13.3.3.3 Base Model Development

The following data is necessary for base model development:
  • Road geometry (lengths, number of lanes, lane assignments, curvature);
  • Traffic controls (signal timings, stop and yield sign locations, right turn on red (RTOR) designations, speed limits);
  • Demand (entry volumes, turning volumes, OD tables);
  • Pedestrian (volumes); and
  • Transit (type, frequency, location of stops)
In addition to geometric and control data, microsimulation models also demand vehicle characteristics. These typically include:
  • Vehicle Mix (% heavy vehicles, % passenger vehicles, vehicle types);
  • Vehicle Dimensions; and
  • Performance Characteristics
Additional information, such as driver characteristics, may be necessary:
  • Driver Aggressiveness;
  • Reaction Times;
  • Desired Speeds; and
  • Acceptable Critical Gaps
