at $2.8 million.
TM004 – Automated Stop
Announcements: This project will provide the capability for audible messages on all of Tri-Met’s bus fleet. The automatic
announcement of stops will allow visually impaired passengers to identify their location, similar to the system in operation on the MAX light rail. Deployment of the Automated Stop Announcement equipment will follow new fleet procurements. Current fleet replacement schedule projections are approximately 75 a year in 2004 and 2005. Total project cost is estimated at $725,000. TM005 – Bus Dispatch System Upgrade: This project moves Tri-Met’s
computer-aided bus dispatch system toward
data model. In the next year the operating system will be upgraded and modern
workstations will be acquired. Over the next three years the system will be upgraded to OrbCad NT. The project will support use of current vehicle equipment (In-Vehicle Units or “IVUs”) as well as new vehicle
equipment (Advanced Mobile Data Terminals or “AMDTs”) built by Orbital TMS. Total project cost is estimated at $2.3 million.
TM006 – Scheduling System Software Procurement: This project will replace Tri-Met’s current software that is
responsible for run cutting and schedule blocking. The new system will provide stronger linkages between the scheduling system and other Tri-Met databases as well as an improved user interface and more powerful runcutting and blocking
algorithms. The system will be installed and tested in the next year. Total project cost is $900,000.
TM007 – Radio and Microwave Replacement Project: The Radio and Microwave Replacement project will involve the replacement of UHF fixed and mobile radio equipment and several microwave hops. In the next year, all transmitters and receivers at Tri-Met’s remote sites will be replaced. Digital microwave links will replace the current analog system except at the Mount Scott-Polivka and Justice Center sites. In concert with the BDS upgrade, the system will be upgraded to Motorola Gold in 2003. The existing UHF and 800 MHz mobile radio system configuration will be retained. Total project cost is $6.4 million.

functionality of both BDS and rail control software. This project will be completed using Tri-Met in-house staff. There are no capital costs associated with the project.
TM009 – Automated Yard Mapping and Vehicle Assignment Project: The
Automated yard mapping and vehicle assignment project will use the existing communication and bus dispatch system and transit vehicle Global Positioning System (GPS) to correctly locate all transit vehicles in the yard and assign them to blocks (trains). This project will be reviewed by Tri-Met’s Information Technology
Committee (ITC). If approved by the ITC, a bus assignment model will be developed in the next two years and the benefits of an automated fleet assignment process will be evaluated. Deployment of the system will begin in 2003. This project is funded through Tri-Met operating funds (software modifications).
TM010 – LIFT Program Integrated Voice Response: This project develops Integrated Voice Response (IVR) features that will give customers more positive control over how and when they request, reserve, receive confirmation, change or cancel LIFT trips, and will also provide additional options for customer notification regarding service. The upgrade of the LIFT scheduling software in 2005 will allow for the incremental
implementation of IVR features in following years. Total project cost is $200,000.
Regional Projects
OR0158 – Transit Buses as Traffic Probes: Using buses as traffic probes, Tri-Met will report travel speeds over key corridors determined to be of interest to the City of Portland and the Oregon Department of Transportation. This data will allow these agencies to better monitor and manage the transportation system. The development and deployment of the system will occur this year, depending on the regional allocation of Federal ITS grant funding. Total project cost is $250,000.
OR0204 – Regional ATIS Sustainable Business Model Deployment: The deployment of the regional advanced traveler information system would take distribution of transportation information to the next level, with information tailored specifically to the needs of individual travelers. The Tri-Met portion of this project would primarily entail the collection and distribution of real time operational data, as well as schedule and fare data. The development and deployment of the system will occur this year, depending on the regional allocation of Federal ITS grant funding. Total project cost is $200,000.

1.0 Overview
1.1 BACKGROUND
Tri-Met has a long history of using technology to improve bus, rail and paratransit service. While early projects involving technological advances were not referred to as Intelligent Transportation Systems (ITS) projects, they would be considered ITS projects if they were done today. Examples of these early projects include the radio and microwave system, which was installed in 1981 and expanded in 1983; the first automatic passenger counters which were installed in 1984; and traffic signal priority for MAX
trains in 1986. In the decade that followed, Tri-Met’s ITS program accelerated, with the installation of such important foundational systems as the computer-aided bus dispatch system (BDS) and rail control system (CCS). Currently, Tri-Met has identified ten ITS projects that build on this
base infrastructure. These projects, together with several regional ITS projects that contain transit elements, are the focus of this 5-Year ITS Plan update.
