In this study, we address the problem of simultaneously selecting the location of the DWPT facilities and designing battery sizes of electric buses for a DWPT electric bus system.Posted: Oct 29, 2018 A research paper on safety at highway rail grade crossings written by two NDSU students was recently featured on the cover of the journal Safety.Posted: Oct 29, 2018 In this issue you can find information on graduate school news and recent/upcoming happenings in the transportation field. This issue also includes a variety of upcoming transportation conferences, workshops, and webinars you may be interested in.Posted: Oct 24, 2018 "Application of Machine Learning Method to Evaluate Road Roughness from Connected Vehicles" was recently published in the Journal of Transportation Engineering, Part B: Pavements. UGPTI's Raj Bridgelall was a co-author of the article. Posted: Oct 24, 2018 NDSU researcher Kimberly Vachal recently presented an assessment of North Dakota's 24/7 Sobriety Program at the 62nd Annual Scientific Conference of the Association for the Advancement of Automotive Medicine in Nashville, TN.Posted: Oct 23, 2018 Structurally deficient bridges in the United States may be replaced with a viable alternative made with Cross Laminated Timber (CLT). The ultimate goal of this project is to improve bridge sustainability and performance using CLT products.
