The Stridel Access Index.

A destination-accessibility index — how easily a place reaches everyday destinations on foot, today; a walkability index tomorrow. Here is where it came from, where it is, and where it's heading.

01

Where it came from

  1. The question

    How walkable is a place, really? Public accessibility statistics stop at the local-authority level — too coarse to see the street.

  2. A finer grain

    Stridel scores accessibility at the grain of a neighbourhood rather than a whole borough, so the texture within a place becomes visible.

02

Grounded in evidence

  1. Tracks how people actually move

    The index reflects real walking-to-work behaviour recorded by ONS Census 2021 — a rank correlation of ρ ≈ 0.67, not opinion.

  2. Honest about equity

    The index's relationship with deprivation is measured and disclosed on every view — an equity audit most tools don't publish about themselves — shown with a colour-vision-safe palette, never red-amber-green.

Where it is now

A live index across UK local authorities — a destination-accessibility index at MSOA grain, growing as new areas clear validation. Each city reads on its own scale; there is no cross-city league table.

Where it's heading

  1. The lived street

    Pedestrian-environment quality — pavements, crossings, severance — the part of walkability the access-and-connectivity index doesn't yet capture.

  2. Independent validation

    A blind field audit across multiple cities, with independent raters — what it takes to call it a walkability index, honestly.

Partner with us

Local authorities — with access to your data (pavement condition, crossings, network detail), the Stridel Access Index becomes a true walkability index for your area, not just an accessibility one. We're looking for LA partners to build it together.
