Spatial analysis

Pedestrian casualties on London’s roads

2026 · Python, GeoPandas, OSMnx, PySAL, statsmodels, Leaflet

An open, reproducible analysis of every police-recorded pedestrian casualty in Greater London from 2021 to 2025: network kernel density hotspots, Getis-Ord Gi* clusters, a negative binomial model of the built environment, and drive times to major trauma centres. Includes a spotlight to explore any place and a year-by-year playback.

Pedestrian collisions in Athens

2021 · MSc Geoinformatics, NTUA · R, ArcGIS Pro, Esri Dashboards

Spatial-temporal analysis of 1,318 pedestrian collisions in the Municipality of Athens (2008–2017): hotspots, space-time cube, network analysis and Geographically Weighted Regression of the built environment, with an emergency services dashboard.

Planning and geospatial tools

Article 4 and constraints checker, Kingston

Web tool · JavaScript, Leaflet, Planning Data API, proj4

A Local Land Charges aid for the Royal Borough of Kingston upon Thames. Check a single property by address, postcode or grid reference, or upload a CSV to check hundreds at once. Each location is sent to the government’s Planning Data service and checked for Article 4 directions, conservation areas, listed buildings, tree preservation, green belt, flood zones and SSSIs. Nearby features and boundaries within a chosen tolerance (10, 25 or 50 m) are flagged as borderline, and Article 4 results are cross-checked against Kingston’s own boundaries, with an offline fallback if the service is down.

Interactive calculators

Small, research-based calculators that turn evidence into something you can try for yourself. They all live together at Reality Checks.

Reality Checks

Website · realitychecks.app

A home for all my calculators: quick, honest reality checks on everyday habits and money, each based on published evidence and clear about what it can and can’t tell you.

What’s your lifestyle costing you?

Calculator · HTML, JavaScript

How everyday habits (alcohol, smoking, activity, sitting, sleep, BMI and diet) relate to life expectancy, based on seven peer-reviewed studies and ONS life tables for England and Wales. Population averages, not a personal prediction.

What’s your coffee habit really costing you?

Calculator · HTML, JavaScript

Your yearly spend on coffee, tea and other drinks, and what that money could grow to if invested instead, with a “cut it by half” scenario.

An AI layer for the London project: questions answered by tested spatial queries rather than guesses, with the sources behind every number.
