Survey Results

In Spring 2017, Caltrans conducted an online survey to collect public input on bicycling needs, issues, and recommendations for the State-owned transportation network across the Bay Area. A total of 4,721 people visited the survey and placed a total of 20,157 “pins” on the map. The survey data will help inform the District 4 Bicycle Plan and is available for download under Documents and Links.

Caltrans Bike Plan

What is the Caltrans District 4 Bicycle Plan?

The District 4 Bicycle Plan is being developed within the framework of Toward an Active California, the California State Bicycle and Pedestrian Plan. This framework includes an overall vision, goals, objectives, and strategies that are intended to shape the statewide policy direction in California. The District 4 Bicycle Plan adopts this framework. The Caltrans District 4 Bicycle Plan is a visionary and comprehensive planning document that will result in a list of projects and strategies to improve safety and mobility for bicyclists on and across the State transportation network in District 4.


By 2040, people in California of all ages, abilities, and incomes can safely, conveniently, and comfortably walk and bicycle for their everyday transportation needs.


The goals for Toward an Active California were adopted from the multimodal California Transportation Plan (CTP), adopted in 2016, providing consistency with state transportation planning. Specific CTP/Toward an Active California goals include:

  • 1. Improve multimodal mobility and accessibility for all people
  • 2. Preserve the multimodal transportation system
  • 3. Support a vibrant economy
  • 4. Foster livable and healthy communities and promote social equity
  • 5. Improve public safety and security
  • 6. Practice environmental stewardship
  • Objectives

    Toward an Active California includes four objectives:
    • Safety – Reduce the number, rate, and severity of bicycle and pedestrian involved collisions
    • Mobility – Increase walking and bicycling in California
    • Preservation – Maintain a high quality active transportation system
    • Social Equity – Invest resources in communities that are most dependent on active transportation and transit

    Why is the Bicycle Plan important to the Bay Area?

    Caltrans updated its mission and goals on safety and sustainability and set a target to triple bicycling by 2020. With more than 700 miles of freeways and expressways and over 1500 miles of non-freeway State highways throughout District 4, Caltrans has an opportunity to help remove barriers to bicycling. Bicycle facilities that are safe, comfortable and convenient can help:

    • Improve public health and promote active lifestyles;
    • Create connections that allow people to bike to work, school, or transit; and
    • Reduce traffic congestion and greenhouse gas emissions.
    The Bicycle Plan will help guide decision makers and Caltrans staff in developing projects and programs to enhance bicycle safety and mobility throughout District 4. It will also be a valuable reference and informational source for Caltrans local partners and the general public.

    Get Involved

    To develop a Bicycle Plan that reflects the needs and priorities of Bay Area communities, Caltrans will seek input from a wide range of constituents, advocates and agency partners.
