Implementation of Statistical Analysis Makes IDOT Traffic Counts More Efficient

Published November 19, 2015

Last year, ICT completed a project on behalf of the Illinois Department of Transportation (IDOT) to evaluate the feasibility of decreasing the time frame for traffic counts. IDOT had been seeking to extend an existing waiver from the Federal Highway Administration (FHWA) on Highway Performance Monitoring System (HPMS) sections to conduct 24-hour traffic counts instead of the 48-hour counts required by FHWA. These counts are used to determine the average annual daily traffic (AADT) for roads.

A project completed by ICT in 2013 on behalf of the Illinois Department of Transportation (IDOT) is still making an impact in the pavement world. The project, “Best Practices for Implementation of Tack Coat” (R27-100), was published as two reports: Part 1 (laboratory study) and Part 2 (field study). Read More

ICT Investigates Nondestructive Methods to Evaluate Pavement Condition and Development of Improved Overlay Thickness Design Alternatives for IDOT

Published October 12, 2015

Local and state highway agencies dedicate a significant portion of their annual pavement management and rehabilitation budgets for assessing the condition of in-service pavements. To aid agencies in selecting an adequate, effective, and economical rehabilitation strategy, an accurate means for evaluating the functional and structural deficiencies of an existing pavement is necessary.
