Abstract: A wall fastening is disclosed for a hollow wall, which includes a first section forming a hook configured to remain in front of the hollow wall and a second section which extends through a bore in the hollow wall and configured to fasten behind the hollow wall. The second section is bent, after insertion, in a final installation position, such that a tip at an end of a final section of the second section presses against a rear side of the hollow wall at a lateral distance, with a definable radius, from the bore in the hollow wall.

Abstract: A system and method collects transit vehicle arrival and departure data sent from the transit vehicle to a stationary control center. The stationary control center continuously calculates, a medial time table, a medial travel time to a destination on a transit route and a medial travel time between transit stops on the route. The medial values may be calculated differently for rush hour, holiday, or certain weather conditions to increase the accuracy of the schedule forecast. Actual position and time information of a transit vehicle may be transmitted via wireless communication from a transit vehicle to the stationary control center. The position and time information is transmitted at least when the transit vehicle arrives and departs each transit stop on the transit route. The medial values can be displayed to transit vehicle users.
