Countywide Systemic Non-signalized Intersection Improvements

This project proposes safety improvements at ten two-way stop controlled intersections within unincorporated Fresno County.  The improvements include installing multiple low cost improvements to improve safety, compliance with stop controls, and improve intersection awareness, such as:

   • Add lighting, larger signage, and improve pavement markings at all 10 intersections;

   • Install transverse rumble strips at all but one intersection where they already exist;

   • Make adjustments to improve sight distance at 10 of the intersections;

   • Install left turn lanes at 2 of the intersections;

In total, there will be 206 improvements made at the ten intersections. 

The intersections were identified through an evaluation of collision data within the unincorporated Fresno County occurring over a five-year period; between 2017 and 2022 , and through the County’s Local Road Safety Plan (LRSP).  Each crash in the county was weighted based on the Equivalent Property Damage Only (EPDO) score. One hundred most highly scored intersections in the county were screened to determine those that a systemic treatment could be applied to. 

The ten intersections included in this application experienced a total of 123 crashes, 11 of which were fatal and 79 resulted in injuries, 20 of which were severe.  32 occurred at intersections where no street lights were present.  All of the fatal crashes were broadside collisions, as well as 88% of the total crashes.  The proposed systemic treatments would increase drivers’ awareness of intersections and compliance with stop-control and are expected to reduce these types of collisions.

On September 17, the Department submitted an application to the Highway Safety Improvement Program (HSIP) Cycle 12 requesting $4,295,985 for the project, which is 85% of the total estimated project cost of $5,054,100.  The County submitted an application for similar improvements at 44 countywide intersections in HSIP Cycle 11 but was unsuccessful.  Using that list of intersections and the County’s LRSP as a guide, the 10 intersections selected for this application were identified as the ones most likely to benefit from the chosen safety improvements (see location map below).  These intersections will then be used as examples for future intersection improvements, as the County has innumerable intersections that are in need of similar treatments.
