Smart Cities, Volume 9, Issue 2

2026 February - 21 articles

Cover Story: This study creates an agile and reproducible methodology that maps spatial access to essential education and healthcare services across the Lazio Region (Italy) using an urban-center scale and traffic-aware routing for car and public transport. High-resolution indicators of distance, travel time and intra-municipal variability reveal strong metropolitan peripheral gradients and underserved mountainous areas, especially for specialized healthcare and secondary schools. Results are published as linked open data and explored through an interactive web viewer, enabling transparent reuse and cross-regional benchmarking with the community of Madrid to support evidence-based territorial planning. View this paper
