Problems solved by technology

As the traffic volume of urban roads continues to increase, it is more difficult for vehicles to enter and exit the ring road, and the traffic flow on the ring road is more dense. Vehicles entering the ring do not allow vehicles driving in the ring, and vehicles driving inside the ring do not give way to vehicles leaving the ring, which is prone to serious traffic jams. Incidents, and even the phenomenon of "traffic lock" in the whole ring, resulting in frequent accidents and low efficiency of traffic around the island

Abstract

The invention discloses a roundabout traffic diversion system. The roundabout traffic diversion system comprises a central roundabout (10), a ring road (11) around the roundabout (11) and a plurality of crossed branches (20) communicated with the ring road (11), wherein each branch (20) comprises a bidirectional inner branch road (21) and a bidirectional outer branch road (22); the ring road (11) comprises an inner ring road (12) and an outer ring road (13); the inner ring road (12) is communicated with the inner branch road (21); the outer ring road (13) is communicated with the outer branch road (22), and an isolation band (30) is arranged between the inner ring road (12) and the outer ring road (13), and is provided with a notch (31) so as to enable the inner branch road (21) to be communicated with the inner ring road (12). The roundabout traffic diversion system has the advantages of vehicle running rapidness and smoothness, and the traffic jam situation of the roundabout can be alleviated effectively.

Description

technical field [0001] The invention relates to intersection traffic planning, in particular to a roundabout traffic diversion system. Background technique [0002] Intersections are the bottlenecks of urban road traffic capacity. As an important part of urban roads, intersections are the "defiles" of traffic capacity in the road network and the "multiple sources" of traffic accidents. Due to the influence of non-machine interference and signal light control, the traffic capacity of each lane at the intersection is about 30% to 40% of the road section, and according to domestic and foreign traffic accident data, 35% to 60% of traffic accidents occur at intersections. . It can be seen that the reasonable channelization design and traffic organization of intersections are of great significance to reduce intersection delays, improve intersection capacity, and ensure traffic safety. [0003] A roundabout is a special type of level intersection with a center roundabout in the ...
