The equipment, primarily developed to investigate the effects of traffic engineering techniques on vehicle fuel consumption, has been modified to collect data for automatic highway surveys. The design of the equipment is described with reference to the desirable requirements for portable data collection. The system is in two parts: a relatively simple self contained low powered field pack and a computer-compatible mains powered base pack. Up to eight events can be recorded on a normal audio cassette recorder. The base pack is used to transcribe the seven events, superimposed on a time base, on to punched paper tape, it also provides power for the field pack. The components of the event recorder are described, and an illustration is given of the computer processed output from a series of test-runs. (TRRL)
