CABLE SYSTEMS FOR FUTURE RTI SYSTEMS. 1ST SEMINAR ON DATA ACQUISITION AND COMMUNICATION TECHNIQUES AND THEIR ASSESSMENT FOR ROAD TRANSPORT (DACAR), HELD AT CENTRE ALBERT BORSCHETTE, 36 RUE FROISSART, BRUSSELS, 6TH SEPTEMBER 1989

This paper presents a possible specification for an inductive cable system, suitable for use in road transport information (RTI) systems and designed to work under all weather and environmental conditions. An inductive cable system fully uses the magnetic field produced by the cable current. A roadside cable set, about 5 cm below the road surface, would be an inductive loop of average length 300 m, consisting of two wires situated symmetrically in the lane and 90 cm apart; the lane width would be about 3.5 m. A vehicle antenna set, about 25 cm above the road surface, would consist of two guidance coils and two sets of communication ferrites. Each roadside and vehicle set would have transmitter and receiver units for communication, guiding current unit and processor unit for overhead control. The roadside set would also have a sector control computer for vehicle management. The data communication bandwidth would be about 20 KHz for a data rate of 10 Kbits/sec; each roadside set and vehicle would use two such channels. The estimated costs would be 50 kECU per 1 km four-laned highway and 500 ECU per car (including guidance equipment). For the covering abstract of the seminar see IRRD 829799.
