With the amount of attention that is given to the development influencing nature of transportation investment in many planning studies, some additional conclusions seem appropriate. First, transportation i only one factor that influences development decisions and, hence, land-use impacts. In general, land development impacts near transportation facilities are caused by many economic, govemmental and social factors including (l) regional demand for new development; (2) availability of developable land; (3) complementary local government actions (e.g., zon ng and land-use plans): (4) appropriate adjacent land uses; and (5) attractive sites for development. Public officials can, and have, used tax incentives, financial support, and technical assistance programs to influence developers' decisions as to the location of proposed projects The use of government influence in this way can indeed affect the land-use configuration at a particular site and perhaps more broadly if applied consistently. Second, transportation planning and investment should be coordinated with land-use planning. In Canada and in many other countries, transportation i regarded as a land use and is fully integrated with general urban planning. Although this is enerally not the case in the United States, such coordination is essential for the development of a transportation investment program that meets the development needs of an urban area. Third, the development of land in market-oriented economies is mainly the responsibility of private entrepreneurs and developers. Thus, the feasibility of new
