Pedestrian Crash Risk Assessment Study

A systemic safety analysis was commissioned by ODOT to identify risk for pedestrian crashes on intersections and segments (arterials and collectors) using ODOT District 8 as a pilot and including Greene and Warren Counties in our Region.  Miami and Montgomery Counties in District 7 were later added following discussions with ODOT’s safety program staff.

Using a variety of data impacting pedestrian crashes, risk factors were used to identify the “priority network” — locations where conditions exist for pedestrian crashes to occur on arterial and collector facilities for both intersections and segments.  Several risk factors were considered including roadway characteristics (e.g. speed and traffic volume) as well as area characteristics such as presence of libraries and zero car households.  More than 400 attributes were tested for consideration and the final analysis produced 15 risk factors that were used to identify the priority network.  The analysis focused on the transportation urbanized area since the majority of crashes occur there.  Locations were then plotted on a map based on an overrepresentation of risk factors — the higher the number of risk factors, the higher the risk for pedestrian crashes.

The priority network can be viewed on this map, the underlying data is available upon request.
