Overview
KCDC engaged TTAP to assess pedestrian safety across school zones in the district. The work combined safety engineering, safety audit, traffic engineering and civil design — focused on pedestrian crossings near schools and the kerb-ramp infrastructure feeding them.
What we did
- Audit of zebra crossings against current standards — bar marking width, bar marking gap width, bar marking bar length, mid-line widths, no-stopping line distances, lighting, beacon-pole and warning-sign compliance
- Audit of associated kerb-ramp infrastructure — ramp width, ramp gradient, ramp crossfall, channel gradient, landing dimensions, flare gradient, warning tactile depth and width, directional tactile length
- Risk-rank assessment and prioritisation of non-compliant locations
- Civil design of recommended upgrades

Outcome
The audit produced a defensible, school-by-school prioritisation of pedestrian-safety upgrades for KCDC’s forward maintenance and renewal programmes — feeding directly into the council’s Low Cost Low Risk funding bids and the broader Speed Management Programme.
