A user-controlled portable traffic control system comprises one or more traffic signal units and a wireless handheld remote-control unit. Each traffic signal unit provides instruction to approaching motorists via a segmented backlit display consisting of first and second message panels. The wireless handheld remote-control unit allows a user to communicate commands to the traffic signal units via a transceiver circuit. Additionally, the handheld remote-control unit includes an interface indicating system status information via a plurality of indicator lights corresponding to the traffic signal units.

Each traffic signal unit is housed in a two-part collapsible rigid outer case with a mounting handle allowing for ease of transport and a versatile means of both mounting and transporting the system.

Embodiments of a safety alert device and associated methods are disclosed. In one embodiment, the safety alert device includes a processing element and an image sensor in operative communication with the processing element. The processing element is configured to receive image data of a region of interest. The processing element determine a presence of a moving object in the region of interest based on the image data. The processing element is configured to identify a presence of a person in the region of interest based on the image data. The processing element determines a likelihood of a collision between the moving object and the person, and generates, based on the likelihood being above a threshold, an alert adapted to warn the person of the likelihood of the collision.

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.
