| − | | |
| − | ===Performance Expectation===
| |
| − | Long lines, including striping in rumble strips, shall look good during the daylight, provide adequate retro-reflectivity at night and display adequate visibility during rain.
| |
| − | | |
| − | ===Performance Measures===
| |
| − | Visual inspections and retro-reflective measurements will be conducted on randomly selected tenth-mile segments in the spring and fall to determine if the stripes look good and are performing as intended.
| |
| − | | |
| − | ===Performance Objectives===
| |
| − | 95% of the striping shall not appear damaged or missing to the driver at a distance of 150 ft. from the vehicle. 95% of the stripe should closely match the original stripe location. Minimum requirements of 150 mill candelas per square meter per lux for white and 125 mill candelas per square meter per lux for yellow. Markings that have failed shall be re-striped within 30 days of detection or no later than the following Memorial Day weekend if damaged by winter operations. | |
