• Abstract:
  PeMS is a freeway performance measurement system for all of California. It processes 2
  
  GB/day of 30-second loop detector data in real time to produce useful information. Managers
  
  at any time can have a uniform, and comprehensive assessment of freeway performance.
  
  Traffic engineers can base their operational decisions on knowledge of the current state of the
  
  freeway network. Planners can determine whether congestion bottlenecks can be alleviated
  
  by improving operations or by minor capital improvements. Travelers can obtain the current
  
  shortest route and travel time estimates. Researchers can validate their theory and calibrate
  
  simulation models.
  
  The paper describes the use of PeMS in conducting operational analysis, planning and
  
  research studies. The advantages of PeMS over conventional study approaches is
  
  demonstrated from case studies on conducting freeway operational analyses, bottleneck
  
  identification, Level of Service determination, assessment of incident impacts, and evaluation
  
  of advanced control strategies.
