Felix Kruse and René Kessler, together with colleagues from the Oldenburg company Hase & Igel and the L3S of the University of Hanover, have discovered inconsistencies in Google trend data and analysed them for patterns. An example of this is shown in the following figure. For the german term "Kurzarbeit", the trends were queried several times for 15.04 and 18.04 (solid lines). It can be expected that the results are always the same. In the figure you can see that the differences between the queries on 18.04 are very small and that the results are very similar. On 15.04 the individual queries differ considerably. The results lead to the need for a quality check before the data are used (e.g. in decision-making in companies or scientific studies). The full whitepaper can be downloaded from ResearchGate.

Cycling is a topic that moves many citizens in Oldenburg. A survey among cyclists in Oldenburg is now to provide new insights into the use of bicycles in everyday life. The survey takes place in the context of the EU project Bicycles and Intelligent Transport Systems (BITS), in which VLBA is involved as a project partner.
The project aims to find out, among other things, what barriers exist to the use of bicycles in everyday life in Oldenburg and whether citizens are satisfied with the promotion of cycling by the city of Oldenburg.
The study also includes a number of questions specific to Oldenburg. For example, cyclists will be asked to assess whether the dam should be converted into a cycle-only road in the future.
Participation in the survey is possible until Friday, 26 June 2020, under the following link.
Our research strives towards a completely new IT solution that will improve sustainability communication between companies and the financial community. To avoid time-consuming reading for several stakeholders and decision-makers, the prototype demonstrates the results of our research.
In several meetings, the project team presented interim results of the current implementation to individual experts within the company. These interim discussions were to refine this prototype regarding relevant functions.
Now, a second version of the prototype is almost complete. This version implements further important functions in addition to the basic functions. Thanks to constructive feedback, our team will start into the upcoming sprints of the ongoing implementation phase. In summer, the prototype version 2 will be completed.
On 02.04.2020 the Kick-Off Meeting of the PUUK project, which is funded by the DBU (Deutsche Bundesstiftung Umwelt), was successfully held. Due to the corona crisis the meeting took place in digital form.
The term PUUK stands for "Platform for a demand-oriented provision of environmental information by companies and municipalities with citizen participation". After a round of introductions of the project sponsors and project partners, an exchange about the goals of the project to be achieved took place. Different points, both platform-related and organisational, were discussed.
It is particularly worth mentioning that citizen participation is given a special role in the PUUK project. With the help of online surveys, expert interviews and workshops, the needs of citizens for environmental information portals are to be identified, which will be implemented in a prototypical development of a novel environmental information platform.
The following project partners are in the project consortium:
The City of Oldenburg supports PUUK in the requirements surveys for the platform to be developed and will make every effort to ensure that the platform to be developed for demand-oriented citizen information continues to be used beyond the end of the project. The city of Oldenburg will contribute its broad network of other municipalities and suitable stakeholders to the workshops to determine the specific needs of citizens for environmental information in order to support the creation of the necessary practical relevance of PUUK. In addition, the city of Oldenburg is making its environmental data available, which was collected using various sensors in the Oldenburg area.
leanact GmbH develops software solutions for municipalities, companies and public institutions. The company supports its customers in modernizing their information technology with citizen-oriented software that is user-friendly and easy to use. In addition to software, web and individual app development, leanact GmbH focuses on the area of digital defect management and offers municipalities the possibility of simple and automated processing of defect reports by their citizens through the administration tool MeldooPLUS. More than 15 cities, municipalities and public institutions are supported by the services of the company. With the help of digital business models, leanact GmbH will expand the potential of the generated database of citizens' needs for environmental data on the basis of the platform to be developed and will advocate its continued use beyond the end of the project.
Salzgitter Flachstahl GmbH is the largest steel subsidiary in the Salzgitter Group and is an active member of the working group of the Lower Saxony government commission "Environmental Policy in Times of Digital Change". As a manufacturer of high-quality steel products, it cooperates with vehicle manufacturers and their suppliers, tube/large-diameter tube manufacturers, cold rolling mills and the construction industry. In addition to participating in the expert workshops, Salzgitter Flachstahl GmbH will also be actively involved in PUUK by organizing expert interviews in order to record the demand for environmental data from a company perspective.
The Lower Saxony Climate Protection and Energy Agency (KEAN) is participating in the PUUK project as an associated partner. As the state's climate protection agency, it supports, informs and networks the many different players involved in the energy turnaround in Lower Saxony. It is very interested in understanding how the actors can inform citizens about energy and sustainability in a way that meets their needs.
The University of Oldenburg - Department of Business Informatics (VLBA), under the direction of Prof. Dr.-Ing. habil. Jorge Marx Gómez, has focused its research on company-wide corporate and inter-company information systems. Very Large Business Applications are characterized by their strategic importance, both for individual companies and for corporate networks. In particular, the handling of data in various forms (data collection, availability, preparation or preprocessing), as they can be found in a company environmental information system, is one of the department's main topics. The chair holder is also the director of the Center for Environment and Sustainability Research (COAST) and spokesperson of the department Operational Environmental Informatics in the German Informatics Society (GI e.V.). Within the project the VLBA pursues the goal of developing a platform for the demand-oriented provision of environmental data. For this purpose, expert interviews and workshops with companies and local authorities with citizen participation will be conducted.
A current interview on the bicycle sensor project ECOSense was recently published as part of the mFUND accompanying research. In the so called format "7 questions" project member and VLBA employee Johannes Schering gives an overview about objectives, challenges and first results of the one-year feasibility study. The interview has been published on the website of the Scientific Institute for Infrastructure and Communication Services (WIK), which is responsible for carrying out the formats of the mFUND accompanying research. The aim is to present the funded projects briefly and concisely to a wider audience and to further promote the exchange between the projects financially supported by mFUND.

