Use of Chevron Patterns on Traffic Control Devices in Work Zones (Abridgement)

The objectives of the research were to select the most effective design for the chevron pattern and to evaluate the effectiveness of selected chevron designs under road conditions as compared with currently used designs. In a supplemental test, the effectiveness of the New Jersey concrete barrier was compared with that of the channelizing devices studied. In general, the selected chevron designs were preferred over the currently used patterns. Driver response was found to be not strongly dependent on the channelizing device employed in the taper. A supplemental taper of channelizing devices was found effective for use with the New Jersey concrete barrier.
