A vehicle warning sign comprises: a reflective material for at least visible light; and at least one of (i) a heating element for detection by a thermal sensor or (ii) a corner reflector for detection by a radar, the corner reflector oriented substantially in a common direction with the reflective material.

A traffic safety sign assembly for guiding traffic around a vehicle parked on a shoulder of a roadway includes a sign that is positionable on a vehicle that is parked on a shoulder of a roadway. In this way the sign is visible to oncoming traffic on the roadway. Arrow indicia are printed on the sign to direct oncoming traffic away from the vehicle. A plurality of sign light emitters is each integrated into the sign to emit light outwardly from the sign. In this way the sign light emitters enhance visibility of the sign for the oncoming traffic. The plurality of sign light emitters is strategically arranged on the sign to indicate a preferred direction of travel. In this way the sign light emitters visually communicate the preferred direction of travel to the oncoming traffic.

A safety warning sign, when not in use, is rolled and stored inside to case, and in the event of emergency, when a driver opens the trunk and then opens the case by pulling a cover with a finger while the case is attached and affixed to the edge of the trunk by means of a magnetic body of an attachment member connected to the case, the safety warning sign stored in the form of a roll inside the case is, simultaneously as the case is opened, automatically spread open by its own weight (gravity) and deployed, thus allowing the driver, even in the state of panic from an accident, to easily and rapidly install the car safety warning sign and quickly escape to safety.

An apparatus for mobile machinery includes a sensor module configured for detachable fitment to mobile machinery, and a control module configured to interface with a control system of the mobile machinery. The sensor module includes an orthogonal sensor arrangement for sensing obstacles in three-dimensional space, an orthogonal indicator arrangement configured to provide a gradient proximity indication of an obstacle, and a wireless transceiver arranged in signal communication with the sensor and indicator arrangements. The control module includes a control wireless transceiver for communicating with the wireless transceiver of the sensor module, and a processor in signal communication with the control wireless transceiver, the processor configured to program, via the wireless transceiver of each sensor module, the sensor and indicator arrangements and with predetermined thresholds of obstacle proximity. If a sensed obstacle proximity exceeds a maximum threshold, the processor overrides the control system to facilitate situational awareness of an operator.

An emergency vehicle notification system, including at least one illumination device disposed on at least a portion of a traffic light to illuminate at least one illumination setting, and a control unit removably disposed within and removably connected to an emergency vehicle to change the at least one illumination setting in response to changing an operation status using an alert signal.

In some embodiments, an apparatus, comprises an unmanned vehicle configured to be disposed with a vehicle and a processor operatively coupled to the unmanned vehicle. The processor is configured to receive a first signal indicating a stop of the vehicle without a user request and a second signal indicating a location of the vehicle. The processor is configured to determine, based on the location of the vehicle, a target location in a pre-defined area surrounding the vehicle. The processor is configured to send a third signal to the unmanned vehicle to instruct the unmanned vehicle to move to the target location to alert other vehicles via a warning regarding occurrence of the stop.