For many years the Portland metropolitan region has invested in multi-modal
transportation solutions to enhance mobility and maintain the region’s livability
standards and reputation. Tri-Met’s extensive state-of-the-art bus, rail and paratransit systems are representative of that commitment. More recently, the region has started to focus on Intelligent Transportation Systems (ITS) as a complementary means to enhance the efficiency and safety of travel. Examples of this focus are the freeway
management system implemented by the Oregon Department of Transportation (ODOT) and the advanced signal control software used by the City of Portland to control most of its traffic signals.
TransPort, a partnership that includes the States of Washington and Oregon,
metropolitan planning organizations Metro and Regional Transportation Council, the Port of Portland, transit operators Tri-Met and C-TRAN and academic and private sectors, have been working to continue progress on the incremental
conceptualization, planning, design, and deployment of operational ITS. In each of the last two years, the Portland region has received over half a million dollars in ITS earmark funds to develop regional ITS projects. A technical advisory committee (TransPort TAC) has
prioritized the application of these funds toward regional projects that integrate and leverage on the various projects that have been completed by the individual regional partners. Several of these projects include transit participation and are included in Section 3 of this plan. Tri-Met’s ongoing and planned ITS projects form the basis of this plan, which covers the time period from FY 2002 to FY 2006 (with FY 2000 serving as the base year). This update of Tri-Met’s 5-Year ITS Plan ensures ITS projects deployed by the agency are cost effective and timely. A key element of this plan is the identification of a system architecture for Tri-Met’s ITS projects. To best achieve cost efficiency and
interoperability goals, project The Portland metropolitan
region has been investing, for many years, in multi-modal
transportation solutions to enhance mobility and maintain the region’s livability standards and
inter-relationships and associated system interfaces and standards need to be evaluated and clearly defined during the project
planning stage. This plan addresses these needs.
Another benefit of completing system architecture documents is to address the federal rule for conformance with the National ITS Architecture and Standards. Section 5206(e) of the Transportation Equity Act for the 21st Century (TEA-21) requires that ITS projects using funds from the Highway Trust Fund (including the Mass Transit Account) conform to the National ITS Architecture and Standards. The federal rule requires that ITS projects that affect regional integration be evaluated for institutional and technical integration with transportation systems and
service within the region, as well as consistency with the applicable regional ITS architecture or the National ITS Architecture. To meet the federal rule ITS projects should:
• Engage a wide range of stakeholders (internal and external);
• Enable the appropriate electronic information sharing between stakeholders;
• Facilitate future ITS expansion; and
• Consider the use of applicable ITS standards.
1.2 WHAT IS ITS?
Intelligent Transportation Systems involve
safety, to provide services to travelers and to assist transportation service providers to implement suitable traffic management strategies. ITS focuses on increasing the efficiency of existing transportation resources, in order to improve the overall performance of the system. Improving the system is achieved by providing better management of transportation systems, and by providing services and information to travelers so they can make better travel decisions.
1.3 MISSION, GOALS AND OBJECTIVES
The projects presented in this report support Tri-Met’s specific ITS goals as well as the agency’s principal mission of improved
mobility for all members of the community. To ensure the deployment of the ITS projects listed in this report are cost effective while at the same time providing Tri-Met’s customers with better service, the agency has developed the mission statement, goals and objectives listed below:
ITS Mission
To ensure the planning, development, and implementation of intelligent transportation systems at Tri-Met and to support Tri-Met’s Strategic Plan’s mission of improving mobility in a growing, compact, urban region.
Goals
Through the deployment of ITS projects, Tri-Met expects to accomplish the following goals and objectives:
ITS focuses on increasing the efficiency of existing transportation resources, in order to improve the overall performance of the system.
PB Farradyne 3 Version 1 2001

1. Increase Regional Mobility – ITS can increase the mobility of all travelers through improved reliability without expanding the physical capacity of the transportation system. In addition, ITS can offer more convenient service to customers, particularly those users with disabilities.
2. Increase Regional System Performance
– ITS offers transportation service
providers the opportunity to better manage transportation demand and supply. ITS can provide Tri-Met with real time information on the
transportation system, which can allow the agency to quickly respond to service disruptions and continue the efficient movement of passengers.
