Traffic light system. Here's my idea for a modern traffic light control system. > 1 the main part of the system would be highly sensitive motion detectors that would measure the speed of the approaching vechile, count how many vechiles are approaching. and also the mass of the vechile. This would allow it to ascertain if it where a large truck and give it preferential status for right of way. These would be mounted atop of the lights or further up the road to allow east detection. 2>If a detection system is not availible to detect the mass of a vechile then scales could be built into the road to measure the weight of the approaching vechile , again giving prefential treatment to heavy vechiles, enabling them to continue umimpeded. 3>.A highly sophisticated computer would calculate all the gathered information , changing the lights to keep the bulk of traffic flowing . 4> As a built in saftey system's it would used the data of approaching vechiles and determine if a collision is imminent. (in the scenario all lights would immediately flash red ,warning both drivers to stop and yeild , preventing a collision). Also part of the detector would sense emergency vechiles approaching and automatically give right of way to them. (This would require emergency vechiles to have a switched sensor emitting a pulse only in emergencys.) 5>.All the traffic light sytsems would intergrate into a main frame computer that uses gathered information to constantly improve on the systems timing and accuracy. This would be relayed via satellite straight to the main computer , giving a live image of current traffic conditions. (this can then be relayed to onboard GPS systems of other cars to avoid congested areas. 6>.The enviromental impact would be huge , saving fuel, time, congestion for all drivers , not limited to new hybrid vechiles. 7>.The current system in use today dates back to the 1950's with a trigger wire under the road , connected to a timer box for the It requires the vechile to come to a complete stop before triggering the lights if they are currently red. This system is far outdated and needs a modern revamp to meet todays world. This system would save up to 5-10% on fuel savings for drivers , quickly paying for itself. The profit potential for producing a modern traffic light system would be huge with millions of intersections around the world in dire need of a quick fix to help solve , congestion, pollution,rising fuel costs.
