Session No. 3E

Session Title: Turnpike Technology Transfer – Moving Traffic Forward!

Session Description: This session will highlight the Pennsylvania Turnpike Commission’s continuing improvement of its system via Traffic Engineering’s incorporation of advanced technology to improve safety, incorporation of its “new” Interchange Signing Plan to improve “positive guidance” and even statistical evaluation of safety measures to determine the impacts of the increased mainline Speed Limits to 70 mph. These sessions will summarize the use of the GPS-based Curve Advisory Reporting System (CARS), wrong-way compliance investigations and even introduce the Turnpike’s newest sign inventory system available to designers in 2018.
