Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
The application provides a signal control system of crossing developments straight right sharing lane, in this system, the crossing is provided with traffic signal lamp, this crossing is crossed by the road of first direction and the road of second direction and forms, can be cross intersection in fact also can be T style of calligraphy intersection, first direction and second direction are interweaved each other, it is comparatively typical, first direction and second direction mutually perpendicular, for example first direction and second direction are north-south direction and east-west direction respectively, it is actually probably not strictly perpendicular, but be applicable to the method of this application equally. Traffic signal lamp is according to the control of predetermineeing phase place signal timing, instructs the vehicle straight line/the left turn of letting pass the first direction and the vehicle straight line/the left turn of letting pass the second direction, and in this application, the right turn vehicle does not receive traffic signal lamp's control.
As shown in fig. 1, at least the entrance lane of the intersection in the first direction includes a straight right shared lane 1, and fig. 1 simplifies the lane in the east-west direction for the sake of simplifying the illustration, and only the exemplary entrance lane to the north-south direction shows the straight right shared lane 1. In the present application, the straight right shared lane is used for the right turn or the straight movement of the vehicle, and fig. 1 takes the first direction as the north-south direction and the second direction as the east-west direction as an example, and the length of the straight right shared lane of the entrance lane is denoted as L. The entrance lane is provided with a variable notice board 2 corresponding to the straight right sharing lane, and according to the conventional use habit, the variable notice board 2 can be arranged at the tail end position of the straight right sharing lane 1.
The sign that variable notice board 2 shows is variable, is used for instructing when variable notice board 2 shows different signs that the straight right sharing lane has different current functions, and the sign that variable notice board 2 shows in this application matches with the phase signal timing control mode linkage of traffic signal: leading phase duration t from the third phase of the traffic signal q Starting, emptying the phase time t before the end of the third phase of the traffic signal lamp k The variable notice board 2 displays a straight right indication sign 3, and the straight right indication sign 3 is used for indicating that a straight or right-turning vehicle enters a straight right shared lane and turns straight or right through the straight right shared lane according to a traffic signal lamp. During the remaining period other than this, the variable notice board 2 displays the right turn indicator 4, and the right turn indicator 4 is used to indicate that the right turn-only vehicle can enter the straight right shared lane and turn right via the straight right shared lane. The third phase of the traffic light is used to indicate that the vehicle in the first direction is released for straight travel.
Therefore, before the traffic light releases the straight-going vehicle in the first direction, the straight-going and/or right-turning vehicle can drive into the straight right shared lane, the right-turning vehicle can normally turn right, and the straight-going vehicle waits for releasing in the straight right shared lane. When the third phase is started, the straight vehicle in the straight right shared lane can normally go straight, and the right-turning vehicle can normally turn right. Before the third phase is finished, the variable notice board 2 skips to display the right turn indication mark 4, the straight vehicles are prohibited from entering the straight right shared lane, and the situation that the straight vehicles block the right turn vehicles from passing after the third phase is finished is avoided, so that the dislocation of the right turn flow and the straight flow in the time dimension is realized, and the passing efficiency is improved. And in order to make the effect of dislocation passing better, the time length t of the application to the preposed phase position q And a clear phase duration t k The following design is made:
in the present application, the leading phase duration t q Effective green duration t associated with third phase of traffic signal light g And direct right sharingThe length L of the lane corresponds. Specifically, the lead phase duration is
L is the length of the straight right shared lane, typically the solid length of the straight right shared lane at the approach lane. t is t g The effective green time of the third phase of the traffic signal lamp is determined according to the actual working condition of the traffic signal lamp. t is t 0 The time length of the first vehicle from the end of the straight right shared lane to the stop line after the variable notice board 2 jumps to the straight right indication sign 3 through the straight right shared lane is usually a preset value made according to practical experience, for example, 3s is adopted. l a The distance between the front ends of two adjacent vehicles is preset value according to practical experience, for example, 6m is adopted. C represents the traffic capacity of the straight right shared lane, and can be obtained by inquiring through a traffic capacity manual, so that the traffic capacity manual is a parameter with a known value. And T is the signal control period of the traffic signal lamp.
In the present application, the null phase duration t k Effective green duration t associated with third phase of traffic signal light g And (7) corresponding. Specifically, the clearing phase duration is
t 0 、t g 、l a C, T, see above for the meaning of the parameters.
More conventionally, the traffic signal lamp is generally controlled according to timing by using a four-phase signal, that is, the traffic signal lamp sequentially and circularly works according to the sequence of the first phase, the second phase, the third phase and the fourth phase, in this application, the first phase of the traffic signal lamp is used for indicating that a vehicle running along the second direction is released, and the second direction is perpendicular to the first direction, for example, when the first direction is a north-south direction in fig. 1, the second direction is an east-west direction. The second phase of the traffic signal is used to indicate that the vehicle is passing along the second direction for a left turn. The third phase of the traffic light is used to indicate that the vehicle traveling straight in the first direction is released, as described above. The fourth phase of the traffic light is used to indicate that the vehicle is released for a left turn in the first direction. The whole control process is as follows, please refer to fig. 2:
during the first phase of the traffic light, the variable notice board 2 continuously displays the right turn indicator 4.
When the traffic light jumps from the first phase to the second phase, the variable notice board 2 still keeps displaying the right turn indicator 4. When the second phase of the traffic signal lamp begins and continuously reaches the first time length t a Then, the variable notice board 2 is jumped from the right turn indication mark 4 to the straight right indication mark 3, and the first time length is t a ＝t 2 -t q ，t 2 For a control duration of the second phase, t q Is the leading phase duration.
When the traffic light jumps from the second phase to the third phase, the variable notice board 2 still keeps displaying the straight right indicator 3. When the third phase of the traffic signal lamp starts and continuously reaches the second time length t b Then, the direct right indicator 3 jumps to the right turn indicator 4, and the second time length is t b ＝t 3 -t k ，t 3 For the control duration of the third phase, t k To clear the phase duration.
When the traffic signal light jumps from the third phase to the fourth phase, the variable notice board 2 still keeps displaying the right turn indicator 4, and displays the right turn indicator 4 throughout the fourth phase.
When the traffic signal light jumps from the fourth phase to the first phase, the variable notice board 2 still keeps displaying the right turn indicator 4, and the above process is repeated.
