Urban population density may influence transportation demand, e.g., as expressed through average daily vehicle-kilometers traveled in private motor vehicles per capita. In turn, changes in transportation demand influence total passenger vehicle emissions to which populations are exposed....

This study demonstrates the sequential linking of two types of models to permit the comprehensive evaluation of regional transportation and land use policies. First, we operate an integrated urban model (TRANUS), which represents both land and travel markets with zones and networks. The travel...

Transportation planners have traditionally considered land use policy to be outside their purview and have generally accepted existing (or proposed) land use policies and patterns as a given. That attitude changed, however, with the passage of the Intermodal Surface Transportation Efficiency Act...

In this issue of ACCESS, we examine how land use considerations can improve transportation planning. Transportation planners have traditionally sought to maximize mobility by supplying better roads and common carriers, thus making it easier to move around. Seldom have they sought to improve the...
