Sustainable Operation of Arterial Networks
PI: Pravin Varaiya, UC Berkeley
Abstract: We propose to design a suite of techniques that will: (1) increase the throughput of the urban transportation network; (2) make traffic behavior predictable, reliable and efficient; and (3) reduce intersection accidents by preventing red-light running and rear end collisions. This proposal addresses Goal 4 (System Performance) of the Caltrans Strategic Management Plan and its objectives: reducing peak period travel times and delay through intelligent transportation systems and operational strategies; improving integration and operation of the transportation system; and developing integrated corridor management (ICM) strategies. This proposal also indirectly addresses Goal 3 (Sustainability, Livability and Economy) of the Strategic Management Plan, as the proposed techniques will improve the efficiency the transportation and the freight systems and reduce pollution from operation of transportation infrastructure. The main focus of the project is arterial traffic management that occurs on three levels: (1) at the vehicle level the car speed and headway are adjusted to increase throughput and safety; (2) at the road link level signal timings are optimized and special lanes re-allocated, e.g. bus lanes may be opened for everyone when necessary; and (3) at the network level traffic demand is managed via route advisory, day-to-day intersection timing adjustments, and traffic information dissemination.
