This research project uses ethnographic methods complemented with passenger surveys where one of the authors drove for Uber and Lyft in the Denver, Colorado, region to collect quantitative and qualitative data on ride-hailing. Posted: Jun 20, 2019 MPC researcher Junwon Seo discusses research to evaluate performance of various SCC mixtures for use in prestressed bridge girders.Posted: Jun 19, 2019 Nick Ferenchak, Wesley E. Marshall, and Bruce Janson
Both reactive and proactive safety analyses provide unique and important perspectives on traffic safety. If our goal is to enable more people to safely walk and bike as opposed to simply reducing crashes, then it is imperative to consider active transportation traffic safety proactively.Posted: Jun 17, 2019 This research will contribute to an ongoing effort to improve public safety by preventing and reducing severity of rural road crashes.Posted: Jun 13, 2019 NDSU's chapter for the Association of Transportation and Logistics recently elected officers for 2019-2020.Posted: Jun 13, 2019 This study focuses on understanding the relationship between the accuracy of an in-pavement strain-sensor based WIM system and its external contributors such as humidity, temperature, wander behavior and wind speed.Posted: Jun 10, 2019 Kam Ng, Dawit Mebrahtom, and Khaled Ksaibati
In this research, laboratory experiments on resilient modulus were performed to characterize the local crushed base materials in Wyoming. A comprehensive resilient modulus test program was completed.Posted: Jun 5, 2019 WYDOT implements the two-vehicle method to measure passing sight distances on Wyoming’s two-lane roads. The objective of this study is to provide two state-of-the-art prototypes of the two-vehicle method having advanced intelligent transportation system features to WYDOT.Posted: Jun 4, 2019 MPC researcher Ahmad Ghadban describes research for design, material selection, constructing, testing and application of FRC in South Dakota.Posted: Jun 3, 2019 The standards and protocols of CAV (connected-autonomous vehicles) technologies are currently in development, with limited number of tests and implementations. The installation of CAV hardware/software in traffic signals in Wyoming creates opportunities for developing methods and algorithms that would help the State's unique transportation challenges.Posted: May 31, 2019 Satpal Wadhwa an NDSU Ph.D. student in industrial and manufacturing engineering and a graduate research assistant with NDSU's Upper Great Plains Transportation Institute, received the 2019 Best Ag Transportation Paper Award at the Annual Transportation Research Forum in Washington D.C.
