In this paper we suggest a game theoretical model for the level of commuting between towns expressed in terms of the travelling distance between the towns. Commuting will be the preferred choice of a worker whenever he can obtain an increase in wages greater than the cost of commuting. Our framework is based on an approach where workers apply for jobs according to a strategy that maximises their expected payoffs (wages minus commuting costs). We also discuss systematic bias in comparing distances between city centres with the actual average travelling difference between intra-zonal and external commuting.
