Ongoing Study Seeks to Improve Hot-Mix Asphalt Performance

Published April 1, 2017

In an ongoing effort to maximize performance of hot-mix asphalt (HMA) containing higher amounts of recycled materials, IDOT and ICT started a project called Construction and Performance Monitoring of Various Asphalt Mixes (R27-161) in 2014. A second interim report on the project was recently published, and work continues on the project. This effort is part of a larger goal of improving pavements made from recycled materials and enhancing the sustainability of asphalt pavement.Read More

Speed Harmonization: ICT Research Helps IDOT Improve Safety on Rural Roadways

Published April 1, 2017

Current geometric design of roadway elements is based primarily on the design speed. The design speed is used by roadway engineers to design appropriate safety elements such as vertical and horizontal curves, stopping sight distance, and guardrail needs. On rural highways, operating speed is often higher than the design speed, which may become problematic from a safety standpoint. In rural settings, there are also more free-flowing traffic conditions with limited enforcement opportunities. These circumstances often lead to increased crashes.Read More

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).
