Optimization measures
In view of the problem that after the morning rush hour at the east exit of the intersection, the length of the left turn and the straight line is quite different, and the lane and the traffic flow do not match, the Kunming public security traffic police have adopted the traffic organization optimization measures of "variable guided lane" at the east exit of the intersection in accordance with the principle of "one mouth, one policy", so as to solve the problem of unstable time period and directional demand for traffic at the intersection. That is, the second lane at the east exit of the intersection of Renmin West Road and Huancheng West Road is set as a "variable guide lane", the words "variable lane" are painted on the ground, and two sets of lane division signs corresponding to the ground are set above the lane, let's learn how to pass the intersection:
