Uncontrolled crosswalks are crosswalks that cross the roadway at a location where no stop or signal control exists.

Di scu ssi on Improve sight lines: The desired driver action at an uncontrolled crosswalk varies based upon the presence or absence of a pedestrian. In a field study of midblock crosswalks, the addition of yield lines and "Yield to Pedestrians" signs increased the likelihood that drivers look to the right for crossing pedestrians ( 4 )

METHODS TO INCREASE COMPLIANCE AT UNCONTROLLED CROSSWALKS Introduction Methods to increase compliance at uncontrolled crosswalks refers to treatments that improve pedestrian safety. These improvements are realized through safer pedestrian behavior and increased compliance with crossing treatments.

Maintaining safe speeds is particularly important in school zones for multiple reasons: (1)

SIGHT DISTANCE CONSIDERATIONS FOR URBAN BUS STOP LOCATIONS Introduction Sight distance considerations for urban bus stop locations refers to sight line issues that stem from the placement of urban bus stops. Bus stop placement and design are dependent on a multitude of factors including vehicle delays, bus delays, pedestrian waiting areas, cost, safety, and others.

Discussion One of the factors that results in bus collisions with vehicles or pedestrians is the lack of adequate sight distance or sight lines. A review of pedestrian safety research (1)
