TL;DR: In this article, a design process has been developed to determine the necessity for temporary positive barriers systems in highway work zones and the expected number of hazardous vehicle encroachments into the work area is estimated based on the duration and length of the hazard, roadside clearance and cross slope, the roadway curvature and the traffic speed and volume.
Abstract: A design process has been developed to determine the necessity for temporary positive barriers systems in highway work zones The methodology includes two prescreening steps to determine whether site and traffic conditions constitute a probable or significant hazard In the third step, the expected number of hazardous vehicle encroachments into the work area is estimated based on the duration and length of the hazard, the roadside clearance and cross slope, the roadway curvature and the traffic speed and volume
