Abstract

A traffic communication system comprising a laser transmitter arranged for emitting a pulsating laser signal, wherein at least one message has been encoded into the pulse sequence of the laser signal, a laser receiver arranged for receiving the pulsating laser signal, and a central processing unit arranged for determining said at least one message in the pulse sequence of the received signal and carrying out a command in dependence on the message received.

Claims

1-23. -23. (canceled)

24. A traffic communication system comprising:

a laser transmitter arranged for emitting a pulsating laser signal, with at least one message encoded into a pulse sequence of the laser signal;

a laser receiver arranged for receiving the pulsating laser signal; and

a central processing unit arranged for determining said at least one message in the pulse sequence of the received signal and carrying out a command in dependence on the message received.

25. The traffic communication system according to claim 24, further comprising an audio and/or visual output unit arranged for communicating the message to a driver of a vehicle.

26. The traffic communication system according to claim 24, wherein the signal processing unit is arranged for determining a multitude of messages in the pulse sequence of the received signal.

27. The traffic communication system according to claim 24, wherein the laser transmitter is arranged for emitting the pulsating laser signal in a plurality of directions.

28. The traffic communication system according to claim 24, wherein the laser receiver is arranged for receiving the pulsating laser signal at a plurality of locations.

29. The traffic communication system according to claim 24, further comprising at least one relay device comprising a laser receiver arranged for emitting a pulsating laser signal in response to the receipt of a pulsating laser signal by the laser receiver.

30. The traffic communication system according to claim 24, wherein the emitted pulsating laser signal is a copy of the received pulsating laser signal.

31. The traffic communication system according to claim 24, wherein the message to be transmitted is automatically triggered by an event in the vehicle in which the laser transmitter is located.

32. The traffic communication system according to claim 24, wherein said message comprises a text message.

33. The traffic communication system according to claim 24, further comprising an input device by means of which the driver can input a message, which message is encoded into the laser signal.

34. The traffic communication system according to claim 24, wherein the laser transmitter is a beacon disposed in a housing at a fixed roadside location.

35. The traffic communication system according to claim 34, wherein the beacon includes a laser receiver and a signal processing unit arranged for determining said at least one message in the pulse sequence of the received signal.

36. The traffic communication system according to claim 35, wherein the beacon includes a relay device.

37. The traffic communication system according to claim 24, wherein the laser transmitter is disposed in a first vehicle and the laser receiver is disposed in a second vehicle.

38. The traffic communication system according to claim 37, wherein the vehicle includes a laser transmitter as well as a laser receiver.

41. A laser transmitter according to claim 24.

42. A laser receiver according to claim 24.

43. A central processing unit according to claim 24.

44. A vehicle provided with at least a laser transmitter, a laser receiver and/or a central processing unit according to claim 24.

39. A traffic communication system comprising:

a laser transmitter arranged for emitting a pulsating laser signal;

a laser receiver arranged for receiving said pulsating laser signal; and

at least one relay device comprising a laser transmitter arranged for emitting a pulsating laser signal in response to the receipt of a pulsating laser signal by the laser receiver.

40. The traffic communication system according to claim 39, wherein the emitted pulsating laser signal is a copy of the received pulsating laser signal.

45. A method for communicating messages in traffic, wherein a pulsating laser signal is emitted by means of a laser transmitter, wherein said at least one message is encoded into a pulse sequence of the laser signal, and wherein a laser receiver received the pulsating laser signal and a central processing unit determines said at least one message in the pulse sequence of the received signal and carries out a command in dependence on the received message.

46. A method for communicating in traffic, wherein a pulsating laser signal is emitted by means of a laser transmitter, wherein a laser receiver in a vehicle received the pulsating laser signal, wherein a pulsating laser signal is emitted by a laser transmitter in the vehicle in response to the receipt of a pulsating laser signal by the laser receiver, and wherein the pulsating laser signal is emitted in rearward direction, seen in the direction of movement, by the laser transmitter in the vehicle.
