Slow-moving maintenance operations occupying one or more travel lanes present hazards to the motoring public and maintenance workers. Flashing arrow boards are being used to improve safety during paint striping and similar moving operations. In this study, traffic performance was measured at six maintenance sites to determine the effectiveness of these boards. Approaching traffic vacated the occupied lane much sooner when a 3- by 6-ft board was mounted on the rear maintenance vehicle, but smaller boards resulted in little or no improvement over signs and flashing lights. Traffic slowed an average of 6 to 10 mph while passing maintenance operations, but the reduction did not appear to be influenced by the traffic protection devices used.
