As part of a research programme to automate traffic data collection for the Department of Transport (DTP) the Transport and Road Research Laboratory (TRRL) together with industry, have produced prototype automatic vehicle classification equipment. When connected to suitable road sensors, this equipment is capable of classifying vehicles into 20 vehicle categories required by the DTP for its new national core census. A list of these categories is given. The classification methodology and road sensors employed are described. In addition to classification, the lane of occupation, vehicle length, wheelbase(s), speed and axle load may be obtained. Axle load has been obtained using the TRRL design of dynamic weighbridge. Some vehicle class and weight data, collected during 1982 from the M4 using these automated data collection techniques are included. The future potential for vehicle classification and axle load data is discussed, with relation to pavement damage and highway maintenance. For the covering abstract of the symposium see TRIS 396069.
