Location analysis: Positioning of e-car charging poles in the district of Lippe

In 2015, Axel Häusler, Oliver Hall, and Benjamin Dally conducted a location analysis for the positioning of e-car charging poles within a framework of an expert report. The project was carried out as part of the program „Aggregation of electric mobility and renewable energies for intelligent commercial transport in rural areas through information and communication technology (ICT)” (“EMiLippe”).

The project EMiLippe (duration: September 1st, 2013 to August 31st, 2016) aims at the “development of an electric mobility system for commercial transports in rural areas under optimal use of renewable energies” within a cooperative project between the district of Lippe, several companies, and research facilities in the Region of OWL.

The chairs “Digital Media and Design”, “Urban Planning and Urban Design” and the research focus “urbanLab” of the Detmold School of Architecture and Interior Architecture serve as development basis for an experimental model for GIS-based localization of adequate e-car charging poles within the framework of the project. The methodical approach of this research assignment is composed of two independent approaches:
1.) Search of adequate locations regarding the earning of regenerative energies
2.) Search of adequate locations regarding the scope of electric cars within the street network

Both approaches can be understood as distrinct analysis tools. As a next analysis step, the gained knowledge is being put together. The common basis of both approaches is the spatial geographic boundary of the planning area. This is important in order to assess accessbility and the results on their content level. The project EMILippe refers to the general district boundaries in Lippe. However, the project also contains sites located further outside, e.g. the headquarters of the company itelligence AG in Bielefeld or the company Kannegießer in Vlotho. For this reason, the planning area has been determined as the whole administrative district Detmold. Also, only existent area and street objects within those adiminstrative boundaries have been determined.

The previous results of the project are the two regenerative energy sources solar energy and wind energy. Those two energy forms can be evaluated significantly relevant. The aim of the analysis is to spatially identify areas that are characterized by relatively good chances to administer the desired energy resources. Consequently, the official geo specialist data have been retrieved, especially the data of the Landesamt für Umwelt und Naturschutz [http://www.lanuv.nrw.de/]. In particular, the statistical geo specialist data of the Deutscher Wetterdiens that comprise the global solar radiation and the wind speeds with an altitude of 10 meters over the ground surface has been used for the location analysis that has been described in point number one. The further intersection of the gained spatial information with the settlement area data of the Regionalentwicklungsplan NRW (administrative district Detmold) and the available ALKIS data of the rural district Lippe enable us to adequately localize possible e-car charging poles regarding to energy production on the spot.

In order to expand on the specific particularities of the project subject, we use the second analysis step of a further examination of the location question regarding the relevant driving distances of all involved companies. In order to do so, different spatial action profiles that illustrate company specific path networks of the business traffic between start and endpoint typologically, are defined. In order to identify the most probable route, the three routing methods Floyd-Warshall, shortes way and the application of the empirically collected tracking data, are being used. By doing so, a huge number of different possibilities for entrepreneurial routes can be calculated realistically. The modeling of these routes that consider a certain vehicle range result in a meaningful picture of those regions with a critical charge status of the vehicle batteries.

The described location analysis uses rather general approaches and the results are being assessed within the framework of the project. The final application of the methods to the planning area represents a proof of concept. In addition, it is not just possible to apply the new insights into reality because certain decision-making parameters (e.g. the determined amount of the charging poles, the requirements to the charging pole location for the user, amounts, size, and spatial distribution of the users in the time of the procurement and analysis) were not available yet. If possible, the general assumptions have been used and the connecting points for prospective research works have been phrased.
