  • One of them is, for example, a special charge, including automatic charging based on mileage, additional charges in busy areas of the center, and emergency network access fees. This will eliminate toll booths on the highway.
  • Other centres assist computers to perform supplementary calculations and emergency handling during particularly busy periods.
  • Special emergency vehicles are also equipped with a harassing device that changes the itinerary at any time and cannot predict its location.
  • the super level crossing network preferentially arranges parking spaces for buses, and even arranges parking spaces in advance, which cannot be occupied. Therefore, super level traffic network buses will not be congested, making buses have the same inherent advantages as subways.
  • the technology of super-flat transit bus priority using parking arrangements is incomparable with other bus priority measures.

  • the mode is as follows:
  • the community center has a community center station.
  • Drive short-distance buses and small public buses (this is called a point group model). Because buses and small public transit vehicles on this road system have the same characteristics as subways, they will not be slower than subways.
  • the road system of this point group model is the same-speed traffic system with the smallest investment / passenger ratio in large cities.
  • the speed is fast and the number of passengers is high. Traffic accidents are never allowed, and people are too slow to respond. Therefore, for high-speed buses, electronically controlled safety devices must be installed. Once the central computer detects a situation in front of the vehicle, it sends a message to start the electronically controlled vehicle to stop the vehicle and the subsequent series of vehicles more gently. , Not only safe, but also increase traffic (because the distance between cars can be reduced).
  • the super level traffic network also requires that cars on the road with speeds exceeding 60 kilometers, for example, also be fitted with safety devices.
  • Super level network constantly reminds the driver on the TV screen that the distance from the standard position is off. If the deviation is serious, the central computer activates the safety device, brakes it, and clears out. So super Level level traffic network is a network where drivers cannot violate regulations. Moreover, as long as an electronically controlled starting device is installed, the super level crossing network is a driverless automation network. The movement of the car is completely driven by the central computer precisely according to the position where the car should be located.

It can transmit information to the computer system and / or the electric braking device and the direction control device, so as to stop or change the direction of the vehicle.
  • Substituting super level crossing for ordinary intersections can greatly increase the throughput of intersections, and standard super level crossings can replace overpasses and greatly save money.
  • Super level crossing network brings super level crossing technology to a new level.

  • the Super Level Crossing Network is the most efficient intelligent driverless technology. After its adoption, citizens no longer need to learn to drive. What's more, the most troublesome car accident, which may be the biggest nuisance in the 21st century, may also disappear.
  • Super level public transportation may be the best alternative to the 20th century subway in the 21st century.

Abstract

Cette invention se rapporte à un système de routes et à un procédé de contrôle du trafic. Dans ce procédé, trois groupes de feux de signalisation sont placés sur chaque route de système de routes, avec un espacement préétabli entre eux. Plusieurs signaux d'espace de stationnement sont disposés sur au moins une voie entre les deux derniers groupes de feux de signalisation à une certaine distance du croisement. Chaque route de ce système de routes est en outre divisée en plusieurs sections. Le système de contrôle examine et gère l'état des espaces de stationnement de chaque section, puis donne des instructions aux contrôleurs présents dans les véhicules. Ce système de routes augmente notablement la fluidité du trafic à l'intersection et ce procédé de contrôle du trafic améliore considérablement les performances de ce système de routes. Grâce à cette invention, le temps de croisement du trafic redevient un temps plein.
