Vissim Detector Data Aggregation and Ramp Metering plugin

The plugin utilizes the API functions from VISSIM to perform the following functions:

  • Detector data aggregation at a predefined time interval (basically, you can compare simulated detector data against observed detector data)
  • Ramp metering control based on the following logic:
    • SATMS (demand capacity logic), deployed in District 7 (Los Angeles County) and District 12 (Orange County) of Caltrans
    • SDRMS (volume control and occupancy control logic), deployed in Caltrans District 11 (San Diego), District 8 (Riverside and San Bernadino), District 3 (Sacramento)
    • ALINEA, adaptive ramp metering algorithm proposed by Prof. Markos Papageorgiou
