BRIEF SUMMARY
BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates generally to a process and device for measuring the occupancy in passenger transportation means.
2. Description of the Prior Art
It is known to carry out passenger occupancy measurements, in particular in public transportation means such as buses, trains, and cable cars as well, whereby at an entrance gate appropriate passenger detectors are operated which perceive the passing through of passengers. For this purpose light barriers, turn stiles or the physical counting of passengers is used. It is the goal of such passenger occupancy measurements to establish the rate of utilization of the vehicle. Present devices suffer from significant disadvantages. For example, although present devices count the number of passengers passing the entrance gate, they cannot relate simultaneously to the number of passengers leaving the means of transportation.
To date it is not known how to carry out such a passenger occupancy measurement in passenger cars. Such an occupancy measurement, however, is extremely desirable as it provides a basis for allowing an increase in person utilization of individual passenger cars in private transportation. A passenger car as fully loaded as possible reduces the number of circulating vehicles. This is of particular importance in conurbations where the number of circulating vehicles should be reduced as much as possible.
Previous concepts regarding so-called traffic reduction were based on the assumption that more vehicles may actually be accommodated in the smallest possible space, e.g., by the building of parking structures, the construction of the appropriate expressways or by means of intelligent traffic management systems that were to assure a more favorable flow of traffic. The proposed systems are very expensive and require large amounts of public money and do not reduce traffic volume, i.e., providing no satisfactory solution to the problem. It has been shown that in industrialized countries, circulating passenger cars are occupied by no more than one or two passengers on average, which results in a low passenger utilization rate factor.
What is needed therefore is an effective process and device for the detection of passenger occupation rates in transportation means.


SUMMARY OF THE INVENTION

The preceding and other shortcomings of prior art processes and devices are addressed and overcome by the present invention which provides a process for tamper-proof measuring of vehicle occupancy in passenger transportation means whereby a counting of the transported persons is carried out and whereby the counting of passengers riding in the people transportation means takes place by means of individually assigned detectors, characterized in that measuring is carried out in such a manner that a manipulation of the measuring with the purpose of increasing the number of passenger is impossible or at least made very difficult and that data acquired is processed, stored and whereby the measurement is executed several times or continuously and whereby the measuring device is disposed completely inside the vehicle.
The present invention also provides a device for the execution of the process.
The foregoing and additional features and advantages of this invention will become apparent from the detailed description and accompanying drawing figures that follow. In the figures and the written description, numerals indicate the various features of the invention, like numerals referring to like features throughout for both the drawing figures and the written description.
