The Need for Action

US-101 connects San Francisco, the Peninsula, and Silicon Valley. It is an important piece of the regional and local transportation network, serving as an essential link to support regional economic activity and access between communities. The purpose of the US-101 Mobility Action Plan (MAP) is to build on infrastructure and mobility improvements already planned and identify near-term policies, programs, and technological solutions that address unreliable access and mobility challenges on the corridor today. To do so, regional coordination across jurisdictional, county, and transit service area lines is needed. The MAP engaged with a broad set of decision makers to identify actions centered around non-infrastructure improvements to increase access, support the economy, and enable social mobility. These improvements will respond to five foundational problems:

US-101 is not moving as many people as it could


Travel time on US-101 is unpredictable


Worsening congestion reduces access to jobs


US-101 causes public health burdens and mobility constraints for nearby communities


Congestion, unpredictability, health, and limited transportation options present challenges for all — but low-income households, shift-based workers, and caregivers are more vulnerable

The US-101 Study Corridor
Mobility Action Plan Goals

The ideal US-101 corridor serves the region equitably
in service to three goals:


Offer reliable travel times 


Prioritize high-capacity mobility options, such as buses and carpools

Foster healthy and sustainable communities 

Project Timeline

Spring 2019

Study the US-101 corridor to better understand travel patterns, policies, demographics, and transportation services available today. Define the project need and set the Project Vision and Goals.

Summer 2019

Launch the 101-MAP website and community survey. Gather input at pop-up events and public meetings. Review best practices and case studies. Develop a list of Mobility Action Concepts.

Fall 2019

Share what we heard from the community. Develop and implement a concept refinement process linked to the project vision and goals. Conduct interviews with community leaders working with the area’s most vulnerable communities.

Winter 2019-Spring 2020

Assess the feasibility of each action. Define a list of Equity Actions to be implemented in tandem with the Mobility Actions.

Spring-Summer 2020

Finalize actions and define partner commitments for promoting and advancing the MAP actions.

The US-101 MAP was developed by a Project Management Team (PMT) comprised of:
