MICHIGAN STATEWIDE TRAVEL MODELING SYSTEM. VOLUME I-D. PROXIMITY ANALYSIS: SOCIAL IMPACTS OF ALTERNATIVE HIGHWAY PLANS ON PUBLIC FACILITIES. STATEWIDE STUDIES

In formulating equations and devising techniques to be used in the trip generation phase of the statewide modeling process, a methodology for monitoring the social consequences of implementing alternate highway schemes has been developed. Basically, this technique allows its user to determine how proposed highway plans might affect spacial relationships between social groups and public facilities by calculating the change in simulated driving time which may result from the actual implementation of a specific plan. Since this procedure has been developed within the statewide modeling system, it may use any of its extensive data files which include the Statewide Travel Data Bank, the Statewide Socio-Economic Data File, and the Statewide Public and Private Facility File. This data may be displayed in a number of ways without modification, but the most visually impressive technique has been the use of both two- and three-dimensional computer mapping routines.
