CONTINUOUS WALKING DISTANCE AND CRITERIA FOR DENSITY OF RESTING PLACES

継続歩行距離と休憩施設の密度基準

 According to the technical advice from the government of Japan, continuous walking distance tends to range from 500 m to 700 m and the distance tends to be shortened as people get older. In the literature, it was found that (1) 65% of elderly persons are satisfied if the interval between resting places is shorter than 100 m; and (2) 70% of elderly persons are satisfied if its interval is shorter than 50 m. In particular, when walking around Tokyo central station and Otemachi station, continuous walking distance is more than 100 m. Although continuous walking distance tends to be longer than 100 m, a sufficient number of resting places is not provided. To make urban space more walkable for elderly persons, continuous walking distance needs to be decreased by increasing the number of resting places. However, the relationship between the continuous walking distance distribution and the density of resting places has not been sufficiently theoretically investigated. In this article, the authors investigated the aforementioned relationship with the application of the nearest neighbour distance distribution. Based on this theoretical model, the authors evaluated the number of resting places in order to improve continuous walking distribution. As the empirical study area, Tokyo central station and Otemachi station and their surroundings were selected. It was found that (1) the number of benches is 81 (67 (on the ground), 14 (under the ground)); (2) the number of resting places is 97 if flower beds are used as resting places; (3) the probability that the nearest distance between locations of benches is longer than 100 m is 0.28; (4) if flower beds are used as resting places, then its probability is 0.14; and (5) if its probability is to be close to 0, the number of additional resting places would be increased to 194 which is approximately 3 times larger than the present number. Based on these theoretical investigations, the authors proposed the following practical ways rather than increasing the number of benches per se. First, flower beds are improved such that their edges have the appropriate width to provide resting places. Second, stairs are improved to provide resting places. In particular, on the eastern side of Tokyo station at Yaesu gate, the number of resting places needs to be drastically increased. Improvement of stairs is a practical way because stairs are already used as resting places. Third, a practical way would be to provide resting places that are not for sitting.
