Transit System Planning
To effectively model Transit Demand, a simulation program capable of using both a gravity model and a network model is required. Effectively, a Travel Demand Model simulator such as CUBE. Use a familiar model, but make it possible for agencies to "Be the DoT, not the BPR". (Department of Transportation, not Bureau of Public Roads). Map each type of transit to a functional class of road. Treat Light Rail as a highway, regional buses as arterials, flex routes as local streets. Connect centroids only to places within walk distance. Weight propensity to walk inversely to distance. Include a coefficient for quality of the built environment. Treat the first two as 'limited access' facilities, where board is only possible at stops. Lacking Cube, however, it should be possible using ESRI Network Analyst.
