Bus multi-mode scheduling and along-the-line intersection signal timing collaborative optimization method

Abstract

The invention provides a bus multi-mode scheduling and along-the-line intersection signal timing collaborative optimization method. The method is realized by solving an optimization model, synchronously optimizing rapid bus operation mode selection, departure time of each shift and along-the-line intersection signal timing; the optimization model is expressed by a nonlinear programming model; theminimum total travel time of passengers is taken as an optimization target, various constraint conditions are considered in a combined mode, and the constraint conditions comprise intersection signalcontrol constraints, intersection saturation constraints, passenger waiting constraints and optimization parameter value ranges; according to the invention, aiming at the target uniformity of bus rapid transit scheduling and signal control, three operation mode selections (whole-journey bus, large-station bus and inter-regional bus), departure moments of all shifts and along-line intersection signal timing are integrated into one optimization model for collaborative optimization, so that the operation efficiency of bus rapid transit is improved, and the bus multi-mode scheduling and along-the-line intersection signal timing collaborative optimization method is provided.

Description

technical field [0001] The invention relates to the technical field of road traffic optimization, in particular to a collaborative optimization method for bus multi-mode scheduling and signal timing at intersections along the line. Background technique [0002] With the development of the times, setting up BRT has become an important means for cities to solve traffic congestion problems. The optimization of BRT operation mainly includes two parts: traffic dispatching and intersection signal control along the line. These two parts of optimization are currently done in two phases. But in essence, the two are closely related. On the one hand, the traffic dispatching plan affects the time when the bus arrives at the intersection, thereby affecting the effect of intersection signal control; on the other hand, the intersection signal control is also largely It determines the time for vehicles to pass between stations, thus affecting the execution of the traffic scheduling plan. ...
