A time-dependent model for commercial activity location and travel demand is developed based on the assumptions that instantaneous interzonal shopping travel demand can be described by a gravity formulation, whereas the incremental individual zonal retail space allocations are such that they...

A "user-equilibrium" trip distribution/assignment model is developed, which includes an endogenous destination cost for the conduct of a given activity at the destination. Destination costs are determined endogenously, as increasing functions of the number of trips to the destination. Link...

A classical equilibrium model of shopping travel distribution is revised and extended to include endogenous travel costs and zonal prices of goods sold. At equilibrium, revenues in each zone are equal to the cost of operating retail facilities, which is a function of the level of sales, while...
