TRAFFIC DATA FROM VIDEO RECORDINGS

Video recording, normally in black and white, can be used in much the same way as 16 mm photographic techniques. The author examines the relative merits of both systems and describes some recent applications of the video technique. A time-lapse recorder is shown to be an economic means of carrying out studies of vehicle manoeuvres and traffic volume counts. Conventional video recorders have been used to study simple vehicle or pedestrian timings. The study utilised existing surveillance cameras on motorways, and another used a surveillance camera in a city centre. Video recordings are useful for making visual and qualitative assessments of traffic situations and television techniques can be used to combine traffic views with superimposed displays. One such system has been used to study close following behaviour on motorways. Another system described has been developed to enable the collection and rapid interpretation and analysis of traffic data. This system uses an extensive suite of computer programs with television and video recording techniques. It has been used to study merging motorway traffic. Programs also exist for the study of vehicle trajectory, lane changing and gaps and headway determination. (TRRL)
