Impacts of Coastal Cities' Physical Geography on Traffic Related Congestion and Pollution

How does the natural geography and the urban fabric of a city impact urban sprawl, increased single occupancy vehicle ownership, and a lack of public mobility infrastructure? 

In a new paper for Environment and Planning B, Albert Saiz and Luyao Wang utilize the Greater Boston area to demonstrate how natural barriers intensify automotive traffic congestion, system wide trip delays, and reduce the capacity to diffuse commuter flows through a mobility system.
