Abstract

The invention relates to a bus moving trajectory optimization method considering the comfort level. The method includes the following steps that S1, to-be-optimized bus characteristic information is obtained and includes a bus moving route, the current position of a bus, current speed and bus information; S2, the information of a to-be-optimized bus passing through an intersection is obtained, wherein the intersection information includes an intersection location and an intersection traffic light timing information; S3, based on the bus characteristic information and the intersection information, the time interval of the vehicle reaching the next intersection is calculated, and a speed guidance strategy is determined according to the relationship between the time interval of the vehicle reaching the next intersection and the corresponding time interval of a red light at the intersection; S4, according to the determined speed guidance strategy, a trajectory optimization model considering the comfort level of bus moving is built, and the optimal trajectory of each subinterval is obtained by solving the model. Compared with the prior art, the method can improve the comfort level of passengers, and thus the level of public transport service is improved.

Description

technical field

[0001] The invention relates to the technical field of traffic planning, in particular to a method for optimizing a bus running track considering comfort. 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 such as traffic congestion, environmental pollution, and energy consumption that affect urban development, various regions have actively implemented the 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 optimization in the bus driving process. In orde...
