1. A method for traffic monitoring, comprising the steps of:
- measuring data related to a traffic situation including a vehicle to be monitored;
generating a picture of a traffic scene related to said traffic situation on a photographic film;
recording said data on said photographic film by converting said data to a first set of binary energizing signals, said energizing signals energizing recording means so as to generate a numeric or alphanumeric representation of said data on said film in a first recording field thereof; and
converting said data to a second set of binary energizing signals, said second set of energizing signals energizing recording means so as to generate a neither numeric nor alphanumeric pattern on said film in a second recording field, said pattern representing said data in a format permitting reading of said data by a reading device and computer.

Abstract
In a method for traffic monitoring, data related to a traffic situation is measured. A picture of a traffic scene related to the traffic situation is generated on a photographic film. The data is recorded on the photographic film by converting the data to a first set of binary energizing signals which is energizing recording arrangements, so as to generate a numeric or alphanumeric representation of the data on the film in a first recording field thereof. The data is converted to a second set of binary energizing signals which energizes a recording arrangement, so as to generate a neither numeric nor alphanumeric pattern on the film in a second recording field.

12. A method for traffic monitoring, comprising the steps of:
-
measuring data related to a traffic situation including a vehicle to be monitored;
generating a picture of a traffic scene related to said traffic situation on a photographic film;
recording said data on said photographic film by converting said data to a first set of binary energizing signals, said energizing signals energizing recording means so as to generate a numeric or alphanumeric representation of said data on said film in a first recording field thereof;
converting said data to a second set of binary energizing signals, said second set of energizing signals energizing recording means so as to generate a neither numeric nor alphanumeric pattern on said film in a second recording field, said pattern representing said data in a format permitting reading of said data by a reading device and computer, an array of spots is defined in said second field, coloring or non-coloring of said array of spots representing data-dependent information, said secondary field being substantially rectangular and having a pair of substantially parallel sides extending in a direction of film feeding and another pair of sides extending transversely to the direction of film feeding;
wherein reading data recorded on the film in said second, substantially rectangular field consists of;
determining side lengths of said substantially rectangular field from spacing of marked corners of said substantially rectangular field;
determining coordinates of said spots as predetermined fractions of said side lengths; and
determining the colored and not-colored states at the locations determined by thus obtained coordinates. - View Dependent Claims (13, 14, 15)
