Reducing Traffic Crashes at Road Construction Access Points

项目名称：	Reducing Traffic Crashes at Road Construction Access Points
摘要：	Technologies that can detect when a construction vehicle is about to enter main-lane traffic and warn approaching vehicles through electronic signing are available, but their effectiveness in reducing crash risk has not been thoroughly evaluated. Clear guidance is needed on the technologies available and of interest to TxDOT, including design, placement, delineation of ingress and egress points for work zones on roadways. These crash reduction technologies need to be tested for their effectiveness in the field at a sample of construction zones. This guidance will enhance the safety of road workers and road users by preventing crashes and adequately protecting workers in work zones. The purpose of this research is to compile crash and operational data and perform a comprehensive assessment of the risk factors and root causes of crashes at road construction and maintenance access points and document crash history and causal factors such as road speed limit, traffic volumes, type of facility, the available access point warning technologies, and a review of flagging methodologies, ultimately providing a evaluation of the various methods in reducing crash risks at work zones entrances and exits.
