Research Highlights

Rapid Transportation Structure Evaluation Toolkit

Charles (C.J.) Riley
A previous NITC grant (#985 Dynamic Evaluation of Transportation Structures with iPod-Based Data Acquisition) supported education and research development at Oregon Tech in the area of mobile devices in sensor network applications to evaluate transportation structures via dynamic parameters like natural frequency and damping ratio. The goal of the previous grant was to determine the feasibility of using mobile devices in structural health monitoring applications and to build an educational… Read More

Improving Bicycle Crash Prediction for Urban Road Segments

Sirisha Kothuri Krista Nordback , Wesley Marshall
The 2010 Highway Safety Manual (HSM) provides methods for predicting the number of motor vehicle crashes on various roadway facilities (AASHTO, 2010). However, it includes only a simplistic method for predicting the number of bicycle-related crashes. The research team investigated the bicycle-specific crash data in eight potential study areas around the U.S.: Arlington, VA (city/county); Bellingham, WA (city); Boulder, CO (city); Denver, CO (city/county); Minneapolis and St. Paul, MN (cities);… Read More
