To perform these activities a work zone, or a temporary closing of a lane or shoulder, is required. However, work zones can have significant impacts on traffic flow, especially during peak travel times. To mitigate the impact of work zones, the Kansas Department of Transportation (KDOT) has developed a lane closure guide to assist KDOT personnel and contractors in determining times during the day and days of the week that a lane can be closed to traffic. Data were gathered from WICHway, the Intelligent Traffic System (ITS), for the Wichita, Kansas, region. Fifteen-minute traffic-count data were collected from WICHway for the three-and-a-half years from January 2016 through June 2019. The data were cleaned and put into two resources for contractors, a Microsoft Access Database and an ESRI Dashboard. The Access Database allows the user to identify a segment of interest from a list and see what times during the week a lane could be closed without slowing traffic flows. The ESRI Dashboard brings a spatial element to the same dataset that shows the highway links of interest on a map along with the traffic flow. These tools help contractors determine when and where lanes can be reasonably closed for construction efforts.
