Determining Capacity and Selecting Appropriate Type of Control at One-Lane Two-Way Construction SitesAuthor/Presenter: Michalopoulos, Panos G.; Plum, Roger
The problem of determining the most appropriate type of traffic control at one-lane two-way construction sites (i.e., on two-lane two-way roadways where one lane is temporarily closed for repairs and the other must be shared by both directions of traffic) is addressed. Capacity and performance tables and figures are presented for stop-sign, signal, or flagger control. These were developed by a microscopic simulation program that was adjusted and calibrated from field data. Following safety and visibility constraints, selection of the most appropriate control type can be made from the capacity and performance estimations obtained from the methodology presented here along with some practical considerations. An overview of existing practices followed by most states is also presented.