3. Reduce Agency Costs – Both operating and maintenance costs can be reduced through more efficient use of existing resources.
4. Increase Customer Satisfaction – ITS provides transit customers with information before, during and after a trip, eliminating some of the uncertainty of public transportation. ITS projects can also enhance customer satisfaction by improving service reliability as well as reducing travel time.
Objectives
1. Improve customer service both internally and externally through optimized ITS planning.
2. Ensure Tri-Met’s ITS projects are cost effective as well as supportive of each other and the existing ITS infrastructure in the region.
3. Provide a platform for joint venture ITS projects with regional partners.
1.4 BENEFITS OF ITS
Travelers in the Portland region will stand to gain many benefits from the implementation of ITS projects. The evaluation of national ITS programs and ITS user-benefit studies indicate that the Portland region can expect to experience a number of measurable benefits when full deployment is achieved. Some examples of national experience with ITS transit deployment are provided below. Using transit automatic vehicle location, signal priority, computer-aided scheduling and dispatch will:
• Improve system on-time performance;
• Maintain same quality of service with
potential fleet reduction; and
• Enable enhanced flexible/on-demand service with reduced wait time, reduced cost, and increased ridership.
Providing enhanced and sustained access to public agency transportation data will:
• Allow travelers to adapt their travel plans by potentially altering their travel time or route;
• Create a more sustainable business environment for private sector traveler information service providers; and
• Create integrated seamless access to regional data for planners.
The region has already begun to experience the benefits of ITS specifically through the Travelers in the Portland
region will stand to gain many benefits from the
implementation of ITS projects.
deployment of a new bus dispatching system using automatic vehicle location and
automatic passenger count technology. Tri-Met, in partnership with Portland State University, is undertaking a TransNow-sponsored research study to assess the impacts of full deployment of their new bus dispatching system in terms of service reliability and operating performance. The results of the initial implementation are already apparent on the eight routes selected for study. In general, this project has
provided travel time savings, and specific findings are summarized below:
• Tri-Met’s overall on-time
performance improved from 69% to 83%
• Early arrivals declined from 15% to 5%
• Schedules have been improved based on information provided by the Bus Dispatch System (BDS). Some example benefits include:
Line 72 PM peak improvements:
• 62% to 77% on time improvement
• 36% improvement in bus spacing
• Overloaded trips decreased from 24% to 2%
• 60% reduction in reported pass-ups
Line 17 improvements:
• 70% to 83% on time improvement
• PM peak late decreased from 42% to 24%
1.5 ITS PROJECTS
Based on Tri-Met’s goals and objectives, the agency has proposed twelve ITS projects. Ten of these are projects to be deployed internally, while two projects are part of Tri-Met’s regional ITS partnerships. These inter-related core projects will ensure that Tri-Met is able to build upon the region’s existing ITS infrastructure and achieve Tri-Met’s overall mission.

partnerships (and vice versa). TransPort regional projects specific to transit include the following:
Regional ITS Project Descriptions
• OR0158 – Transit Buses as Traffic Probes: Tri-Met buses that travel along a number of key corridors will report travel speeds over selected segments determined to be of interest to the City of Portland and the Oregon Department of Transportation (ODOT). The travel time data will enhance the City of Portland’s and ODOT’s ability to monitor performance and cooperatively manage their facilities within the regional transportation system.
• OR0204 – Regional ATIS Sustainable Business Model Deployment: The deployment of the regional advanced traveler information system would take delivery of transportation information to the next level with information tailored specifically to the needs of individual travelers. The Tri-Met portion of this project would include: (1) collection and preparation of real time operational data, schedule and fare data in a suitable regional format and structure, and (2) distribution of that data through a real time server to businesses willing to provide this information to individual travelers.
1.6 REGIONAL ARCHITECTURE
A key step in developing and deploying Tri-Met’s ITS infrastructure is the identification of the architecture for individual projects as well as the role each plays in the region’s architecture. An architecture defines the functions that must be performed to implement a given service, the physical entities or subsystems where these functions reside, the
interfaces/information flows between subsystems, and the communication requirements for the information flows. Benefits that may be attributed to utilizing an architecture approach in the design, implementation and operation of ITS, include:
• Reduced risk,
• Cost savings, and
• Further development of the “big picture” of the system.
