Best Practices Adopted by IDOT

  • Two operational lanes in each direction by using shoulders;
  • Use ADT to predict queues and guide traffic control plans;
  • Dynamic Lane Merge System to decrease the time for vehicles to merge at a taper;
  • Type II barricades for safety driving conditions in WZ;
  • Change construction procedures to reduce frequency of lane closures;
  • Improved dynamic message signs for drivers;
  • Speed photo enforcement; and
  • Public safety programs.

Major Difficulties Encountered

  • Actual data is needed, including crash data, workers’ injury data, insurance and payout during construction;
  • It takes a long process to get such data; and some information is even not obtainable;
  • A letter from FHWA urging public and private supports may help.
  • The quality of some data, e.g., crash data, needs to be improved.

Work to Be Accomplished

  • Completion of the two tasks in this quarter;
  • Survey on implementation and compliance of WZ safety audit guidelines/practices;
  • Study on strategies for developing new WZ safety audit guidelines;
  • Identify other case study projects;
  • Plan for a workshop on work zone safety issues.
