The paper deals with the problem of the impact analysis of mass transit system timetables parameters on the modal split, which is reflected in a traffic model. A typical criterion of selecting transport mode in this kind of model is a journey time, which is mostly moderated by an individual transport. It mostly results from infrastructure parameters and the travel demand, both defining the traffic conditions in the whole transport network. Considering mass transit system, a journey time derivates from timetable (or frequency of running), which is first defined by the operator and then reflected in the traffic model. As a consequence, this modelling practice makes the journey time via mass transit system independent from general traffic volume reflected in the model. Thus, the authors have started a pilot study on this phenomenon. They have proposed a relationship between an acceptable change in traffic conditions of the traffic model and a resulted difference of a journey time of public transport vs. individual one. On this basis, the concept of a stable modal split was formulated, and it is experimentally tested. |
