Recent spatial analysis work for the 4th Cohesion Report Hugo Poelman REGIO-GIS hugo.poelman@ec.europa.eu

Regional analysis and indicators 15/03/2007 4th Report on Social, Economic and Territorial Cohesion Extensive overview of situation and trends in the regions of the EU Relying on regional statistical data... ... but also exploring spatial analysis methods for the production of georeferenced indicators Regional analysis and indicators

Accessibility within regions: 15/03/2007 Accessibility within regions: travel time to urban/regional centres accessibility to services of general interest travel time to transport infrastructure nodes Example: travel time to urban centres cities of more than 100000 or 50000 inhabitants Analysis example

Adaptation of the road network 15/03/2007 Adaptation of the road network - EU-27 (+ neighbours) - Crossing time of the edges EuroGlobalMap EuroGlobalMap and GISCO roads layer

Elements to estimate the crossing time of the edges 15/03/2007 Elements to estimate the crossing time of the edges - Length of the edges - Speed limit on the roads - Congestion: by overlaying the UMZs (Urban Morphological Zones) - Average slope Cost attributes CROSSINGTIME = (shape_length * slopeindex * densityindex) / (speedlimit * 1000/60) as shape_length is given in meters and speedlimit in km/h

Cost attributes: Length and speed limit 15/03/2007 The length is given by the Geodatabase (attribute shape_length given in meters because the data are projected) The speed limit is attributed taking into account the road category and a table of speed limits for the European countries Cost attributes: Length and speed limit

Cost attributes: Congestion 15/03/2007 Overlay with the Urban Morphological Zones (UMZ) to give the Density Index. Value 1; for roads outside the UMZ Value 2; for major roads and urban roads inside the UMZ Value 1.5; for motorways inside the UMZ Cost attributes: Congestion

Cost attributes: Average slope 15/03/2007 Overlay with a re-classified slope grid in order to give the Slope Index. Value 1; Slope 0-5% Value 1.2; Slope 6-10% Value 1.5; Slope more than 11% Cost attributes: Average slope

15/03/2007 Calculated with ArcGIS Network Analyst (Service Area solver), taking into account the “Crossing Time” attribute - Load facilities (e.g. cities) - Define time breaks (30 minutes and 60 minutes) - Results are polygons Accessibility

Clean the output service area polygons 15/03/2007 Clean the output service area polygons The results are polygons that do not overlap and do not exceed the land surface. Areas outside the resulting area are considered to be at more than 1 hour distance Accessibility results in 3 classes: 0-30 minutes 30-60 minutes more than 60 minutes

15/03/2007 Calculate the population that falls in the different time-distance zone for each NUTS 3 region (using grid of disaggregated population) Calculate the percentage of the total population of each NUTS 3 region located in these time-distance zones Accessibility

Analysis helps to identify more/less remote NUTS3 regions 15/03/2007 Analysis helps to identify more/less remote NUTS3 regions Results remain indicative: constraints related to data and methodology density and time stamp of road network precision of DEM selection and definition of cities (Urban Audit / UMZ centroids) population disaggregation grid versus « real » population grid Results

Approach can be tested/used in other contexts 15/03/2007 Approach can be tested/used in other contexts location of points of interest location and level of service of infrastructure nodes Enhancement of completeness, quality and timeliness of several datasets will improve results Conclusion points of interest: eg hospitals, universities infrastructure nodes: airports, importance assessed in terms of number of passenger flights
