QUEUING AND SEARCH DELAYS DUE TO GASOLINE STATION CLOSINGS: SIMPLE EQUILIBRIUM FRAMEWORK

This paper presents a simple framework for modeling the delays involved in searching for an open gasoline station and queuing at the station in urban areas. It includes an elastic response of the demand for gasoline and solves simultaneously for the number of users per unit of time and the search and queuing delays. The search-time model is based on simple geometric probability considerations, open gasoline stations are modeled as M/G/1 queues, and the demand curve is assumed to be a simple two-parameter curve. The model is concerned only with aggregate averages and not with detailed distribution of the delays. The solution is demonstrated, in a numerical example, as a function of the percentage of open gasoline stations and a demand sensitivity parameter. The example is focused on relative changes (in the output parameters) only, because the model is not calibrated to a particular urban area. (Authors)
