Autoguide is a route guidance system which gives advice based on current traffic information. This article describes a demonstration of autoguide held in London on 14th June 1988 with an adapted rover car. On-board equipment consists of a dashboard liquid crystal display (lcd) in two parts, a handset and a transceiver; one part of the lcd shows the destination legend, the other part displays the direction of travel, the countdown bars to the next turn, and the distance to travel. Destinations are chosen either by selecting a stored location number, or by entering the ordnance survey grid reference. After the start button in the handset has been pressed, the dashboard display shows the information stored on the system for the chosen destination. When the first road beacon is passed on the route, route guidance is activated. Visual and audible indications are given for route changes. A voice synthesiser is an optional feature. Autoguide is a zone based system, and route guidance ceases once the vehicle enters the last zone for the journey. The authors conclude that using autoguide would reduce journey times and distances travelled. There would also be a possible reduction in numbers of road accidents and a decrease in road accident costs. Safety considerations for autoguide include the need for accurate coding of instructions at complex junctions. Installing head up displays to replace dashboard displays might also enhance safety.
