Integrated Traffic Data System (ITDS) is a microcomputer-based system designed to allow traffic engineers to store, maintain and update traffic network information in a centralized data...
Traffic Simulation at Unsignalized Intersections Using GPSS
This paper develops a simulation model, based on actual field data, that simulates the minor street left turn movement at a STOP-controlled T-intersection. This simulation model predicts...
Traffic Simulation and its Graphic Presentations
A computer simulation program for traffic signal timing design was developed. The program can provide some appealing graphic presentations not only of input data but also of output results....
Microcomputer Model for Estimating LOS on Urban and Suburban Arterials
In the 1985 Highway Capacity Manual (HCM) [1], level of service (LOS) designation for urban and suburban arterials is predicted on the average travel speed by section and for the entire...
Knowledge Based Expert Systems for Post-Incident Freeway Traffic Control
A knowledge based expert system for rerouting traffic upstream of an accident or other capacity-reducing incident on a freeway network is developed and compared with results obtained using...
Synthetic O-D Microcomputer Trip Table Packages
Three microcomputer models for synthetic estimation of origin-destination trip tables are compared based on theoretical foundations, implementability, and operating performances. Each...
