Abstract
The extent of the deployment of Intelligent Transportation Systems (ITSs) for work zone construction projects has increased in recent years. However, highway agencies are unable to meet the full demand of the deployment of ITSs in work zones in a fiscally constrained environment. Therefore, it is desirable to establish guidelines to help highway agencies to consider installing ITS in work zones as funding becomes available. The goal of this research is to develop a methodology and guideline to assist project designers in assessing whether a particular work zone construction or maintenance project should be considered for the deployment of one or more ITSs. If so, the guideline would assist in determining the ITSs that would be most appropriate for the project. To achieve this goal, the researchers: (1) investigated technologies and evaluated different ITSs that could be used in work zone projects, (2) selected the criteria that would have to be evaluated to identify the eligible work zone projects for the deployment of ITSs, and (3) developed a selection methodology to assist project designers in selecting one or more work zone ITSs in order to be deployed in the project. The outcomes of this study provide a guideline for use in selecting and implementing ITSs for a work zone construction or maintenance project.

A work zone is a segment of a road where roadwork takes place and may involve lane closures, detours and moving equipment
Most of the work zone construction and maintenance projects occur during the daylight hours or even nighttime when the traffic is passing through the work site

Summary
A work zone is a segment of a road where roadwork takes place and may involve lane closures, detours and moving equipment. Work Zone Intelligent Transportation Systems (ITSs) offer highway agencies the opportunity to reduce work zone-induced congestion, improve safety, and reduce the severity of crashes. Departments of Transportation (DOTs) in various states have installed ITSs in their work zones to manage the traffic and to mitigate the adverse impacts experienced by construction and maintenance workers and travelers [1]. Work zone ITSs are automated systems of devices that involve the use of a broad range of communications-based information and electronics technologies and provide accurate, real-time information to motorists and workers. These systems make it possible to anticipate and significantly reduce work zoneinduced congestion, thereby making the areas in and around work zones safer. Information provided by the work zone ITS may be in the form of real-time traffic conditions, such as travel time through a work zone, or recommended diversion routes that motorists can use
