Abstract
Roadside photographs taken in conjunction with an anthropometric survey were used to determine the distribution of eye heights of British car drivers. Drivers were sampled on the roads used in the traffic census carried out by TRRL, covering urban and rural sites in England, Scotland and Wales. Comparison with estimates of eye heights made in 1962 suggest that there has been a considerable decrease in eye height in the last fifteen years. The present united kingdom eye height criterion adopted for geometric design corresponds to the 4th percentile eye height of the drivers sampled.