Appendix A provides a general background
on the history, structure and benefits of developing an ITS architecture. In addition,
Appendix A includes a glossary of
architecture terms relevant to Tri-Met’s 5-Year ITS Plan.
Figure 2A: Tri-Met Physical Architecture Connectivity (as an element of TransPort) and Figure 2B provide an overview of Tri-Met’s regional transit architecture including ties to other external agencies.

1.8 PROJECT SCHEDULE
Figure 4 provides a summary of activity over the 5-year horizon of this plan. The
individual project descriptions detailed in Sections 2.0 and 3.0 provide additional schedule milestone data for all projects in Tri-Met’s 5-Year ITS Plan. The majority of Tri-Met’s internal projects as well as the regional projects were initiated in FY2000 and FY2001.
In several cases, the ability of a project to meet its operational objective requires that
another project’s infrastructure is in place. Project interrelationships are shown in Figure 5. As an example of this inter-relationship, the Bus Dispatch System Upgrade project is essential to many
projects, as the enhanced functionality of the new system will be leveraged to initiate or enhance other projects. Transit Tracker, transit probes and automatic announcements of bus stops will all integrate with the advanced functionality of the Bus Dispatch System.

2.1 TM001 – TRANSIT TRACKER (REAL TIME CUSTOMER INFORMATION DISPLAYS)
Table 1 - Background Information
Project ID TM001
Project Title Transit Tracker (Real Time Customer Information Displays) Project
Background
Tri-Met has deployed several advanced ITS technologies to improve the delivery of service on bus and rail. The computer-aided bus dispatch system (BDS) and the rail central control system (CCS) currently display the location and schedule status of all fixed-route vehicles to dispatchers and rail controllers, respectively. This information has considerable value to transit customers, both before they begin a trip and while they are waiting for a bus or rail vehicle to arrive. This project displays real time transit information to transit customers using several communications technologies and display formats to deliver information. It builds on currently deployed systems such as the BDS and rail CCS.
Tri-Met believes that providing actual arrival times of transit vehicles and better information during service disruptions will improve
customer satisfaction. This information will reduce perceived waiting times, help remove uncertainty to travelers, and help them make informed decisions. This, in turn, will allow travelers to use their time more productively.
The "uncertainty" for transit customers varies depending on the expectations of the individual customer. It is expected that all transit users desire predicted bus arrival and inter-modal connection/transfer information (e.g., bus-bus and bus-rail) —Tri-Met intends to address both in this project. Additional information needs include pre-trip planning, and more static information such as fare schedules and park and ride locations. Tri-Met addresses these needs through existing traveler information systems that will be integrated and enhanced with this new real time capability, where appropriate.
Through a series of related capital investments, Tri-Met is now ideally positioned to deploy such a solution using existing infrastructure. This infrastructure can be used for delivery of real time transit traveler information1 to the transit mall, rail platforms, transit centers, and key regional bus stops, as well as trip-planning kiosks and the Internet. At key inter-system transfer points, these real time transit displays will integrate transit information to provide a complete regional transit service.
1
Project Plan The Transit Tracker project will be conducted in three phases: (I) prototype; (II) outreach and user feedback, evaluation of customer benefits and site-selection analysis, and then deployment of initial operational capability; followed by (III) full system deployment. Phase I: Tri-Met will deploy real time customer information displays at three locations that are representative of different types of transit facilities: a rail station (Gateway), a major bus facility (Salmon/5th Avenue) and a selected bus stop with two standard shelters at the intersection of Northeast Martin Luther King, Jr. Boulevard. and Northeast Killingsworth. These prototypes will have the capability to display vehicle arrival times within 1-minute accuracy for vehicles that are less than 15 minutes away. The final stage of the Phase I prototype will focus on an audio component, enhancing the system’s ability to serve customers with disabilities.
Phase II: Tri-Met will conduct an evaluation of the traveler information displays (prototyped in Phase I) and continue a limited deployment of additional displays along the Phase I prototype bus and rail routes.
The focus of the evaluation will be twofold. First, Tri-Met customers will be surveyed to determine user acceptance of the prototype system. This portion of the evaluation will also be used to conduct user
benefits and site-selection analysis to determine the optimal locations in addition to the content and presentation for real time displays in future deployments. Secondly, a technical evaluation will be conducted on the system. This component of the evaluation will be used to identify any technical difficulties encountered during Phase I of the project. It is anticipated that this will significantly reduce the number of technical difficulties experienced in future deployments. A review of the American with Disabilities Act (ADA) compliance and acceptance for the visual and audio components of the site information system will be included in this phase.

