Transportation Safety Analysis is a critical component of transportation engineering. Implementing the correct method of statistical analysis is vital. Our team understands the limitations of Crash Frequency and Crash Rate; therefore, we utilize state-of-the-art techniques that account for Regression to the Mean (RTM) bias.
We have implemented Substantive Safety Analysis in numerous engineering projects, building more than 100 location-specific Safety Performance Functions (SPFs) to perform systematic transportation engineering analyses with unmatched precision.
In the process of helping government entities implement systematic safety analysis, our team developed the SPF Tool (spftool.com). It is a cloud-based application designed to incorporate the most advanced statistical techniques into a user-friendly, minimalist interface.
