Federal Highway AdministrationUS Transportation CollectionThe goal of this project was to develop implementation guidance that the Texas Department ofTransportation (TxDOT) can use to make better decisions regarding when and where to use positiveprotection in work zones and when to consider exposure control and other traffic control measures thatcould improve work zone safety. The specific objectives of the project were as follows:\ue2\u20ac\ua2 Analyze the benefits and costs of using portable concrete barrier (PCB) for positive protectionin work zones.\ue2\u20ac\ua2 Analyze the benefits and costs associated with the use of moveable and portable barriertechnologies that can be more quickly deployed and removed at work sites than traditional PCB.\ue2\u20ac\ua2 Analyze the benefits and costs of non-positive protection devices that can be used to improvesafety and reduce work zone intrusion events in work zones.\ue2\u20ac\ua2 Develop implementation guidelines for these various technologies.Researchers also developed guidelines for portable concrete barrier use in work zones. Guidelinesregarding the use of portable steel barrier, mobile barrier, and truck-mounted attenuators were alsodeveloped. General guidance and information regarding the use of exposure control measures and othert raffic control measures to reduce work space intrusion risks were also included in this report
