In the concept of “green zone” setting, Beijing uses the central axis to divide it into a “green zone” in the outbound direction. It is generally suggested that the speed should be 40 kilometers per hour in the fourth ring and the fourth ring Outside 50 kilometers per hour. Time, morning and evening peak and night, “Green Belt ” out of the city more than the direction into the city to control the flow into the city; in the tidal conditions are obvious, the traffic flow of hot areas, will be optimized area control
