Abstract

Permitted movements in form of lane markings on single traffic lanes can be defined as decision optimization variables at intersection level and can be connected to form a signal-controlled network system. Traffic demand patterns are always given in a OD matrix. It is therefore a new design method to find one reliable set of permitted movements across upstream and downstream intersections to serve the OD demand. A lane-based design concept can be extended for the design of a linked signal-controlled network in the sense that the network configuration and signal timings can be optimized simultaneously. Lane-based model conventionally works in a point-queue system without physical length limits. Incoming vehicles can be queuing along road lanes infinitely. A cell transmission model could be a solution to model spatial queues effectively. With proper signal coordination, vehicles can be released more frequently without exceeding the limited holding capacity of road lanes to avoid overflowing while utilizing green times more efficiently. In this paper, the lane-based design concept and a signalized cell transmission model are integrated to form a new optimization framework. A case study using a pair of T-junctions connecting together will be studied to show the effectiveness of the proposed design approach.
