General Logistics Plc, the privately owned developer of the Trafficmaster traffic in-car information system (CI No 2,311) would not comment on a report in the Sunday Telegraph that it is planning a stock market flotation early next year. Managing director David Martell said he could neither confirm or deny the story. Trafficmaster, the main string to the General’s bow, is based upon a series of infra-red sensors strung along motorways. When they detect traffic speed has fallen to 30mph a notification is sent back to the company’s headquarters in Leeds. From there the information is flashed to subscribers’ dash-board mounted units where it shows up as a symbol flashing on an LCD map. General Logistics is currently owned by Hambros Bank, Peek Holdings Plc and its own directors. The company made a loss of UKP669,034 in 1992 according to the Sunday Telegraph which says Allied Provincial will handle the flotation designed to fund domestic and overseas expansion. In the UK the company has 1,000 miles of motorway covered by around 800 sensors. It serves around 3,500 users and claims that between 50 and 100 are being added each month. Each user pays UKP200 for the in-car display, plus UKP50 for fitting plus UKP20 per month for the information feed. In the US, trials are under way with partner Westinghouse, other trials and licence applications are being pursued with un-named partners in Italy, Israel, Austria and Germany.
