... A study by Newman that examined 46 cities around the world provided strong evidence that high population density contributed to controlling PMM traffic demands (Newman and Kenworthy, 1989 ). Studies on the correlation between population density and transport characteristics have been carried out in other countries, and Asian counties with high population densities, including South Korea and Japan, have shown high interest in the subject (Morimoto and Koike, 1995) ...
... The residential sector consisted of about 14 % of total energy consumption in Japan (METI, 2010), 17 % in Canada (2013), and 22.4 % in The U.S. (EIA, 2020). Among different building subsectors, the residential buildings comprised around 40 % of the total building energy consumption (Koike, Morimono, Imamura, & Hidenobu, 2004). It cited that the energy demand of this sector tremendously relates to occupant behavior (D'Oca, Corgnati, & Buso, 2014). ...
... Vehicle owners revealed higher trip rates and longer trip distances than nonowners in Manila, Ho Chi Min, Yangon, Dhakka, and Colombo (Futose & Okamura, 2022). The high-income people revealed higher automobile shares and longer trip lengths in Phnom Penh, Manila, Chengdu, and Kuala Lumpur (Luo, Daimon, Morimoto, & Koike, 2007). The relationships between population density, GDP per capita, car ownership, and mode share of public transportation were analyzed, and the criteria to introduce urban mass transit were identified with the conditions of population and GDP (Koizumi, Nishimiya, & Kaneko, 2013). ...

... For example, high-rise buildings and high-density dwellings are more likely to be constructed close to metro stations (Guan, 2019;Lin et al., 2020;Wang et al., 2019;Yang et al., 2020). Furthermore, the capacity of the road network can be used to estimate the optimal and maximum housing floor area ratio (HFAR) and office and industry floor areas (Iravani, 2011;Li et al., 2020;Morimoto et al., 2000). Apart from this interaction, the transportation system also influences the urban form and housing market. ...
... 2) By analyzing the output signals of the IMU, the triaxial accelerometer, and the laser scanner, it is possible to correlate vertical acceleration, lateral acceleration, and yaw rate to the calculated road profile. The analysis of the signals shows that the unevenness of the road, caused by the misimplementation or damage of the road surface, leads to an increase in the vertical acceleration, this increase of the vertical acceleration -besides affecting cycling comfort [35], [36]-leads to an increase in the lateral acceleration and roll rate. This lateral instability of the bicycle may subsequently lead to rollover or lane departure. ...
... There are even broader applicability scenarios where mobility as a service (MaaS) suites enable individuals to combine modes of transportation and bundle route planning into a single price/application. While these applications show promise, they may have little effect when the dominant infrastructure available in urban transportation systems induces demand for automobility by default (Sarker et al. 2002). Depending on how and where AI is applied to mobility in cities, the technology can 'make or break' the vitality of urban transportation. ...
... In Japan, the bicycle has not been necessarily more accepted as a legitimate mode of transport in the Japanese transport hierarchy (Koike, 2000) Daily commuting is a key component of urban transport (Stinson et al., 2004). Representing the second most important purpose of bicycle use in Japan after shopping 9 , daily bicycle commuting is one reason why the bicycle has become a way of life and is deep-rooted in Japanese society as is in the Netherlands, where Europe's highest bicycle usage rates are observed (Pelzer 2010;Stoffers, 2012). ...
