Summary of Results from Cycle 4 and Recommended Preparations for the Next Call for Projects

During Caltrans’ HSIP Cycle 4 Call for local safety project applications and the corresponding project selection process, Caltrans found the HSIP Tool to be well received by local traffic professionals and the results confirmed that a data-driven approach maximized the effectiveness of the limited highway safety funding.   Although Caltrans only had enough federal funding for 45% of the total funding requested, the selected projects would generate 88% of the total expected benefits included in all of the applications.  In addition, applications with low-cost, systemic improvements had significantly higher Benefit vs. Cost ratios and consequently, a higher possibility to be selected for funding.  For more information on these results, some of the lessons learned during the call, and Caltrans recommendations for how local agencies can prepare for the next call for projects, view the links below:

Between Cycle 4 and Cycle 5, Caltrans contracted with UC Berkeley, SafeTREC and worked in conjunction with FHWA to expand the safety analysis elements of the existing HSIP Tool and to provide a more comprehensive guide for California’s local agencies working to improve the safety of their roadway network.  Caltrans made significant improvements to the HSIP guidelines, application, and safety analysis tools for HSIP Cycle 5 Call-for-Projects.  This projecet yield tangible safety results and moved California's roadways further "towards zero deaths."