Project Plan Continued
Under Phase II, additional display sites will be installed to continue to test system robustness and user acceptance. Up to 15 sites will be added along the bus routes included in the Phase I prototype, and up to 10 rail sites will be added focused on the new service to the airport. Phase III: Tri-Met will complete the deployment of the operational system. It is anticipated that, in addition to equipping additional sites, this phase will allow for content to be added, presentation to be enhanced, and new technologies (e.g., software, hardware,
communications) to be leveraged to the advantage of a reduction in long-term operations and maintenance (O&M) costs.
Prior to additional deployment, the system will be enhanced to account for changes from scheduled service. This work requires integration with the ongoing efforts of the Dispatch Operations Utilities Program (TM008) and with ongoing work for the BDS upgrade. The addition of an enhanced text messaging capability is another prerequisite to additional deployment. It is expected that Phase III deployment will include ongoing efforts to evaluate communication options, including use of Tri-Met communication infrastructure to replace the private Cellular Digital Packet Data (CDPD) system. Continued development and refinement of the prediction algorithms is also anticipated with a focus on methods to accommodate layovers, reroutes and major service disruption conditions, (e.g., snow days). The ability to automatically suppress arrival display information based on driver service disruption input will also be an element of the Phase III enhancements.
It is expected that budgetary considerations may impact or potentially limit the rate of full system deployment.
Project Objective Statement
The overall objective of the Transit Tracker project is to develop and deploy an integrated regional system to collect, process and
disseminate real time transit customer information to the transit mall, rail platforms, transit centers, bus shelters, and via the Internet and other external displays.
Project Risk(s) Programmatic (Scope, Schedule, Resources):
• The multi-phase deployment of the system poses some schedule challenges during the initial prototype stage programmed for FY2000-FY2001. The goal of near-term deployment will be balanced against the need to maximize the long-term benefits of initial infrastructure investments.
• Long-term deployment may be affected if operations and maintenance costs are higher than anticipated, (e.g., vandalism, equipment failure, increasing communication costs). These costs cannot be fully evaluated until additional deployment is completed and data is collected over a longer deployment period.
Technical:
• Transit vehicle location data - The accuracy and continuous flow of real time bus and train location data is essential to the effective and reliable performance of the system.
• Open versus proprietary data interfaces - It would be preferred to have an extensible modular solution that presents data at clearly defined external interfaces; this allows future

External: C-TRAN and Tri-Met Passengers Related Work Internal:
• Accident/Incident Tracking System (ACID) – This project will provide the user interface to allow dispatchers/rail controllers to log adjustments to scheduled service and have on-street displays reflect these changes.
• The Bus Dispatch System (BDS) will be modified to provide more frequent messages (90 seconds) from the vehicles, which are necessary to allow Phase III deployment.
External:
• Tri-Met has the opportunity to examine similar projects that have been deployed both domestically and internationally. Examination of these projects could be accomplished through telephone
discussions, site visits and review of project documentation and literature. These examinations can prove very effective in
identifying lessons learned and best practices when deploying these types of projects. Tri-Met may want to specifically examine the transit components of:
1) SmartTrek -Seattle, Washington: Transit Watch, Bus View 2) NextBus Deployment -San Francisco, California

Operations and Maintenance
Additional ITS infrastructure deployed to support Transit Tracker displays will increase operation and maintenance costs. Properly
operated and managed equipment will be essential to effectively support the functions of this system. Maintenance will be accomplished through a combination of Tri-Met staff and maintenance agreements.
Procurement Options
Several procurement opportunities are under consideration for this project. Common to all is the need to integrate with the OrbCad Upgrade project.
The prototype stage of the project will include a combination of
procurement approaches. This initial project will need to integrate with the existing BDS. Orbital Transportation Management Systems (Orbital TMS), the vendor for this system, is the most effective vendor to
complete the integration. A sole source contract will be negotiated with Orbital TMS to complete the BDS integration.
Full deployment will consider a negotiated sole source contract with Orbital TMS for the central system equipment and installation, and a competitive selection process for field equipment and installation.

