Analysis of Bicycle-Related and Pedestrian-Related Roadway Crashes

Source: Colorado Department of Transportation

The premise of this study is that crashes involving bicyclists and pedestrians are similar in characteristics, including type and cause. Using available data and existing analysis tools, the study conducted a corridor-specific approach along state highways within local and/or county jurisdictional boundaries to identify potential trends based on patterns in crash types and causes. For instance, do the majority of pedestrian crashes along a corridor occur at mid-block locations; at or near intersections that involve a pedestrian hit by a turning vehicle; or involve a pedestrian hit from behind while walking with traffic along a roadway shoulder (paved or unpaved) and not on a sidewalk? Do most bicycle crashes involve a motorist overtaking a bicyclist, a motorist turning or merging into the path of a bicyclist, or a bicyclist turning or merging into the path of a motorist? By identifying common causal factors of bicycle and pedestrian crashes, this study should help planning and design efforts to provide safer intersections and corridors for use by pedestrians and bicyclists. The study developed recommendations to improve statewide, county and local data recording of bicycle and pedestrian crash factors.
