Considering the significant benefits that transit service could bring in contributing to the overall project goals in reducing congestion, enhancing system performance, and improving environmental, economic and social concerns, this project aims to provide a standard approach that enables the incorporation of transit service goals and benefit considerations into express lane (EL) programs. A planning framework is developed with five major components, including project initiation, market assessment, ridership forecast, alternative evaluation, service design and implementation. A ridership forecasting methodology is also proposed and demonstrated through a case study of the 95 Express service. The approach utilizes both STOPS and TBEST, combining their strengths in different aspects. STOPS is able to consider the competitiveness between highway and transit modes, while TBEST provides detailed considerations at stop and route level that enables detailed scenario analysis. The case study demonstrates that the proposed approach serves the purpose well on estimating ridership for express buses from two main perspectives: (1) it is able to estimate the mode shift due to the introduction of express bus services in terms of how many new transit users are being attracted; and (2) it provides a sufficient level of detail to support scenario analysis that can facilitate the decision-making in transit service planning, based on the capital and operating costs involved with alternative service plans. |
