FamoS project: Bicycle models as a planning tool for reorganization of the transport infrastructure

Cities are known as complex, densely populated environments with transport infrastructure playing a substantial role. With a new policy push to shift people’s travel behavior to healthy mobility, improved cycling routes may positively alter the comfort of travelers. A model of traffic flow can help city planners to delineate spots where road rearrangement is required. By means of a simulation approach the model can imitate disaggregated movements of a very large amount of travelers in a spatio-temporal manner. Characteristics of a built bicycle network and a natural environment influence the choice of every individual to use their preferred transport mode and route within a day. Thus, dynamic assignment of people’s daily activity schedules depends on a combination of their personal attributes, along with environmental conditions and interactions. These assumptions in transport modelling are supported by an agent-based approach, which allow unpredictable patterns to emerge. 
The FFG funded FamoS project develops such a bicycle traffic flow model for the city of Salzburg in the GAMA-platform simulation environment, using the agent-based modelling approach. A project partner, the Institute of Highway Engineering and Transport Planning from the Technical University of Graz, implements a classical 4-step transport modelling technique to develop a similar bicycle demand model for Graz.

Z_GIS team awarded 3rd place at the European Copernicus Masters University Challenge

Congratulations to Martin Sudmanns, Hannah Augustin, Christian Werner, Anna-Maria Cavallaro, Dirk Tiede and Stefan Lang! The Z_GIS researchers developed and submitted a web-application to the Copernicus Masters University Challenge 2017.

The tool aims to improve the conceptualisation, planning and feasibility assessment of earth observation (EO) projects by providing information about the suitability of data for known project specifications. Projects utilising European Sentinel satellite data can be approached more efficiently, saving time and initial planning costs. The tool will also aid less experienced users of EO-data towards more efficient and targeted project planning and execution.

The interactive Web-based tool visualises and analyses the metadata of the 2+ million currently accessible Sentinel-2 images, revealing spatio-temporal variability of acquisitions that inherently influence analyses. It allows querying spatially explicit aggregated information, such as average cloud cover, average time span between scene acquisitions, time gap between cloud-free scenes, etc. Analytical maps explore specific themes (e.g. cloud cover) improving the identification of suitable study areas, or retrieval of Sentinel-2 imagery for a use-case with specific data characteristics.

For example, a project team might be interested in monitoring deforestation in Indonesia based on change detection using a time-series. With the tool, the users can select an area-of-interest and immediately retrieve relevant information about the frequency of acquisition, historic information of the average time between cloud-free acquisitions, etc.

Excellence Award for Z_GIS' Dr.Shahnawaz

Dr. Shahnawaz has been has been honoured with the ‘Excellency Award 2017’ by the Union of Geographic Information Technologists (UGIT) established at Bangalore University, India for his contributions in enhancing geospatial education, training and research in South and Southeast Asia over last fifteen years. He is Director of UNIGIS S/E Asia at the Interfaculty Department of Geoinformatics - Z_GIS, University of Salzburg, Austria and has established cooperations for Geospatial education between Z_GIS and a number of leading universities in S/E Asia and implemented a range of cooperation activities.

Dr. A. S. Kiran Kumar, Chairman - Indian Space Research Organisation conferred the award on Dr. Shahnawaz in Bangalore during the inaugural session of the 6th UGIT’s International Conference on Climate Change and Sustainable Water Resource Management – Innovative Geospatial Solutions schedule from November 9 to 11, 2017.

Congratulations!
