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
