Any new system would include a link to the City of Columbus computerized traffic signal system and the proposed freeway management system. Cincinnati Area - Metro is currently reviewing proposals for a new communications system with GPS and AVL capability. Akron Area - Akron Metro is deploying an ITS demonstration project which involves signal preemption in the downtown area. Lake County - Laketran is upgrading its communication system and will incorporate GPS and AVL, automated dispatching, and scheduling, and passenger information. However the communication system for the AVL is not compatible with the rest of the WRTA system, therefore use of the AVL has been temporarily suspended pending resolution of the problem.
Machine vision is used to identify truck queues on the exit ramp to the scale from the mainline.
The sign in advance of the ramp is controlled by a computer which uses counts from the Autoscope system. If the ramp is near capacity the sign is changed to indicate that the scale is closed temporarily. Once the queue has dissipated the sign is changed to indicate the scale is open. Current facilities are in Wood County and Hancock County and are part of a system which stretches from Canada to Florida. It is intended to be used for rural freeway work zones with minimal human supervision.
