Modéles De Distribution Spatiale Tenant Compte Des ItinéRaires

Abstract

In this paper two extensions of the maximum entropy distribution model are examined. The first extension consists of substituting the total travel cost constraint by constraints derived from the information on utilized paths and traffic counts. The resulting model is particularly useful for uncongested networks. The second extension is based on the assumption ofthe existence of an equilibrium traffic pattern. The resulting model provides a maximum entropy distribution, which, assigned on the network, reproduces the traffic counts. The numerical results obtained are encouraging and show that this model may be advantageously applied to networks with several alternative paths between any two given points with unknown utilization rates.
