A “conflict point” is a location at which traffic paths routinely cross, merge, or <br />diverge and are generally more prone to near-misses or collisions between vehicles <br />than other locations on the road network <br />Why: Historically, there have been a high number of vehicle collisions along the corridor. By <br />reducing the number of conflict points, the number of vehicles collisions should also be <br />reduced. <br />Table 1 shows the number of potential conflict points at an example intersection (Altamont and <br />Farm Hill) and an example mid-block segment (Farm Hill between Emerald Hill and Brandy Rock <br />Way), before and during the pilot. In both cases, the number of potential conflict points is <br />reduced with the pilot design. A similar reduction in conflict points happened throughout the <br />corridor. <br />Table 1 Number of Vehicle - Vehicle Conflict Points <br />Number of intersections conflict points Pre-Pilot During Pilot <br />Jefferson at Altamont Way 10 8 <br />Number of midblock conflict points <br />Farm Hill Boulevard between Emerald Hill and Brandy <br />Rock Way 12 6 <br />Source: Redwood City <br /> <br />Measurement: Reported collisions are being tracked to determine if there is a reduction in the <br />number of crashes along the corridor (Alameda de las Pulgas to Woodhill). <br />Outcome: The average number of crashes per month before the pilot was based on total <br />collisions during the five-year period from 2010 through 2014. Crash data is being monitored as <br />the pilot progresses; Table 2 includes data from September through November 2015. <br />Table 2 Monthly Average Number of Crashes <br />Pre-pilot During Pilot Absolute Change Percent Change <br />1.3 1 -0.3 -22% <br />Source: Redwood City Police Department Collision Reports (9/4/15 – 11/30/15) <br />Note: There were three reported collisions during this time period <br /> <br />Next Steps: (1) Given the relatively small sample size, continue to monitor the crash rate along <br />the corridor to determine if the downward trend continues, (2) In response to interest from the <br />8.A. - Page 14
