Safe and Effective Temporary Traffic Control for Mobile Operations on Two-Lane Roadways

Mobile operations can either move continuously along the roadway as during most striping operations, or intermittently as during a pothole patching operation. Mobile operations on two-lane roadways present unique challenges to transportation agencies, not the least of which is the highly variable conditions encountered in the field.

The TRB National Cooperative Highway Research Program’s NCHRP Web-Only Document 354: Safe and Effective Temporary Traffic Control for Mobile Operations on Two-Lane Roadways describes the available Temporary Traffic Control (TTC) strategies currently in use, itemizes the perceived hazards and practical challenges associated with implementation of those strategies, and explains how maintenance crews can adjust TTC strategies based on actual field conditions.
