Due to the deterioration of the U. S. Highway system's pavements and bridges, construction rehabilitation has become a large scale effort. One of the safest and most efficient techniques for traffic control during rehabilitation of divided highways is two-lane two-way operation (TLTWO). In this technique, one side of the highway is closed off for repair while the other is put into TLTWO with channelizing devices to separate traffic. Current channelizing devices are a maintenance and safety problem due to frequent displacement, knockovers and failures. This project will develop a channelizing device that will self-restore when hit and keep the centerline well marked during extended periods of traffic flow. The proposal presents three concepts and describes a methodology that will be used in developing and testing a prototype channelizing device. Development of anchoring and removal techniques and tools will also be addressed in the proposed project.Anticipated results/potential commerical applications of results:The proposed project will develop and test a prototype self-restoring channelizing device after careful evaluation and analysis of potential concepts. The device will find commercial application by highway construction contractors as an upgrade for the inadequate devices currently available. The new devices will make travel through highway construction
