280 Transportation Research Circular E-C058:9th National Light Rail Transit Conference Active Safety Treatments An approaching train automatically activates these devices. These systems may consist of automatic gates, flashing light signals, traffic control signals, warning signs, audible signals, and other active warning devices. LED Flashing Train Warning Signs TriMet light rail operations has found that flashing train signs are an effective warning device for both pedestrians and motorists. Figure 9 depicts such a device in a pedestrian application. To warn motorists of an approaching train at traffic signal controlled intersections, consideration should be given to incorporation of LED flashing train signs on traffic signal mast arms or poles in the following situations: • Left turns by motorists are permitted across the trackway, • Cross traffic motorist volumes are high, • Line of sight obstructions limit motorist ability to see oncoming trains, or • There is a high volume of slow moving or turning truck traffic across tracks. TriMet has installed LED flashing signs overhead at several locations for motorists. Examples are 10th and Washington in Hillsboro, 18th and Salmon in downtown Portland, and 82nd and Airport Way. On Interstate MAX, which is currently under construction, the signs have been incorporated into the design at all left turns across the trackway, at cross streets with high volumes of traffic, and at certain obstructed crossings. At pedestrian crossings at intersections equipped with traffic control signals, pedestrians cross the light rail tracks in response to standard “Walk” and “Don’t Walk” signal indications. Generally, a pedestrian LED flashing sign and audible warning device is not required in the traffic signal controlled environment.
