Abstract
Transit network optimization can effectively improve transit efficiency, improve traffic conditions, and reduce the pollution of the environment. In order to better meet the travel demands of passengers, the factors influencing passengers’ satisfaction with a customized bus are fully analyzed. Taking the minimum operating cost of the enterprise as the objective and considering the random travel time constraints of passengers, the customized bus routes are optimized. The K-means clustering analysis is used to classify the passengers’ needs based on the analysis of the passenger travel demand of the customized shuttle bus, and the time stochastic uncertainty under the operating environment of the customized shuttle bus line is fully considered. On the basis of meeting the passenger travel time requirements and minimizing the cost of service operation, an optimization model that maximizes the overall satisfaction of passengers and public transit enterprises is structured. The smaller the value of the objective function is, the lower the operating cost. When the value is negative, it means there is profit. The model is processed by the deterministic processing method of random constraints, and then the hybrid intelligent algorithm is used to solve the model. A stochastic simulation technique is used to train stochastic constraints to approximate uncertain functions. Then, the improved immune clonal algorithm is used to solve the vehicle routing problem. Finally, it is proved by a case that the method can reasonably and efficiently realize the optimization of the customized shuttle bus lines in the region.
Highlights
In recent years, as a special mode of public transport, a customized shuttle bus has been increasingly popular
We propose a hybrid intelligent optimization algorithm based on the immune clone algorithm, stochastic simulation technique, and neural network
Considering the delay of buses caused by the traffic jam, etc., a stochastic travel time constraint is included in the model
Summary
As a special mode of public transport, a customized shuttle bus has been increasingly popular. Taking Beijing as an example, the daily average passenger volume of customized buses (business buses, high-speed rail lines, leisure tourism lines, etc.) has reached 37,000. A customized shuttle bus is a public transit mode, serving the individual demands for the passengers whose origins and destinations, travel time, and service level requirement is similar. A customized shuttle bus is an important part of urban public transit. The stops (including transfer stops) and routes of customized shuttle bus are set up according to the individual demands. The ticket fare of customized shuttle bus is higher than one of the bus and subway, but is lower than one of the self-driving and taxi. Passengers usually need to pay a ticket fare in advance in months or weeks
