COMPUTERIZED OBSERVATIONS ON ROAD TRAFFIC

A fairly inexpensive computer-based system called the Traffic Engineering Logger (TEL) has recently been developed. It consists of a set of inductive loops in the road, a central unit, a battery pack, and a set of processing programs for a computer, such as a CDC or HP1000. The total cost of all these components is about R5 500. In addition, a data extractor costing about R2 200 is also required; however, one such unit may be shared among many TEL installations. The TEL is very versatile and can also produce information required for the evaluation of traffic signalization, measurement of the fuel consumption of individual vehicles, and for studies on axle weights. The paper first briefly explains the structure of the TEL and how it works, then it demonstrates by a practical example how comprehensive and very useful evidence on traffic is obtained from a very simple input.
