摘要：	Assessing the safety and mobility impacts of work zones across the project development phases of road construction and maintenance projects is an emphasis area of the Federal Highway Administration's Final Rule on Work Zone Safety and Mobility(Final Rule). Specifically, the design phase of developing traffic control plans requires performing a traffic analysis to estimate queue lengths, travel times, and delays to determine lane closure times. State departments of transportation (DOTs) must comply with the requirements of the Final Rule by October 2007. To this end, this study was conducted to provide the Virginia Department of Transportation (VDOT) with the state-of-the-practice tools that are available and used by other state agencies for estimating the traffic impacts at work zones.
