BLUE WATER BRIDGE BORDER APPROACH: VMS OPERATIONAL CONCEPT FOR NEW CHALLENGES

摘要

The planned widening of the Highway 402 approach corridor to the border toll plaza of thernBlue Water Bridge between Canada and U.S.A. presents new and exceptional challenges forrnVariable Message Sign (VMS) response. Some of the physical and operational challengesrninclude: a unique configuration (an express stream destined to the Bridge, and a localrncollector lane stream with closely spaced interchanges); separation of express traffic lanes byrnvehicle type and frequent border user efficiency programs, using pavement marking buffers;rndisplay of variable lane designations using segmented VMS messages; and display of lanespecificrnqueue warning information and incident information on VMS, layered over the lanerndesignation information. This paper describes the concept of operations for VMS response,rnwhich is intended to drive the automatic response generation software for this system.
