Embodiment tetra-:

The technical scheme of embodiment tri-: in (as a second) often at regular intervals, the intelligent traffic lamp system 1 at each crossing can send to system server by the status information of self traffic lights; In (as a second) often at regular intervals, system server all can send to the status information of the traffic lights of each junction node each car that adds this junction node; This pattern takies a lot of system resource, has also increased the communication cost of user (driver or traffic administration person).

In fact, in embodiment tri-, the message exchange direction of technical scheme is as shown in figure 15: the message exchange between intelligent traffic lamp system 1 and system server is unidirectional; Message exchange between system server and intelligent vehicle mounted terminal system 2 is two-way.The present embodiment is the improvement to embodiment tri-, and the message exchange direction in the technical program as shown in figure 16.

Intelligent transportation system (ITS) or the single intersection traffic signaling equipment of prior art, traffic lights program (or traffic lights subroutine) all operates in the traffic signaling equipment that is installed on crossing, and the program flow diagram of traffic lights subroutine is realized and belonged to known technology with concrete software.In the present embodiment, the traffic lights control program at all crossings in a city operates in system server, synchronouslyin intelligent traffic lamp system 1 and intelligent vehicle mounted terminal system 2, moving separatelywith traffic lights control program identical in system server, that is: " time set information (comprising cycle, split, phase differential etc.) and the current status information " of the traffic lights at the crossing of any one in system server by synchronized transmission to the intelligent vehicle mounted terminal system 2 that is arranged in the intelligent traffic lamp system 1 at any one crossing and application and adds any car of this junction node.The present embodiment is described to here and can finds out: from the angle of system server, intelligent traffic lamp system 1 is the same with the function of intelligent vehicle mounted terminal system 2, only intelligent traffic lamp system 1 is being controlled the lights state at crossing, place, and intelligent vehicle mounted terminal system 2 or at the lights state of the demonstration screen display junction ahead of smart mobile phone, at the lights state of the demonstration screen display junction ahead of instrument panel, or at " traffic lights in car " the provided by the invention upper lights state that shows junction ahead.

For example: as shown in Figure 2, a car just sails through forward A2 crossing, A1 crossing, and intelligent vehicle mounted terminal system 2 sends request the information that adds A2 junction node to system server by vehicle intelligent mobile phone; System server has sent the status information of the traffic lights at A2 crossing, through decoding: the traffic lights time of this car working direction is set and is: red light 30 seconds, green light 27 seconds, amber light 3 seconds, what show now is green light, has been shown to 18 seconds.Intelligent vehicle mounted terminal system 2 is called traffic lights subroutine, (as 1 second) often at regular intervals, the time now showing is deducted to 1 second, until reduce to zero, then show amber light, after 3 seconds, reduce to 0, show red light, (as 1 second) often at regular intervals, deducts 1 second by the time now showing again, until reduce to zero, so go round and begin again." often at regular intervals " that the present embodiment is set is 1 second, also free setting according to actual needs.In the process of traffic lights subprogram activation, arrive whole second moment (as 17 seconds, 16 seconds etc.), primary control program meeting call subroutine 4, subroutine 4 is display subroutine, the traffic signal light condition of this car working direction is presented on display screen, and by voice broadcast, as: red light 50 seconds, red light 40 seconds, Voice broadcast is determined and can be set by driver by the distance of motor vehicle and junction ahead the zero hour.

Obviously, the intelligent traffic lamp system 1 that is arranged in A2 crossing is moving same program, and is controlling the traffic lights that are installed on crossing and showing same state.For A2 crossing, as long as system server is not sent up-to-date " time set information and current status information ", the intelligent traffic lamp system 1 at A2 crossing by the ground of following the prescribed order, go round and begin again moving last control parameter, parameter comprises the real-time status information in time set information and a certain moment.

