Abstract

The invention relates to a method of optimizing the running track of a city bus considering energy conservation. The method comprises the following steps: 1) the running interval between the current bus running position and a stop site specified by a running plan is divided to multiple continuous sub intervals according to road features, wherein the road features comprise slope sections, speed-limit sections and intersection sections, and attribute values corresponding to the road features are assigned to each sub interval; 2) according to the divided sub intervals, a city bus driving policy bilayer optimization calculation model considering energy conservation is built; and 3) the city bus driving policy bilayer optimization calculation model is solved, and the optimized track for the running interval between the current bus running position and the stop site specified by the running plan is finally acquired, wherein the optimized track comprises the driving speed, the driving time, the position, the traction force and the braking force of the bus in each sub interval. Compared with the prior art, the method of the invention has the advantages of being dynamic and continuous, reducing energy consumption, improving the punctuality rate and the comfort and the like.

Description

technical field [0001] The invention relates to the technical field of traffic planning, in particular to a method for optimizing urban bus running trajectories considering energy saving. Background technique [0002] The process of rapid urbanization and motorization has led to a rapid increase in the energy demand of my country's urban transportation system. In view of this, the energy saving and emission reduction of urban transportation system has become an important part of the planning, construction and operation of "green city". It is an important means to realize the goal of green urban transportation by choosing the transportation system dominated by public transportation mode and implementing the strategy of moderately advanced development of public transportation. [0003] At the same time, the role of public transportation in urban transportation is gradually increasing, and its energy consumption and emission issues are becoming more and more important. Among ...
