2018 Solano Travel Safety Plan *ADOPTED May 2018*

Download the 2018 Solano Travel Safety Plan, which was adopted by the STA Board at their May 9, 2018 meeting. Prior to that, it was released for 30-day public comment by the STA Board of Directors on February 14, 2018.

As an ongoing effort to identify and address safety needs across the county, STA prepared Travel Safety Plans in 1998, 2005, and 2016. The 2016 Safety Plan departs from the methodology used in the previous plans, primarily as a result of the lack of recent and comprehensive traffic volume count data needed to determine collision rates. Instead, the 2016 Solano Travel Safety Plan used input from local jurisdictions to identify locations with safety issues and recommended improvements. Many of those project recommendations were made in response to recent collisions. This methodology helped each city identify its own safety locations, but did not prioritize safety improvements in the format necessary for Highway Safety Improvement Program (HSIP) funding.

This 2018 Solano Travel Safety Plan, funded by the Caltrans-created Systemic Safety Analysis Report Program (SSARP) grant, expands the 2016 project list with projects identified through a data-driven analysis.  The 2018 Travel Safety Plan is a systemic analysis of trends and patterns from the crash record that allows for system-wide identification of improvements to address observed and potential safety issues. The resulting project list and analysis will assist local agencies in prioritizing safety improvements that will qualify for Highway Safety Improvement Plan (HSIP) funding. The 2018 Travel Safety Plan will also act as a policy and guidance document to provide ongoing assistance to STA and staff from all of the Solano County jurisdictions in continuing to identify needed safety improvements as the roadway network and travel patterns continue to evolve.

The STA accepted comments December 11, 2015 through January 10, 2016. 

Traffic collisions and injuries are once again on the rise in Solano County, after years of a downward trend. The Solano Travel Safety Plan (Safety Plan) has been updated by the STA and staff from member agencies (Benicia, Dixon, Fairfield, Rio Vista, Suisun City, Vacaville, Vallejo, and the County of Solano) to try and reverse this trend.

The plan identifies locations where local agencies may implement projects and/or redesign streets to reduce the frequency and severity of collisions on local streets and roads throughout Solano County. The Safety Plan will help guide the STA when prioritizing funding for plans, programs, and projects in the goal to eliminate fatalities and severe injuries on our roadways.

The Safety Plan documents work completed since the last Solano Travel Safety Plan was updated in 2005 (see below), and sets new priorities to actively secure funding to implement new safety projects.
