Success Story with Düsseldorfer Rheinbahn AG and Hamburger Hochbahn AG

Highly-Precise Bus Positioning in Depots

"Before we installed the Symeo technology, someone had to search for and manually record the position of the buses. This effort has now been eliminated since the system automatically determines where the buses are parked. Our depot operations have been optimized as a result. The products were easy to install and function very reliably."

The challenge:
When public buses in large cities such as Hamburg and Düsseldorf are not on the road, they are normally parked at the depot. To make it easier to know exactly where the vehicles are located so that they can be fueled, maintained or cleaned, the public transit operators Düsseldorfer Rheinbahn AG and Hamburger Hochbahn AG began searching for a cost-effective, simple solution capable of automatically locating buses in fleets as large as several hundred vehicles. Employees previously had to walk through the depot to locate the position of the buses.

The solution: The two companies are now using Symeo’s wireless-based positioning technology to precisely detect and record the position of their entire bus fleets. Installed on each vehicle is a wireless receiver, the Symeo Positioning Unit (SPU), which independently determines the position of the bus without using a central server. The position and vehicle data is then transmitted over a proprietary frequency to a Symeo wireless data collection point, which in turn forwards the coordinates to the operator’s depot management system. The Symeo LPR®-2D technology thus enables the automatic positioning of the vehicles, down to the exact parking space, without using or interfering with the depot’s existing wireless network, which is utilized for transmitting enterprise data among other information.

The project´s success: More than 1,200 buses in the Hamburger Hochbahn depots in Hummelsbüttel, Mesterkamp, Harburg and Wandsbek, in addition to the Düsseldorfer Rheinbahn depots in Lierenfeld and Heerdt, have been equipped with the technology. Thanks to automatic positioning and reliable data transmission, both companies have optimized their depot operations and reduced workloads.
