This project aims to create a visibility scale that allows bikers to understand how visible they are depending on their helmet color and light features. Enhancing biker safety by understanding visibility is essential for reducing biker accidents and creating a greater feeling of safety surrounding environmentally friendly modes of transportation. Currently, the only measure of biker safety on city streets is the number of crashes. This measure is retroactive; by the time that safety is measured, the damage is already done. In our project, we will be leveraging eye tracking technology to measure how quickly a driver fixates on a biker wearing helmets that vary in color and technology. By running these experiments we can compare how visible different helmet features are to a driver. This visibility scale will create a proactive measure of safety for bikers and will inform bikers of their visibility levels before they leave the house for a ride.
