The Illinois Department of Transportation (IDOT) owns or maintains more than 8,000 bridges over waterways throughout the state. IDOT’s Central Bureau of Bridges and Structures (aka the Bridge Office) employs state-of-the art tools to help ensure that bridge and culvert waterway openings are adequately designed to provide safe crossing.Read More
Obtaining an accurate picture of road conditions at any given time is a great benefit to motorists and road construction and maintenance crews. Currently, highway maintainers use weather forecast sites and road weather information system (RWIS) data to support winter maintenance decisions. Combining weather forecast data with pavement models creates a new dataset that can be highly useful to IDOT, as well as to municipal and county agencies.
Approximately 27% of all intersection crashes in the United States are associated with left turns, with more than two-thirds of those occurring at signalized intersections. Various traffic signal control strategies have been implemented to balance concerns about both the efficiency and safety of left-turning traffic. Read More
Crack sealing is a cost-effective, preventive maintenance method that helps extend the service life of pavements by preventing liquid and solid materials from penetrating the pavement system. Depending on the temperature of the sealing material at the time it is applied, sealants are classified as either “cold-pour” or “hot-pour.” When properly selected and installed, sealants have the ability to extend the service life of pavements from three to five years.Read More
ICT researchers strive to facilitate the development and timely implementation of cost-effective technologies that improve safety, durability, and reliability; reduce congestion and environmental impact; optimize the life and use of the transportation infrastructure; and maximize the return on taxpayer dollars.Read More
