Abstract

<P>PROBLEM TO BE SOLVED: To solve such traffic congestion without spending much cost that, since the temporary stoppage of vehicles at tollbooths in a freeway causes traffic congestion, countermeasures against the congestion are taken by increasing the number of the tollbooths which however, result in congestion after the passage of the tollbooths because many vehicles intend to return to their original lanes, and the congestion caused by depriving other vehicles of a small number of the lanes occurs at exits of rest stations, or areas near entrances from other roads, or even if the vehicles take methods of electronic toll collection (ETC), i.e. a method of paying a toll by radio. <P>SOLUTION: A lane or a plurality of lanes in a zone including all of a congesting location and frontward and rearward areas where the congestion affects are separated from the other lanes, and automobiles traveling in the other lanes adjacent thereto are prevented from entering the separated lanes. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a structure for preventing traffic congestion on a car road.

  At the toll booth on the motorway, the vehicle temporarily stops to give and receive the fee, so the passing amount decreases. Therefore, if there are many vehicles that flow in, traffic jams will occur from that location. As a solution to this problem, a method of adding a fee gate has been taken.

  However, this time, after passing the toll gate, if you try to return to the original lane, there are more vehicles than the number of lanes, so you must drive slowly and stop repeatedly so as not to contact each other There is always a traffic jam as the number of inflowing vehicles increases.

  For this reason, the method of paying separately by fee (ETC) is also taken wirelessly, but because it is attached to the cash payment fee gate, the fee gate passes smoothly, but after that ETC trying to return to the few lanes The lane is competing with the vehicle that is not installed, and the effect cannot be demonstrated.

  The same traffic jam occurs at the exits of rest areas and near the entrances of other roads depending on the amount of inflow. The fundamental solution is to increase the number of lanes so that the number of lanes does not decrease even if they merge, but if that happens, the width of the road must be increased, resulting in problems of land acquisition and enormous costs. come.

  We want to prevent traffic jams without causing land acquisition and huge cost problems, and we want to resolve them as soon as possible.

  One lane or a plurality of lanes are separated from the other adjacent lanes so that the vehicle does not flow at least in all the sections where the traffic jams occur in the traffic jam location.

  Vehicles traveling in the separated lanes are where traffic jams occur, and lanes are no longer scrambled, and the traveling speed does not decrease, so the passing amount increases. As a result, the entire traffic jam location is free of traffic jams or even faster.

  The present invention will be described in two places, near the toll gate and at the junction. The junction includes not only entrances from other roads, but also exits of rest areas on highways and bus junctions.

  FIG. 1 shows an optimum example of the present invention, and FIG. 2 is a simple plan view showing the vicinity of a conventional toll gate. The vehicle travels from the right side to the left side on the drawing. Driving lanes to the front of the toll booth on the motorway 1 to 4, toll collection windows (hereinafter referred to as toll gates) 11 to 19, vehicles shown by ellipses passing there are 21 to 29, respectively, from the toll booth The travel lanes are 31-34.

  Conventionally, any lane can be freely changed in the vicinity of the toll gate as shown in FIG. 2, so if there are many inflowing vehicles, nine vehicles 21 to 29 that have passed through toll gates 11 to 19 They drive toward the toll gate exit, which is narrowed down to 4 lanes.

  Since the car is fast until the exit, the speed does not go out, but there is an increased risk of contact with an adjacent vehicle, so the speed must be further reduced, and in some cases, the car stops and passes through the opponent. Even if an ETC-equipped vehicle is able to exit the toll gate at 20 km / h, it must be slowed down if the vehicle comes in front. In this situation, even if ETC is installed, there is no effect.

  When this traffic jam occurs, this traffic traffic will naturally extend backwards, and will extend to more than 5 km in front of the toll booth. A traffic jam occurs at a low speed of 1 km or more. It takes about 2 hours to get through these traffic jams. If the vehicle travels only 3 km per hour, it is assumed that it occupies 10 m per vehicle, that is, if the vehicle length is 5 m, the distance between vehicles is 5 m, but 300 vehicles pass per hour per lane.

