Bus operators in competition : a directed location approach

We present a directed variant of Salop’s (1979) model to analyze bus transport dynamics. Players are operators competing in both cooperative and non-cooperative games. Utility, like in most bus concession schemes in emerging countries, is proportional to the total fare collection. Competition for picking up passengers leads to well documented and dangerous driving practices that cause road accidents, traffic congestion and pollution. We obtain theoretical results that support the existence and implementation of such practices, and give a qualitative description of how they come to occur. In addition, our results allow to compare the base transport system with a more cooperative one
