| 摘要： | After a long period of consultation and assessment the Federal Highway Administration announced the standards required in maintaining minimum levels of retroreflectivity for pavement markings to all roads open to public travel in the United States. The US division of lrish firm RetroTeck (Reflective Measurement Systems) says it welcomes the FHWA's update to the Manual on Uniform Traffic Control Devices and it should play a key role in reducing transportation-related fatalities and serious injuries. The ruling will also help to support the operation of Autonomous Driver Assisted Systems (ADAS) that are increasingly dependent on high quality longitudinal pavement markings to operate correctly. RetroTek said it would "highly recommend" that US road agencies start the planning process now to address how they will monitor and maintain pavement markings to the new standards for minimum retroreflectivity levels. "We believe the most efficient solution which maximises data collection and minimises disruption to road users is the RetroTek-D mobile retroreflectometer system. This will enable road authorities to get accurate retroreflectivity measurements across the full lane width in one pass, day or night, minimising survey time and fuel costs. |
