This paper examined routine activities of elementary school children using GPS. Sixty students aged 7-8 and 10-11 in one elementary school participated in the experiment to track their after-school trips for 14 days. Questionnaire were concurrently filled by parents to ask destinations and companions of children’s trip. Individual trips other than group-home-to-trips (such as going to/from playground, visiting friends, attending private tutoring) were twice as long as school-home trips that much crime prevention efforts were currently paid. The frequency and length of the individual trips were examined by grade of subject, type of destination and companion. Routine activity theory was introduced to discuss policy implications in applying tracking technologies in safety of children.
