Abstract:
The objective of this project was to develop a custom toolbox for monitoring and troubleshooting operational issues and faults at signalized intersections and diamond interchanges, and for providing a mechanism to facilitate signal timing optimization using third-party optimization programs. This report describes work conducted by Texas A&M Transportation Institute (TTI) researchers to achieve the above objectives, which resulted in three software modules: (1) a monitoring module that uses National Transportation Communications for ITS Protocols (NTCIP) messages to monitor and record real-time statuses of events in a traffic controller and logs collected and processed data for later use, (2) an analysis module that generates various easy-to-interpret reports to allow assessment of controller event data, and (3) an update module that reads optimized signal timing from a selected universal traffic data format (UTDF file) and uses NTCIP messages to download these timing data to a controller. The report also describes in-lab and field testing that researchers conducted to verify the operations of these modules.
