Santa Ana Safe Mobility plan I Revised Scope of Work City of Santa Ana, CA we have identified common crash types, we will review a sample of collision report narratives to more fully understand the nature of each collision type. Of particular interest in this review will be the role of transit access in the pedestrian- involved collisions. 4.2 Risk Analysis The risk analysis will allow for the identification of risk factors that contribute to crashes involving people walling and bicycling in Santa Ana. We will utilize industry standard walling and bicycle crash types, such as those identified in I°Iow to Develop a Pedestrian Safety Action Plan (FHWA), based on the available data, and will identify the relative prevalence of collisions and types based on the roadway or intersection context. This "risk based" approach is particularly important due to the somewhat random distribution of crashes. For example, a history of five pedestrian involved collisions at a particular location is not necessarily predictive of future collision types at that location, due to the small sample from which conclusions are being drawn. Instead, it is critical to increase the sample size by developing a typology of intersections and corridors and comparing trends in collision types by location type. While certain intersections or corridors may be unique in their configuration (e.g., a alcewed intersection), there is also a predictability of conditions throughout the city, because land use and transportation development typically follow adopted city and state guidelines. An example outcome may be that larger arterial intersections have a prevalence of collisions involving a left - turning motorist and a pedestrian in the crosswalk as a result of drivers having the difficult task of looking for a gap in multiple lanes of oncoming traffic. Fewer collisions of this type may be evident at intersections with fewer lanes, a left turn bay, or a protected left turn signal phase. We will review the available data and conduct additional data assembly from available GIS layers and may create new layers based on aerial imagery or field reviews to allow for sufficient detail in the dataset to create categories reflective of the differing conditions in the transportation network that impact walking and bicycling safety in Santa Ana. This informative and user friendly map, which we Finally, this systemic analysis will look at collisions developed for the City of Rochester, MN identifies the location and frequency of all crashes, with unique citywide for all modes that have primary collision symbols for bicycle and pedestrian crashes, drawing factors known to increase the probability of a severe attention to high crash corridors and intersection types. or fatal collision with vulnerable roadway users -- notably, speeding, distraction, or redlight running. Generally speaking, the majority of collisions involving pedestrians identify failure to yield as the primary collision factor, and sometimes secondary collision factors such as these are missing. An analysis of motor vehicle involved only collisions will help inform the risk analysis, calling to attention locations where these high risk factors are at play.
