Several states leading the adoption and deployment of SWZ Technology Application efforts have been identified and information on their practices and points of contact are available.
Massachusetts DOT (MASSDOT) is working to develop and adopt business practices that will institutionalize the inclusion of work zone ITS into projects when and where appropriate. Smart work zone design standards have been drafted to assist in determining when an ITS application is necessary. A critical project characteristics matrix is also available to help select the appropriate type of ITS application. A scoring system has been developed to aid in the assessment process. A set of draft standard operating procedures have also been developed for contractors to better set expectations of what is required of them for deployment, operation, and maintenance. Plans are also to establish a concept of operations (ConOps) that will explain how and why smart work zones should be used, establish the requirements for data warehousing of smart work zone data, and develop a dashboard of work zone performance measures.

The Iowa Department of Transportation (Iowa DOT) Traffic Critical Projects (TCP) program was deployed to address safety and mobility challenges within work zones. This program identifies key work zones that will require an enhanced TMP, with components such as work zone ITS, limited construction hours, night work, lane rental contracting mechanisms, and Traffic Incident Management (TIM) plans. Work zone ITS equipment includes queue detection and work zone cameras to monitor traffic conditions at a centralized transportation operations center . Work zone conditions can be reporting to traffic via Dynamic Message Signs (DMS) and in the event of a work zone incident, the TIM includes plans to re-route traffic and notify police and first responders. With a system to monitor work zone data in place, Iowa DOT is now in the process of developing tools to analyze this data in conjunction with the Iowa State University Center for Transportation Research and Education.
