ATSPM Challenges

Slide Reads Challenges with Standard ATSPM Deployment, Standard ATSPm Deployment: High-resolution controllers, data probe and FTP configuration at Signal Boxes. Challenges: Upgrading to high-resolution controllers requires significant investment, $4,000 to $5,000 dollars per intersection. Opportunities: Centralized event logs of Adaptive Signal Control Technology systems. Rapid expansion of ASCT systems. Objectives: Integrate ATSPMs and Adaptive Signal Control Technology )ASCT) systems to produce ATSPM performance metrics. Policies: Dynamically adjust the signal timing in real time in practice. Timing changes (long-term) versus ASCT (real-time/short-term).

In order to avoid costly infrastructure costs of replacing ASCT systems for ATSPM equipment, the researchers devised a method to make use of existing, deployed intersection systems.
