2GC SENSITIVITY STUDY. URBAN TRAFFIC CONTROL SYSTEM (UTCS) SOFTWARE SUPPORT PROJECT

The UTCS-1 simulation model, modified for UTCS Second Generation Control (2GC), was used to evaluate the sensitivity of 2GC to five traffic control parameters related to ideal link offsets and timing plan optimization. The simulation testing was conducted under varying traffic conditions on portions of the UTCS Washington, D.C. network. Results, as evaluated against a standardized MOE set, showed that performance can be improved when the predicted speeds used in computing ideal link offsets are multiplied by a section-wide scalar, and this technique was recommended for incorporation into 2GC algorithms.
