Definitions
- the invention relates to a light signal display with a red, a yellow and a green signal light ("traffic light”), which are oriented facing the direction of travel of the traffic to be regulated.
- the invention is based on the object to provide a light signal display that avoids the occurrence of such accidents.
- the light signal display is provided with an aligned against the direction of travel sensor recognizes a seen in the direction of travel right next to a motor vehicle person and responsively modified the lights of the green signal light or flashing or flashing one to the coming Signal light adjacent arranged fourth signal light causes, recognizes in countries with left-hand traffic, a person located on the left next to the motor vehicle.
- the sensor may be an infrared sensor, alternatively a camera or a radar detector may be considered.
- the suitably aligned sensor detects the space (seen in the direction of travel) to the right of the vehicles (often so the bike path) and - when using an infrared sensor emanating from a person, increasing when approaching the traffic light heat radiation.
- the sensor actuates a device which effects a modification of the flare of the green signal light or illuminates a fourth signal light through which the driver of the vehicle beside which the cyclist is draws attention to the recognition of a person to the right of his vehicle.
- a camera may also be provided which analyzes the image taken by it and determines that an object next to the vehicle (seen to the right in the direction of travel) is moving toward the light signal display. Also in this case, the green signal light or a fourth, separate signal light is suitably controlled and warn the driver accordingly.
- the senor is designed as a radar device.
- the radar device can be designed such that its transmitter detects the radiated from the device and reflected by the cyclist radar beams.
- a circuit may be provided which continues the flashing or flashing of the warning signal beyond the period of detection of a person for a few seconds until it is ensured that the recognized person has actually left the danger zone. In determining this period of time, the ascertained approach speed of the person, in particular of the cyclist, can be taken into account.
- the sensor is integrated into the flow control of the traffic signal system, such that a signal releasing the intersection is displayed only when no person (more) is in the danger zone.
- the senor is included in the sequence control of the traffic signal system, such that a signal releasing the intersection is displayed only when no person is (anymore) in the danger zone.
