Abstract: In order to reduce the travel cost of citizens in big cities and relieve the pressure on the capacity of public transportation enterprises, this paper proposes a bus scheduling optimization algorithm of smart transportation OD (Origin Destination). Based on the prediction of bus OD passenger flow and the scheduled departure time interval, the derivation theory of bus OD passenger flow is used to construct the bus scheduling optimization model of smart transportation OD. By obtaining personal OD data, using single line bus OD method, city bus OD matrix is calculated. According to the city's public bus travel OD calculation results, the bus scheduling model is solved, and the problems of multi-objective planning and bus network optimization in smart transportation scheduling are solved. Through the simulation test, the evaluation index of smart bus scheduling plan is analysed and the proportion of vehicle operation efficiency is calculated. The simulation data of automatic bus scheduling is 79% and the actual operation data is 73%. Statistics of the vehicle proportion in peak hours and all day operation times are as follows: the simulation data of automatic bus scheduling is 36.75% and the actual operation data is 37.37%. The proposed model meets the requirements of evaluation index for the smart public transportation plan. The real cases prove that the model and algorithm are practical and reliable. |
