Introduction ​

This page is currently under development.

This section discusses common calibration items used for various facility types and how these items can be addressed in SwashSim.

Network calibration


 * link lengths
 * link horizontal curvature
 * grades
 * stop bar position
 * detector placement (for signal control)

Model calibration

Signalized intersections

Saturation flow rate
 * vehicle spacing within the queue
 * stop gap, by fleet type
 * driver type distribution
 * vehicle acceleration
 * desired accel
 * maximum accel
 * car-following model parameters
 * link free-flow speed

Queue length

Two-lane highways


 * Percentage split between passing and non-passing lanes in passing lane link
 * driver type distribution
 * percentage of driver types considered slower drivers
