Computer based simulation experiments were designed and conducted utilizing 100 regular commuters from the Sacramento California region. Computer based simulation is used to create a hypothetical traffic network and to function as a data collection tool for collecting dynamic route choice data. Dynamic route choice data under the influence of Incident information, En-route guidance, Pre-trip guidance and Congestion information was collected for a sequence of 20 simulated trial days for each participant.

The simulation screen display is composed of three main windows: a network window, an information window, and an instruction window. The network window displays a hypothetical traffic network, composed of three primary, parallel routes from an origin to a destination. The primary routes are composed of a freeway route and two arterial routes. These primary routes are cross connected with a series of surface streets creating a network of 34 roadway links and 23 intersections (or potential decision points). The travel environment is generated by a stochastic assignment of travel speeds and stop delays to the network links and nodes. A random incident generator is used to assign an incident of random severity to the network for each travel day. The information and instruction windows are used to simulate an in-vehicle information system. Participants use keyboard arrow keys to represent driver route choices in the network for a sequence of 20 travel days (trials).
