Abstract

A device for monitoring traffic is designed as a portable hand-held device and includes a measuring unit for measuring a traffic state such as speed of a vehicle, a microphone and a language or voice recorder. Furthermore, the device has a language generator which acoustically outputs the measuring result of the measuring unit. The acoustically output measuring result is also recorded by the language or voice recorder. This permits acoustic documentation of the measuring procedure and its circumstances.

Claims

1. A hand-held device for monitoring traffic, comprising:

a hand-held housing;

a measuring device for measuring of and generating data related to a traffic state of a vehicle without producing a vehicle-identifying video image, said measuring device being at least partially situated within said hand-held housing;

said measuring device including pick-up means for picking up audible speech observations and recording means for recording said audible speech observations;

a sound track carrier including a first sound track and a second sound track, said recording means including means for a recording said audible speech observations on said first track;

and said device for monitoring traffic further comprising means for recording said data generated by said measuring device on said second sound track.

2. A device as claimed in claim 1, wherein said pick-up means comprises a microphone.

3. A device as claimed in claim 1, wherein said measuring device comprises means for measuring speed of a vehicle.

4. A device as claimed in claim 3, wherein said speed measuring means is a laser speedometer.

5. A device as claimed in claim 1, wherein said device further comprises language generator means.

6. A device as claimed in claim 1, further comprising means for storing said data generated by said measuring device in association with audible speech observations simultaneously recorded by said recording means.

7. A device as claimed in claim 1, wherein said measuring device further comprises a data to voice synthesizer, whereby said synthesizer being controlled by said measuring device to acoustically output said data generated by said measuring device, said acoustically outputted measuring data being recorded on said second sound track.
