NEW POSSIBILITIES IN TRAFFIC DATA COLLECTION

UUTTA LIIKENTEEN MITTAUSTEKNIIKKAA

The rapid developments in electronics and data processing have opened new possibilities for traffic data collection. For example, a modern traffic counter or speed analyzer using microprocessors is a compact battery-driven programmable unit with semiconductor memory. A separate central unit is used to program the counter and to transport the data from the field to the office, where the data can be printed or transmitted to a (micro) computer. In detectors and sensors great development has also taken place. New physical principles in tribo and piezoelectronic sensors are coming into common use and others like the use of digital image processing are studied effectively. Old principles like induction loop techniques have also developed new possibilities with microprocessors, giving greater accuracy in vehicle speed and length measurements. (TRRL)
