Abstract

現在, 歩行速度の評価基準には定まったものがない。例えば10m15秒, 10m10秒あるいは健常人よりも若干遅めといったもので, その理論的根拠にも乏しい。はたして社会生活をしていく上でこの速さで十分であろうか? という疑問から, 少なくとも横断歩道を安全に渡れる速さがなければいけないのではないかと考えた。そこで130ヵ所の横断歩道の青信号の点灯点滅時間を調べ, 横断に必要な速さを算出した。その結果, 9割以上の横断歩道を渡るには1m/secの速さが必要であることがわかった。これを歩行評価基準の一つとすべきであるし, 訓練においてもこの速さを獲得すべきである。

Presently, we do not have a proper standard for evaluating a gait velocity. In the past, those based on unreliable data have been used such as ; the standard gait velocity is 15 sec. per 10 m for a physically handicapped person and 10 sec. per 10 m for healthy persons ; or in other words, that for a handicapped person is slightly longer than that for healthy persons. Is this speed sufficient for a normal social life? There is no time limit for moving indoors, but on the street, particularly at a crosswalk, certain speed is required to cross it safely. Therefore, in order to calculate the necessary speed for crossing crosswalks safely, we investigated the length of 130 crosswalks, the time duration of their green lights and of their blinking green lights. According to the results, the length of the crosswalks ranged from 6.4〜38.5 m (average 16.1±6.76 m). The time duration of the green lights was 10〜91 sec. (average 38.0±19.54 sec.) and the blinking green lights O〜5 sec. (average 4.8±0.88 sec.). By calculating the necessary time to cross a crosswalk, it is indicated that time durations of 1.31〜0.10 m/sec. for a green light and 1.06〜0.09 m/sec. for a green and blinking green light were needed. These results suggest that necessary gait velocity for crossing crosswalks safely is at least 1 m/sec. This should be regarded as one standard for evaluating a gait velocity in our actual rehabilitation.
