This is a continuation of a project to model and evaluate the opportunities to reduce greenhouse gas emissions by expanding express commuter bus services in the Greater Boston area. The previous project developed a model to estimate the emissions associated with the current mode split of commuters traveling by car, carpool, walk, bike, or four transit modes by walk or drive access. The model was then used to estimate the effect of a new commuter bus service on operating costs, mode share, and greenhouse gas emissions. The purpose of this project is to analyze the performance of existing commuter bus services that are included in the travel demand model that is maintained by the Central Transportation Planning Staff (CTPS) and new commuter bus service that has since been introduced. This project includes specific attention on one of the corridors identified as a �high-efficiency corridor�: Framingham-Boston. It also provides the opportunity to explore whether there are additional efficiencies that could be attained through service design adjustments. Specifically, this project involves refining the accuracy of the model, analyzing the potential impact of running buses in dedicated lanes or highway shoulders, and consideration of specific details of commuter bus stop location that affect the attractiveness for access by walking or driving. |
