Devices and early warning methods used to reduce hits on low-clearance structures

Connecticut DOT used signing and flashing lights to warn oversize vehicles of low clearances and positions warnings far enough back to allow vehicles to exit highway prior to clearance restriction. The signing may consist of post-mounted signs or variable message signing.

They also used a system to map out oversize/overweight (OS/OW) vehicle routes through the state. The OS/OW unit has a listing of construction work zones and checks if any width or height restrictions exist. If so, the vehicle is re-routed.

Information of a product available through Mandli Communications allows measurement of vehicles at highway speeds from a laser scanner and will collect data and transmit remotely to a warning system or end user.
