Definitions

  • the invention relates to a method for increasing the traffic volume of a road, and belongs to the technical field of transportation. Background technique
  • intersections are ubiquitous, and its negative impact on road traffic is self-evident. Without loss of generality, take the car straight through the intersection, and set the green light and red light time as an example, then the red light is on.
  • the car on the section in front of the intersection stops and waits for the green light, while the section behind the intersection is vacant, and the traffic capacity of the road is completely unutilized. It is only used within 50% of the time when the green light is on. Moreover, it takes time for each car to start and accelerate in sequence after the green light is on, and the actual utilization rate is definitely less than 50%. When there is more than one intersection along the road, the situation is even worse. It can be seen that the existence of intersections is an important reason for road traffic congestion.
  • One existing solution is to construct a three-dimensional intersection so that the traffic on the two intersecting roads does not affect each other. However, this law has a large investment, a large area, and a large maintenance and repair cost. In addition, especially in cities, the environmental changes it causes and the negative impacts of traffic on the surrounding facilities are often unacceptable.
  • the task of the present invention is to solve the above-mentioned intersection problem by a planar method, with low cost, low land use, and short cycle, and the ability of the road to pass through the traffic flow is greatly increased.
  • the congestion of traffic, especially urban traffic, will be considerably improved.
  • (1) is the traffic light, so that the number of lanes on the section before the intersection of the road before the intersection (2) and the section of the section behind the intersection (3) increases.
  • the new rear light segment (3) is made sufficiently long, the vehicle above it can be safely pre-conditioned on the road segment and merged into the original lane (4) during travel without having to stop completely.
  • a plurality of (N) parking lines (5) are arranged in each lane in the direction of the vehicle.
  • N the number of parking lines (5)
  • the size is such that when the red light turns green, the cars parked in front of the N parking lines (5) can be started at the same time.
  • the distance between the stopped vehicles in the current situation is too small, and each vehicle needs to wait for all the vehicles in front of them to move together and walk out a certain distance before starting the green light time waste, which can be reduced.
  • the traffic flow when the green light is on that is, the total traffic volume of the road is improved.
  • the 11th car needs to wait for the 10 cars in front of it to move together one after another and after driving. If each vehicle is started and walked for 2 seconds (actually greater than this number), the following car can be started. From the moment when the red light turns green, the 11th car needs to wait for 20 seconds before starting. This method can be omitted using the method of the present invention. If the time for each green light is 1-2 minutes, then for the 11th car, the waiting and wasted time saved by the above method is 33% - 16%.
  • the number N of parking lines mentioned above should be such that the stopped Nth car can only safely cross the traffic lights during the next green light.
  • the application of this method increases the length of the road occupied by the vehicle waiting for the red light, but it does not exceed the length of the road occupied by the vehicles when the vehicles maintain a safe distance, and thus does not cause a negative problem.
  • Another method of increasing the traffic volume of a road of the present invention is to notify the driver of each car at a plurality of locations on the road where the vehicle travels, at the point that the speed of the vehicle should be at the point in order to make the cars reach the intersection as much as possible.
  • the green light is on, the chance of encountering a red light and waiting for the red light to turn green is reduced.
  • the reference vehicle speed can be calculated from the state of the traffic light and the time of the transition, and the distance from each location to the traffic light. It can be sent to a receiver placed on each vehicle or via a LED screen set along the way.
  • the method of the present invention has the following advantages -
  • the speed of C-cars is increasing, saving time, fuel economy and environmental protection.
  • this embodiment discusses an intersection of a two-lane road. Before the road reaches the intersection before the intersection (2), the lanes of the original lane (4) are divided into two, two new lanes are added, and after the intersection (3) after the intersection , correspondingly added two new lanes.
  • the green light is on, the vehicles waiting in each lane pass through the intersection and enter the rear section of the light (3).
  • the vehicles on the priority lane (6) continue to move forward, while the vehicles on the other lanes are slower. Drive or stop waiting until the green light turns red, and the vehicle that has crossed the traffic light on the priority lane (6) has also finished, and then continue.
  • each parking line (5) is arranged in each lane of the front section of the lamp (2), and each line stops one car when the red light is on, and when the green light is on, there are a total of twenty vehicles (four lanes, Each of the six cars starts together in front of the set six parking lines (5), and increases the number of vehicles that can pass each time the green light is on.

Abstract

Procédé permettant d'augmenter le débit de la circulation des routes comportant un carrefour, en ajoutant le même nombre de voies d'accès à la partie avant (2), avant le feu de circulation, et de voies d'accès à la partie arrière (3), après le feu de circulation. Lorsque le feu de circulation est rouge, les véhicules s'arrêtent sur les voies d'accès pour attendre ; lorsque le feu de circulation est vert, les véhicules avancent pour traverser le carrefour et atteignent la partie arrière (3). Les véhicules dans les voies d'accès antérieures (6) peuvent continuer d'avancer, mais les véhicules dans d'autres voies d'accès devront ralentir ou s'arrêter pour attendre jusqu'à ce que le feu de circulation passe au rouge et que les voies d'accès antérieures (6) soient vides, puis iront dans les voies d'accès initiales (4) pour continuer d'avancer.
