Project Information
Final Technical Report

The primary goal of this project is to provide a better understanding of a driver’s passing behavior and model their decision-making on two-lane rural highways under different geometric configurations.  This project will specifically examine passing behavior on horizontal curves on two-lane rural highways and explore how the different degrees of curvature influence driver behavior.  The outcome of the project will provide state DOTs with guidelines that allow them to improve the safety and efficiency of traffic operations along this particular type of highway setting.
