DE2044706A1 - Traffic control system using anticipated information - Google Patents

Description

The invention relates to systems for traffic control and both of the traffic on the road, in the air and on the water as well as of separate and independent ones Means of transport ri.

Traffic control systems are already known which have the task of improving the traffic condition by regulating certain priority values, such as good and even traffic flow, safety, keeping the column lengths short, etc. These systems have the disadvantage that they do not foresee the emergence of critical situations, but only have the endeavor to

sideways - when they should occur.

On ge ;; e of the invention is the avoidance of the aforementioned Disadvantage by creating a system with which the formation of critical situations can be prevented and which has active, semi-active and passive gowns, u: n the headquarters temporally or spatially anticipated in-

^ fonnationen about the direction of travel and the chosen destination as well as about the choice of other sizes so that they can use the data obtained in this way in "real time" relate to future situations, process them, so that they process the distribution and conditions of traffic for the time ahead with suitable anticipation anticipate and then use the information that has been worked out in this way Evaluate the regulation of the traffic itself (e.g. traffic lights) and also provide the road users with those from the control center foreseen situation, the priority roads that

™ to indicate the speed to be stopped in order to prevent the emergence to keep columns as low as possible, avoid traffic jams and drive according to the criteria that are specific to the monitored zone.

Through the present invention, the control system is informed of the choice and future needs of the traffic with the greatest possible amount of time in advance and with regard to the space requirements and the intentions of the road users *

In addition, the Regeisyätem affects the traffic by it informs road users about the state of the traffic in a certain zone and in a certain future, as anticipated, informs and by monitoring the guidance of the vehicles (direction of travel, speed etc.), in that the control organs are operated.

The following is a general example of the invention in its application in the regulation of road traffic in ^ Connection with the enclosed block diagram described in more detail.

In the control system according to the invention for the aforementioned Road traffic provide traffic condition sensors 10 that will be described in more detail below, and the road users 14, the processing and programming center via the infrastructure 12, which is provided by liaison and compilation bodies the information is generated, information signals about the respective traffic volumes, how the traffic is to be controlled, via the climatic conditions, the presence of obstacles, etc. and about the intentions as well as about the goals the road user etc.

The center 16 works on the basis of the information listed above and possibly others in its programming

inserted information predicts the future course of traffic with a period of time in advance this depends on information and instructions that are suitable to enable road users to reach their destinations more quickly, to enable more skillful and secure and always transmitted by means of the connection means referred to as infrastructure 12 the mentioned information or instructions to road users 14 «

The sensors 10 can be in constant operation or they can also be operated from the control center 16 by means of the infrastructure 12 or can be activated directly by the road users themselves at the moment when their intervention is useful proves.

The system that anticipates the traffic situation can according to the invention be formed by

1) means of communication traffic user center via the successive choice of destinations, driving directions, speeds or other fourth;

2) Means for determining the road environment conditions (levers, accidents, columns of cars ...) and other current information about road trafficj

3) Means of communication between the street and the head office for

the findings under point 2);

¹ O means of summarizing the notifications and findings mentioned as well as the information mentioned;

5) means of elaboration of the mentioned information,

to get the prediction of the future situation of traffic;

6) Means for creating a program for the traffic light times based on the aforementioned forecast;

7) Means for passing on to the road user of the Information to enable successive choice of direction of travel;

8) Bodies to link the means mentioned to enable the exchange of information.

The aforementioned determination and notification means supply the control center with the information that this particular control center needs in order to achieve the particular goals and to influence the preselected values to be improved.

The means of determination, notification, compilation,

Sorting and signaling can take different forms and in this case can be:

Codified transceivers that transmit information, e.g. the chosen destinations of the vehicles, and the guidelines and receive instructions or /. record, which are developed and sent out by the headquarters;

Infrastructure systems, such as meshes, which are actively and / or passively coupled to the vehicle and are topographically distributed in this way are that they recognize the project and the preselected direction of travel of the vehicle;

Infrastructures with directional transmitting and receiving antennas equipped and able to determine the density of traffic coming from different zones, which also are topographically different so that they can distinguish the differently oriented traffic movements;

Color television cameras equipped with filter systems are suitable for distinguishing all vehicles that emit light signals about the preselected destination;

Laser, infrared, and electromagnetic Ultrashall- Ge Chambers, which also serve to the upper means of advance information that de means of energy fluctuations * the presence of the