Within the framework of a joint working group meeting on mobility in rural areas, NEMo and NiMo (Network for Intelligent Mobility) have started an interdisciplinary exchange. Various projects and initiatives from all over Germany met at the University of Vechta at the 4th of March to discuss various approaches to mobility outside urban centres. The VLBA members Johannes Schering and Ali Akyol gave a detailed overview about the results of the NEMo project and discussed the possibilities of continuing the collected findings in practical life.
The further lectures provided new exciting perspectives and insights into the activities of other actors. For example, Deutsche Bahn presented a mobile medical bus, which is in fact a mobile medical office that provides care for patients in the rural based northern part of Hessen county. With the sustainable bus stop shelter the company WSM from Waldbröl presented a new product for the public transport of the future. Further approaches from the University of Vechta and the University of Applied Sciences Osnabrück as well as from the municipality of Hoya showed various possible solutions to traffic problems in rural areas. All in all, the exchange offered a good platform to draw further attention to NEMo and to initiate new initiatives in new compositions.
The aim of the NiMo network is to develop a realistic and comprehensive vision of future mobility through interdisciplinary cooperation of various actors from the mobility sector and beyond, as well as through exchange with interested parties from all areas of society. On this basis, NiMo and its members develop and disseminate concepts, products and services for "intelligent mobility". The network includes a wide variety of players with a focus on sustainable mobility from the economy (start-ups, large companies such as Deutsche Bahn), administration and research from all over Germany.

From 18th to 20th of February the partners of the Interreg-project BITS (Bicycles and Intelligent Transport Systems) met up in Antwerp (Belgium) for a fourth internal project meeting. The partners involved reported about their process regarding bicycle data driven implementations as sensor systems, bicycle parking or gamification apps. The VLBA department presented first results of the bicycle data analysis part.
The Province of Antwerp hosted the three day partners meeting in the Provincehuis. The participants of the meeting traveled to Antwerp from the NSR partner countries involved as the Netherlands, Denmark, the United Kingdom, Germany and other parts of Belgium. In addition, the Advisory Group (AG) which will give strategic advise to the BITS project and consists of external experts as Roland Hentschel (City of Oldenburg) met for the first time.
VLBA research assistant Johannes Schering presented first results of the data analysis part. The Province of Antwerp tested an intelligent 3D camera system to measure near accidents at a dangerous crossroad. The VLBA team calculated the geo coordinates of all near accidents and identified times of the day when the most severe situations happenend including visualization. The speed levels of the cyclists were also calculated. Afterwards it will be decided how to publish the cleaned data set to the open data portal CycleDataHub (CDH) which is developed as part of the project.
Further inormation about the implementation at the crossroad can be found at the official BITS website: https://northsearegion.eu/bits/news/bits-pilot-on-3d-camera-technology-nominated-for-the-flemish-road-safety-award/
