This report is a collection of papers presented at the workshop in November 1987 to discuss the collection, storage, retrieval, analysis and manipulation of visual data. The papers discuss a broad range of use of visual data, from video logging of the pavement, the road or the environment to recording traffic movements. Papers by arrb staff concentrated on techniques that were available for data collection and analysis whereas papers by the road engineers pragmatically discussed the possible use of these techniques and whether they were likely to be cost effective or not. The conclusions were extensive but can be briefly summarised as follows. There is a need for visual data in a road information system. The collection of this information may not be cost effective unless it is collected with some other parameter. However, to be of greatest use, the precise location of the recording must be known. It was recognised that visual data could be used for a variety of uses but that a number of small problems needed to be solved to get the most out of it. A list of possible research projects to solve these problems is given in the text. Finally there is a need for a coordinated effort or at least for all state road authorities (sra's) to be informed of progress in use of visual data in other sras (a).
