URBAN TRAFFIC CONTROL SYSTEM TRAFFIC ADAPTIVE NETWORK SIGNAL TIMING PROGRAM. VOLUME II. DATA BASE INTERFACE AND SUPPORT SUBROUTINES: MODIFIED FIRST GENERATION ROUTINES

This document describes the Traffic Adaptive Network Signal Timing Program (TANSTP) of the Urban Traffic Control System. TANSTP is a second generation traffic control package wherein optimal traffic signal timing patterns are generated on-line as a function of current and predicted traffic flow conditions to minimize average network vehicle delay. In addition to the network optimization routine, the package includes a traffic flow predictor, real-time subnetwork determination routine, a subnetwork interfacing routine, a transition optimization routine, and a local intersection optimization routine which adjusts splits and offsets to minimize delay on a cycle by cycle basis. The TANSTP package uses the executive structure, the detector processing, and the controller command software of the first generation, UTCS software. This is volume 2 of a 3 volume set.
