This page lists in alphabetical order the major data items and external entities used in the simulator.

 Author:: The creator of an incident script.

 CAD Display:: A graphical presentation of events occurring in the simulation.

 CAD Message:: A communication from the CAD Server describing status of CHP Units and inident events.

 Developer:: The person with knowledge of the traffic model that can provide details of traffic flow for use in the simulation.

 Highway Map:: The config/vds_data folder contains a reference file of input data giving the locations of all highway sensors in a certain region of the state highway network.  Each line in the file identifies one sensor location and contains these fields: FWY	Dir     POSTMI	LDS_ID	VDS_ID	LOOP_ID LOC    LANE LOOP_LOC      	PARAMICS_NAME  PARAMICS_LANE

 Highway Network Display:: An ASCII representation of the traffic events for verification by the developer.

 Highway Network Status Info:: The state of the highway model.

 Incidents:: One or more highway incidents being simulated such as an overturned produce truck or a vehicle collision.

 Incident Script:: An xml file describing all the incidents to be presented during a simulation run.

 Phone Numbers:: Phone numbers of relevant agencies for reference by trainees during a training session.

 Properties:: Configuration settings by which developers can control various parameters of the simulation.

 Simulated Traffic Sensor Data:: Data representing simulated highway traffic sensors that provide realtime state of traffic conditions at specific points in the highway roadway.

 Traffic Conditions:: The state of the traffic network in a form ready for graphical display.

 Traffic Events:: An internal representation traffic flow details. 

 Traffic Flow Details:: Human readable but encoded form of stopped, slowed, or free flowing traffic that will be incorporated into the highway model.

 Trainee:: A Cal Trans dispatcher trainee using the simulation.
