Improving the Effectiveness of Smart Work Zone Technologies

Published January 23, 2017

A recently completed project sponsored by IDOT and conducted by ICT investigated the effectiveness of sensor network systems for detecting traffic jams or stopped traffic, estimating travel times and delays for motorists, and estimating speed of vehicles in and approaching roadway work zones.Read More

IDOT Develops Safety Project Webinar Series Based on Research Conducted by ICT

Published January 23, 2017

Findings from three safety-related research projects conducted by the Illinois Center for Transportation (ICT) on behalf of the Illinois Department of Transportation (IDOT) have been implemented as a technology deployment webinar series geared to IDOT and local agency staff, as well as consultants, designers, and contractors who are involved with roadway construction and maintenance in Illinois.

The webinars were recorded and are available for viewing online (links provided below).

Guidelines Developed for Low-Water Crossings on Low-Volume Rural Roads in Illinois

Published January 23, 2017

Low-water crossings (LWCs) are roads over small creeks and streams and are designed to be overtopped by water during a high flow event. These LWCs are located on low-volume roads with fewer than 25 vehicles per day—typically access roads to farm fields. For these crossings, it is not necessary or feasible for the local highway department to install a bridge. Therefore, a LWC can be designed and constructed to provide a safe, economical, and environmentally friendly pathway to endure overtopping events.

Guidelines Developed for Hot-Poured Crack Sealant Treatments

Published November 21, 2016

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

Modified Right‐Turn Lane Design Improves Road Safety and Operations

Published October 17, 2016

Exclusive right-turn lanes are usually associated with improved safety because they tend to separate the conflicts between turning vehicles and through traffic. However, right-turn lanes on state routes are designed in a way that accommodates large vehicles, such as semi-tractor trailer trucks. At these intersections, raised channelized islands with exclusive right-turn lanes are commonly used, and there is a large turning radii.Read More
