Problems solved by technology

[0003] However, the problem is that the Ad hoc network often cannot be set up quickly enough, or cannot be used for all vehicles depending on the hardware of each vehicle
Furthermore, the range of the communication is not sufficient to provide a speed recommendation for multiple traffic lights passing consecutively based on the speed of the traffic lights

Embodiment Construction

[0023] figure 1 Shown is a device 1 for controlling traffic flow, said device having a data server 2 with a database in which the positions P and switching times Si of traffic lights 3 for a plurality of traffic lights 3 are stored, wherein figure 1 Only one data item (P, Si) of the traffic signal 3 is shown. The database 2 of the data server is connected to a mobile radio communication device 4 which can request the position P and switching times Si of the traffic lights 3 via a mobile radio link 5 . For example, the mobile wireless link 5 can be one of the commercially available 2G, 2.5G, 2.75G, 3G or 4G mobile wireless networks, each of which can transmit data at different transmission speeds.

[0024] Vehicle 6 is usually already equipped with a corresponding mobile transmitting and receiving device 7 . Transmitter and receiver device 7 carries out multiple data transmissions from vehicle 6 , also for other functional units, and has an interface to traffic light status a...

Abstract

Abstract: The invention relates to a method and a device for controlling traffic flow. For this purpose, information about the time duration until a traffic light (3) is switched to another traffic light phase is utilized in order to provide a speed recommendation for approaching the traffic light (3) to the driver of a vehicle (6). In order to improve the determination of the speed recommendation, the invention provides that the position (P) and the switching times (Si) of a traffic light (3) are deposited in a database (2) and can be retrieved by a vehicle (6) via a mobile radio communication connection (5), and that the driver of the vehicle (6) is provided with the speed recommendation by utilizing this information.

Description

technical field [0001] The invention relates to a method and a device for controlling traffic flow. It is provided herein to use information about the period of time before a traffic light is switched to another traffic light state, in particular red, yellow or green (light state), in order to provide the vehicle driver with a route to said traffic light speed recommended. A traffic signal according to the invention is any traffic signal that provides an indication to vehicles in road traffic. Background technique [0002] In such a traffic light state aid, information about the period of time before the traffic light is switched to the next traffic light state, eg green to yellow, red, can be used to indicate to the driver: at which speed has a green wave (grüne Welle), ie whether the driver will be able to pass the traffic light in the green state, or the traffic light will switch to red before then and force the driver to stop. In order to realize the function of such ...
