This paper discusses the influence of the shape of the transportation network on location-allocation results by analyzing the results of the p-median problem solved on 17 systematically generated networks. Networks are generated from a 18 X 18 lattice of points in which each point has the same spatial environment as every other point but are linked in different ways. They basically represent two spatial configurations: regular and radial. A 9-median problem is solved for each network. The impact of the shape of the network on the efficiency and the equity in the supply is then discussed based on six different measures: the average distance, the maximum distance, the total allocation, the location of optimal supply sites, the shape of the market areas and the distribution of the distance frequencies. Finally, changes in the number of sites p is considered in order to investigate the sensitivity of the regularities discussed on the range of p.
