Transportation Goals and

Objectives

 Goals

• e.g., Improve transportation system reliability

 Objectives

• e.g., By 2020, decrease average annual

traveler delay associated with road closures, major incidents, and

weather-related conditions on interstate highways by 20 percent from 2005

levels.

(11)

ITS Architecture Workshop

Goals and Objectives and the

Architecture

 Regional architecture should be based on operations-related goals and objectives

▬ Ensure architecture and long range plan are guided

by the same operations objectives

▬ Leverage architecture traceability

▬ Use Architecture to identify associated performance

measures and define a framework for performance monitoring

Objectives and

Strategies-Example

 Objective

▬ Improve traffic flows by 50%

in peak traffic periods.

 Operations Strategies

▬ Continue maintaining and updating traffic

signal coordination in response to…changes in traffic patterns

▬ Use changeable message signs to reroute

traffic in high-volume corridors

Operational Strategies and the

Architecture

 Architecture services can point to operational strategies

 Facilitate use by mapping operational strategies from the LRTP to architecture services

▬ Look for gaps and inconsistencies

Objective: Improve traffic flows by 50% in peak traffic periods.

Strategies Service Packages

a. Continue maintaining and updating traffic signal coordination in response to changes in traffic patterns.

ATMS03: Traffic Signal Control ATMS07: Regional Traffic

Management (?)

b. Educate residents about alternative forms of transportation and alternative routes

Education initiatives not covered by ITS, but traveler information service packages could augment that outreach c. Use changeable message signs to

reroute traffic in high-volume corridors.

LRTP and Architecture

Comparison

LRTP  Goals, objectives,

strategies, and projects to achieve it

 Covers at least the next 20 years

 Leads to an intermodal system

 Fiscally constrained

 Must be updated every 4-5 years

Architecture

 ITS Services and projects

 Long term timeframe  Covers multiple modes  Not fiscally constrained  Updated per

maintenance plan

Development of Long-Range Transportation Plan (LRTP)

(19)

ITS Architecture

Workshop

Architecture Use in LRTP

Architecture output could be used directly in LRTP Development of Long-Range Transportation Plan (LRTP) Executive summary material/graphics from the architecture could be appropriate for the LRTP

The Regional Intelligent Transportation Systems (ITS) Architecture for the Kansas City metropolitan region is a specific regional framework for documenting and ensuring institutional agreement and technical

integration for the implementation of ITS projects in the region. The documentation of the regional integration among transportation systems enables comprehensive planning and deployment activities while also supporting the sharing of information and coordination of activities that enables efficient and effective operations.

Architecture Use in

Performance Monitoring

 Architecture defines collection of data from operational systems to support performance monitoring

 Consider regional examples of Archived Data Management Subsystem (ADMS) to automate collection of data from:

▬ Traffic ▬ Transit

▬ Emergency Services

▬ Traveler Information

Archived Data Management

Regional Data Warehouse Monitor System Performance

Architecture Use in Planning for

Operations

Applying the Regional ITS Architecture to

Support Planning for Operations – A Primer Timing of Updates:  Architecture updated prior to LRTP update  Architecture updated after LRTP update

 Both updates at same time

(23)

ITS Architecture Workshop

Usefulness of the

Regional Architecture

 In supporting long range plan development ▬ Current regional architecture may have limited usefulness ▬ Revise architecture outputs during update cycles to increase usefulness Long Range Plan Strategies, Evaluations, Documentation Original outputs Updated outputs Regional Architecture

ITS Architecture Workshop

Regional Architecture

-Making it Useful

 Explicitly connect architecture needs and services to objectives and strategies

 Describe mid-long term projects in language suitable for the plan (e.g. as “strategies”)

 Create executive summary material/
