Cross Walk Safety: Making roads safer one device at a time


In 2019, there were 972 pedestrian-related fatalities in his home state of California alone (

Satyam Goyal, a senior at American High School, is working to reduce that number by designing and deploying a device that solves the issue of crosswalk safety in uncontrolled intersections. Goyal created what he later called “the smart crosswalk sign” as part of his Eagle Scout Project for Boy Scout Troop 273. The first two of Goyal’s signs were installed outside Ardenwood Elementary School and have since been used by several young pupils and their parents.

The device works on radio frequency, and both signs have a receiver and a timer. Pedestrians can press the buttons on two transmitters positioned on opposite ends of the road. When someone presses the button, the transmitter activates the flashing light, alerting drivers that there is a pedestrian crossing. To eliminate the requirement for people to press the red button, Goyal wants to investigate the idea of employing Artificial Intelligence and Computer Vision to identify pedestrians approaching, making crosswalks smarter and safer for both cars and pedestrians.

Recalling that there aren’t always enough volunteers to aid, causing drivers to navigate crosswalks alone. Goyal underlines the need of having an option that does not endanger another person’s life and may be employed in the event of a volunteer scarcity.

This technology not only improves the safety of persons crossing streets, but it is also cost-effective. Goyal built the device for only $200, but similar infrastructure might cost tens of thousands of dollars to build.

The mission does not stop at installing the gadget in Goyal’s hometown; it also includes boosting road safety awareness. Goyal recalls how he and his boy scout troop held a kiosk during “Maze Day,” a school registration day one week before school starts, to increase awareness of traffic and pedestrian safety.

They took a similar technique for “Back to School Night,” but added phrases with one-time safety recommendations like “One text or call can spoil it all.” attempting to communicate important messages.

Goyal’s major goal for this year is to install this device at five schools. He eventually would like to offer the device to the entire Fremont Unified School District.
