Intersection channelization and signal control method of four-phase clockwise passage enabling pattern

Abstract

The invention discloses an intersection channelization and signal control method of a four-phase clockwise passage enabling pattern. According to the method, during channelization of a road space, a street crossing non-motorway at an intersection is separated into an inner non-motorway body and an outer non-motorway body by a street crossing sidewalk, the street crossing non-motorway body on the outer side of the street crossing sidewalk is used for non-motor vehicles to go straight and move across a street at the corresponding phase, and the street crossing non-motorway body on the inner sideof the street crossing sidewalk is used for non-motor vehicles to turn left for secondary street crossing at each phase; the four-phase clockwise passage enabling pattern is adopted for signal control, and motor vehicles turning right and motor vehicles turning left or going straight at the same inlet channel are separately allowed to pass through. By means of the method, traffic interference among different traffic modes is reduced, intersected and opposite collision is avoided, and potential traffic safety hazards are reduced. Phase linkage is smooth through signal control without setting all-red time; the method is applicable to a situation that the traffic flow of inlet channels in four directions of the intersection is not balanced; the utilization rate of space-time resources is increased.

Description

technical field [0001] The present invention relates to the field of traffic design and control, in particular to a four-phase clockwise release method for separating right-turning motor vehicle flow, right-turning non-motor vehicle flow separation, crossing straight and left-turning non-motor vehicle flow separation at intersection channelization and signaling Control Method. Background technique [0002] The intersection is the bottleneck of road traffic capacity, which often restricts the service level of the entire road and even the road network. With the continuous increase of non-motorized vehicles in various cities, the conflicts caused by the non-motorized vehicles crossing the street gathered at the intersection give the intersection management organization It brings great challenges. The existing intersection traffic organization method, in terms of spatial channelization, sets the crossing non-motor vehicle lane before the crossing pedestrian crossing or integrate...

Problems solved by technology

[0009] Purpose of the invention: The present invention aims at the shortcomings of the symmetrical phase-released intersection where the non-motorized vehicle lane crossing the street is located before the pedestrian crossing, and proposes a four-phase clockwise clearing intersection channelization and signal control method to effectively reduce the number of traffic modes. Mutual traffic interference, avoiding crossing and opposite conflicts, reducing traffic safety hazards, and adapting to the unbalanced flow of entrance roads in four directions at cross-shaped intersections, can improve the utilization of space-time resources
