| 摘要： | The AutoFlagger consists of a stop/slow paddle and supplemental signs and lights mounted on a trailer that can be operated by remote control. The AutoFlagger is classified as an automated flagger assistance device (AFAD), which is a portable traffic control system that assists a flagger operation for short-term lane closures on two-lane highways. The primary benefit is to enhance the safety of flaggers by removing them from the roadway and moving traffic while also maintaining positive control of traffic approaching the work zone. Another important benefit is that under certain conditions, one flagger can control traffic, thereby allowing the second flagger to perform other duties. Two AutoFlagger units were purchased by the Virginia Department of Transportation (VDOT), and the deployment of the units was recorded and the comments by the users were described. Other AFAD systems used by other state departments of transportation were also reviewed. / NOTE:Final rept. |
