Development of an Integrated Multimodal Simulation System for the I-270 Commuting Corridor

The primary objective of this study is to develop an integrated multimodal simulation system for the I-270 corridor, which includes the I-270 freeway and its parallel routes, the subway and rail lines from the city, Germantown, all way to the I-495 Capital Beltway. The proposed system shall serve as an effective tool for responsible transportation agencies to address the following vital issues: The impact of HOT and other control strategies on the distribution of traffic patterns along the I270 freeway and among all available commuting transportation modes; The cost-benefit of any proposed new supply-side congestion mitigation plan, such as additional travel lanes, light rail line, bus rapid transit (BRT), and their impacts on the distribution of daily travel demand among all transportation models; The impact of any major land-use development on the spatial and temporal distribution of traffic congestion patterns; and The optimal distribution of commuting trips between all available modes during major incidents where one or more modes suffer a substantial capacity reduction.