For guaranteeing stability and security, system server is sent after " time set information and current status information ", intelligent traffic lamp system 1 needs to carry out safety verification before execution, the one, in message with send time information, by the time system contrast with self, (three systems in Figure 16, by reaching time synchronized time calibration.), difference should be less than setting value ε (ε is according to actual set), the 2nd, there are several predefined signal lamp control models at each crossing, the time set information that system server is sent should be one wherein, and these two kinds of safety verifications can ensure the security of the intelligent traffic lamp system 1 at described crossing.

The technical scheme of the present embodiment, the solution of flexibility is provided for optimizing the control signal of traffic lights at each crossing, the present embodiment is realizing in the process of 18 functions enumerating in " tool of the present invention has the following advantages " in this instructions, take full advantage of the arithmetic capability of intelligent traffic lamp system 1 and intelligent vehicle mounted terminal system 2, save the calculation resources of system server, increase stability and the security of system simultaneously, and can minimize driver's communication fee.

Embodiment five:

Embodiment mono-to four explanation be " a kind of system and method for simultaneous display junction ahead traffic signal light condition ", what embodiment mono-and embodiment bis-adopted is two systems: intelligent traffic lamp system 1, intelligent vehicle mounted terminal system 2; Three systems and embodiment tri-and embodiment tetra-adopt: intelligent traffic lamp system 1, intelligent vehicle mounted terminal system 2 and system server.In fact, the architecture of embodiment tri-and embodiment tetra-is a kind of intelligent transportation system (ITS), by different design of hardware and software, can realize a lot of functions.

The present embodiment is on the basis of said system, realizes position of bus inquiry.

The travel route of city bus is fixed, there are some principles in bus company while determining travel route, one of them is exactly civic trip requirements, be not only so simple to terminal from initial point carrying meeting aspect the trip requirements of civic, they also require the travel speed of bus faster, the density of dispatching a car is larger, but, because urban transportation is more and more blocked up now, generally bus does not have accommodation road, bus arrives at a station on schedule and is difficult to realize, can realize that the starting station and terminus dispatch a car has on time been very high job requirement.

On the bus of some circuits in some cities, GPS or triones navigation system are installed at present, can in real time the positional information of bus have been sent to server end, for citizen's inquiry, where can determine the own nearest bus of distance.System provided by the invention also can realize position of bus inquiry.The system providing taking embodiment tri-and embodiment tetra-is basis, as shown in figure 17, when circuit according to the rules of Dang152 road bus (calling 152 cars in the following text) and official hour travel, always through the crossing on circuit, every intelligent vehicle mounted terminal system 2 of carrying through crossing 152 cars all can send request to system server, the status information of the traffic lights of the junction ahead of beaming back with acquisition system server, the information that 152 car utilizations need can realize " traffic lights in car ", when passing through behind this crossing, 152 cars can send request to system server again, request stops sending the status information of just passing through the traffic lights at crossing.In this process, 152 cars just leave a record in system server: when passed through which crossing and to which direction sailed, each crossing is a node on vehicle line.If passerby's first is prepared to take 152 cars in Shanghai way station, he uses the dedicated search software APP in mobile phone, input " 152 car ", show after the 152 all websites in tunnel, select " Shanghai way station ", the nearest car of rear chosen distance our station, clicks and confirms that rear system server can return message.In information, show: have 152 cars just through Beijing Road, travel direction is terminal; Have 152 cars just to pass through Shen Zhenlu, travel direction is initial point.System server also can provide the milimeter number apart from our station, or calculates the time that arrives our station by large data mining.In fact, if passerby's first is often taken 152 bus, he can be according to 152 bus station boards and the information of returning, and can judge the 152 bus about position now that oneself will take, also can judge the whenabouts that this car arrives at a station.Dedicated search software APP also can retrieve other information relevant with bus routes, as dispatch a car, the off-running time, the information such as the moment of a certain station bus arrival on circuit.

The present embodiment, in order to save the resource of system server, does not process the positional information beyond the crossing on bus routes.

Obviously, any motor vehicle starts to be all stored in system server through the information at crossing to " lower road network " cut-off institute from " road network ", for these information of protection privacy are for large data analysis, and can external disclosure.

