Title:

AWEGS using Intellidrive℠ Architecture--A Proof of Concept

Abstract:

Advance Warning of End of Green Systems (AWEGS) have been successfully deployed across Texas to improve safety at high-speed signalized intersections. These systems have shown a reduction in red-light-running ranging from 30 to 45 percent. One of the objectives of IntelliDrive℠ systems is to improve safety. This paper describes a proof of concept of the development of an AWEGS type application for the IntelliDrive℠ environment. In an IntelliDrive℠ environment, vehicles and signal controllers are constantly exchanging messages using dedicated short range communications (DSRC) communication of the Vehicle to Infrastructure (V2I) architecture. The messages format and the contents have already been specified. AWEGS application uses this established architecture to improve intersection safety and warn the motorist about the end of green whenever necessary. There are numerous differences between the typical AWEGS application and an AWEGS application under IntelliDrive℠ environment. First of all the advance warning display will be in vehicle instead of a roadside sign. Second the decision to display the message is made by the On Board Equipment (OBE) in the vehicle instead of the system in the cabinet. Third and most importantly, a typical AWEGS warning is viewed and thus is applicable for all motorists on the approach that can view the sign. However, in an IntelliDrive℠ environment, the warning is vehicle specific and is only displayed for the vehicle that absolutely needs it. It is anticipated that AWEGS under an IntelliDrive℠ environment has potential to improve safety and eliminate some of the deficiencies of a typical AWEGS.
