Safety evaluation of forced weaving as a traffic control measure in freeway maintenance operations. Paper presented at the 51st Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1972.

Effective traffic speed control during maintenance or reconstruction activity implies not only that the speed will be reduced enough to lower the conflict between work activity and traffic flow but also that no adverse conflicts will be introduced within the traffic stream. Speed control effectiveness and safety were analyzed for 2 examples of a traffic sign-traffic cone-traffic barricade pattern developed by the Iowa-state highway commission.