  In the present invention, as a countermeasure, for example, two lanes are to be separated, and the traveling lanes 1, 2 and 31, 32 are separated from other lanes. Since this separated lane can travel very quickly compared to the adjacent traffic lane, there is a risk of a collision because a vehicle that easily changes lanes appears at the lane change prohibition line. Therefore, the fence 10 which can prevent it is provided between the traveling lanes 2 and 3 and 32 and 33. For the time being, it would be enough to get from the end to the end of a car that had been congested at this toll booth in the past and then extended. And the fee gate will be dedicated to ETC.

  An ETC-equipped vehicle that runs in this lane can run on the flow with the traffic jam next to it. Since the speed passing through the toll gate is currently set at 20 km / h, assuming that this speed occupies 10 m per vehicle, it will pass 20 km per hour, so there will be 2000 vehicles passing per hour per lane. Furthermore, since the rate of passage of the toll gate can be improved by increasing the length of wireless transmission / reception, assuming that in the future, for example, the speed will be 60 km / h and occupy 20 m per vehicle, that is, the vehicle length is 5 m and the distance between vehicles is 15 m. The number of passing vehicles per lane will increase to 3000.

  In other words, the total number of vehicles in four lanes is 1200 cars at 300x4 per hour at the conventional toll booth, but at the toll booth of the present invention, 4600 cars at 2000x2 + 300x2 even when traveling at 20km / h. , Almost 4 times. If you drive at 60km / h, it will be 5.5 times faster. As a result, there is no traffic jam or it can be resolved in a short time.

  In this case, since the ETC-equipped vehicle must travel in the separated lane, the ratio of the separated lane depends on the number of the loaded vehicles used. If the number is small, the number of lanes must be reduced, and the effect is reduced. However, if the traffic jam distance of 6 km and the passage of 2 hours in the previous example can pass in 20 minutes at 20 km / h and in 6 minutes if the speed is 60 km / h, the number of cars to be equipped with ETC will surely increase and the effect will increase.

  The length of the fence to be separated is a requirement that the entrance does not get caught in the traffic jam of the adjacent lane. In the example of FIG. 2, the traffic jam ahead of the end toll gate can be resolved by reducing the number of toll gates. However, the starting length depends on the number of vehicles entering. No matter how much the toll gate efficiency increases due to separation, traffic congestion will occur if more vehicles flow in. Therefore, it is convenient to be able to adjust according to the situation.

  FIG. 3 is a simple plan view of the present invention, and FIG. 4 is a conventional plan view showing the vicinity of a merging point. Assuming that the main lane is 5 and 6, the inflow lane is 7, and the vehicles indicated by the ellipses above are 45, 46 and 47, respectively, the vehicle at the confluence is conventionally from 3 lanes as shown in FIG. Since it is reduced to two lanes, there is a high possibility that they will intrude into each other's lane, so the speed will inevitably drop, and if there are many traveling vehicles, there will be traffic jams.

  At that time, as shown in FIG. 3, the fence 10 which cannot pass between the lanes 5 and 6 is provided as long as there is an influence of the traffic jam. Then, the vehicle 45 traveling in the lane 5 can smoothly travel on the flow of the lane, like the toll booth, despite the confusion between the lane 6 and the lane 7. As a result, the number of passing vehicles increases, which contributes to an increase in the passing amount of the entire junction.

  By eliminating traffic jams or shortening the time, logistics and people move faster, and social efficiency becomes very high.

  The ability to pass smoothly on the road is not only very good for the driver's spirit but also reduces fatigue, leading to a reduction in accidents.

  Not only is unnecessary oil energy consumed during traffic jams reduced, but emissions of carbon dioxide and the like are also reduced.

  Considering the structure of an automobile road from the concept of the present invention, it is possible to eliminate useless road widths, lanes, and toll booths, and to efficiently make necessary investments.

  In the toll gate according to the present invention, since the effect of ETC is very high, the number of drivers to be mounted increases, so there is a high possibility that the efficiency and efficiency of the entire automobile exclusive road will be increased.
