Abstract
An alert system and method comprising at least one alert beacon having one or more sensors (e.g., LiDAR sensor). The alert beacon further including a processor operable to poll the LiDAR sensor for a predefined number of beta readings in response to receiving an initial reading from the LiDAR sensor indicating a vehicle is within a predefined distance away from the alert beacon. The processor further being operable to calculate an average distance and an average velocity for the vehicle in response to receiving the predefined number of beta readings when the vehicle is within the predefined distance from the alert beacon. The processor also being operable to activate an audible alert and a visual alert when the average distance is below a distance threshold and the average velocity exceeds a velocity threshold in response to calculating the average distance and the average velocity.
