FN City of SantaAna l First Street Multimodal Corridor <br /> Technical Memorandum <br /> The section east of Garfield (between Garfield Street and Standard Avenue)experienced the <br /> highest percentage of daily traffic traveling at a speed greater than 40mph at 8,687 vehicles per <br /> day or 26%of the daily traffic on the segment. <br /> Why is this important? Figure 7 illustrates the probability of fatality in a pedestrian-vehicle crash based <br /> on vehicle speeds. The curves represent different age ranges. According to data collected by the <br /> Automobile Club of America (AAA)and illustrated by ProPublica in an interactive graph, a 70-year-old <br /> person has a 70% chance of being killed by a vehicle traveling at 40mph. While young adults have a <br /> higher chance of surviving a crash at 40mph, the probability of fatality increases exponentially as <br /> speeds increase with the chance of any pedestrian surviving being struck by a vehicle moving at <br /> 60mph of less than 10%. Identifying solutions to reduce the traffic speeds of these high-speed <br /> vehicles will significantly improve safety and reduce both severe injury crashes and fatalities. <br /> Figure 7.
