Embodiment
Below in conjunction with embodiment, the utility model is described in detail.
As shown in Figure 1, the utility model system comprises a plurality of suggestion speed display devices 1 and a signal conditioning package 2.Wherein, traffic lights Control Network 3 state that vehicle front traffic lights 4 is current, the time Changing Pattern of traffic lights flow to signal conditioning package 2, the information of 2 pairs of inputs of signal conditioning package is calculated, calculate and be fit to the velocity range of vehicle by its junction ahead, and choose realistic velocity range and flow to traffic lights Control Network 3, by traffic lights Control Network 3 velocity range is sent to suggestion speed display device 1 again and show.Can show a plurality of different suggestion velocity ranges on the suggestion speed display device 1 of the present utility model simultaneously, and out of Memory such as wagon flow prompting.
As shown in Figure 2, the suggestion speed display device 1 of the utility model system is arranged on road or bridge both sides, and the distance of the traffic lights 4 corresponding with its place ahead is d.The position of suggestion speed display device 1 can be provided with flexibly according to factors such as the length of road, the daily traffic volume of advising speed display device 1 place road and average speeds, its number can be configured according to actual needs, and its direction can be according to keeping straight on and the proportionate relationship of bogie car flow etc. is optionally installed.In the present embodiment, suggestion speed display device 1 can adopt existing various display device, is convenient to driver's observation and gets final product to best suggestion speed, does not limit at this.
Preset the renewal frequency between the corresponding traffic lights 4 of suggestion speed display device 1 in the signal conditioning package 2 of the utility model system apart from d and suggestion speed display device 1 displaying contents with its place ahead.Signal conditioning package 2 is according to the current state of the traffic lights that obtains from traffic lights Control Network 34 and the time Changing Pattern of traffic lights, calculate and choose the velocity range of suitable vehicle, be sent to suggestion speed display device 1 by traffic lights Control Network 3 and show by its junction ahead.Wherein, signal conditioning package 2 can be arranged in the main control system in the traffic lights Control Network 3, also can be arranged in the opertaing device outside the traffic lights Control Network 3, does not limit at this.
When traffic lights 4 current states at vehicle front crossing were green light, promptly current was to allow for the first time to pass through.From the current time when traffic lights 4 is shown as that no through traffic for the first time be T
1, then vehicle is V by the minimum speed of this green light normally for the first time
1,, advise that then first velocity range R1 that shows on the speed display device 1 is M～V this moment if the maximal rate of this road regulation is M
1, this normally advises first velocity range of demonstration on the speed display device 1.From current be T to allowing for the second time the time when current
2, corresponding therewith, avoid vehicle to stop at the crossing and normally by this second time green light maximal rate be V
2From the current time when for the second time no through traffic be T
3, corresponding therewith, smoothly by the second time green light minimum speed be V
3, advise that second the velocity range R2 that shows on the speed display device 1 is V this moment
2～V
3By that analogy, since second velocity range R2, n only is taken as the even number since 2, then from current be T to allowing the time when current for the n/2+1 time
n, then current vehicle is V by the maximal rate of the n/2+1 time green light
n, from the current time when no through traffic to the n/2+1 time be T
N+1, then current vehicle is V by the minimum speed of the n/2+1 time green light
N+1, n/2+1 the velocity range Rn that shows on the suggestion speed display device 1 is V
n～V
N+1
Wherein,
When the traffic lights 4 at vehicle front crossing is current when being red light, promptly current is that no through traffic for the first time, then allows current current for allowing for the second time next time.From current be T to allowing for the second time the time when current
2, corresponding therewith, avoid vehicle to stop at the crossing and normally by this second time green light maximal rate be V
2From the current time when for the second time no through traffic be T
3, corresponding therewith, smoothly by the second time green light minimum speed be V
3, advise that second the velocity range R2 that shows on the speed display device 1 is V this moment
2～V
3By that analogy, since second velocity range R2, n only is taken as the even number since 2, then from current be T to allowing the time when current for the n/2+1 time
n, current vehicle is V by the maximal rate of the n/2+1 time green light
n, from the current time when no through traffic to the n/2+1 time be T
N+1, current vehicle is V by the minimum speed of the n/2+1 time green light
N+1, n/2+1 the velocity range Rn that shows on the suggestion speed display device 1 is V
n～V
N+1
Wherein,
The preferential less velocity range of numbering n that shows in suggestion speed display device 1 speed of displaying scope Rn.
In the various embodiments described above, the utility model system also comprises a plurality of sensors that are used to gather intersection vehicle flux, such as being laid on underground coil and pressure transducer, camera commonly used and traffic state analysis software, infrared heat quantity sensor etc.These sensors all are arranged near highway section comparatively complicated traffic lights 4 crossings and crossing thereof, the traffic state information at the place, corresponding traffic lights 4 crossings that it will collect flows to signal conditioning package 2 by traffic lights Control Network 3, so that signal conditioning package 2 filters out the velocity range that more meets current road conditions from the velocity range that calculates.For example: first velocity range that above-mentioned signal conditioning package 2 calculates is 80～60km/h, second velocity range 40～20km/h, but present road and not smooth, the current wagon flow average velocity that records by sensor is 30km/h, vehicle reaches 60km/h and has difficulty so.And the current wagon flow average velocity 30km/h that sensor records is just within second velocity range 40～20km/h, so signal conditioning package 2 can send to suggestion speed display device 1 by traffic lights Control Network 3 with the velocity range of 30～20km/h and shows.
In the various embodiments described above, the renewal frequency of suggestion speed display device 1 displaying contents also can be arranged in the suggestion speed display device 1.
In the various embodiments described above, the vehicle that signal conditioning package 2 calculates is by the velocity range of junction ahead, also can independently network or cell phone network or radio station send to suggestion speed display device 1 by display device.
In the various embodiments described above, also can manually pre-set velocity range in the signal conditioning package 2 according to actual conditions.
In the various embodiments described above; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model,, should not get rid of outside protection domain of the present utility model improvement and the equivalents that individual component is carried out.
