• Abstract:
  Automated Traffic Signal Performance Measures or ATSPM represent a state-of-the-art traffic signal management solution. After over 20 years of collaboration among federal agencies, state agencies, academia, and industry, the ATSPM system is increasingly being accepted and adopted by agencies. While the ATSPM deployment is scaling up, new challenges are surfacing. A main challenge is the increasing gap between traffic signal design and traffic signal operations. Traffic signal planning and design still follow the traditional approach instead of the new ATSPM approach due to a lack of the needed data. Once the new traffic signal timings are deployed in the field, they will receive much more extensive evaluation using the ATSPM method. Another challenge is that deploying the ATSPM system takes lots of resources even though the software may be free. This situation results in limited access to the ATSPM system among the stakeholders. Other challenges include the high demand for detectors, operational and maintenance complexities, etc. These issues will likely become hurdles for agencies to scale up their ATSPM deployment. This research aims to address the above issues to facilitate TxDOT’s stage-wide ATSPM deployment. It has achieved three goals: • Provided a practical ATSPM-In-the-Loop simulation solution to introduce the ATSPM method into the traffic signal design stage. This solution will not significantly increase project costs. • Provided a pre-deployment mechanism for stakeholders to evaluate unconventional traffic signal solutions using the ATSPM system, like adaptive, traffic signal preemptions etc. • Provide a training platform for stakeholders to explore new ATSPM solutions.
