This paper summarizes the development of a freeway model and an arterial model and their application is assessing the impacts of traffic-management strategies. Previously developed models were modified to include energy and air-pollution impacts, and to include spatial and modal demand shifts due to freeway and arterial traffic-management strategies. The new freeway model was applied to a 20.2-km (12.6-mile) inbound section of the Santa Monica Freeway in Los Angeles during the morning peak period. Priority entry-control operations were found to be more effective than normal entry-control operations although an exclusive bus and car-pool lane was more effective than an exclusive bus lane. The new arterial model was applied to an 8-km (5-mile) section of Wilshire Boulevard in Los Angeles for two-way traffic operations during the afternoon peak period. Optimum signal-control strategies under existing street design conditions were found to be more effective than optimum signal-control strategies combined with either reversible lanes or exclusive bus-lane operations. Signal-control strategies under existing street design conditions were determined on a passenger basis and on a vehicle basis; these strategies resulted in a trade-off between passenger-time savings and reduction in air pollution and fuel consumption. Reversible-lane operations were found to be more effective than exclusive bus-lane operations. Future areas of research are identified. /Author/
