This study explored the feasibility and acceptability of using stay in-place fiberglass reinforced plastic (FRP) jackets and underwater steel reinforced grout for timely bridge piling repairs in Minnesota without dewatering. One of the goals of the project was to determine the current state of practice to this corrosion repair and inspection by researching other projects […]
Artificial intelligence (AI) has revolutionized various areas in departments of transportation (DOTs), such as traffic management and optimization. Through predictive analytics and real-time data processing, AI systems show promise in alleviating congestion, reducing travel times, and enhancing overall safety by alerting drivers to potential hazards. AI-driven simulations are also used for testing and improving transportation […]
Roundabout implementation in the United States has increased in the last decade, and practitioners have learned lessons in successfully applying roundabouts in various land use and transportation environments and contexts. The TRB National Cooperative Highway Research Program’s NCHRP Research Report 1043: Guide for Roundabouts provides information and guidance on all aspects of roundabouts. Read the full guide […]
Hazard perception (HP) is one of the few driving skills proven to reduce traffic accidents through training and testing. The driver licensing process in some countries includes assessing individuals through videos demonstrating hazards and measuring their reactions. Testing HP using a driving simulator has been shown to better approximate real-world driving and, therefore, be more […]
The United States faces a road safety crisis: the fatal crash rate per mile traveled has been climbing for the past decade, and crashes involving vulnerable road users—pedestrians, bicyclists, and others who share the roads with motor vehicles—have grown the fastest. Furthermore, motor vehicle death rates in the United States are three to four times […]
Electric buses are on the way to the University of Alabama campus in Tuscaloosa. Officials say this will make UA one of the first schools in the SEC to adopt a ‘zero-emissions’ public transportation system. A total of eight electric buses will be on campus by this summer. The cost will be $10 million. Most […]
The biggest names in global industry — NASA, Boeing, Lockheed Martin, Mercedes-Benz, Hyundai, Airbus, Toyota and more — call Alabama home. These companies, paired with world-class researchers at Alabama universities, are driving innovations in mobility technologies and positioning the state as a leader in the next generation of transportation. “Alabama is driving the future of mobility across land, air, sea and space,” said Ellen […]
TRB’s Behavioral Traffic Safety Cooperative Research Program (BTSCRP) has released its annual report. BTSCRP provides practical, ready-to-implement solutions to save lives, prevent injuries, and reduce the costs of road traffic crashes associated with unsafe behaviors. The BTSCRP 2024 Annual Report highlights current and pending projects, sponsors, publications, and other details about the program. Read the full report […]
Decarbonisation of road transport was until recently considered the most challenging part of the climate agenda. Still the ascent of electric vehicles is making significant advances possible while, at the same time, opening several new complex conundrums: integration of power and transport systems, establishing supply chains of needed materials and conversion of existing industries to […]
ALDOT continues to make steady progress on the new Intracoastal Waterway Bridge in Gulf Shores, a $52 million project designed to ease traffic congestion and improve safety in the area. Alongside the bridge, a $30 million connector project to tie into SR-161, formerly designated as the Foley Beach Express, is also underway. Both projects are […]
