9. Datasets and data processing

10. Datasets – socio-economic Table UV31 (Resident population) Table UV76 (Workplace population) Census output area Data for population aged 16 to 74 by their socio-economic classification Classification of occupation Ordnance Survey Address Layer 2 Points Address Layer 2 is derived from the Royal Mail postal address file (PAF), whereby each address is allocated a unique reference and national grid reference. Functional activity land uses Table UV39 (Resident population) Table UV37 (Workplace population) Census output area Usual population aged 16 to 74 and their method of travel to work. The method of travel to work is for the longest part, by distance, of the usual journey to work. Method of travel to work Ordnance Survey Meridian & Address Layers 2 Polylines and points Railways, Stations (Tube and Rail), A, B and minor roads, motorways and car parks Infrastructure 2001 Census: Special Workplace Statistics Census output area Contains journey-to-work flows within and between output areas in England Commuting patterns Table KS17 Census output area Car or van ownership per household Car Ownership Source Areal Unit Description Data

11. Datasets – space syntax Segments angular choice is : Measures the relative straightness of each segment from all other segments in the system. It calculates the number of times each segment falls on the shortest path between all pairs of segments where shortest path is that of least angular deviation - Red lines (high values) indicate greatest potential through movement. - Blue lines (low values) indicate lowest potential through movement.
