The project’s results will help enhance the Advanced Traveler Information System by improving the identification of weather conditions using existing WYDOT infrastructure.
Research at the University of Utah is providing a scalable, privacy-preserving solution for improving culvert condition prediction. This method will enable transportation agencies to make more data-driven, proactive maintenance decisions.
A new method for improving measurements of soil shear stress, erosion, and scour will help engineers design bridges that are more resilient and longer-lasting.
Recent research conducted at South Dakota State University shows that E. coli contamination of stormwater runoff was reduced by an average of more than 44%, and phosphate levels were also significantly reduced in a pilot stormwater filtration that used steel chips and steel slag as a filtration media.
Research at South Dakota State University to better understand stream flows will lead to improved designs for bridges, culverts, and other infrastructure elements that are subject to erosion and scour.
Researchers at the University of Utah have developed technology that can potentially conduct multi-lane roadway ice/snow coverage estimation, which is superior to the state-of-the-art single-spot measurements.
Researchers at the University of Utah are exploring local resonances, a form of ultrasonic vibration, to detect defects and thermal stress in railroad rails.
Researchers at Colorado State University developed and applied a methodology for performing a complete structural analysis of transportation infrastructure elements, moving from digital images, acquired from either hand-held cameras or uncrewed aircraft systems, through several image processing schemes into a finite element analysis of representative structures.
Researchers at Utah State University studied the performance of concrete panels with embedded inductive charging systems in early near full-scale testing to learn how the panels performed under thermal stress from the charging system and load stresses from traffic.
Research at Colorado State University is a step toward improving models for simulating and representing the threats of natural hazards such as floods, landslides, and debris flows on transportation infrastructure.
With the increasing adoption of electric vehicles (EVs), particularly in rapidly growing regions like metropolitan areas, efficient deployment of charging infrastructure is critical to avoid overloading the power grid and to meet the charging needs of EV users. Researchers at the University of Utah developed a framework capable of modeling the spatiotemporal distribution of public charging demand and provide practical support for future public charger installations.
Drivers will be less likely to experience bumps at the ends of bridges thanks to research at the University of Utah into the settlement and heaving of soils used in bridge embankments. Laboratory tests were performed on compacted specimens of 10 embankment materials specified by the Utah Department of Transportation using both standard-size and large-scale equipment.
Researchers at the University of Colorado Denver developed a low-cost, scalable solution for real-time monitoring of roadway conditions, reducing traditional inspection costs from $429 per mile to near zero by utilizing GPS and smartphone sensors in vehicles.
Research at the University of Colorado Denver found that paratransit trips experience more inefficient travel times than an equivalent car trip. Paratransit is assumed to be an effective door-to-door service that enables people with disabilities to travel easily. However, when using the standard benchmark of car travel as a comparison, the research shows that paratransit often fails those with disabilities.
Wes Marshall, CTIPS director for the University of Colorado Denver, continues to garner press attention for his 2024 book, Killed by a Traffic Engineer: Shattering the Delusion that Science Underlies our Transportation System. Marshall was recently interviewed by Flora Lichtman for Science Friday, a program that airs on more than 500 public radio stations across the United States. Marshall’s interview aired April 18.
The University of North Dakota steel bridge team recently qualified for the Student Steel Bridge Competition National Finals to be held May 30-31 at Iowa State University in Ames. The team is advised by Sattar Dorafshan, CTIPS director for UND.
Arman Malekloo, a Ph.D. student at the University of Utah, has been named a 2025 Lifesavers Traffic Safety Scholar, one of only 29 students across the United States selected through a competitive application process. The honor gave him the opportunity to attend the Lifesavers Conference on Roadway Safety in Long Beach, California.
New high-resolution computational fluid dynamics simulations are providing insights into the tremendous forces that cause semi-trucks and other high-profile vehicles to topple during high-wind events.
Research at Colorado State University shows that action-conveying and emotionally motivated signs are more effective at influencing pedestrian safety and decision-making at railroad crossings.
Researchers at North Dakota State University improved commercial vehicle weight monitoring accuracy by more than 90% by combining traditional weigh-in-motion systems with machine learning techniques and advanced sensor data to integrate information on temperature fluctuations, pavement surface conditions, and vehicle dynamics.
Researchers at Colorado State University have developed an automated pothole detection tool, which combines visible and thermal images to reliably identify potholes under various conditions, particularly in regions with challenging weather.
Researchers at Colorado State University studied various approaches to eco-driving in connected autonomous vehicles to learn how best to evaluate the methods for energy economy. Eco-driving is a strategy designed to reduce fuel consumption by minimizing accelerations and unnecessary braking events.
Research at South Dakota State University shows that plastic from used water bottles can be turned into microfibers and used to improve the performance of asphalt.
Research at Utah State University suggests that travelers who adjust their travel behavior in response to area-wide pollution do so as a "risk averse" reaction rather than for "altruistic" reasons.
