Road risk at a glance

Plain-language figures summarising where collision risk is highest across the Open Road Risk study area.

Figures summarising the main outputs of the risk model, without the modelling detail. The map is exposure-adjusted: it reflects risk given traffic, not simply where the most collisions happen. Full methodology and diagnostics are on the Stage 2 model page.

The map has three views: merged named reporting areas, equal-size 10 km grid cells, and the same grid with reporting-area boundaries.

Traffic volume

The map below uses the same geography and controls, but colours areas by median estimated AADT rather than modelled risk.

The named-area view uses a merged reporting geography so compact urban authorities remain legible. A small Fenland boundary gap in the source polygons is joined into Cambridgeshire and Peterborough. The grid view uses equal-size 10 km cells and omits cells with fewer than 20 scored links.
