7. L.I.S.T.A. – Laboratorio di Ingegneria dei Sistemi Territoriali e Ambientali Region : Tuscany (Italy) City : Pisa Residents : approximately 82.000 Surface : 7600 hectares A) The Environment in“City-Live” The Study Area

9. City-Live Population Survey Two different City Users Commuters Universe: the commuters working in the activity with more than 20 employees (source: firm direct contact) Sample: based on a spatial accessibility and homogeneity criteria Residents Universe: the total residents in the Census Areas selected (source: Statistical National Agency) Sample: a two-steps sample method Residents Commuters Pisa city centre Pisa city center Arrival points Residents Activities Commuters Activities

10. L.I.S.T.A. – Laboratorio di Ingegneria dei Sistemi Territoriali e Ambientali City-Live Population Survey Accessibility index Road Network (with one-way) Census Area centroids

11. L.I.S.T.A. – Laboratorio di Ingegneria dei Sistemi Territoriali e Ambientali City-Live Population Survey Accessibility index Gravitational Potential PG a = k j Σ j M j / d aj α where PGa = Gravitational Potential fotr the Census Area a Kj = Census Area j weight Mj = Number of emplyees in the Census Area j daj = Distance between a and j calculated on the Network alfa = distance sensitiveness We use this index to create Census Area Clusters based on homogeneous accessibility criteria
