Abstract

The invention relates to a bus dynamic trajectory optimization method considering comfort, energy saving and emission reduction. The method comprises steps that S1, the feature information of a to-be-optimized bus is obtained; S2, the information about intersections through which the to-be-optimized bus passes by is optimized; S3, the vehicle speed guiding strategy is determined based on the bus feature information and the intersection information; S4, after the end of a bus stop, a current passenger loading factor of the bus is determined, whether the current passenger loading rate is greaterthan the set threshold is determined, if yes, a S5 is performed, otherwise, a S6 is performed; S5, a trajectory optimization model is established through utilizing the trajectory optimization strategy considering the passenger comfort in combination with the determined vehicle speed guiding strategy, and the model is solved to obtain the optimization trajectory of each sub interval; and S6, the trajectory optimization model is established through utilizing the optimal trajectory optimization strategy of fuel consumption and the determined vehicle speed guiding strategy, and the model is solved to obtain the optimized trajectory of each sub interval. Compared with the prior art, the method has advantages of considering the passenger comfort and vehicle fuel consumption.

Description

technical field [0001] The invention relates to the technical field of traffic planning, in particular to a dynamic bus trajectory optimization method considering comfort and energy saving and emission reduction. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of national income and living standards, the number of urban motor vehicles and residents' travel volume has increased rapidly. In order to deal with problems that affect urban development, including traffic congestion, environmental pollution, and energy consumption, various regions have actively implemented a strategy of giving priority to the development of public transportation and vigorously developed urban public transportation systems. [0003] At present, the bus driving process is mostly based on the driver's experience. There are large differences between drivers with different experience and technical levels, and there is a large room for optimi...
