Portable, Non-Intrusive Advance Warning Devices for Work Zones with or without Flag Operators

Principal Investigator:

John Hourdos, Director, MN Traffic Observatory, Civil Engineering

Project Summary:

Studies have shown that some drivers disregard or ignore traffic-control devices and other driver-warning systems in work zones. This phenomenon has led to serious accidents and fatalities in work zones. The goal of this project is to develop and test a portable, non-intrusive, and low-cost intelligent drum line (IDL) warning device that can be easily and temporarily deployed along work zone areas. Each drum in the IDL will sense vehicle speed and present an audible warning to alert drivers. Conceptually, the effect on the driver will resemble that of a rumble stripe, such as those encountered just before toll booths. The system will serve as yet another layer of protection to work zone personnel and would be useful when other traffic-control systems are disregarded or fail.
