Routing of Delivery Vehicles in a City with Access Time Windows

The introduction of access time windows, or periods of the day during which delivery vehicles are not allowed to enter certain areas of the city, is a policy commonly applied by local authorities in order to better reorganize urban traffic flows. However, there are no estimates of the additional costs inflicted on carriers, even though the need for more complicated routes, and often more vehicles, is evident. This paper describes a model for estimating the effect of introducing access time windows in a given city by minimizing the number of required vehicles and the route lengths and comparing them with the required vehicles and routes without time windows. The linear model used for the optimization is described, as well as the solutions obtained for a test network, consisting of a number of nodes and links, part of which cannot be entered during a certain period of the day.
