Concept Design
Importance of the main traffic roads having three lanes on each side, in total of six lanes is reduced to three lanes without a street isle. The previous road lanes have been adjusted to the bicycle lane and walking lane surrounded with shady landscape. They are advantages of trees and flowers lining as a separator between walking streets and traffic roads for users’ safety.
Components of routes, for example, bench, tram station, bicycle rack are located in shading areas to blend with the landscape, be well-organized and to not block the ways or make difficulty to street users. This promotes diverse activities in common areas, adding liveliness to it.
Pathway surface and street furniture design should consider to the universal design which has physical characteristics to facilitate all groups of street users, for example, smooth surface for wheelchairs, a sign or different type of surfaces at the ramp intersection, suitable height of bench, and spaces for wheelchairs.
