Abstract
Although fatalities, injuries as well as the frequency of road accidents in Japan decreased last year, accidents among taxi cabs are increasing steadily. Reasons behind such increment are not certain, but effective counter measures are highly expected. Image-recording type drive-video-recorder is a new technology to just meet this demand and has been distributing rapidly among taxi last few years. Human centred or driver oriented analysis with data obtained from 200 taxi-cabs in Tokyo revealed that this new technology is very useful for accident/near accident analysis and prevention as well. Tele-field study disclosed frequent bicycle related near accidents can be solved through positive improvement for road environment rather than education.
