Effects of Passage Restrictions for Heavy Vehicles on Tour Trips in Urban Networks

one of the differences of freight modeling to passenger modeling is its complex pattern in supply chain process. Probability of tour is a function of network and impedances among destinations and fleet constraints. It is obvious that in network with passage restrictions (in residential streets and collectors) for heavy vehicles, the number of destinations in each tour (tour length) will increase and instead it may increase the cost of the users. This paper discusses about activities of major agents, in freight movement, in our case study which is the second major city in Iran. Cost of shippers and number of destinations in tour, will be compared in two states. The first state is no restriction and the second state is passage restriction in some residential streets.
