Description
These devices are yellow warning lights placed either on poles or mounted in the pavement at crosswalks to alert motorists of a pedestrian crossing. The flashing lights can be installed so that they are actuated by pedestrians at a crosswalk using a push button.
Issues Addressed
Applications
Advantages
-
Pedestrian's actions are more visible and predictable for motorist.
-
More effective than painted crosswalks.
Disadvantages
-
Pedestrians may have a false sense of security; pedestrians may falsely assume motorists will see them and yield.
-
Relies on driver attention and compliance. May not slow all drivers.
-
Relatively expensive to install.
Evaluation Considerations
-
Not as effective for crossings with pedestrian traffic volumes less than 100.
Design/Installation Considerations
-
Flashing lights' brightness must be able to adjust to amount of sun light (Ex. amber light more intense during the day, less intense at night).
