Disclosed is a feature for a vehicle that enables taking precautionary actions in response to conditions on the road network around or ahead of the vehicle, in particular, a traffic light, stop sign or yield sign located at the bottom of a hill. A database that represents the road network is used to determine locations where a traffic light, stop sign or yield sign is located at the bottom of a hill. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken about the traffic light, stop sign or yield sign located at the bottom of a hill. A precautionary action system installed in a vehicle uses this database, or a database derived therefrom, in combination with a positioning system to determine when the vehicle is at a location that corresponds to the location of a precautionary action. When the vehicle is at such a location, a precautionary action is taken by a vehicle system as the vehicle is approaching a traffic light, stop sign or yield sign located at the bottom of a hill.

A portable signal system for use by crossing guards, roadway construction flaggers and the like. The signal system is positioned in or alongside a roadway and remotely controllable progressively from an idle or stop mode through a warning stage and ultimately to a traffic stop mode as the signal system frontal profile greatly expands in the face of oncoming motorists. In a warning stage, the signal system presents a flashing amber light array. Following an initial warning period, articulated arms journalled on said signal system and carrying stop signal signs including red lights are swiveled outwardly to stop mode confronting motorists in oncoming traffic. A motor driven gear disk operates through pivoted drive links to control laterally outward and inward movement of the articulated arms carrying the stop signs. The system may be manually moved by handles on wheels to its operational location and anchored in place.

Disclosed is a feature for a vehicle that enables taking precautionary actions in response to conditions on the road network around or ahead of the vehicle, in particular, a traffic light or stop sign located along a curved section of road. A database that represents the road network is used to determine locations where a traffic light or stop sign is located along a curved section of road. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken about the stop sign or traffic light located along the curved section of road. A precautionary action system installed in a vehicle uses this database, or a database derived therefrom, in combination with a positioning system to determine when the vehicle is at a location that corresponds to the location of a precautionary action. When the vehicle is at such a location, a precautionary action is taken by a vehicle system as the vehicle is approaching a stop sign or traffic light located along the curved section of road.

This invention enables freeways to carry the maximum amount of traffic they can safely carry during times of heavy use of the freeway system. The invention would maximize freeway capacity by restricting the inflows of traffic and facilitating the exits from the freeway. Freeway inflows would be restricted by extensive use of metering lights and restrictions on speeds on the freeway itself. Freeway exits would be facilitated by changing traffic lights, stop signs, and anything else that restricts exits from a freeway, to allow for the free flow of traffic off a freeway. An optimized freeway system would shorten commutes, lessen consumption of gas, lower pollution, and lessen the need to build or expand freeways. Thus, it would save several billions of dollars every year.

Illuminated warning signs of familiar shapes employ back lighting through letters of smoked translucent plastic or glass. The back lighting is produced by incandescent lights or light emitting diodes located behind the letters. Thus, for example, in daylight a stop sign will appear to have black or white letters in contrast to the red background of the stop sign, but at night the letters will glow. Since warning signs provide shape to indicate the nature of the warning, the perimeter of the sign is likewise caused to glow brightly by providing one or a plurality of light pipes illuminated by lamps or a plurality of light emitting diodes. Thus, the combination of the word and the perimeter glowing brightly make clear the nature of the warning despite the sign being otherwise obscured.