Embodiment six:

A kind of intelligent transportation system (ITS) that is actually provided by the invention, by different design of hardware and software, can realize a lot of functions.

The present embodiment is on the basis of said system, accurately obtains pedestrian's trip requirements, and meets this demand by setting up " motor-driven public transport fleet ".

A lot of bar bus routes have been opened in each city, have all distributed a lot of buses on every circuit.The travel route of city bus is fixed, and there are some principles in bus company while determining travel route, and one of them is exactly civic trip requirements.But limited by technical conditions, the urban traffic control system of prior art cannot accurately obtain pedestrian's trip requirements in real time, also just can not meet quantitatively pedestrian's trip requirements.In fact, pedestrian's stream is that dynamic random changes, and prior art cannot be held.

The present embodiment need to be developed special mobile phone application, i.e. dedicated search software APP.The preparation person of taking bus goes to behind a certain station, opens this mobile phone application, input initial point station, and terminus, also needs input to prepare to take which road bus, after confirming, waits for.System server of the present invention moves certain subroutine, accurately count in real time number and the position distribution of preparing to take certain road bus (as 152 bus), if system server calculates existing bus and cannot satisfy the demands, just can meet this demand by bus management system allotment " motor-driven public transport fleet ".The LED screen that is arranged on the bus front portion of " motor-driven public transport fleet " will show 152 tunnels, and usually, system server also can be crossed note by the information exchange that increases bus and issue the pedestrian who prepares to take 152 bus.After task completes, the bus of increase will turn back to assigned address and await orders.This explanation " motor-driven public transport fleet " is to be distributed in each place in city while awaiting orders at ordinary times.

System server can command " motor-driven public transport fleet " to tackle some special circumstances sometimes.As shown in figure 18, be an area map in certain city, as mentioned above, go to behind a certain station when preparing the person of taking bus, open this mobile phone application, input initial point station, terminus, and input and prepare to take which road bus, after confirming.System server can move certain subroutine and draw traveler demand figure, in figure, with various symbol tables, " traveler initial point mark " and " traveler terminal mark " is shown.By this figure, the supvr of urban transportation can plan the bus routes making new advances, and commander " motor-driven public transport fleet " completes this task, simultaneity factor server is by the people of this mobile phone application of all uses of SMS notification, inform the information such as circuit, website and the frequency of new planning, make traveler ready in advance.Accurately, economical, be the Core Feature of intelligent transportation system provided by the invention (ITS) in real time.

Embodiment seven:

A kind of intelligent transportation system (ITS) that is actually provided by the invention, by different design of hardware and software, can realize a lot of functions.The present embodiment is controlled the green time of traffic lights according to the actual vehicle sum of each direction at each crossing.

Intelligent transportation system (ITS) or the single intersection controlling system of traffic light of prior art, the traffic lights control signal providing is fixed, or provide several control programs, select according to timing, for example: be a kind of scheme daytime, for all longer (can ensure " pedestrian's minimum is passed through the time ") of green time of the both direction of crossroad, allow more car fast by this crossing; Be another kind of scheme evening, for all shorter (can ensure " pedestrian's minimum is passed through the time ") of both direction green time of crossroad, to adapt to the less situation of people's car at night., although can measure in real time the vehicle flowrate at any crossing, measurement result is inaccurate for SCATS (intelligent traffic control system of Australia).

Intelligent transportation system provided by the invention can accurately add up in real time any one crossing not yet by the vehicle fleet at this crossing.Intelligent traffic lamp system 1 in embodiment mono-, embodiment bis-can be added up the vehicle fleet that not yet passes through this crossing (this is pattern one) at crossing, place; System server in embodiment tri-, embodiment tetra-can be added up the vehicle fleet that not yet passes through this crossing (this is pattern two) at any one crossing.The principle of statistics is: taking pattern one as example, as Fig. 2, shown in Figure 19, after the coding that the intelligent vehicle mounted terminal system 2 that a motor vehicle carries obtains junction ahead is A1, can forwards send request the information that adds this junction node in crossing according to the message format of setting, intelligent traffic lamp system 1 is for adding this junction node and not yet applying for that the vehicle fleet removing from this junction node can add up, and can add up very accurately, as shown in figure 19, it is M that the intelligent traffic lamp system 1 at A1 crossing can accurately be added up the vehicle fleet travelling to direct north, N to the vehicle fleet of due south direction running, Q to the vehicle fleet of just western direction running, P to the vehicle fleet of due east direction running.According to certain algorithm, move some subroutines, green time (needing to ensure " pedestrian's minimum is passed through the time ") that just can reasonable arrangement all directions, maximizes traffic efficiency.The Statistics of pattern two is identical with pattern one.

