Abstract: A traffic control system has a single light emitting area with a central location in which sensors are optionally positioned. The traffic control system is angled downward towards a roadway for improved visibility and improved aiming of the sensors. The single light emitting area selectively illuminates red, yellow, or green light to signal to the vehicle drivers when they can safely move through the intersection or when they should stop. The light emitting area presents a moving dark area or bar during display of green to convey proceed to those that are color impaired. A sweep hand as in a clock is displayed during the caution state to convey the length of time that the caution state will remain (yellow color is displayed) and also to convey the state of caution to those that are color impaired.

Abstract: A vehicle safety system includes one or more sensors interfaced to an index vehicle and a computer that is operatively interfaced to the one or more sensors, thereby the computer obtains sensor data from the one or more sensors. One or more propulsion devices are operatively coupled to the computer such that the computer controls activation of each propulsion device. The computer executes software that causes the computer to iteratively calculate a size of a safety zone based upon the sensor data and to iteratively determine if an object enters the safety zone as well as if a collision with the object is imminent. If it is determined that the collision with the object is imminent, the software causes the computer to signal one or more of the propulsion devices to emit a jet of liquid, thereby decelerating and/or changing direction of the index vehicle and/or of the object.
