Pavement Safety Performance (PSP) Data Analysis Program
This project will integrate pavement performance databases with highway safety information systems and analyze the data to develop crash modification factors and pavement management strategies that include safety.
- Prove that pavement surface characteristics are the most important factors affecting the number of fatal and disabling injury crashes.
- Prove that rigid pavements have lower crash rates than flexible pavements.
- Demonstrate that the concrete mixture proportions associated with higher strength concretes have lower friction numbers and that an intermediate strength provides the optimum performance in terms of safety and distress.
- Demonstrate that recycled asphalt concrete pavements have lower friction numbers.
- Prove that the current state-of-the-art method to develop Crash Modification Factors (Empirical Bayes) yield inaccurate numbers for pavements.
