Intersection Lighting
Adding intersection and / or pedestrian-scale lighting at intersections increases the visibility of all road users . This countermeasure is most effective at reducing or preventing collisions at intersections at night or in lowlight conditions . When lighting pedestrian crosswalks , it is helpful to use lighting analysis to avoid designs that inadvertently introduce glare or backlight pedestrians , making it hard for motorists to see them .

Median Guardrail
The installation of median guardrail is most suitable for use in traversable medians having no or little change in grade and cross slope . While these systems may not reduce the frequency of crashes due to roadway departure , they can help prevent a lanedeparture crash from becoming a head-on collision .
