This paper reports the results of implementing the principle of segregating motorised and non-motorised traffic in several large cities in China. It presents detailed examples of intersection traffic operation and unique types of interchanges, with respect to this principle, which segregates traffic by: (1) spatial separation at the same time; or (2) temporal separation in the same space. In Chinese cities with heavy bicycle traffic, major operational problems occur in: (1) narrow roads, or roads with saturated bicycle flows, where bicycles mix with other vehicles; (2) at level intersections; and (3) at intersections of alleys with streets in inner-city areas. Intersections have various types of various types of traffic conflict involving bicycles. Engineering measures at intersections include: (1) bicycle-banned areas; (2) a second stop line for cyclists; and (3) special waiting areas for turning bicycles. Regulatory measures include: (1) one-way bicycle roads; (2) turn prohibitions; and (3) changeable traffic lanes. Two general types of non-motor vehicle pathway measures have been implemented at interchanges: (1) mixed-traffic interchanges; and (2) divided-traffic interchanges, including those with cloverleaf and roundabout patterns.
