Freeway Performance Measurement System (PeMS)

This dissertation describes California's Performance Measurement System (PeMS). It first describes PeMS web-based applications, defining PeMS performance measures and explaining their roles in transportation management. PeMS applications, as well as an advanced traveler information system (ATIS) application and loop diagnostics applications are described. The study then demonstrates the potential of PeMS for academic research by describing three statistical studies on capacity analysis of bottlenecks, travel time variation in Los Angeles, and the impact of incidents on overall delay. The components that comprise PeMS, including data collection, sensor technology database structure, and system architecture of PeMS applications are described. The study concludes with a description of several PeMS algorithms that correct data errors, calculate speed from single loops, predict travel times, and find shortest routes.
