The purpose of this utility model is the pulse signal generation that design and electronics are controlled the synchronous staff vehicles of traffic lights automatically, counting circuit, decoding scheme and pilot lamp executive circuit, in order to control the pilot lamp of three kinds of different colours as three kinds of speed of blue, yellow, purple expression, cycle constantly indicates the speed of a motor vehicle of driving vehicle changeably on highway, allows vehicle pass through the intersection in time without a break.

Three kinds of different colours orchids in the utility model, Huang, purple pilot lamp indicate vehicle to change up about 30 kilometers/hour of speed, about 15 kilometers/hour of middling speed, about at a slow speed 8 kilometers/hour respectively.Pilot lamp is installed in vehicle and drives towards the highway right side that can see in the way, intersection.The normal direction in pilot lamp front becomes with highway less than 30 ° of angles, and the vehicle driver is right-hand speed light before being clear that on about 10 meters to the 35 meters highway of pilot lamp.Therefore, every group of pilot lamp is actually the car speed at commander about 35 meters on highway beyond the pilot lamp.For example first group of pilot lamp is installed in stop line place, intersection and promptly 0 meter commands the car speed at about 35 meters outside stop line, and the 6th group of pilot lamp is installed in outside stop line 175 meters and commands about 210 meters car speeds.The method of vehicle speed indication lamp setting is, one group of pilot lamp is set, totally 6 groups every 35 meters in 175 meters scopes outside the stop line of each bar road of intersection.Each is organized vehicle speed indicative signal that pilot lamp sends and changes continuously switching time according to the fixed cycle autoelectrinic control traffic lights of intersection and send.If the time of conversion is 30 seconds to traffic lights mutually, then to open the bright cycle be exactly 60 seconds to green light, the situation that illustrates speed light indication Vehicle Speed on the road by this cycle is as follows: when the traffic lights of intersection have just been opened green light, promptly 0 of 60 second cycle second constantly, and 210 meters are sent fast signal all vehicles in commanding 210 meters with first group to the 6th group vehicle speed indication lamp on the interior road and pass through the intersection with quick 30 kilometers/hour from the stop line of intersection outside.The green light of controlling traffic lights when the autoelectrinic of intersection is bright ten seconds, in the time of also will continuing bright 20 seconds, at this moment outside the stop line of intersection 140 meters with interior the 1st group to the 4th group vehicle speed indication lamp continue bright blue look pilot lamp staff vehicles with fast by the intersection, and 140 meters later on promptly after 140 meters of the 5th group of the 6th group of vehicle speed indication lamp glassy yellow pilot lamp commanders vehicle open middling speed.When green light bright 20 seconds the time, the vehicle that the 1st group of the 2nd group of vehicle speed indication lamp still continues in 70 meters of the bright quick pilot lamp commanders in 70 meters outside the stop line of intersection changes up speed by the intersection, in 70 meters to 140 meters promptly the 3rd group of the 4th group of vehicle speed indication lamp then brilliant violet look pilot lamp staff vehicles change down speed.140 meters is later on that the 5th group the 6th group vehicle speed indication lamp glassy yellow pilot lamp staff vehicles opened middling speed.When green light has just transferred red light to the 1st group to the 4th group vehicle speed indication lamp transfer to entirely vehicle in 140 meters of the bright commanders of pilot lamp at a slow speed open with the green light of following one-period of waiting for the intersection traffic lights at a slow speed under steam bright, thereby realize that vehicle does not pass through the intersection with stopping over.The following describes when road crossing traffic lights open send out a warning after, on this highway the vehicle speed indication lamp staff vehicles with in, situation about waiting under steam at a slow speed.Commander's situation with red light explanation in bright back ten seconds pilot lamp is as follows, at this moment outside stop line in 70 meters the 1st to the 2nd group of pilot lamp continue brilliant violet look pilot lamp staff vehicles to travel at a slow speed, and in 70 meters to 140 meters the 3rd group the 4th group bright orange lamp staff vehicles of vehicle speed indication lamp to drive at moderate speed, beyond 140, the 5th group of then bright blue look pilot lamp staff vehicles of the 6th group of vehicle speed indication lamp changes up speed and travels.When red light bright 20 seconds the time, this road continues brilliant violet look pilot lamp staff vehicles with interior the 1st group of vehicle speed indication lamp for 35 meters and changes down speed, the the 2nd to the 3rd group of vehicle speed indication lamp glassy yellow pilot lamp staff vehicles travels for 15 kilometers/hour with middling speed in 35 meters to 105 meters, and 105 meters outer the 4th group of bright blue look pilot lamp staff vehicles of later vehicle speed indication lamp travel with 30 kilometers/hour speed.In concrete one-period each constantly the bright situation of vehicle speed indication lamp see Table the routine moment that goes out of 1 right side institute.As seen, the command signal of the utility model vehicle speed indication lamp is one by one to moving forward along with the time duration after the unlatching of fixed cycle robot traffic lights.And, 140 meters with the pilot lamp that must be provided with three kinds of colors in the interior the 1st to the 4th group of vehicle speed indication lamp indicate respectively soon, in, slow three kinds of speed of a motor vehicle, the pilot lamp that the 5th group the 6th group vehicle speed indication lamp only need be provided with orchid, yellow two kinds of colors beyond 140 meters indicates respectively soon, in two kinds of speed of a motor vehicle.The 6th group of vehicle speed indication lamp is that last group pilot lamp is located at higher position with higher iron, after the direction omnidirectional of lamp, 0 ° of angle, making in the end, this group lamp interior car of a segment distance later on far away is commanded by it, when this group pilot lamp bright orange lamp, vehicle does not just quicken not slow down yet and allows car slide not expend fuel oil.Car quickens to change up speed when the bright blue lamp of last this group pilot lamp, when the 6th group of lamp become amber light when reaching be 210 meters away from intersection fast as the distant place car, promptly miss also not serious 210 meters in addition of last blue lamp of organizing lamp, can in these 210 meters, regulate the speed of a motor vehicle and make car, again with passing through that the speed of the best does not stop to economize most gasoline.If the road between two crossings is shorter, just adorns several groups of pilot lamp and just adorn several groups of pilot lamp according to Lu Changneng.Three kinds of speed of three kinds of color pilot lamp indications and not really strict in the utility model, it also can indicate the operation of three kinds of drivings roughly, and blue lamp is for quickening (step on the gas) purple lamp for slowing down, and amber light is an art skating.In addition, if the primary and secondary road junction traffic lights opening time do not wait situation, then will be according to the vehicle speed indication lamp that reduces traffic lights switching time or increase on the primary and secondary road.Can realize the vehicle control by the intersection without a break like this, equally.After realizing the speed of vehicle ' on the utility model control road, pass through the intersection with the intersection vehicle relatively with more than 30 kilometers/hour speed, 22 meters calculating of vehicle center spacing, 22 vehicles of two common mistakes of relative direction in 30 seconds then, continuous vehicle by the intersection can reach 6.3 ten thousand in one day 24 hours, per hour about 2640, the service efficiency of highway will improve greatly, and social benefit of the present utility model and economic benefit are clearly.
