PROBLEMS OF INSTRUMENTATION IN CAR-FOLLOWING RESEARCH
In theory, research into following-behaviour in real traffic is possible by means of an instrumented vehicle in traffic which records its own longitudinal movement and that of any randomly chosen following vehicle. Analysis of this measuring problem shows that for measuring the relative movement of the following vehicle, Doppler radar has the most suitable characteristics, but still falls short of requirements. Unless development of satisfactory apparatus is attempted, the conclusion to be drawn is that research into traffic flows will have to be restricted to the recording and analysis of less detailed data than accelerations and decelerations of individual vehicles.
