ENGINEERING COUNTERMEASURES TO REDUCE RED LIGHT RUNNING Introduction Red light running refers to drivers' entering a signalized intersection when a red light is being presented (1)
|
From page 87... ...
Discussion Several driver-related factors and driver behaviors are relevant to red light running and countermeasure selection. Campbell, Smith, and Najm (3)

RESTRICTING RIGHT TURNS ON RED TO ADDRESS PEDESTRIAN SAFETY Introduction This guideline describes approaches for implementing restrictions on right turn on red (RTOR) movements with the objective of reducing conflicts between pedestrians and right-turning vehicles.
|
From page 89... ...
Discussion With regard to conditional RTOR restrictions, restrictions based on certain times of day (time-restricted) and those based on the presence of pedestrians (pedestrian-restricted)

HEURISTICS FOR SELECTING THE YELLOW TIMING INTERVAL Introduction The yellow timing interval refers to the duration of the yellow signal indication; the yellow timing interval is also referred to as the "yellow change interval" in a number of sources. The yellow signal warns oncoming traffic of an imminent change in the right-of-way assignment (1,2)

Discussion Driver behaviors relevant to the selection of a yellow timing interval have been studied by the transportation research community for many years. Tijerina, Chovan, Pierowicz, and Hendricks (6)

Discussion Curb ramps: Aligning themselves with the crosswalk and staying within it are some of the biggest challenges that visionimpaired pedestrians face at intersections. One study found that only 66% to 75% of pedestrians started within the crosswalk, started from an aligned position, traveled within the crosswalk, and ended within the crosswalk (2)
