Despite a downward trend in overall traffic fatalities, there has not been a corresponding decrease in non-motorist fatalities. While research has examined, in depth, the characteristics associated with fatal pedestrian crashes, little has been done to understand the contextual factors surrounding these incidents. For example, are pedestrian crashes more likely to be fatal in locations where housing is located across a major roadway from services, but too far away from a convenient and safe crossing location? Spatial analysis of crashes will allow the research team to gain additional insight into these crashes. The team will use several different datasets and analysis techniques to evaluate circumstantial evidence to create a more holistic picture of each crash. This will include cross referencing Strava data and ATSPM pedestrian actuations to better quantify volumes. Analysis methods will also include latent class cluster analysis to isolate significant factors that are not mutually exclusive but create an impact due to their presence together (e.g., lack of crossings and mix of land-uses, time of day, etc.). |
