Flyovers and High Flow Arterial Concept

Abstract

The feasibility of the development of high flow urban arterials by means of an integration of flyover technology with signal optimization is examined. Simulation results, using a modified version of the TRANSYT model, are presented for a case study arterial in the Greater Los Angeles area. These results indicate that the use of prefabricated flyovers, in conjunction with signal optimization, can effectively reduce travel delays and stops along heavily congested major arterials. The resulting high flow arterials can function effectively as “continuous flow boulevards,” even when embedded in relatively dense urban traffic networks.
