Definitions

  • the invention relates to a method for monitoring road traffic and for early information and warning of road users in the event of traffic disruptions, their own misconduct, dangerous road conditions and / or critical weather conditions, and also to a traffic monitoring and information system used to carry out the method.
  • variable message signs can only be found at certain points at critical junctions. It is also unsatisfactory and, above all, that the periods from the respective traffic detection to the traffic influencing are too long in relation to the highly dynamic traffic events to warn the traffic in good time of identified critical traffic situations or even to reduce the risk of subsequent accidents if an accident is detected.
  • a traffic monitoring and information system is also known with radio beacons arranged at a distance from one another along a street with lights which are connected to a control room and are controlled via integrated receiving systems.
  • the receiving systems of the signal lights communicate with transmitters arranged in motor vehicles, which in turn are controlled by speed and crash sensors also installed in the vehicles and are used to control the lights in the radio beacons.
  • This traffic monitoring and information system is about a light chain system communicating with sensors installed in vehicles via suitable receiving and transmitting systems and thereby being able to send out corresponding warning signals when traffic-related driving conditions or even when individual vehicles or groups of vehicles are at a standstill .
  • the prerequisite for the fact that the driving conditions of a motor vehicle participating in traffic can be recorded and used to control the beacon system must be equipped with this vehicle corresponding sensors and a transmission system which can be controlled by the latter.
  • the driving conditions of all other motor vehicles participating in traffic cannot be detected and therefore cannot trigger information or warning signals.
  • the invention has for its object to provide a method of the type and intended use that dynamic monitoring of all road traffic in a section equipped with such a monitoring and information system and the early information and warning of road users and thus influencing the Enables traffic, but for which it is not necessary to equip the vehicles with the appropriate sensors and transmitters.
  • a traffic monitoring and information system for carrying out such a method is also to be created.
  • the object of the invention is achieved in that traffic and / or road conditions ascertained or entered by means of roadside traffic and load detection devices are displayed by means of illuminated elements with signal lights, arranged at intervals from one another along the road guidance, connected to light chains and controllable together or sequentially continuous traffic information and possibly warning in real time.
  • the invention therefore relates to the fact that, depending on traffic and / or road conditions which have been determined or also entered by the traffic and load detection devices, the road users information about these conditions and / or faults which have a direct effect on the behavior of the road users are brought to the attention by means of signal lights which are spaced apart from one another along the route of the road.
  • the light chains made of interconnected light elements can be operated continuously with a given light chain length as road guidance aids. This can be done, for example, with light pulses running forwards and backwards in two directions along the respective light chain, it being possible for pulse lengths, frequency and switch-on ratio to be variable.
  • the signal lights of the lighting elements can be operated in the blinking mode in the event of measured violations, such as excessive speed, truck overtaking ban, overloading of axles, wrong direction of travel or the like, and thus information for detected traffic violations can be given to the respective road user.
  • the light chains are expediently operated in real time in interaction with the traffic and / or load detection devices when using different fault detection algorithms.
  • the flashing modes of individual signal lights in front of a vehicle can also be visibly operated with the same running speed and the same route, and advantageously until the end of the detected violation. A road user is not only continuously informed about his misconduct, but also encouraged them to return to traffic-oriented driving.
  • another embodiment of the method according to the invention provides that the sensitivity to the visual threshold and the above-threshold brightness classification of the signal lights is increased or optimized in comparison to the permanent lighting by means of an ergonomically optimized pulse frequency, that is, the subjective conspicuousness is increased.
  • the lighting elements can also be operated with different brightness depending on the time of day or season (day / night, summer / winter).
  • Another important process design enables effective traffic influencing by the fact that the signal lights of the light chains are connected to one another with light elements running in the direction of travel along the light chain at the directional speed with the result that the road users make an intuitive effort to keep their driving speed at the same as that in the direction of travel adapting the given directional speed to the current light pulses. This necessarily leads to an equalization and calming of the traffic due to synchronous driving of all road users.
  • a still further process design provides that the signal lights of the light chains are operated with light impulses driving traffic and traveling in the direction of travel, in order not to do so to immediately resolve traffic-related congestion or viscous liquids in traffic, as can often occur, for example, in the event of an accident on the opposite lane or in spectacular but traffic-independent events. It can be expedient to operate the signal lamps of the lighting elements with differently colored light pulses. The lighting status of the lighting elements or lighting chains can also be monitored and controlled by a control room.
  • a road sensor system with a connected evaluation and control unit controls and activates several light chain elements backwards against the direction of traffic in order to inform the following traffic about traffic and / or road conditions in the section of the road ahead to transfer.
  • the method according to the invention can also be operated in such a way that to achieve real-time behavior and to cover continuous road sections, the light chains are operated either by activation by means of a road sensor element with evaluation electronics and automatic fault detection or manual activation, with the result of a shorter reaction time, by activation as a result of evaluating the traffic data from two or more sensors and evaluation units and comparative traffic data evaluation, which leads to an average response time, or by activation via evaluations of the sensors using methods in control rooms, which, however, requires a longer response time.

