FACTORS AFFECTING DRIVERS' CHOICE OF SPEED ON ROADWAY CURVES

This paper describes a survey of 207 Greek drivers who rated 14 factors of the road environment and their importance in influencing their choice of speed on interurban road curves. A comparison of responses between drivers who claimed to obey speed limits and those who did not shows that the violators gave significantly lower ratings to all types of signing and were less restricted by roadway elements in choosing their speed. Data analysis indicates that speed choice on curves can be defined by four road-environment factors: separation of opposing traffic, cross-section characteristics, alignment, and signing. Separate analyses reveal that nonviolators are mainly influenced by the signing factor in choosing their speed on curves, while violators' speed is determined primarily by the road-layout factor. These findings suggest that speed reduction, where necessary, may be accomplished through reliable signing and safe, consistent low-speed alignment. The four factors identified in this study verify findings of driver-behavior studies, demonstrating that attitude surveys can be a reliable aid in forming and evaluating relevant policies.
