Abstract

Transverse pavement markings were placed ahead of a sharp curve that had a history of high accident rates. Before-and-after studies of speed and accidents were conducted. The markings were placed so that drivers who failed to slow when approaching the curve would see the transverse lines on the pavement at an increasing rate. The spacing of lines was intended to create an illusion of acceleration that would cause the driver to slow. The results indicated that pavement markings can be an effective speed-control measure and reduce accidents. At the single site studied, the obedience of drivers to this type of hazard warning was more effective than signing alone. Further use of this type of marking may be warranted at locations at which excessive speed contributes to accidents. The length or roadway marked in this trial was 247 m (810 ft). Although the striping tape performed satisfactorily, painted lines could be used as an alternative.