  • These can be individual pulses or group pulses in front of moving vehicles, but also synchronized light waves that are used to drive forward or backward at different frequencies to drive or slow down traffic.
  • the system can, however, also have a plurality of measuring points along a road at predetermined distances from one another with traffic and / or load detection devices, coupled lighting elements and at least one road processor as evaluation and control unit, so that a monitoring and information system covering at least sections is available.

  • 3 differs from the system structure explained above in connection with FIG. 2 in that the street processors 58, 59 include Appropriate slots for the individual functions are equipped and therefore no separate signal processors are required.
  • the road processor 75 illustrated in FIG. 4 is a device in which the individual functional elements are accommodated within a housing 76 which is encapsulated to the outside. Between a power supply 77, which is connected to an external power supply cable 78, and a buffer battery 80, five insertion locations are arranged, in which the various processor cards are accommodated. Thus, the central processor 82 with a leptop interface 83 is located directly next to the power supply 77, and two induction loop processor cards 84, 85, which are followed by an insert 86 for neural processing, are accommodated next to it. Between this insert and the buffer battery 80 there is then an insert 87 designed as an interface card data network, which is connected directly to a data interface modem 88 led out of the housing 76.
  • connection modules in the form of modular connection boards and these boards are equipped with terminal strips which provide the direct connection of the processor network, the sensors and a data interface for the signal network.
  • the processor network 90 is thus passed through a suitable cable bushing in the outer housing and connected to the connection board 91 which provides the connection to the central processor.
  • the connection to the associated sensor system is provided by connecting lines 94, 95 which are passed through cable bushings in the housing and are connected to the terminal strips of these connection boards.
  • the signal lines 97, 98 for driving the lighting elements are connected to the remaining connection board 96, which is connected to the data network interface card. Otherwise, the connection modules are equipped with integrated lightning protection.
  • the lighting element illustrated in FIG. 5 is a road guide post designed as a lighting post 100.
  • This guide post has the typical cross section in the form of an isosceles triangle and is anchored with its lower end on the edge of a road in the ground 101.
  • the tip of the triangular guide post cross section formed by the two legs of the triangle points towards the street and the surface facing the oncoming traffic is equipped with a rectangular reflector 102 which extends vertically in its main extension.
  • the convertibility from the conventional guide post to the light post 100 is conveyed by a guide post intermediate piece 105 which is designed as a module and which is arranged above the reflector 102 and in the manner shown in FIG. 6, each with a signal light 106, 106 'facing the oncoming and outgoing traffic and with a manually operated push button 107 is provided.
  • the guide post intermediate piece has a lower and an upper insertion section 108, 108 ', whose cross sections are adapted to the inner cross section of the guide post.
  • the intermediate piece 105 designed as a module is accommodated between the region of the guide post provided with the vertically extending reflector 102 and an upper guide post cap.
  • a floor housing 110 with a removable upper cover 111 is arranged in the ground 101, in which the electronics 112 belonging to this light element is accommodated.
  • the electronics is connected via a cable network 115 to the electronics of adjacent lighting elements and is connected to the signal lights 106, 106 'arranged in the guide post intermediate piece 105 and the push button 107 via lines 116, 117 and a contact plug 118, which can be used as a removal or Tear-off connector is designed and, in the event of malfunctions or other reasons, allows the guide post intermediate piece to be easily removed with the signal lights and the pushbutton.
  • the signal lights of the light post arranged in the guide post intermediate piece 105 are equipped with light area elements 120 in the form of LED arrays. These are LEDs 122 accommodated in a plastic frame 121, which are applied to a circuit board (not shown) in the interest of simple wiring and in the lower part of the plastic frame are shed. Casting the LEDs only in their lower area ensures that their brightness cannot be impaired by dirt when used outdoors because the domes of the LEDs are subject to a natural cleaning effect and the luminous flux is fixed on the domes.
