Bus Schedule

Improving the operation of urban public transport scheduling level is an important way to increase the attractiveness of public transport. In this paper, from the interests of bus passengers and bus companies, A model that maximize the benefit of company based on a certain benefit of passengers is attempted to be developed. Passenger waiting time, bus capacity and other related factors as the main variables were considered in this study. An algorithm based on genetic algorithm was developed to solve the problem efficiently. By utilizing the transit module of the transportation planning software TransCAD, a route system was established based on the bus line 183 in Nanjing. Thus, the bus schedule is created and the optimization results could be dynamically displayed.

The article describes the main features of the optimization model, which can be used to design a network of urban public transport. Design tasks can be solved using a model that allows you to redesign a part of the network or the entire network as a whole. The model consists of an additive procedure in which the decision to include a route in the network or increase the interval of movement is based on an economic criterion - an estimate of the Lagrange multiplier for the optimization problem. The main advantage of the model is that the design problem is solved only through the optimization process. The optimization process remains understandable, and the model does not require the use of special software. The simulation results are given in the article.

The Relationship

Problem. Currently, there exist two main types of service on public transport routes – headway-based and timetable-based. They differ by the frequency of service at the stops and by the information available for passengers. The required frequency of service significantly affects transport operator costs and passenger travel time which, in turn, influences the cost for a passenger. One of the ways to reduce costs for both parties of the transportation process is to make a reasonable choice of the type of service or switch between the types during the day depending on the passenger flow volume. Goal. In the paper, to justify the choice of between the types of service, the cost of public transport vehicles operation and the losses of passenger travel times are taken into account. Methodology. The developed way of making a choice about the type of service allows increasing the efficiency of urban public transport due to reducing the passenger waiting time by switching from the headway-based service in rush hours to timetable-based service in the periods of passenger flow volume decline. Results. The relationship allowing making a decision about the type of service on the route is developed. It allows to correctly introduce the type of service which will ensure the balance between the transport operator and passenger costs. Originality. The developed approach to make a decision on the type of service allows reducing the passenger waiting time by switching from headway-based service in rush hours to the timetable-based service in the periods of decline in passenger flow volume during the day. Practical value. The results of the research based on the survey data allowed estimating the numerical value of the headway at which it is expedient to switch to the timetable-based service.
