Abstract

A traffic lane control method for controlling lane traffic around an intersection is provided. The method includes dividing a road into one or more lanes. The method also includes providing a control line with a traffic light system or a lane control light system. Further, the method includes providing a control area with a pre-determined length before or after the control line in the direction of the traffic. The method also includes controlling traffic movement on the road by permitting a vehicle on one or more lanes to pass the control line, and controlling a traffic movement on the road by prohibiting a vehicle on other lane to pass the control line.

Claims

1. A traffic lane control method for controlling lane traffic, comprising:

dividing a road into one or more lanes;

providing a control line with a traffic light system or a lane control light system;

providing a control area with a pre-determined length before or after the control line in the direction of the traffic; and

controlling a traffic movement on the road by permitting a vehicle on one or more lanes to pass the control line; and

controlling a traffic movement on the road by prohibiting a vehicle on other lane to pass the control line.

2. The method of claim 1, wherein the lane traffic is around an intersection, further including:

providing a stop line close to the intersection with a traffic light system, a control line and the control line at a pre-determined distance from the stop line.

3. The method of claim 2, further including:

requiring vehicles to make lane choice decision after proceeding the control line; and

requiring vehicles to queue behind the stop line after completing the lane choice while the traffic control light system stops the traffic behind the stop line.

4. The method of claim 2, further including:

stopping the traffic behind the control line on one or more lanes at a first advanced time before stopping the traffic behind the stop line to allow the vehicles between the control line and the stop line to pass the intersection; and

resuming the traffic behind the control line on one or more lanes at a second advanced time before resuming the traffic between the stop line and the control line, while prohibiting traffic on other lanes behind the control line from entering the control area, wherein;

the vehicles are required to make lane choice decision and complete lane choice after proceeding the control line.

5. The method of claim 2, further including:

stopping the traffic behind the control line at a third advanced time before stopping the traffic behind the stop line to avoid the vehicles behind the control line entering the dilemma zone of the stop line moving at high speed when the yellow light of the stop line is on.

resuming the traffic behind the control line on one or more lanes at a fourth advanced time before resuming the traffic between the stop line and the control line, while prohibiting traffic on other lanes behind the control line from entering the control area, wherein;

the vehicles are required to make lane choice decision and complete lane choice after proceeding the control line.

6. The method of claim 2, when the road operation speed is below a pre-determined threshold, further including:

stopping the traffic behind the control line on one or more lanes for a pre-determined time period; and

permitting the traffic behind the control line on one or more lanes, wherein;

the vehicles are required to make lane choice decision and complete lane choice after proceeding the control line.

7. The method of claim 2, wherein:

one or two of the traffic light system and the lane control light system is configured to have one traffic light directing the traffic on one lane.

8. The method of claim 2, wherein:

a traffic light is configured to instruct a vehicle to stop and queue behind one or two of the stop line and the control line.

9. A method for controlling traffic, comprising:

providing a cushion zone with a first pre-determined length, a control zone with a second pre-determined length, and a rear zone on a road, the cushion zone being closest to a stop line with a traffic light system and the rear zone being farthest to the stop line, wherein a traffic on the road traveling in the direction from the rear zone to the stop line; and

instructing vehicles in the cushion zone, the control zone, and the rear zone during a traffic light cycle.

10. The method of claim 9, further including:

providing a warning line zone between the control zone and the rear zone by providing one or more warning line behind a rear border of the control zone.

11. The method of claim 10, wherein the traffic is around an intersection, the stop line located closest to the intersection, while a yellow light period is starting, further including:

requiring vehicles in the rear zone to stop behind the stop line;

suggesting vehicles in the warning line zone to stop behind the stop line;

suggesting vehicles in the control zone to pass the intersection; and

requiring vehicles in the cushion zone to pass the intersection.

12. The method of claim 10, wherein the traffic is around an intersection, the stop line located closest to the intersection, under Permissive yellow rule, while a yellow light period has already started, further including:

requiring vehicles in the warning line zone and rear zone to stop behind the stop line;

suggesting vehicles in the control zone to stop behind the stop line; and

vehicles in the cushion zone may stop behind the stop line or pass the intersection.

13. The method of claim 9, wherein:

the first pre-determined length and the second pre-determined length are a function of a speed limit of the road, wherein higher speed limit leads to longer pre-determined length.

14. The method of claim 9, wherein the traffic is around an intersection, the stop line located closest to the intersection, further including:

providing one or more stop box with a pre-determined stop box length behind the stop line on the road with the traffic approaching the intersection;

requiring a vehicle with a length below a pre-determined value to occupy a stop box, which permits only one vehicle to occupy, while the traffic on the road is stopped;

permitting vehicles in the stop box to start substantially simultaneously when the traffic on the road is permitted to resume.

15. The method of claim 14, wherein:

the stop box closer to the stop line has longer pre-determined stop box length.

16. The method of claim 14, wherein:

the vehicle is required to stop closer to a rear dividing line of the stop box.

17. A traffic resource allocation method for allocating traffic resources around a T shaped intersection formed by a first road and a second road, the method comprising:

dividing the first road into two or more first lanes at a first direction and two or more second lanes at a second direction opposite but parallel to the first direction;

dividing the second road into two or more third lanes at a third direction and two or more fourth lanes at a fourth direction opposite but parallel to the third direction; and

controlling traffic movements in the intersection by allocating traffic passing permit to pedestrian traffic and vehicle traffic on the first road and the second road, when permitting pedestrian traffic along the first direction and the second direction, permitting through vehicle traffic along the first direction and the second direction, and prohibiting turn traffic at any of the first, second, and third directions.

18. The method of claim 17, when permitting vehicle turn traffic from the first direction and vehicle turn traffic from the third direction,

permitting pedestrian traffic at the third and fourth direction;

and

prohibiting any other vehicle traffic, wherein;

the turn traffic from the first direction and the turn traffic from the third direction are opposite.

19. The method of claim 17, when permitting vehicle turn traffic from the second direction and vehicle turn traffic from the third direction,

permitting pedestrian traffic at the third and fourth direction;

and

prohibiting any other vehicle traffic, wherein;

the turn traffic from the second direction and the turn traffic from the third direction are opposite.

20. The method of claim 17, further including:

allocating traffic passing permit to a bicycle traffic, wherein the permit to bicycle traffic is the same to the permit to vehicle traffic.
