Abstract

An apparatus designed to automatically measure the total moving time, split times, time lag, and the like of each of a plurality of moving objects, and determine the arriving order of each moving object. Every time a plurality of moving objects, e.g., runners or vehicles, pass through each predetermined point, pieces of information such as total running/moving times, split times, time lags, and arriving orders are transmitted, in units of moving objects, to the respective moving objects or a transmission/reception unit arranged at each predetermined point. When moving objects pass through a predetermined point, and their moving times exceed passage times set in units of moving objects, an excess time is informed to each moving object.
