“…The mean value and standard deviation of walking speed is shown in Table3. The values are the obtained by the statistics of walking speed in normal period [15]. In addition, the mean value is deteriorated by the effect of the street-blockade and the standard deviation is assumed to be not variable for the blockade in this study.…”

Damage estimation and disaster prevention plan for a Nankai megathrust earthquake which occurrence is assumed in the future have been formulated cabinet office of Japan based on lesson learned from the huge human damage caused by the tsunami of The Great East Japan Earthquake in 2011. Damage estimation for earthquake and tsunami is usually evaluated independently. For the damage estimation by tsunami, the human damage in evacuation from tsunami has been carried out. However, street-blockades have not been considered in many studies and damage estimations. When evacuation routes are changed by the street-blockades, configuration of the human damage in evacuation from tsunami seems to be different in no street-blockades. To evaluate total damage in whole area, unified treatment of the human damage by the both disasters seems to be significant. This study presents an evaluation method of human damage in evacuation from tsunami considering street-blockades using area-wide mesh. The author's method considering variances of tsunami run-up speed and walking speed is used to the evaluation. The street-blockades of evacuation routes are evaluated by using fragility curves of buildings for earthquake. Moreover, the difference in configuration of the human damage by consider the street-blockades and no blockades is discussed.

“…Each of these activities has a corresponding set of physical conditions that support it. Users determine which conditions are likely to satisfy them depending on the history and social background (Chen, Nakamura, & Kuma, 2014 (Matsumoto et al, 2009). Mansouri, Matsumoto, Aoki & Sugiyama (2011) identify the sky, ground, buildings, vegetation and actors (such as people) as the five main classes within a streetscape visual array.…”

“…Urban life and the consumer culture offer a platform for the coexistence of people with different objectives who may not be interested in advancing relations beyond the mutual respect on the street space (Zukin, 1998;Jacobs, 1961). The sense of community and the effect of street conditions on shopping streets also varies with the user groups (children, elderly, male, female) and all these entities must be part of decision making (Matsumoto et al 2009;Inoue et al, 2011). Ultimately, discourses on public space should be founded on an understanding of the evolution of the values and symbolism associated with the society in question (Lefebvre, 1991;Banerjee, 2001).…”

“…Micro-scale area studies about the contextual implications of car-free streets in neighbourhoods are therefore critical in understanding the relationship of local residents and adjacent shopping streets in Japan. The current understanding relies on fragments of research efforts targeted at particular aspects of streets such as studies on walking speed (Matsumoto, Kiyota & Ito, 2009), and studies related to the use of streets by elderly people (Sone & Kayama, 2009;Tsuboi & Kitano, 2010). Although shopping streets support day-to-day livelihoods of residents and offer a unique shopping experience for visitors in Tokyo, they are suffering serious decline.…”

For Centuries, local shopping streets in Japan have been central to the lives of communities as spaces for trading, various forms of social interactions, and for cultural festivals. However, uncontrolled motorisation and the convenience of shopping malls is reducing the streets' importance to the everyday life of residents. This study aimed at unearthing the underlying relationships between residents' attributes and the use of nearby shopping streets. The survey targeted residents in the vicinities of two shopping streets in Tokyo: Honcho-dori street in Adachi Ward and Pearl Centre in Suginami Ward. The results affirm the importance of local shopping streets to the lives of those living in their vicinities; this is evident in the prominence of residents' daily visits to the local shopping streets. Nonetheless, usage is largely restricted to necessary activities of shopping, while optional activities such as strolling and social interactions are sidelined in daily life. Additionally, years lived in the locality, the value placed on social interactions, and respondent's age are statistically significant in explaining residents' frequency of meeting acquaintances along the street in both cases although inconveniences and the reasons for choosing alternative destinations were additional explanations in Pearl Centre. We conclude that by evaluating the uniqueness of individual shopping streets and the population dynamics of the surroundings, urban planners can spur positive change for local residents to ensure functional, safe, and comfortable streets while encouraging rather than undermining business.

“…Moreover, based on the Suzuki, Yamaguchi and Oguri, Mechanical Engineering Journal, Vol.4, No.5 (2017) [DOI: 10.1299/mej.17-00215] average walking speed determined from survey results of 707 walkers' speeds on a city road (Matsumoto et al, 2009), we set the speed of a pedestrian crossing the road to 5 km/h. As indicated in Section "3.2 Braking operation timing for different pedestrian crossing speeds and vehicle velocities," the analysis results also show the results at different crossing velocity of pedestrians and the velocity of vehicles.…”

This study analyzes the brake operation behavior of drivers when a pedestrian runs out onto a road with good visibility. For this purpose, 15 subjects were observed in a driving simulator. As the evaluation criteria, we adopted the TTC to avoid the collision to pedestrian in the front/back direction at the start of braking and the spare distance between the pedestrian and the vehicle in the sideways direction at the start of braking. To determine the reliability of these test results, we also analyzed the initiation timing of a driver's braking operation in a real road environment using drive recorders and compared these results with those test results. Then, based on the results of this driving simulator test, we proposed the lowest 1% of the cumulative frequency of the driver's operation timings as the time of starting the brake operation in autonomous emergency braking. Finally, this proposed brake control timing's adequacy was validated in an experiment. The system's brake control did not interfere with the drivers' brake operation, confirming that driver overconfidence in the system was controlled.
