Seattle startup’s bright idea: High-tech crosswalk could signal a way to improve pedestrian safety

Two years later, she’s the founder and CEO of a startup called Sensol Systems that hopes to change the way people cross the street. Sensol is creating a crosswalk that illuminates from below as a pedestrian walks across it, with lighted panels in the street that keep in step with the person who is crossing (see rendering in video below)…

The Sensol crosswalk goes beyond existing infrastructure, such as stripes on the pavement or flashing lights overhead. Modular panels are embedded in a steel frame that is installed on top of asphalt. LEDs light up when a person steps onto the hardware and pressure sensors help create the radius of illumination as the person moves.
