One or more braking event detection computing devices and methods are disclosed herein based on fused sensor data collected during a window of time from various sensors of a mobile device found within an interior of a vehicle. The various sensors of the mobile device may include a GPS receiver, an accelerometer, a gyroscope, a microphone, a camera, and a magnetometer. Data from vehicle sensors and other external systems may also be used. The braking event detection computing devices may adjust the polling frequency of the GPS receiver of the mobile device to capture non-consecutive data points based on the speed of the vehicle, the battery status of the mobile device, traffic-related information, and weather-related information. The braking event detection computing devices may use classification machine learning algorithms on the fused sensor data to determine whether or not to classify a window of time as a braking event.

A light fixture adapted to be attached to a side of a vehicle, the light fixture including an elongated triangular shaped structure with a face viewable from, the rear of the vehicle, the face including a visual indicator electrically connected to the light fixture. The visual indicator comprises letters, words, symbols or other warning indicia to convey a visual warning to the driver of a second vehicle that is in proximity to the vehicle.

There is provided an unmanned roadside signage vehicle comprising an autonomous, semiautonomous and/or remotely controllable roadside signage vehicle for various roadside signage, emergency response and maintenance applications. In accordance with one aspect, the unmanned roadside signage vehicle comprises drive motors operably coupled to driven wheels; steering coupled to the driven wheels; a controller for controlling the drive motors and steering; at least one electronic signage board for displaying roadside signage; and a data interface for receiving at least remote control instructions, the data interface operably coupled to the controller and wherein the controller is configured for controlling the drive motors and steering in accordance with the remote control instructions.

A mobile warning device on a vehicle includes a detecting module, a driving module, a monitoring module, and a communication module. The detecting module determines whether the vehicle is unexpectedly immobile. The driving module is detachably set on the vehicle to detach and move the warning device to a specified position when the vehicle is immobile. The monitoring module is used to collect information around the vehicle. The communication module is used to transmit signals between the vehicle, the warning device, and a cloud network.

An assembly includes a lighting fixture, an optical sensor (e.g., a camera), and control circuitry. The optical sensor is configured to optically detect information printed or displayed on an object located a distance away from the sensor. The information represents an operational setting for a component of the assembly. The control circuitry is configured to use the detected information to change the operational setting of the component of the assembly, wherein the component of the assembly is one or more of the optical sensor and the lighting fixture, and wherein the operational setting is one or more of an instruction to turn on or off, an aperture and/or f-stop value of the optical sensor, and a brightness of light to be generated by the lighting fixture. According to one exemplary embodiment, the assembly is a street light and the lighting fixture illuminates a field of view of the optical sensor.
