Work out pedestrian level of service instantly with clear inputs, formula shown and shareable results.
Pedestrian level of service is judged on space per person, derived from unit flow rate divided by walking speed. Effective width matters because pedestrians keep clear of walls, kerbs, street furniture and shop frontages, so a three metre footway may offer only 2.4 metres of usable width.
Unit flow rate
People per minute per metre = flow / effective width
Space per pedestrian
Space = walking speed / unit flow rate, with speed about 75 m/min
People per minute per metre = flow / effective width. Pedestrian level of service is judged on space per person, derived from unit flow rate divided by walking speed.
A shopfront takes about 0.6 m for window shopping, a kerb 0.45 m, street furniture 1.0 m or more. On a busy high street half the nominal width can be unusable.
This calculator takes 3 inputs: Pedestrian flow, Walkway width, Width lost to obstructions and edges. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
