Pre-Class Tolling - White Paper

This white paper outlines some of the issues related to Automatic Vehicle Classification (AVC) in tolling pre-class systems. It will address both the problems and possible ways of solving them. It is the authors contention that unless all factors affecting such a system are properly aired then a successful deployment is unlikely. This paper offers a technical solution whilst highlighting the issues which arise and how these can be resolved.

ORT Front and Rear Triggers from a Single Gantry using Idris Loops

There are substantial cost advantages in using a single gantry for ORT plaza sites, and Idris can straightforwardly manage the tracking of vehicles from the tag read zone through to the trigger point for all current VES systems. The maximum array length for a 4 loop Idris system is 54ft, which more than accommodates all current VES focal lengths. When both front and rear triggers are required, the situation can get more difficult. This paper discusses some ways of accommodating the required tracking zone using Idris capabilities.
