01 / Where to look

A street is a system.

Road safety lives in relationships: a clear sign can still fail beside a hidden crossing; good pavement can still lead into a badly designed junction. Inspect the whole scene.

02 / Inspection elements

The complete field checklist.

Based on Annex IIa of the EU road infrastructure safety management directive. Search an observable condition or focus on one category.

03 / Evidence method

From a street condition
to a defensible finding.

A pin on a map is only useful when others can understand why it is there. Every finding should preserve the observation, its source, and the reasoning behind its assessment.

  1. 01

    Observe

    Locate and describe the physical or operational condition without overstating what the evidence shows.

    Geometry · date · direction
  2. 02

    Document

    Attach photographs, measurements, official data, reports, or other traceable source material.

    Source · method · provenance
  3. 03

    Assess

    Record affected users, exposure, severity, confidence, and the reasoning for each judgement.

    Risk · confidence · users
  4. 04

    Act & revisit

    Prioritise a remedy, track its status, and return to evaluate whether the condition has improved.

Absence of evidence is not evidence of safety.

Always show where and when inspection coverage is incomplete.