Embodiment eight:

The method that embodiment seven provides can improve the traffic efficiency at crossing to a certain extent greatly, but must ensure " pedestrian's minimum is passed through the time ".But in some cases as shown in figure 20, in the time waiting red light, North and South direction has car and east-west direction does not have car; Or also have a limiting case, a crossroad only has a car sometime; There is no pedestrian if at this moment this crossroad can detect, so the signal lamp of garage's direction is changed into green light and can improve yet the traffic efficiency of road network.

A kind of intelligent traffic lamp system that the present embodiment provides, comprise the traffic signaling equipment of prior art, traffic lights group with described traffic signals mechatronics, it is characterized in that, also comprise sensor, described sensor at least comprises one of the following kind: photoelectric sensor, piezoelectric sensor, infrared sensor, gravity sensor, gravity sensing sensor, Mageneto-sensitive type sensor, laser range finder, camera, radar, ultrasonic sensor, three-dimensional camera, infrared pick-up head, described sensor is electrically connected with described traffic signals mechatronics or with special processor.

As shown in Figure 3, pedestrian detection region only includes zebra stripes part, the region 31 of dotted line in Fig. 3; The scope that pedestrian detection region comprises in Fig. 5 is enough large, is the region 51 of dotted line.The present embodiment adopts photoelectric sensor to be arranged in four positions at 52 places in Fig. 5, in the time not having pedestrian to enter region 51, the described intelligent traffic lamp system at this crossing can be defined as this crossing " temporarily without pedestrian crossing ", and information is sent to system server (having for transmitting crossing state in information/message format).System server is according to the vehicle fleet of these crossing all directions, according to certain algorithm, move some subroutines, make the vehicle of all directions fast by this crossing by controlling the state of traffic lights, reduce the stand-by period, improved the traffic efficiency at crossing.Enter the surveyed area at this crossing if be carved with pedestrian when a certain, described intelligent traffic lamp system can revert to this crossing conventional crossing state, " there is pedestrian crossing ", and this crossing state is sent to system server, the control mode of the traffic lights of system server to this crossing will ensure " pedestrian's minimum is passed through the time ".

For ensureing safety, a technical scheme is to make pedestrian detection region enough large, makes system server have the enough reaction time, has both ensured pedestrian's safety, can shorten by controlling the state of traffic lights again the stand-by period of vehicle, improve the traffic efficiency of road network; Another technical scheme is that multiple sensors shares, and expands pedestrian detection region, and sensor is a lot of in the installation site at crossing, as walker signal lamp lamppost, traffic lights lamppost, high-definition camera erection column etc., also can determine separately suitable installation site.For example: two high-definition cameras for pedestrian detection function are installed in the position suitable at existing crossing, can be referred to as multifunctional stereo camera (SMPC), be called for short three-dimensional camera, can obtain object and pedestrian in three-dimensional Heng road, and calculate its course.Can understand the three-dimensional situation in X50 rice region, 50 meters, a crossing by two cameras, and understand on the whole 500 meters, three-dimensional camera front with interior environment.It should be noted that in crossing placement sensor to be not only to detect pedestrian, also detect other moving targets, as people by bike, people by motorcycle, other vehicles etc.Consider cost, can only be at some key crossing installation and measuring pedestrians' sensor, and only in regular hour section, use according to large data analysis.

