SIMLAB is designed to support a wide range of traffic control logics, including pre-timed signal controls, traffic adaptive controls, metering controls, and control strategies in response to incidents. Traffic regulation and route guidance are conveyed to individual drivers in the simulated network via various devices and information means (e.g., VMS, in-vehicle units, etc.). When vehicles in the network view a signal or sign, they respond to the given control and route guidance according to the behavioral models. For example, delay at a particular downstream bottleneck can be shown on an upstream variable message sign. Drivers who view the message will either change their path or continue on their current path.
