HUGHES AND VAPOR TEAM TO DEVELOP 'SMART HIGHWAY' COMMUNICATIONS

 HUGHES AND VAPOR TEAM TO DEVELOP 'SMART HIGHWAY' COMMUNICATIONS
 FULLERTON, Calif., Jan. 28 /PRNewswire/ -- Drivers may be able to travel on California's future toll roads without having to stop at toll booths thanks to a new agreement between Hughes Aircraft Co. and Vapor operations of Mark IV Industries Inc.
 The companies have agreed to produce and market high-speed, digital vehicle-roadside communications systems that could be used in "smart highways" now in the planning stages in California and across the nation. The products will be compatible with advanced technology already being tested on California roads.
 Initial applications for the Hughes-Vapor vehicle-roadside communications products are expected to be electronic toll collection, improving vehicle operations through state ports of entry and weigh stations, tracking of hazardous materials and for monitoring of vehicle congestion.
 Urban and rural highway planners across the nation are determining the best way to use "smart" electronic communications, sensor, command and control and other high technology systems to improve the efficiency and flow of new and existing highways and surface roads.
 Hughes, a subsidiary of GM Hughes Electronics, and Vapor are two of the industry's leading developers of high technology equipment for use in the new generation of Intelligent Vehicle Highway Systems.
 The Hughes-Vapor products will be based on a high technology communications standard called the "slotted aloha" time division multiple access protocol. Hughes developed the protocol and plans to make it available to all companies through public domain disclosures.
 As opposed to other communications systems which allow roadside equipment to communicate with just one vehicle at a time, this new Hughes protocol will allow roadside radio equipment to communicate with all appropriately equipped passing vehicles regardless of lane position or speed.
 For toll roads, the system would allow vehicles in all lanes to drive at normal freeway speeds and have the vehicle owner information electronically relayed to the toll facility.
 The protocol is compatible and a complementary enhancement to the lane-based Heavy Vehicle Electronic License Plate program protocol that is currently used in California and other states by Vapor in a transportation identification application.
