Abstract
Conventional highway lane markings are ineffective at night, particularly when the pavement is wet. There is a recognized need for a system that is effective at night under wet conditions and where there is no reduction in current daytime standards. To be effective at all times the system must maintain wet-night retroreflective properties while resisting deterioration caused by snowplows, studded tires, sand and salt applications, and lane changing maneuvers by traffic. This project tested a system of low-profile lane markers developed by Battelle Columbus Laboratory under contract with the Implementation Division of the Federal Highway Administration.
