What were the goals/parameters (scale of the issue or opportunity)
Keeping track of a dynamic fleet of buses within a large indoor and underground space is a challenge. This was recognised by the management at the TPF bus depot in Switzerland where a Ubisense real-time location system (RTLS) has been installed in conjunction with a web-based depot management system software. This software was specifically developed for TPF to seamlessly work with SmartSpace, Ubisense’s modular software platform that uses real-time location and identification data from multiple sources to create mission-critical visibility and control applications.
The TPF depot management team were looking for a reliable and cost-effective RTLS that would improve the daily management of their bus depot.
In order to ensure each route is covered according to the timetable, the arrival and departure times of the buses must be monitored and maintained alerting key personnel to possible timetable deviation. Therefore, the precise location and positioning of each vehicle is critical to ensuring that they can be dispatched according to schedule and in the right order.
The Solution: How does Ubisense technology help you overcome your challenge or achieve your vision
A real-time location ultra-wide-band (UWB) radio system transmitter, known as a Ubisense tag, is attached to each bus. The tag emits small signals which are picked up by the network of Ubisense sensors located around the depot. The real-time location information is displayed within the depot management solution online interface enabling the despatch as to schedule and process-manage the depot efficiently.
The depot management system in conjunction with the Ubisense RTLS system has provided the perfect solution for the TPF bus depot offering 24/7 visibility of the buses across the depot and making significant efficiency improvements.
What have been the outcomes (results of the project)
- The precise and highly reliable Ubisense technology covers a critical process at TPF enabling an efficient operation of the public transport network. It is the key to TPF’s successful operational organisation.
- Complete 24/7 visibility of busses across the depot
- Consistently accurate location information allowing buses to be located in their correct lanes and parking spaces both indoors and outside
- Reliable communication with the depot management system alerting it to busses arriving and leaving the bus depot
- Considerable improvements of work-flow optimisation within the scheduling application
Mr Grégoire Ramuz, Head of Sales at TPF: “The real-time location ultra-wide-band (UWB) technology from Ubisense is the key to our operational organisation; we couldn’t operate our network without this technology. It is the only truly suited technology for indoor and underground depot bus location. I strongly appreciate the competence and expertise of all involved Ubisense staff. Also, the quality of support and installation documentation is excellent. I’m looking forward to working with Ubisense on extending the solution to more of our depots.”
