Abstract

Some important aspects of human performance of relevance to the traffic engineer are reviewed in this paper. These aspects include information processing, visual characteristics and information needs. Practical guidelines are presented on how these considerations might influence traffic design and control. Information aspects discussed include the driving task, a model of the latter, expectancy, reaction time, short-term memory, and hysteresis effects. Visual characteristics aspects discussed include visual field, eye and head movement, illumination, and visual handicaps. The key needs of road users in relation to traffic control information are discussed and include conspicuity, legibility, comprehensibility, credibility, and delineation.
