Using Crash Data to Inform Roadway Safety Projects

Date: May 16, 2025

This post explores how Proxisco uses before-and-after crash analysis to guide engineering recommendations for high-risk locations. We discuss sample methodologies, significance testing, and how we communicate findings to agencies.

A Smarter Way to Number Simulation Scenarios in Transportation Studies

Date: May 20, 2025

Traditional methods of naming or tracking simulation runs rely on manually labeled combinations or arbitrary file names. But what if you want to automate everything, reproduce results months later, or scale to hundreds of configurations?

You need a deterministic and scalable indexing strategy. Continue reading to see how I approached and solved this porblem when I needed to do a full factorial simulation with several hundred scenarios that needed to be introduced to VISSIM.
