performance in the presence of variable road hazards. Road networks plagued by consistent weather or work zones affecting driving conditions are where VSL systems could improve safety. Depending on the road condition and objective of the VSL installation, the system could be advisory or regulatory. In...
Connected and automated vehicle (CAV) driving features can impact traffic safety in many aspects owing to their improved driving behavior. On the other hand, road geometric design elements are mainly based on human reactions and behavior, which might affect safety depending on road layout and the parties...
For decades, work zone traffic safety under adverse weather conditions has been a serious concern for drivers and transportation agencies. Natural hazards often cause disruptions on roads and bridges and work zones during the retrofitting process. Existing studies on work zone traffic safety with statistical...
Transportation access management is defined as systematic control of the design, spacing, operation, and locations of street connections, interchanges, driveways, and median openings on the roadway with the purpose of providing vehicle access while preserving the efficiency and safety of the entire transportation...
This project aims to using eye-tracking technology to optimize work zone safety. First, a systematic literature review was conducted to present the background of its application in construction safety. In total, 81 publications were screened from Web of Science (WoS), Scopus, and American Society of...
This study evaluates two versions of the new super diverging diamond interchange (Super DDI) design as a possible alternative to improve the performance of failing service interchanges in the Denver, Colorado, metro. Three interchanges, Interstate 225 and Mississippi Ave, Interstate 25 and 120th Ave...
Railroad accidents can cause economic harm that extends far beyond their own financial losses. As one of the most efficient modes of long-distance freight transportation, losses in line capacity and cargo due to accidents can disrupt the supply chain and lead to commodity shortages everywhere. Therefore...
This research seeks to develop an infrastructure safety support system by embedding V2I enabled sensor networks into the transportation infrastructure to provide autonomous vehicles and human drivers with inputs to improve their decision making when obvious decisions may not possible. A new car-following...
Despite similarities to the US in terms of transportation, land use, and culture, Australia kills 5.3 people per 100,000 population on the roads each year, as compared to the US rate of 12.4. Similar trends hold when accounting for distance driven and the number of registered cars. This paper seeks to...
Tribal communities recognize the need to improve roadway safety. A five-step methodology has been developed by the Wyoming Technology Transfer Center (WYT2/LTAP) to improve roadway safety on reservations. This methodology was initially implemented on the Wind River Indian Reservation (WRIR), which led...
