Arrangement for, in a traffic route, establishing the distance of an object from a measurement point consisting of a central point or intersection point between two intersecting traffic routes

摘要

The invention relates to an arrangement for, in a traffic route, indicating the distance between a measurement point located in the middle of a road junction and a phenomenon along the street. The arrangement has a calculator which, on a first actuation of a change-over switch, is caused to calculate half the distance and, on a second actuation, is caused to calculate the full distance.
