Alerting systems for construction workers
Construction workers on roadside construction sites are frequently in danger of being struck by passing cars. These workers perform physically demanding tasks in all weather conditions and sometimes in areas where appropriate signage is limited or not present. This project investigated some options for alerting them of impending danger. The source of the alert can vary, one example is this.
The shoulder pad is an add-on designed to provide shoulder protection and a suitable place to deliver audible, haptic and visual alarms. A clamp applies pressure when activated, making it suitable for wearing over winter clothing.
The smart safety vest has vibrating motors around the collar and chest. This place was chosen for convenience of placement and improved likelihood of being noticed. There are a pair of speakers placed near the top of the shoulders in order to minimize the distance between them and the ears. Warning LEDs were placed on the front of the vest.
We compared the reaction time of participants using different modalities in a small study.
Also participated in this project: Kristen Hines, Namitha Somasundaram and Thomas Martin.
