Abstract:
The combined optimization design idea of simultaneously adjusting bus-only lane location and transit route network based on transit corridor was proposed, and two-level optimization model was designed to find the optimal combined design approach of bus-only lane location and transit route network. The combined optimization approach of bus-only lane and transit route network was solves by using the upper-level model with the minimum travel cost, operating cost of bus and maximum operating efficiency of road network, and the passenger flows of car and bus were distributed by using the lower-level model with the minimum generalized travel cost. The genetic algorithm was used to solve the model, the effectiveness and practicability of the model were verified through a case, and the sensitivities of key parameters of the model were analyzed. Analysis result shows that after optimization the routes cover 100% of bus sites and 63 road sections, the coverage proportion of road sections is 76%. The total travelling cost in route network is 525 147 yuan, and decreases by 20% compared with present cost 655 282 yuan. The efficiency target value of transit route network is 234 person-times per hour, and increases by 31% from 179 person-times per hour available now. Obviously, the combined optimization approach of bus-only lane location and transit route network based on transit corridor is obviously preferable to the approaches of simply optimizing bus-only lane location and simply adjusting transit route network, and gives play to the network benefits of transit corridor better. 6 tabs, 6 figs, 26 refs.
