The author discusses the requirements and uses of traffic data collection systems. Analysis of road traffic growth rates have been replaced by those of social, environmental, energy, economic and other effects of alternative options. The development of the present transport policies and programme (tpp) process is examined together with the way that data collection and processing methods have changed over the last 20 years. The 1968 Transport Act helped to shift the basis of transport project planning from a separate modal to a multi-modal basis. Although electronic equipment is used for traffic control, data capture and processing are less developed. Examples are given of urban traffic control, the monitoring of parking systems by a coded ticket method and bus control based on location data. The major topics found in current tpp's for urban areas and their data needs are discussed. The possbilities of using photographic techniques to supplement or replace current methods are reviewed. Topics considered include vehicle parking, road safety and maintenance where photographs can provide an effective method of checking the ratings of individual surveyors. Automatic data collection has many advantages but does not have the depth possible using photographic methods. However, the interpretation and coding of photographic data is not highly automated.
