This paper presents the development of computerized work zone safety management system that applies the concept of decision support system (DSS) to facilitate the practitioners in designing and selecting safe and appropriate traffic control for work zone. The developed system is intended to eliminate the subjective decision-making process by gathering the pertaining information regarding traffic control selection within a knowledgebased system. The developed system can overcome the limitation of “typical” traffic control system as this developed system can incorporate all special geometry features such as horizontal and vertical sight distances, balancing of lane configuration, etc. The output of this developed package can provide the safer work zone strategies e.g. proper location of taper area/length, proper length of lane closure, suitable placement of warning devices such traffic signs, traffic cones, etc. In addition, the outputs of DSS are presented in a graphical/drawing form to ensure the friendly usage of this package.
