The Impact of Transit-Oriented Development Scenarios on Transportation in Maryland

摘要

This paper aims to find whether all transit-oriented development (TOD) can reduce travel distance and vehicle travels while increasing transit ridership, and which has a greater impact on transportation focus on housing policy or job location. We compare the impact of different TOD scenarios and measure the elasticity of travel demand as a result of the household or (and) employment growth reallocating into transit areas. We obtain the results using a validated transportation demand model (MSTM) for Maryland and future growth in 2030.The results suggest that TOD is effective in increasing transit mode share and decreasing vehicle miles travelled; but only some can shorten trip distance. We find (1) relocating employment can increase transit mode share more than relocating households, and (2) relocating employment increases total average trip length, while relocating households alone tends to decrease trip length.
