Dispositivo para medicion de vehiculo en carretera, que comprende estructura de soporte con eje orientado transversalmente sobre la carretera, pluralidad de elementos transmisores que se distribuyen a lo largo del eje y cada uno emite hacia abajo un haz de medicion de luz, al menos un elemento receptor instalado en la estructura, una unidad de evaluacion conectada a los elementos transmisores y receptores, en que las direcciones de emision de al menos dos transmisores no son paralelas entre si

摘要

The device has carrier structure whose support axis is oriented transversely over roadway. Several transmitter elements downwardly emit a light measuring beam. Each light measuring beam is located in emission direction extending normal to support axis of carrier structure. A receiver element which is installed on carrier structure receives reflected light measuring beams. An evaluation unit is connected to transmitter and receiver for time of flight measurement. The emission directions of two transmitter elements are not parallel to each other.
