摘要：	Given a transport network and fixed demand (expressed as an origin-destination trip matrix), "capacitated demand" is defined as the portion of the given demand that can be served by the network without violating capacity constraints on any of the network's facilities. A significant performance measure of a proposed project in a congested area is the amount of change in the capacitated demand, which is caused by the project: the bigger the change, the bigger the contribution of the project to the productivity of the network and its ability to serve the transport needs. Recently, a modified procedure for the evaluation of transport projects (the Pratt procedure) has been implemented in Israel. It uses capacitated demand as a major evaluation measure. The capacitated demand measure and methods for its estimation are described, as are some of the unique features of Pratt and how the new measure is incorporated into it.
