A significant need exists for creating a model to estimate demand for intercity bus services, especially in rural areas. Many states and rural operators are unsure about the potential demand for rural intercity bus service, and many of the existing models are unreliable due to poor data (Fravel et al. 2011). To address this need, a Transit Cooperative Research Program (TCRP) project by Fravel et al. (2011) developed a sketch-planning guide that could be used by state transportation department program managers and both public and private rural intercity bus service providers to forecast demand for rural intercity bus services. The route-level modeling techniques used in this TCRP report provide a useful tool for estimating ridership on rural intercity routes, but it has some limitations. It does not account for through passengers that are using the service simply because it connects to others routes and it is not sensitive to changes in fares or frequency. The model proposed for this study will attempt to address these issues through the use of a regional network model. The intent of the Fravel et al. (2011) study was to develop a tool to help determine ridership on proposed feeder routes, rather than to construct a network model. A network model, however, would be a useful tool that would account for through passengers while estimating route-level demand and would show impacts of service changes and demand changes on the entire network. |
