This steering order is such as clearance time and/or stand-by period; When the left-hand rotation lamp at this crossing and craspedodrome lamp are arranged respectively, this steering order comprises the left-hand rotation clearance time and/or turns left the stand-by period, and the craspedodrome clearance time and/or keep straight on the stand-by period, and when this crossing is also provided with right-hand rotation lamp, this steering order also comprises the right-hand rotation clearance time and/or turns right the stand-by period.
According to the number of vehicles of this collection, produce the method detailed of the steering order of traffic lights, such as comprise: after energy-saving traffic signal lamp treatment facility 10 receives the number of vehicles that energy-saving traffic signal lamp 20 reports, the steering order to energy-saving traffic signal lamp 20 is produced according to this number of vehicles and crossing traffic flow upper and lower bound, thus the clearance time realizing distributing in the many directions of vehicle is long and/or the stand-by period is short, the clearance time of the direction distribution that vehicle is few is short and/or the stand-by period is long.
It should be noted that, this crossing traffic flow upper and lower bound also can carry out calculating by energy-saving traffic signal lamp treatment facility 10 voluntarily according to the number of vehicles reported and obtain.Such as, be 1 sampling unit once to gather duration, 5 sampling units are one and calculate sample, utilize statistical average stdev method, calculate vehicle in the generation unit interval and pass through the upper and lower bound of crossing quantity (i.e. crossing traffic flow).If energy-saving traffic signal lamp treatment facility 10 calculates crossing traffic flow upper and lower bound voluntarily, then energy-saving traffic signal lamp 20 does not need to add up this value and report.
Energy-saving traffic signal lamp treatment facility 10 calculates this number of vehicles, divided by collection duration, to obtain unit interval number of vehicles, it is consistent with crossing traffic flow unit, the unit of the such as magnitude of traffic flow is/minute, then the unit of unit interval number of vehicles is also/minute.
Energy-saving traffic signal lamp treatment facility 10 judges this unit interval number of vehicles and the relation between the crossing traffic flow upper limit and lower limit, decide clearance time and/or stand-by period, such as when this number of vehicles is more than or equal to the crossing traffic flow upper limit, setting clearance time span is T1 and stand-by period is T1 ', or only setting clearance time span is T1, or only the setting stand-by period is T1 '; When this number of vehicles is less than the crossing traffic flow upper limit and is more than or equal to crossing traffic flow lower limit, setting clearance time span is T2 and stand-by period is T2 ', or only setting clearance time span is T2, or only the setting stand-by period is T2 '; And when this number of vehicles is less than crossing traffic flow lower limit, setting clearance time span is T3 and stand-by period is T3 ', or only setting clearance time span is T3, or only the setting stand-by period is T3 '; Wherein T1 is more than or equal to T2, and T2 is more than or equal to T3, and T1 ' is less than or equal to T2 ', and T2 ' is less than or equal to T3 '.Utility model
In another embodiment, energy-saving traffic signal lamp treatment facility 10 timesharing can also decide clearance time and/or stand-by period.Such as, at traffic low peak period (as 9:00-11:00,15:00-17:00,21:00-7:00 next day) set by T1, T2, T3 be less than rush-hour (as 7:00-9:00,13:30-15:00, T1, T2, T3 18:00-21:00), and/or T1 ', T2 ' set by traffic low peak period, T3 ' are greater than T1 ', T2 ', T3 ' set by rush-hour.
Above-mentioned number of vehicles can for the up-to-date number of vehicles reported, also can for carry out the number of vehicles after statistical average to the number of vehicles reported in a period of time, and the utility model is not as limit.
In addition, when the left-hand rotation lamp at this crossing and craspedodrome lamp are arranged respectively, can preset different threshold values for left-hand rotation lamp respectively from craspedodrome lamp, also can arrange identical threshold value, the utility model is not as limit.
When this crossing is also provided with right-hand rotation lamp, the threshold value different from the lamp that turns left, craspedodrome lamp can also be preset for right-hand rotation lamp again, or identical threshold value, the utility model is not as limit.
Step S4: control this traffic lights by this steering order.
Such as, clearance time and/or the stand-by period of traffic lights is controlled.
The communication module 202 of energy-saving traffic signal lamp 20, or the communication module 302 of energy-saving traffic signal lamp control device 30 receives the steering order that energy-saving traffic signal lamp treatment facility 10 transmits, and this steering order is transferred to the control module 203 of connected energy-saving traffic signal lamp 20, or the control module 303 of energy-saving traffic signal lamp control device 30.
The control module 203 of energy-saving traffic signal lamp 20, or the control module 303 of energy-saving traffic signal lamp control device 30 receives this steering order, according to this steering order to control traffic lights.
Energy-saving traffic signal lamp control system of the present utility model, vehicle flowrate according to the crossing gathered carries out Energy Saving Control to traffic lights, achieve and measure object that is current, the distribution according to need vehicle pass-through time, thus efficiently solve path resource and to pass through wasting phenomenon, improve traffic efficiency, reduce the signal timings such as idling parking, economize energy, reaches energy-conservation object.
Below illustrative embodiments of the present utility model is illustrate and described particularly.Should be appreciated that, the utility model is not limited to disclosed embodiment, and on the contrary, the utility model intention contains the various amendment and equivalent replacement that comprise within the scope of the appended claims.
