THE COMMUNITY AGGREGATE PLANNING MODEL

As urban transportation studies have begun to reevaluate existing system plans, planners have seen a need for more rapid and efficient tools for system evaluation. This need has been accentuated by increased public awareness of environmental and social consequences of transportation policy-related decisions and by the demand for increased citizen participation in the planning process. The community aggregate planning model attempts to fill this need by operating at the community level, by using easily obtained inputs, and by directly producing usable evaluation criteria. The model requires only simple inputs. System capacity is given by the freeway and surface-arterial lane miles (kilometers) in each community. Connectivity is assumed to be ubiquitous for arterials and is simply represented for freeways and expressways; there is no need to code extensive conventional networks. The only required demand measure is the number of vehicle trip ends in each community; this reflects externally derived transit- automobile modal-demand analysis. The model also combines, in one efficient computer package, modules that, with one pass, generate a regional system-sensitive vehicular travel demand, distribute the demand to the arterial and freeway systems in each community, and compute a full range of useful evaluation measures describing the direct and indirect consequences of the test alternative for each unit-community analysis. The output measures are comprehensible to planners, citizens, and decision makers and do not need intermediate summarization or interpretation. In addition, the model is designed to output performance measures for two alternatives simultaneously and thereby facilitates the comparative analysis of base and future alternatives. /Author/
