LED-Outlined Crosswalk System
Approach and Considerations
In late 2005 an Iowa State student was struck by a charter bus while crossing a street on campus. This incident may have been avoided if there had been some sort of warning system to alert the driver of the bus that there was a pedestrian crossing the street. The objective of this project is to produce crosswalk signs capable of grabbing the attention of motorists, and in doing so, reduce the chance for an accident. The crosswalk signs will be the standard diamond crosswalk signs with LEDs mounted in each corner. These LEDs will flash to attract motorist’s attention to the crosswalk. Also, the LEDs will flash during specified high traffic times throughout the day and also be available “on demand” through the use of a pushbutton at the signs.

Preservation of human life is of the utmost importance. Whatever can be done to further this cause should be effectively implemented. It is the goal of this design team to do just that. A crosswalk sign with flashing LEDs shall be designed and produced with the purpose of attracting motorist’s attention to the crosswalk and to the pedestrians crossing the street. Once the signs are in place, the design team feels that pedestrian safety shall be increased, and the likelihood for motorist-pedestrian collisions shall be greatly reduced.
