RECOMMENDED PAVEMENT MARKING SEGMENT TO GAP RATIO CHANGED

The Federal Highway Administration has announced that the FHWA now recommends the use of a segment to gap ratio of 1:3 for broken line longitudinal pavement markings. The next revision of the Manual on Uniform Traffic Control Devices (MUTCD) will provide the recommended segment to gap ratio of 1:3. For rural highways, a 10-foot segment and 30-foot gap is recommended. Previously, section 3A-6 of the MUTCD provided that a broken longitudinal pavement marking is formed by segments and gaps usually in the ratio of 3:5 and that on rural highways, the commonly used standard is 15-foot segments and 25-foot gaps. Recent studies sponsored by the FHWA indicate that a shortened line segment will not reduce the effectiveness of pavement markings while significntly reducing the amount of marking materials used. /Author/