Embodiment nine:

The technical scheme that embodiment seven provides is the in the situation that of ensureing " pedestrian's minimum is passed through the time " at crossing, according to the vehicle fleet size of system server actual count and direction, shorten the stand-by period of vehicle by controlling the state of traffic lights, improve the traffic efficiency of road network, this mode is to realize under " having pedestrian crossing " situation at crossing state; The technical scheme that embodiment eight provides realizes under " temporarily without pedestrian crossing " situation at crossing state, because without ensureing " pedestrian's minimum is passed through the time ", so the vehicle pass-through efficiency at crossing is higher.

There are several turnpike roads in each medium above city (city that urban population is greater than 1,000,000) of China, turnpike road cross form crossing be called large crossing, be characterized in that road surface is broad, track is many, and vehicle flowrate is large, is the transport hub in city, because going to the other end from one end, pedestrian needs for a long time, so the traffic lights cycle is long, vehicle need to wait for that more than two red signal could pass through, so driver is produced to certain psychological pressure by large crossing.

In order to ensure the unimpeded of large crossing, the vehicle supervision department in city has put into practice a lot of methods, generally speaking human and vehicle shunting according to the principle of traffic, because the speed of the speed of People's Bank of China and garage is not mated, the result of mixed flow is that vehicle " crossing passage rate " reduces, and this is also the root that causes large crossing congestion.Also, because large crossing is the transport hub in city, the period particularly has pedestrian to pass through crossing sooner or later peak period by day, so mixed flow is inevitable, blocks up inevitable.A kind of method that existing human and vehicle shunting adopts is to build subterranean tunnel, and a difficult point of this method is cannot construct because there being underground installation; Another kind method is to build overpass, and a difficult point of this method is that investment is huge, and overline bridge also affects the view in city after fixing.And above-mentioned two kinds of methods have a common deficiency: the pedestrian who has refuses to use, and still walks the walkway on ground.

The method that the present embodiment provides is at large crossing place, " crossing pedestrian's transfer car(buggy) " is provided, allow and prepare to sit on " crossing pedestrian's transfer car(buggy) " by the pedestrian at this crossing, this method has become large crossing at " without pedestrian crossing ", system server is according to the traffic lights at the large crossing of traffic light signal periodic Control through testing, if intelligent traffic lamp system provided by the invention has been installed at large crossing, and driver has used intelligent vehicle mounted terminal system, become so former seconds of green light when the traffic lights of garage's direction, vehicle Deng red light all can be ready under the prompting of intelligent vehicle mounted terminal system, when green light signals occurs moment etc. red light vehicle just as road train fast by this large crossing.As shown in figure 21, be a large crossing, both direction is all Four-Lane Road, this crossing be numbered H1, set up as shown in figure 21 8 pedestrian's transfer stations at this crossing, be numbered a～h.The traffic route of two " crossing pedestrian's transfer car(buggy)s " 211 setting in figure is annular, travel route is: a → b → c → d → e → f → g → h → a, for reducing pedestrian's stand-by period, two transfer car(buggy)s that arrange are equidistantly dispatched a car, counterclockwise travel along route 212, what in Figure 21, route 212 was drawn is single line, in fact should be two-wire, transfer car(buggy) 211 travels between two-wire, should be parked in outside two-wire on the vehicle of red light, because the vehicle outside two-wire is all waiting red light when transfer car(buggy) 211 jaywalk.Another travel route of transfer car(buggy) 211 is rectangle, as the travel route of a transfer car(buggy) 211 is: a → d → e → h → a; And another transfer car(buggy) 211 travel routes are: b → c → f → g → b.In the process of moving at transfer car(buggy) 211, pedestrian's pilot lamp at this large crossing is shown as the red light of forbidding that pedestrian passes through.The quantity of transfer car(buggy) 211 should be determined according to actual conditions.The operation of transfer car(buggy) 211 should be definite according to actual conditions, and as used transfer car(buggy) peak period morning and evening, off-peak period can not used.Driving transfer car(buggy) is the work of a high physical strength, if the place that conditions permit can set up driver to have a rest nearby, as the driver rest area 213 of setting up in Figure 21.From the angle reducing discharging, transfer car(buggy) can use electric motor car, if use electric motor car, can arrange many at this large crossing, for example arrange 4, wherein two in the time of operation, in addition two in charging, at this moment, together with Vehicular charging district being arranged into driver rest area, arrange that many cars are also to back up.For attract pedestrian take and ensure safety, " crossing pedestrian's transfer car(buggy) " can design exotic shape some, color is more gorgeous, and facilitates passenger getting on/off.From technical development angle, in the time of pilotless automobile technology maturation, " crossing pedestrian's transfer car(buggy) " can adopt pilotless automobile.

