For the analysis of the bus-stop problem there have been partial advances in the development of ad-hoc tools. These have taken the form of simulation models for bus operations at bus-stops or along corridors. However, itis necessary to have a deeper understanding of particular interactionsto take better decisions in the context of designing public transport systems.This constitutes the aim of the research in progress. Its objectives canbe summarised as follows:
(a) to investigate further those phenomena that occur withinand between bus-stops and its surrounding area, starting from a conceptualization of the problem;According to the above objectives, a structure for investigating the complete problem of bus-stop interactions has been defined. Then, the problem hasbeen focused on analysing specific interactions that occur within complexbus-stops, because it appears to be the next necessary step in the comprehensionof this subject. As a broad working hypothesis can be stated that undercertain operational conditions interactions have adverse effects on theperformance of the whole bus-stop which can be managed by appropriate designs.In order to test the hypothesis and discover cause-effect relationships,a parallel modelling framework is being developed. This seems to be suitablegiven the nature of the problem, which involves many independent processesoccurring at the same time. Modelling strategies are being explored andexperiments are been considered. Over these issues this research will progressin the future.
(b) to improve or develop modelling approaches related to the behaviourat bus-stops, as well as to perform some experiments that allow us to understand better that behaviour;
(c) to provide some guidelines to assist in the design of bus facilities, following the results obtained in (a) and (b).
