摘要

The goal of this study was to investigate the required letter height for street name signs in downtown Toronto, Ontario, Canada. To be effective, a street name sign must meet two important driver needs. First, it must be conspicuous, and therefore easily detected, especially in visually cluttered urban backgrounds. High contrast between letters and sign background and consistent placement greatly improve conspicuity. Second, a street name sign must have sufficient letter height to allow drivers the time and distance needed to read the sign, make a lane change, and reduce speed prior to making turns.
