Title:

Motorist-Cyclist Crash Data Needs in U.S. Communities

Accession Number:

Record Type:

Component

Abstract:

Over the past decade, understanding traffic safety using a data driven approach is becoming standard practice. While cycling is becoming popular in the US, safety remains a top concern, especially for engaging new riders. Although fatal cyclist crashes are recorded using standardized methods, there is a considerable variation in non-fatal crash data collection within and across communities. Non-fatal crash data is critically important for analyzing safety trends over time, prioritizing infrastructure improvements, and planning efforts. The lack of robust and standardized cyclist crash data precludes the analysis of trends across communities and limits the improvements and countermeasures that can be applied to increase cyclist safety. This paper compares non-fatal motorist-cyclist crash data across eight communities with respect to data availability, standardization, and quality. Findings reveal that while time variables such as hour, month, and day of crash were consistently coded across locations, vast differences existed with critical variables such as crash type and crash severity. These differences were observed both between communities as well as within communities from year-to-year. The non-standard data formats and differences within and between communities diminishes the ability to create safety performance functions and crash modification factors, which are critical metrics for safety analyses. This paper also provides suggestions to standardize non-fatal cyclist crash data in order to spotlight the data needs and bring much needed attention towards improving bicycle safety related data collection in the US.