29 2.2 TM002 – TRANSIT SIGNAL PRIORITY
Table 1 - Background Information
Project ID TM002
Project Title Transit Signal Priority Project
Background
The Portland region has demonstrated a high commitment to improving transit efficiency and reliability. Transit Signal Priority (TSP) provides a means to continue this commitment. Tri-Met is working closely with the City of Portland and other regional municipalities and counties to identify corridors of interest for the deployment of TSP. This capability will be used to “extend the green” and will be enabled only for buses that are late, as determined by the on-board transit vehicle trip
monitoring and schedule management sub-system. From the Tri-Met viewpoint, this project has the potential for cost savings and regional traveler benefits including:
• Saving the operational costs of a bus and a driver over selected routes;
• Enhancing service to transit riders through system-wide on-time schedule reliability; and
• Operational savings and improved service from optimized schedules as a result of the ability to maintain more consistent headways and eliminating the “bunching” of bus service (congestion impacts on schedule can be partially mitigated and perceived level of service maintained without adding service).
Tri-Met, the City of Portland and local emergency response (e.g., fire) have cooperatively developed a list of initial candidate corridors where transit signal priority would most benefit Tri-Met and coincide with the region’s primary emergency response routes. Within these initial routes, the potential exists to reduce fleet size and utilization due to the travel time savings possible with TSP.
Project Plan The TSP project will be conducted in steps closely aligned and often dependent upon concurrent and future regional projects that deploy or enhance previously deployed ITS infrastructure and capabilities. These aligned projects include improvements to Tri-Met’s bus dispatch software (Bus Dispatch System Upgrade, TM005), improvements and upgrades to the City of Portland’s traffic controller hardware and software, and similar improvements in other regional municipalities. Tri-Met has identified five bus routes where the number of buses necessary to run the route could potentially be reduced due to an anticipated level of travel time savings. For instance, if Route 72 had a 10% reduction in run time, Tri-Met may be able to reduce the number of buses needed to run this route.
From the Tri-Met viewpoint, there are three phases of the project including: (I) pre-activation points, (II) post-activation points, and (III) future enhancements; however, other involved partners must agree upon the phasing.
Phase I (Pre-activation points): This phase centers on the use of existing bus dispatch software functionality to define the area where TSP is allowed in the region. The criteria for use of TSP (“hold the green”) will be determined by the on-board transit vehicle trip monitoring and schedule performance subsystem, with the following main criteria: (1) the bus is inside the City of Portland, (2) the bus is on-route, (3) the bus is currently late, (4) the door is closed, and (5) the engine is running.
An evaluation will be conducted of running time changes based on an analysis of route segments and individual intersections. This
information will be used to determine the effectiveness of specific design treatments and will guide the adjustment of schedules.
Phase II (Post-activation points): The phase I stage of the Bus Dispatch System Upgrade enables use of “activation points”. Activation points serve as a way to further localize the use of the emitter. This phase employs the capability to limit the use of transit signal priority by turning the emitter on only upon approach to an intersection and off after passing through it.
An evaluation of service changes implemented in Phase I will be completed to identify benefits including cost savings and service improvements.
PB Farradyne Version 1 2001
Battelle
31 Project Plan
Continued
Phase III (Future enhancements): The intention in this step is to share bus on-time data with the roadside equipment, and then use this
knowledge to arbitrate and enable more sophisticated TSP between crossing bus routes. This step extends the notion of using bus route schedule performance, current location, (detector to detector) travel time awareness and interaction with upstream queue detection for the purpose of “smarter” traffic signal timing to favor both dominant traffic flows and the included bus route.
The first corridors to be activated will be within the City of Portland, with phase III extending outside Portland into the City of Gresham. Gresham is ready with suitable equipment (Opticom) already deployed and operational. The potential for additional expansion exists because of regional equipment similarities.
Project Objective Statement
The overall objective of the Transit Signal Priority project is to develop and deploy an integrated regional system to reduce schedule variability, which will enable improvements in on-schedule performance, and realize operational cost savings through fewer buses and drivers. Project Risk(s) Programmatic (Scope, Schedule, Resources):
• Each involved agency must agree upon the threshold for when “extended green” is provided.
Technical:
• Replacement/Upgrade of Roadside Controllers - To enable regional TSP, the system of on-street controllers needs replacement/upgrade of hardware and/or firmware. The
deployment schedule and capabilities of TSP are dependent upon this process.