Because used " crossing pedestrian's transfer car(buggy) " at large crossing, realize human and vehicle shunting, if also used the system and method for simultaneous display junction ahead traffic signal light condition provided by the invention simultaneously, the traffic efficiency at large crossing at least doubles, and has reduced the stand-by period of vehicle and has realized energy-saving and emission-reduction.

Embodiment 12:

Adopt system and method for the present invention, can realize 18 functions that the present invention describes in " tool of the present invention has the following advantages ".Some functions wherein have been discussed in certain embodiments, and the present embodiment is introduced other three kinds.

The fusion of so-called crossing is to instigate the time set information of the intelligent traffic lamp system at two adjacent crossings of close together identical, and makes the identical signal of traffic lights group simultaneous display of the equidirectional on same path.For example: in the time that two adjacent crossing distances are less than 30 meters, can be set as " crossing fusion ", accomplish that signal lamp is simultaneously bright goes out simultaneously, these two crossings in a direction just as a crossing, can greatly improve " crossing passage rate ", avoid in the time that a crossing is green light another crossing or red light that direction is identical, signal lamp is asynchronous, will greatly reduce the traffic efficiency at these two crossings.When the crossing of first bus passage rate is 30,000 ms/h, the times that need by 30 meters of distances are: 30 meters of ÷ 30000 ms/h=3.6 seconds, in the time adopting system and method for the present invention, 3 seconds of having wasted when the prompting function of traffic light system has been avoided green light in car, be enough to compensation and cross the 30-50 rice needed time of distance, so " two adjacent crossings of close together " can be used " crossing fusion ", and intelligent transportation system provided by the invention (ITS) can accurately be controlled and realizes this function.

What " green light relay " realized is such function: each road all can cross and form crossing with several roads, each crossing place can set up traffic lights, when a car along this road when speed is at the uniform velocity travelled faster, just become green light whenever approaching Shi Gai crossing, next crossing, such function is just named " green light relay "." green light relay " technology makes vehicle at the uniform velocity travel fast at continuous several crossings, and vehicle need not stop, and has improved the passage rate at crossing, has improved the traffic efficiency of road network.But the shortcoming of " green light relay " technology is: same path contrary direction traffic efficiency in the time that a direction traffic efficiency improves reduces.So the reasonable application of " green light relay " technology is by the vehicle flowrate of intelligent transportation system provided by the invention (ITS) accurate measure road, in the time that the vehicle flowrate of a road has periodic regularity, can adopt this technology.For example: the morning peak period, on a certain road, drive towards the vehicle of downtown area by suburb many, carry out " green light relay " by suburb to downtown area direction; The evening peak period, the vehicle that this road drives towards suburb by downtown area is many, carries out " green light relay " by downtown area to suburb direction.Realize the quantity at the crossing of " green light relay " should appropriateness should be not too much.

In order to guide faster wagon flow to reduce " road network holding time ", in peak period morning and evening, a road is become to one-way road, as a road is become the one-way road of being driven towards downtown area by suburb by the morning peak period, the evening peak period, this road is become to the one-way road of being driven towards suburb by downtown area.Even if one-way road is interim setting, as long as changed the relative set in server, just can not exert an influence to driver.Adopt intelligent transportation system provided by the invention (ITS) can realize easily above-mentioned functions.
