Page 10 <br /> <br />Midblock <br />High Incidence Midblock Collisions were analyzed over a three-year period. A three-year time frame is <br />used as a one-year analysis does not typically have enough collisions to identify patterns. A midblock <br />collision is defined as a collision that occurred greater than 200 feet from an intersection (or 250 feet if <br />it is a rear-end collision). There were six segments that had four or more midblock collisions (the four- <br />collision threshold was chosen to analyze locations that may have more than one collision per year <br />over the three-year period). Each segment was reviewed in detail to identify correctable patterns and <br />found the following: <br />Santa Rita Road (West Las Positas Boulevard to Old Santa Rita Road) <br />This segment was analyzed last year and a <br />pattern of collisions that involved eastbound <br />right-turning vehicles out of Stanford/Valley <br />Care north driveway hitting northbound <br />bicyclists in the marked crosswalk was <br />identified. In both collisions the driver was <br />looking left at oncoming traffic. One additional <br />bicycle collision occurred after the last report <br />involving an eastbound right-turning vehicle <br />The remaining two collisions involved <br />southbound vehicles. <br />We installed warning signage for northbound bicyclists/pedestrians to be cautious/make eye-contact <br />with driver before crossing driveway and restriped the crosswalk with high visibility ladder markings <br />(Countermeasures R22 and R35PB). No further collisions have occurred at this driveway since the <br />changes were made. <br />Dublin Canyon Road (Foothill Road to Canyon Creek Circle) <br />This segment was analyzed last year, and a <br />pattern of hit object collisions was identified (all <br />different objects). The only new collision since <br />last year was an eastbound vehicle that lost <br />control after swerving to avoid a shopping cart <br />in the roadway. <br /> <br />In past reports there was a pattern of collisions <br />at the westernmost curve. Additional and larger <br />signs were installed on this curve in 2016 <br />(Countermeasure R23). No collisions occurred <br />at that location in this report. <br /> <br />Pavement striping was evaluated last year and found to be adequate. This roadway was resurfaced in <br />September 2024. Additional striping/pavement markers were added through the western most curve <br />for extra notification of curves in the roadway (Countermeasure R28). Last year we also notified the
