Bi-level Programming Model for Planning Urban Micro-circulation Transportation Network

The concept of urban micro-circulation transportation was defined. Micro-circulation transportation can shunt traffic of arterial roads, avoid the congested road segments, and so smooth the whole transportation network. The bi-level programming model for designing micro-circulation transportation network was proposed. The upper-level problem is to minimize the total reconstruction expense and land occupancy of the micro-circulation transportation network under the constraints of saturation, the reconstruction space of branch roads and the number of intersection points of micro-circulation roads and arterial roads; the lower-level problem is an user equilibrium traffic assignment model to describe drivers¡¯ route choice behavior. By this model which branch roads are picked out as traffic-shunting channels and their required capacity after reconstruction can be determined. Micro-circulation transportation network design problem includes both discrete variables and continuous variables. This paper developed a method of converting two groups of variables (discrete variable and continuous variables) into one group of new discrete variables, thus converting the mixed network design problem into a new discrete network design problem with multiple combination of variables, and the solution method using genetic algorithm was proposed. Finally an example demonstrated the application of the model and algorithm.
