The PuLS project examines the possibilities of digitalization in the context of challenges resulting from energy system transformation and urban processes using the example of parking and charging infrastructure sharing. In addition to public parking lots, charging points for electric vehicles on private property should also be usable with the PuLS platform. The availability of parking and charging stations will be recorded by sensors and made available in the PuLS platform so that live maps will be available to parking and charging station users. In addition to parking lot detection, the platform integrates traffic flow and air quality sensors for real-time monitoring. The provision of such a platform poses new challenges for energy and communication systems.
Based on typical network configurations from the PuLS pilot area, network-related charging management concepts are derived from reducing the dynamic load on the distributed electric vehicle charging points. In addition to the analysis of power grids, the utilization of communication networks through the integration of a multitude of distributed sensors will also be investigated. In this context, different communication network approaches such as public mobile radio (LTE / NB-IoT) and LoRaWAN as a relevant technology of Low Power Wide Area Networks will be examined in terms of their performance and compared with each other. For the analysis of the energy grid and communication networks, the requirements of the PuLS environment as well as network and data traffic models are converted into detailed scenarios and then simulatively investigated. For evaluation purposes, an end-to-end system demonstrator will be set up in a laboratory environment at TU Dortmund university, which enables a performance analysis based on real hardware. The considered communication networks will be further tested and evaluated in a field-setup in real environments.
Project duration: 01.12.2019 - 30.11.2022
The project is funded by the Federal Ministry of Transport and Digital Infrastructure under the funding reference 03EMF0203B.

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dortmund-Eichlinghofen” (closer to South Campus), and from B 1 / A 40 “Dortmund-Dorstfeld” (closer to North Campus). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from North Campus to South Campus by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Campus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station (“Dortmund Universität”). From there, suburban trains (S-Bahn) leave for Dortmund main station (“Dortmund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop “Dortmund Kampstraße”. From there, take U43 or U44 to the stop “Dortmund Wittener Straße”. Switch to bus line 447 and get off at “Dortmund Universität S”.
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on North Campus. One (“Dortmund Universität S”) is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
