The Lassen County Transportation Commission hired the team of Traffic Works and Green DOT Transportation Solutions to prepare a park & ride study to address the regional and local coordinated transportation needs. Lassen County has at least 4 ad-hoc park & ride facilities used by more than 200 vehicles a day. These facilities are un-improved for the most part and cause major safety and maintenance issues. This project was a concerted effort to identify appropriate locations for the park & rides based on the existing and potential future users of the facilities. We worked with the major employers in the area, land use authorities, Caltrans, and a large stakeholder group to identify existing conditions and programs, users, and future improvements and site locations. The final report identified and recommends two formal park & ride facilities. These recommendations were accompanied by preliminary planning and implementation plans.
