Evaluation of the Safety Effects of the I-77 Active Traffic and Safety Management System: Phase 2
Project No: 109737
Target Completion Date: September 30, 2018 Safety, Operations, and Traffic Engineering
About the project
This project seeks to determine the effectiveness of an Active Traffic and Safety Management System (ATSM) that is expected to be placed in service during the summer of 2016 on a 12 mile segment of Interstate 77 north of the North Carolina/Virginia line. A key feature of the ATSM is that it will contain variable speed limits (VSLs) which will change the posted speed based on current weather conditions, including fog, high winds, snow, and ice. This location is prone to very severe fog events, and a number of large multi-vehicle crashes have occurred at the site due to drivers traveling too fast for hazardous conditions.
