This research project has a focus on the load and resistance factored rating (LRFR) live-load factors for load rating bridges in Illinois. The study’s objectives were to examine the adequacy of available Illinois ...

Illinois StreamStats (ILSS) is a Web-based application for computing selected basin characteristics and flood-peak quantiles based on the most recently (2010) published (Soong et al., 2004) regional flood-frequency equations ...

Pavement management systems have proven to be an effective tool for management of large state and metropolitan pavement networks. Although smaller agencies no doubt have similar operational and organizational needs and ...

In this project, Illinois-specific design procedures were developed for drilled shafts founded in weak shale. In addition, recommendations for field and laboratory testing to characterize the in situ condition of weak ...

Currently, the Illinois Department of Transportation (IDOT) is one of the few state transportation agencies that require warning lights on nighttime work zone channelization devices, such as drums and barricades. The ...

This project evaluates the effectiveness of sensor network systems for work zone traffic estimation. The comparative analysis is performed on a work zone modeled in microsimulation and calibrated with field data from two ...

Moving lane closures are an increasingly utilized and potentially hazardous traffic control procedure for highway maintenance and operations activities. To improve the safety of moving lane closures for workers and motorists, ...

This report summarizes the tasks and findings of the ICT Project R27-132 Incorporating National Environmental Policy Act (NEPA) into IDOT and Metropolitan Planning Organization (MPO) planning processes, which is aimed at ...

Integral abutment bridges (IABs) have become of interest due to their decreased construction and maintenance costs in comparison to conventional jointed bridges. Most prior IAB research was related to substructure behavior, ...

This project investigated the installation and performance of snowplowable reflective pavement markers (SRPMs) to determine optimum pavement marker solutions and policies for roadways in Illinois. The research evaluated ...
