Project Synopsis

Title: Implementation of a Traffic Signal Maintenance & Management System
Project Researcher: Gary Jasper, CarteGraph Systems
Project Manager: Christina Bennett
Research Period: 1/5/2005 - 10/31/2006
Cost: $25,425.00

Problem Statement:

Traffic signals on the state highway system are owned by the South Dakota Department of Transportation (SDDOT), but are normally maintained by local government entities. Currently, the SDDOT does not have a database containing the inventory of traffic signal components or equipment, nor does the Department have any reliable means to verify, track, review, and record an inventory of traffic signal maintenance along state routes. The SDDOT has determined the need to implement a traffic signal management and maintenance system to address the deficiencies that currently exist in regard to maintaining an equipment inventory and the tracking maintenance activities.

A recently completed research project, SD2003-01, "Improved Traffic Signal Maintenance & Management", basically redefined the policies, agreements, and procedural standards surrounding traffic signal management and maintenance activities at the Department. The development of new traffic signal maintenance and management documentation, including maintenance inspection checklists and signal inventory items, have essentially provided the system requirements for a traffic signal management and maintenance system at the SDDOT.

It is anticipated that there will be approximately 6 primary users of the traffic signal maintenance and management system at the SDDOT. This includes 4 Region Traffic Engineers at the Aberdeen, Mitchell, Pierre, and Rapid City Region offices, a Traffic Engineer in the Central Office - Operations Support, and a Traffic Design Engineer in the Central Office - Road Design. Local Government Agencies (LGAs) will be responsible for supplying much of the signal maintenance data since they are responsible for the actual maintenance activities on traffic signals. It has already been defined that LGA data can be submitted, and treated in a wide variety of formats according to community size, number of signals, communication capabilities, etc. Essential system testing activities will be focused on maintaining an inventory of equipment and components for all traffic signals on the state trunk highway system (totaling approximately 270 traffic signals), as well as tracking and keeping records of all traffic signal maintenance activities as defined within the newly developed "SDDOT Traffic Signal Annual Maintenance Inspection Checklist."


Research Objectives:
1  To fully assess the feasibility, and then perform a test implementation of a traffic signal maintenance and management system at the SDDOT.
2  Develop an implementation plan, based on the results of the feasibility assessments and testing results, for full deployment of a traffic signal maintenance and management system at the SDDOT.
3  Install and implement a traffic signal maintenance and management system that meets the functional requirements of SDDOT system users, as well as the system requirements defined by the SD Bureau of Information and Telecommunications (BIT) information

Research Tasks:
1  In conjunction with appropriate SD BIT personnel, perform a thorough review of the South Dakota computing environment and SD BIT standards with the primary focus of performing a pilot installation of SignalView software. The ultimate pilot test is pe
2  Perform a thorough review of the SDDOT's conceptual implementation of a traffic signal maintenance & management system that essentially derived from the approved recommendations of SDDOT Research Project SD2003-01, “Improved Traffic Signal Maintenanc
3  Upon review and acceptance by SD BIT and the SDDOT of a system testing installation plan, install the test configuration as identified in Task 1, above, and coordinate the effort in a close working relationship with appropriate SD BIT personnel. Also
4  Develop, submit, and provide an overview of a plan that indicates how Cartegraph support personnel, SDDOT Signalview users, and BIT support personnel will interact and document findings during pilot testing. The plan will ensure that: a) SDDOT and SD
5  Provide basic training to SDDOT and SD BIT personnel who will be involved in the system testing whereby the primary emphases' will be on SignalView software usage, functionality, and any extended capabilities that might be relevant to SDDOT needs.
6  Initiate testing and provide continuous phone or Internet support to pilot test users, as well as regular contact with SD BIT to assure optimum workability of SignalView during the testing phase. CarteGraph should also be prepared to provide on-site
7  At the end of testing, not to exceed 90 days, assimilate all results of the testing phase into a set of system specifications that define a full implementation of CarteGraph's Signalview at the SDDOT, including all associated costs of said implementa
8  Conduct a meeting with the SDDOT and SD BIT to discuss and refine the final system specifications, including estimated costs, whereupon the SDDOT will perform a system implementation feasibility assessment and notify CarteGraph within 2 weeks on whet
9  Install and implement the Signalview system according to the specifications defined in Task 8, above.
10  In coordination with SDDOT users and SD BIT personnel, perform system testing to ensure installation is satisfactory and complete.
11  Provide on-site system training to all SDDOT Signalview users.
12  Initiate on-going system support and maintenance services, renewable annually.
