specific Embodiment approach 1

[0035] Specific Embodiment 1: A non-conflicting two-phase intersection traffic organization system described in this embodiment, the non-conflicting two-phase intersection traffic organization system includes a main signalized intersection M and an auxiliary signalized intersection, the Auxiliary signalized intersections are divided into auxiliary signalized intersections PW at the west entrance, auxiliary signalized intersections PS at the south entrance, auxiliary signalized intersection PE at the east entrance, and auxiliary signalized intersection PN at the north entrance; figure 2 shown;

[0036] For the west entrance of the main signalized intersection M, the forward direction of the traffic flow at the west entrance is taken as the reference direction;

[0037] Upstream of the auxiliary signalized intersection PW at the west entrance, the outermost lane on the right side of the reference direction is the right-turn lane, the left-hand lane of the right-turn lane is the...

specific Embodiment approach 2

[0054] Specific embodiment two: based on the signal timing method of a conflict-free two-phase intersection traffic organization system described in specific embodiment one, the method includes the following steps:

[0055] For the through traffic flow coming from the east, west, south and north entrances, when the green light of the straight auxiliary signal phase is on, the through traffic flow will travel from the stop line of the auxiliary signal intersection to the M stop line of the main signal intersection, and the through traffic flow will arrive at the main signal intersection At the stop line at exit M, the green light of the straight main signal phase is just turned on; for the left-turn traffic coming from the east, west, south and north entrances, when the green light of the left-turn main signal phase is on, the left-turn traffic flows from the main signal intersection M When the stop line reaches the stop line at the auxiliary signal intersection, and the left-tu...

specific Embodiment approach 3

[0059] Embodiment 3: The difference between this embodiment and Embodiment 2 is that for the through traffic coming from the east, west, south and north entrances, when the green light of the straight auxiliary signal phase is turned on, the through traffic flows from the auxiliary signal intersection. When the stop line reaches the M stop line at the main signal intersection, and the straight traffic flow reaches the M stop line at the main signal intersection, the green light of the straight main signal phase is just turned on; for the left-turn traffic flow coming from the east, west, south and north entrances, when After the green light of the left-turn main signal phase is on, the left-turn traffic flows from the main signal intersection M stop line to the auxiliary signal intersection stop line, and when the left-turn traffic flow reaches the auxiliary signal intersection stop line, the right-turn auxiliary signal phase green light just turns on bright; specifically:

Abstract

The invention provides a conflict-free two-phase intersection traffic organization system and a signal timing method, and belongs to the technical field of traffic engineering. By adoption of the conflict-free two-phase intersection traffic organization system and the signal timing method provided by the invention, the problem that left-turning vehicles in the existing two-phase conflict-free intersection encounters second time parking, such that the traffic benefits of the left-turning vehicles are lost, is solved. According to the conflict-free two-phase intersection traffic organization system and the signal timing method provided by the invention, by means of the timing coordination of a main signal and an auxiliary signal, left-turning, the straight-line and the right-turning vehiclesdo not encounter the second time parking problem, and the left-turning, the straight-line and the right-turning vehicles are simultaneously released at the intersection phase, thereby improving the traffic efficiency of the left-turning vehicles at the intersection; and moreover, the time difference of turning off the green lights of the main signal and the auxiliary signal is limited to preventthe vehicles from staying in a reverse right-turning lane or a straight lane between the main signal intersection and the auxiliary signal intersection, thereby avoiding the phenomenon of unstable signal control. The conflict-free two-phase intersection traffic organization system and the signal timing method provided by the invention can be applied to the technical field of traffic engineering.

Description

technical field [0001] The invention belongs to the technical field of traffic engineering, and in particular relates to a conflict-free two-phase intersection traffic organization system and a signal timing method. Background technique [0002] As the bottleneck point of urban road network, intersections hinder the smooth operation of urban traffic and affect residents' experience of urban life and travel. In the traditional classical intersection design, a two-phase signal scheme is set due to the straight-going conflict of two roads, and a left-turn protection phase is set due to the conflict between the left-turn and straight-going roads, so that the signal timing scheme becomes four-phase, which increases the lost time. However, only part of the lanes are used in each phase, which limits the improvement of the traffic capacity of the intersection. Therefore, we continue to optimize the timing of intersection signals and improve the control strategy based on the classic ...
