SIGNALIZATION OF DIAMOND INTERCHANGES

In this article the authors describe a research project in the Federally Coordinated Program of Research and Development in Highway Transportation (FCP) on the signalization of diamond interchanges. This project was performed by the Federal Highway Administration in cooperation with the California Department of Transportation and the city of Los Angeles. Initial research provided simulation and analytic models for use in developing the signalization of diamond interchanges. Field implementation of new methods for fixed-time control showed a reduction in travel time, stopped time, and number of stops. Furthermore, the total delay was reduced by 25 percent when a real-time system was used to control the traffic signals.
