One solution would be to construct a system of grade - separated walkways throughout much of the urban area . these walkways would need direct access to buildings and transport interchanges , escalator approaches from ground level , and could incorporate travelators and air - conditioning 在市区范围内兴建一些与车路分隔的行人通道设施,是一个解决方法。这些行人通道须直达各大厦及交通交汇处,有自动电梯连接地面,并可设有自动行人道及空气调节。
