ChildsPlayAccessibility maps how easily children can reach play spaces, considering barriers and safe walking routes.

Natural-surveillance analyses street-view images to measure how visible streets are from nearby buildings, indicating safety and observation levels. Purpose of Tool: Natural-surveillance is an open-source Python methodology for estimating “natural surveillance” (i.e., the passive “eyes on the street” effect) at scale by analysing street-level imagery with computer vision techniques. It detects building openings (e.g., windows, doors) in street-view imagery, localizes them in

Coaccessibility measures how different age groups can reach urban amenities on foot, providing indicators of accessibility equity and age-diverse access. Purpose of Tool: The coaccessibility tool is an open-source Python library that computes demographic breakdowns of individuals who can walk to urban amenities (points of interest) within given walking time thresholds (5, 10, 15 minutes) across a street-network. It quantifies how many children, adults and elderly persons can

CTwalk Map maps 5- and 15-minute walkability, showing how different age groups can reach city destinations and highlighting local access inequalities. Purpose of Tool: CTwalk Map is an interactive web-tool which uses open-source pedestrian street-network, population-demographic and place/amenity data to map and visualise the 5- and 15-minute walking environment in cities. It estimates ➤ how many children, adults and elderly citizens can reach various destinations on foot with

CTnetwork extracts street and POI data from OpenStreetMap and computes connectivity and accessibility metrics for urban areas. Purpose of Tool: CTnetwork is a Python package for downloading street-network and Points of Interest (POI) data from OpenStreetMap (OSM) for a given city or bounding-box, and for computing network metrics on the street network (e.g., street betweenness, sinuosity, intersection closeness) as well as accessibility of POIs from different origin locations

This tool maps how easily children and adolescents can access urban green spaces from home, school, or along their daily routes. Purpose of Tool:  This tool maps the accessibility of existing urban green spaces. It allows you to calculate the accessibility of urban greenspaces by children and adolescents. It calculates accessibility not only to home locations but also to educational facilities (e.g., schools, colleges, and university buildings) and during the commute between
