This paper compares the potential benefits and impacts of two types of congestion pricing: oad- or cordon-based, and parking-based, that the San Francisco County Transportation Authority studied as a part of the Mobility, Access, and Pricing Study. The study is evaluating comprehensive pricing and mobility-enhancing packages to improve access and offer more sustainable travel choices to and within San Francisco. The Study Team evaluated the cordon and parking congestion charges using the SF-CHAMP regional travel demand model (also known as RPM-9). This paper discusses the current representation of parking in SF-CHAMP and its limitations, and then summarizes the development of an improved parking representation including additional data needs.

2. Mobility, Access and Pricing Study Goals
‣ Improve mobility by reducing travel times and increasing
system efficiency for both motorists and transit
passengers
‣ Increase accessibility by providing improved and more
reliable transportation options
‣ Enhance overall quality-of-life by reducing traffic and
tailpipe emissions to improve safety and health
‣ Promote the city’s economic vitality by improving
multimodal access to facilitate future growth and
enhance regional competitiveness

21. Conclusions
‣Could be effective at reducing VMT and peak
auto congestion
‣BUT trip suppression is more of a concern
‣Some of the benefits are likely to be eroded by
increased through trips in the Focus Area
‣Challenging to serve the new transit demand with
available revenue
SAN FRANCISCO COUNTY TRANSPORTATION AUTHORITY 17
22. Caveats & Future Work
‣This was an exploratory analysis
‣Parking data needs
‣ Payment ranges and subsidy levels for existing
parking inventory
‣ Reserved vs unreserved
‣Coordination with SFpark
