DEVELOPMENT OF A TRANSYT-BASED TRAFFIC SIMULATION MODEL (ABRIDGMENT)

The Level II urban traffic simulation model contained within the TRAFLO traffic simulation package is described. Level II is a tool by which to evaluate transportation system management strategies and is an adaptation of the traffic flow model embedded in the TRANSYT signal optimization program. The Level II model describes traffic flow patterns in the form of statistical histograms. These histograms express flow rate as a function of time on each network link, stratified by turning movement; buses are treated in somewhat more detail. Platoon dispersion is treated explicitly, and service rates at an intersection are related to turning movements and to the signal control. The flow model used in TRANSYT is discussed along with the modifications and extensions that were incorporated in Level II. Data requirements and the measures of effectiveness generated by Level II. Data requirements and the measures of effectiveness generated by Level II are presented. Model validation results and program efficiency are also discussed. (Author)
