Book Description
This project is to study the correlation between freeway traffic status and crash risks with the historical freeway ITS data and related crash data in Nevada. With the comprehensive review of previous research results, the Center for Advanced Transportation Education and Research at University of Nevada, Reno analyzed the interactive relationship between the freeway traffic status and crashes. The research developed a new method to correct the crash time that was not accurately documented in the crash report. A crash risk prediction model has been developed to estimate the influences of traffic status on collision risk. The impact of crash severity and crash type on after-crash traffic flows was also analyzed. The prediction models can be used to estimate the collision possibilities based on the real time ITS data. The models and analysis were based on the Nevada data so that they can be directly applied on Nevada freeways without additional calibration effort.
