Simulation of the influence of bus delays in the operation of the Riobamba bus stops

Abstract

Introduction. Public transportation plays an important role in most populated areas. Especially in urban regions, these transportation systems are widely used. But unfortunately, this type of service is often the subject of complaints. Customers are annoyed by "unfair prices", by "bad service" and, in particular, they are annoyed in case of delays. Regarding the particular, this article presents a computer simulation model developed with the Promodel Software. Objective. The purpose is to evaluate, through the simulation technique, how the delays of the buses between stops influence the traffic control devices and indiscipline of the drivers in the operation of the bus stops in the city of Riobamba. Methodology. In the methodological field of simulation, a base model is developed. Before designing this model, we specified the research objective in the form of specific numerical outputs; These are the average number of passengers per bus, throughout the line 2 route system, for each group of delays contemplated in the research hypothesis, as well as the average passenger waiting times (see Tables 1 and 2). Results. The model allows simulated results to be obtained if from the complete system scenario we cancel, for example, the delays due to indiscipline (Dpi) to obtain a new scenario: Dep+Dpdis. Now we have a new version of the model that with the support of ProModel allows us to observe the numerical outputs under the influence of the pair: Dep+Dpdis; and so, with the others. Conclusion. The computer simulation model allows us to conclude that the average number of passengers and their waiting time at stops throughout the system are not affected by each type of delay experienced by buses.
