Reconstruction of the ageing highway system in the United States is resulting in work zone delays, which are a growing irritant for motorists. The Federal Highway Administration and the National co-operative Highway Research Program sponsored a scanning tour through Germany, the Netherlands, Belgium, Scotland, and France to look at how those countries manage traffic flow through temporary work zones. The scanning team observed that highway agencies in those countries view the work zone as a marketplace, with drivers as “customers” who should be inconvenienced as little as possible. Emphasis is placed on developing a good communications plan and using Intelligent Transportation System technologies to keep drivers informed about roadwork projects. The scanning team recommendations include shortening contract times; improving communication with motorists; adopting a co-ordinated policy, planning, and programming approach to work zone planning and operations; possibly reducing lane widths; designing for future maintenance; and evaluating the use of yellow markings in work zones.
