Florida Statewide and Regional ITS Architectures
This service package uses external measurements taken by the roadside infrastructure, and overheight alerts/warnings are communicated to the vehicle driver through roadside message boards. The infrastructure will display warning or reroute information when the measurements indicate that a vehicle does not have adequate height or width clearance. Specifically, the infrastructure data equipment detects and measures the approaching vehicle's height and width. The infrastructure component of the service package determines an overheight condition based on the vehicle measurements, along with bridge, overpass, or tunnel geometry. The driver is alerted through roadside message boards to the impending low height and/or narrow horizontal clearance tunnel prior to a decision point, enabling the vehicle to reroute and avoid a collision.
