For performing GIS based Pavement Maintenance & Management Analysis, there are so many softwares used world wide. Among them the leading PMS software’s in practice are:
RoadSoft
RoadSoft, available from the Local Technical Assistance Program (LTAP) at Michigan Technological University, is a GIS-based roadway management system. The software package was developed for local road agencies within Michigan and engineers and managers to analyze roadway information within their jurisdictions. The software uses the Michigan Accident Location Index (MALI) as a physical reference base.
RoadSoft has a road surface inventory module for rating pavement condition using the PASER (Pavement Surface Evaluation and Rating) system. PASER is a simple method of rating asphalt, concrete, and gravel roads developed by the University of Wisconsin’s Transportation Information Center. Manuals filled with pictures detail a one-to-10 evaluation system in which "10" means excellent while "one" indicates a failed road. This system is used to obtain consistent ratings based on the types of wear evident on the roadway surface, such as cracks and deformations. Based on the types of defects, general characteris tics of the roadway, and age of the pavement, PASER makes recommendations for the types of fixes that would be appropriate for the road. There are rating manuals available for concrete, asphalt, and gravel roads.
MicroPAVER
MicroPAVER is a pavement management system developed by the U.S. Army Construction Engineering Research Laboratory and distributed by the Technical Assistance Center at the University of Illinois at Urbana-Champaign. The software contains a full-featured PMS, including manuals for evaluating pavement conditions.
MicroPAVER is a decision-support tool, allowing agencies to systematically determine maintenance and repair needs and priorities. The system also enables users to compare budget scenarios and their effect on pavement networks, and data can be linked to a GIS.
Inspection data from the road network is input into the system’s database. By taking samples of a section of the entire network, MicroPAVER can calculate the Pavement Condition Index (PCI). Information from the PCI is used to accurately predict the overall health of the pavement network. Using pavement life cycle models in the
software, this system can quickly determine which pavements need attention the most, and also calculate the critical condition pavements. (Critical condition pavements are those that are close to the point where they deteriorate rapidly.)
HDM - 4
The internationally recognised Highway Development and Management System (HDM-4) have been used to develop this PMS. Since the size of the highway network is not very large and the analysis period is of medium duration, the ‘programme analysis’
application of HDM-4 has been used for the network-level pavement management analysis. The results obtained through the network-level pavement management analysis have been presented through various applications of GIS.4 This helps in easy identification of the candidate pavement sections, due for maintenance during the analysis period, and the associated details of timing, type and cost of maintenance activities can also be readily determined.
GeoPave
GeoPave can extract and display information that a Pavement Manager requires.
It has Dynamic GIS link to your MTC-PMS system. Easy to use menu selections. Also it has Plug-in extension to ArcView / ArcMap.
The main features of GeoPave are, it can maintain a good Pavement History, it can analyse Maintenance & Rehabilitation Workplans. It can also directly account for Funding Scenarios.
Stantec PMS
Stantec developed a Pavement Management Application (PMA) within their Infrastructure Management System (IMA) software. The Infrastructure Management Application is a tool for the management and graphical display of asset information, structural condition, and other available data for municipal utilities and right-of-way assets, either individually or as a group. IMA is a network planning tool for municipal assets.
Physical characteristics, structural condition assessment, and rehabilitation program development for each asset can be objectively compared with the entire network for planning and rehabilitation and maintenance programs. Information can be analyzed
graphically, or through the use of a GIS. A rehabilitation module analyzes road condition to prioritize rehabilitation activities and budget programming. The system can also recommend maintenance activities, such as crack sealing and pothole patching.
Hansen PMS
Hansen develops asset management software for both the public and private sector. Hansen developed a pavement management system to complement the infrastructure management software developed to assist agencies maintain assets under their control.
The pavement management system is completely customizable by the user.
Working with consultants from the company, the management system is tailored to meet the needs of the user. Hansen works with the agency to determine which inputs are needed to perform analysis, fits the deterioration curves to inputs, and calculates outputs.
CarteGraph PavementView
PavementView pavement management software, developed by CarteGraph Systems, is part of their more general infrastructure management products. Based on concepts introduced by the Federal Highway Administration and the U.S. Army Corps of Engineers, this system integrates data collection, inspection records, asset history, along with performance modeling to accurately assess current and future pavement condition.
PavementView is able to graphically display pavement performance using maps, graphs, or charts. This system allows users to develop queries and reports using all database fields. Users can generate standard or custom reports to assess inventory condition and help manage scheduled and completed
2.5 CONCLUSION
A brief review of the available literature on Pavement management system, Pavement maintenance system and pavement management softwares were done. The international PMS scenario was also discussed.
