The performance of three Video Detection Systems (VDS), namely Autoscope, Iteris, and Peek, was evaluated at stop bar and advance locations, at an instrumented signalized intersection located in Rantoul, Illinois, ...

The Illinois Department of Transportation (IDOT) estimates pile lengths based on a static analysis method; however, the final length of the pile is determined with a dynamic formula based on the pile driving resistance exhibited ...

Reclaimed asphalt pavement (RAP) is the reprocessed hot-mix asphalt (HMA) pavement material containing asphalt and aggregates. A viable solution for deposing of large quantities of RAP is to incorporate them into base and ...

The goal of this project was to assist design engineers in developing more realistic construction schedules for a wide variety of IDOT projects. The research involved conducting in-depth interviews with subject matter ...

Project IHR-R39, titled “Validation of Design Concepts for Extended Life Hot Mix Asphalt Pavements (ELHMAP), was funded by the Illinois Department of Transportation (IDOT) to develop data in support of the philosophy ...

The fatigue characteristics of an HMA mixture are an integral element of the structural design of a pavement containing asphalt concrete. There are a number of models that have been developed to express the fatigue behavior ...

Two microwave-based systems for vehicle detection (by Wavetronix and MS SEDCO) were evaluated at stop bar and advance zones of a signalized intersection under three adverse weather conditions: (1) wind, (2) snow-covered ...

The performance of a microwave radar system for vehicle detection at a railroad grade crossing with quadrant gates was evaluated in adverse weather conditions: rain (light and torrential), snow (light and heavy), dense ...

Research efforts at the Illinois Center for Transportation (ICT) focused on evaluating new sustainable applications of Quarry By-products (QB) or QB mixed with other marginal, virgin, or recycled aggregate materials in ...

This report contains the results from several meetings of three different focus groups. The meetings were conducted as a part of the evaluation for the Pilot Study of Advisory On-Board Vehicle Warning Systems at Railroad ...
