- TextdokumentFlexible Software Support for Mobility Services(INFORMATIK 2017, 2017) Akyol, Ali; Halberstadt, Jantje; Hebig, Kimberly; Jelschen, Jan; Winter, Andreas; Sandau, Alexander; Gómez, Jorge MarxDemographic change and growing urbanization are essential reasons for the increasing demand for mobility in rural areas in Germany. Municipalities in sparsely populated counties are confronted with the problem of providing a basic supply of public mobility services. Especially for rural areas, established public transport means have to be complemented by additional, new, and innovative mobility services. NEMo (Sustainable satisfaction of mobility demands in rural regions) pursues the development of sustainable and innovative mobility services based on tailored business models for rural areas. Traveler information systems are enhanced to handle a range of active and passive mobility services in a very flexible way. Within this paper, three flexible cases are demonstrated. The SENSEI framework for software evolution provides improved software support by adding and modifying capabilities of the existing services to re-orchestrate and re-implement mobility services.
- KonferenzbeitragTelemetric Transportation Mode Validation(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Sandau, Alexander; Stamer, DanielThis paper introduces a model for the validation of transportation modes by processing sequences of geospatial data in a telemetric fashion. This deals with a validation problem, if a customer is in an specific transportation mode or not. In order to derive a model that is capable of such a task, we set up a web-based architecture, which has a central HTTP server and a SQLite database at its heart. Several mobile clients (we are mostly targeting smartphones) will gather geospatial positioning data via GPS satellite, connect to the central server and upload the recorded data sets. The server will hold a stack of the recorded geospatial data and analyse it in order to make an attempt in validating the used transportation modes. The validation process is based on comparing the plan data from the superordinate traveller information system, which the customer used before, with the recorded data from the smartphones. For the purpose of distinguishing between public and individual transportation and to increase the validation accuracy, it is vital to consider data sets from other travellers (as in from other sensors/smartphones). The results from the published work will be implemented in a next-generation traveling information system (nTIS), which is embedded in the Schaufenster Elektromobilität project IKT-Services in AP 7000 – Kundenorientierte Mobilität. The implementation will be tested and evaluated in the context of said project. The GPS recording capability will be implemented within the guidance and assistance functionality of the mobile application. The validation method will be part of the nTIS server application.
