Demand Shifts and Their Effects on Traffic Congestion due to Toll Changes on Bridges in San Francisco Area

Abstract

In the San Francisco Bay Area, tolls are collected from seven state-owned bridges (as shown in Figure 1 below). Over the last decades, the toll schedule and price have been changed at multiple instances to administer the operation of bridges, to finance several bridge maintenance projects and to manage the level of congestion. This poster explore changes in traffic demand, as a consequence of toll changes and the price elasticity of demand; shifts by mode, time of day and locations; congestion mitigation impacts; an evaluation near-term long-term effects.
