Abstract

In trying to develop a more data-driven approach to road safety, many cities have created their own version of a high-injury network analysis. The results typically reveal that a disproportionate number of road fatalities are concentrated on a relatively small fraction of streets. Despite the usefulness of the high-injury network thinking, the lack of a consistent methodology across different cities keeps us from being able to compare different cities and from identifying trends. The proposed project seeks to develop a generalizable, standardized approach to high-injury network analysis that leverages existing data sources in a way that can similarly applied across different cities. After developing the approach, we will apply it to the principal city within each of the 100 largest metropolitan areas in the United States, thereby offering a broad, comparative perspective of what traffic safety. Through this analysis, we explore the specific street and network design features that contributes to urban road fatalities. By standardizing the approach to defining high-injury networks, this research aims to enable more consistent safety analyses, facilitate more widespread adoption, and promote evidence-based strategies to enhancing road safety.
