Deutsche Bahn: Data-Driven and Optimal Operations

CHALLENGE SOLUTION

Deutsche Bahn (DB) is the biggest train With the deployment of Ariadne surveyor operator in in the world and its operations devices, Deutsche Bahn is enabled to “You presented to us what cover almost every station in Germany as well monitor its passengers throughout their we expected to see in at as in Europe. Amongst others, the main entire journey, without violating any least 7 years. Monitoring problem DB faces, is the optimal revenue European privacy regulations. The accurate passenger flow is helping us share between its subsidiaries, which requires data and detailed analytics that Ariadne the identification of routes and transitions provided, allowed DB to measure the to optimize the length of between trains that passengers follow, in line following KPIs in real time: trains, improve our train with privacy. Moreover, they were in search schedule, distribute ticket for developing predictive maintenance for revenue between subsidiary their operations in- and out of stations. • The density of people in each Deutsche Bahn companies Besides; compartment and of course increase passenger satisfaction at the • Navigation of people inside the • The number of people getting in stations and in the train" stations and getting off the train in each Janis Diekman station Innovation Manager at • Number and location of passengers in Deutsche Bahn each compartment of the train • Actions of people after getting off the train – e.g. taking another train

• Optimal use of their spaces and or leaving the station

• Occupancy of each area in real time

• Understanding their passengers and the trends • The number of people each advertisement attracts and were some of their concerns. • Success of products in the retail area

BENEFITS

Ariadne surveyor system, and its combination with Ariadne Precise Localization and Dashboard, enabled Deutsche Bahn to understand their passengers better and find out the trends that they are forming. In particular,

• Ariadne surveyors have generated aggregated data of the people at the stations, which enabled Deutsche Bahn to better manage and offer improved service to its passengers. Besides, with the accumulated data, now the density of people at each point in time is predicted and necessary cautions are taken.

• Previously made by extra personnel, now the people counting operations are digitalized, which reduces costs and makes this service 7/24 possible.

Consequently, this results in more accurate and better decisions.

FURTHER BENEFITS AND USE CASES

- Navigation application for passengers - Data and analytics provision to the retail hub

- Equipment monitoring in the warehouse - Targeted advertising and marketing

- Suspicious behavior monitoring – safety - Lights adjusted according to the presence and the number of passengers - Optimal and efficient space usage

One can be either on the platform, or inside the compartment 1 or the compartment 2. As can be seen in the figure below, we could identify with 95% accuracy whether someone is located at level 0, while We identified with an accuracy of 99% whether one is we could identify with 89% accuracy whether someone is standing on the platform, 97% whether one is located in the located in at level 1. compartment 1 and with accuracy of 93% whether one is located in the compartment 2.

TECHNICAL DESCRIPTION ABOUT ARIADNE MAPS

Ariadne enables infrastructure Technology: RF localization Based: Difference owners to optimize their space by Time of Arrival precisely and anonymously tracking Scanning Frequencies the location of their visitors. Precise - Surveyor Type A 2.4 GHz & 5 GHz tracking is being achieved through our patented technology that - Surveyor Type B 500 GHz – 5 GHz enables the fusion of electromagnetic signals emitted by Power Connection 5V Micro USB smartphones in frequencies varied between 500MHz to 5GHz. The Current 330mA signals are captured through our proprietary hardware technology Size: 12 cm x 2.4 cm x 9 cm and estimation of the distance is

performed based on the signal Operation Temperature: 0o – 70o attenuation as well as the time
