| Talking GPS Navigation Speed Limit Additive 
If you add a transmitter to all posted speed limit signs or areas for a certain road, Highway, or freeway (speedway), or just add that information to the GPS navigational equipment in your vehicle, you could move onto a road where the signs might be behind you or not visible at the time you pass the sign post then, we would have happier law enforcement officers, know the speed limits and less accidents and speeding tickets, keeping your auto insurance costs lower and yourself safer and more informed when on roads when you just don't know how fast you can go. Maybe we could add this technology to auto manufacturing and have it transmitted just above our speedometers to help keep track of our own speed.Speeding tickets are the number one reason a person will be stopped for and is the biggest problem for us and speeding endangers pedestrian traffic crossing dangerous or busy roads. All around safer driving for all. All the speed limits could be transmitted and spoken to the person in the automobile through a small speaker installed by the manufacturer, through the GPS Speakers, or the speed limits could come across on one of your radio stations with local, state, and/or federal law enforcement traffic and road condition commercials between speed limit transmissions. They could add any additional information to that channel about the road or a commercial of any kind they wish.Reward: Credit

| Coordinated traffic signals that adapt to traffic flow
There's an accident here on I-5 south and cars flock to side streets to avoid the delays. One lane of the interstate is blocked and miles and miles of backup occurs. But then, the side streets become congested too, then the side side streets etc.The problem is that the traffic signals on the side streets do not adapt to the radically changed traffic pattern. Sure, some signals are programmed by the hour of the day; others are set not to change until a car arrives on the "side" street. But what about when there's an accident? Sometimes you see a cop out there directing traffic through the lights just to get things going.I believe that the traffic lights can adapt to the traffic by two simple additions to the local control systems. One implements a car counter to detect traffic (backup and flow rate, etc). The other implements a multi-light synchronization so the entire system can adapt in coordination. It's really a simple concept - maximize the flow of cars through an intersection and compensate for nearby congestion by knowing which intersections will be receiving exiting traffic and which will be providing incoming traffic. (Optimal flow isn't local to one intersection only yet can be reasonably achieved within a small radius of nearby intersections, cooperating with each other.)The car counter technology could be: radar based units, "photo camera" add-ons, feedback from pressure sensitive pads in the road, those tubes they put down to monitor traffic, or even car based beacons (eventually). If you have a cell phone today in your car, you have a car based beacon already. The interconnection of traffic signals / systems could be implemented easily with secure, short burst digital wireless technology. The control algorithm would be a blast to write.Basically, in my drive home, when the freeway is clogged and people exit to bypass the accident via side-streets, the intersections that are passed through in the bypass route are adjusted (even slightly) to allow more traffic in the most travelled direction. The system and the traffic would seek equilibrium - a balance in traffic flow throughout the whole network of roads. After the congestion dissipates, the system could return to "best guess" settings derived over long term pattern analysis.This wouldn't have to be done everywhere - but instead could be applied in areas of high "rush hour" congestion and more-than-typical re-routings.Reward: I just wanna get home in a reasonably predictable time.

| Bike Awareness Sensor
How many times do we see bikers hurt or killed in accidents with cars? How many times has the reason been "I just didn't see them." from the car driver?We all suffer from not being aware enough at times when on the road...maybe when tired, or when bored, driving down an endless motorway.My idea is that there are sensors in the rear bumper of the car that check for items of bike size. It could either be done on size, or have bikes fitted with a partner sensor, so that when the signals meet, a light and warning beep sound in the car, to alert the driver that there is a biker behind them and to watch out as they will more than likely over / undertake them soon. If there were 2 alert lights in the dashboard of the car, maybe under the indicator lights, then the corresponding side would illuminate, so that the driver would know from which side the bike was approaching.Reward: 100% credit and the lives of many bikers saved.
