The Exit 65A Robotics InvenTeam is inventing MaPSS, a Micromobility and Pedestrian Safety System. This is a system of small curb-block modules that warns vehicle drivers of pedestrians, cyclists, and micromobility users who are navigating road sections with blind curves or low visibility. It incorporates radar, mesh communications, and blinking LED lights to warn drivers of the presence of another person using the road. The system activates when a pedestrian, cyclist, or micromobility user is present at that section of the road. To ensure continuous operation, a master module with cellular connectivity notifies municipal, state, or county officials if maintenance is needed. The system will reduce vehicle speeds and decrease chances of impact with pedestrians.
