The current study simultaneously examines the effects of three different characteristics of the built environment based on the theoretical conceptualizations of density, diversity, and design (3D).doi:10.1016/j.jcrimjus.2021.101864Kim, Young-An

This paper examines the connection between the 3Ds of the built environment and travel demand. Notably, it tries to sort through the relative influences of the three dimensions after controlling for other explainers, like travellers' demographic characteristics. It does this mainly by applying the te...
The built environment is thought to influence travel demand along three principal dimensions; density, diversity, and design. This paper tests this proposition by examining how the `3Ds' affect trip rates and mode choice of residents in the San Francisco Bay Area. Models are estimated that relate...
In The Death and Life of Great American Cities, journalist Jane Jacobs identifies several possible advantages of density: increased walkability, close-knit communities, and a concentration of resources while maintaining diversity that better serves the population. Naturally, a higher population density ...

The spatial distribution of urban land and nighttime light of the 30 megacities in 2020 are shown in Figs. 3 and 4, respectively. The diversity of spatial distribution of various elements in cities can be attributed to factors such as geographical location, policy planning, and development directi...
Space-Time Transmit Diversity Schemes with Low-Density Parity-Check (LDPC) Codes Space-time transmit diversity (STTD) and space-time block coding (STBC) are attractive techniques for high bit-rate and high capacity transmission. The con... H Futaki,T Ohtsuki - 《Ieice Transactions on Communicati...
“even when you pack density, the street level, the storefront level, the ability for people to mix and mingle and not be stuck in these giant plazas, no man’s land, that is between big buildings, these wind-swept corridors” is what provides a city with diversity. He mentions that...
The larger the size, the higher the diversity of the population and the more likely it is to search for the global optimal solution, but the corresponding amount of calculation increases. If the population is too small, the convergence speed is accelerated but may fall into a local optimal ...
