Samenvatting
A study was conducted to test the ability of subjects to estimate four different car-following distances on three types of-laned roads: segmented-lined, solid-lined, or unlined. Car-following distances were underestimated more on segmented-lined roads than on unlined roads and more unlined roads than on solid-lined roads. This finding indicates that the types of cues offered by roads affect drivers' judgements on three roads.
