Embodiment Construction
[0030] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0031] The present invention proposes a scheme transition method aiming at the direction change of the coordinated control of traffic arteries, which includes: determining the difference X between the time Z and the transition time when the current scheme runs through the last complete cycle; The intervals are respectively inserted into the corresponding transition phase or complete cycle, combined with the predicted phase saturation, the time of each transition phase is determined, and the time of each phase in the complete cycle is inserted, and then the transition method of the traffic arterial coordinated control scheme is obtained.
[0032] Specifically, the present invention adopts the following technical solutions:
[0033] Step S1, starting from the parking line of each entrance road at the intersection, and dividing each lane of each entrance road at t...

The invention provides a scheme transition method capable of aiming at direction change of arterial traffic coordination control. The method comprises the following steps that: determining a difference value X of a moment when a current scheme finishes being operated for a last integral period and a transition moment; carrying out interval division on the difference value X; aiming at each interval to independently insert a corresponding transition phase or integral period; combining with predicted phase saturability to determine each piece of transition phase time; and inserting each piece ofphase time in the integral period so as to obtain an arterial traffic coordination control scheme transition method. The method is used for lowering the influence of a signal control machine on ground transportation.
Description
technical field [0001] The invention relates to a transition method for a coordinated control scheme of an urban traffic trunk line from uplink priority to downlink priority, in particular to a scheme transition method for changing the coordinated control direction of a traffic trunk line. Background technique [0002] In the coordinated control of urban traffic arteries, there is often a phenomenon that the coordinated control scheme of the uplink priority arterial line is adopted in the previous period and the coordinated control scheme of the downlink priority arterial line is adopted in the next period. However, during the transition of the scheme, it is necessary to ensure that the number of transition cycles is small, and the duration of the transition period fluctuates less, so as to prevent the change of signal machine parameters during the transition from having a negative impact on urban traffic. Therefore, it has become an inevitable trend to develop a scheme tran...
