Traffic Control and Work Zone Safety for High Volume Roads

The Manual on Uniform Traffic Control Devices (MUTCD) predominantly addresses work performed along the centerline of roadways and low-speed roads. This work does not apply to the majority of situations encountered by New Jersey Department of Transportation (NJDOT) employees who survey or inspect high-speed, high-volume roadways. Therefore, there is a need to review current practices being used by other state DOTs and develop guidance for using traffic control devices (TCD) on high-volume roads for this targeted group.This research project reviews the current practices employed by the other state DOTs, and new and emerging safety technologies that are consistent with the MUTCD guidelines. Two traffic control devices were selected after the review process: (1) Temporary portable rumble strips and (2) advance warning lights. The effectiveness of these devices was evaluated based on field tests with the land surveying crew of NJDOT. Recommendations on using the traffic control devices and guidelines for surveyorsworking on/nearby roadways were summarized.
