Description
The road traffic that technical field the present invention relates to use in a kind of urban traffic control block up detection alarm system and operation method thereof.
Background technology all is to use to spread over the online wagon detector in urban road as the traffic detection means in modern urban traffic management, detects the magnitude of traffic flow and the traffic congestion of road.
The traffic signal control system of widespread use at present both at home and abroad all has by vehicle the situation of occupying of wagon detector is calculated the function of current road traffic congestion degree, in view of the above and design generates the signal controlling preferred plan of following one-period or downstream road junction traffic flow.Along with expanding economy, motor vehicle quantity increases severely, and urban highway traffic has been in state of saturation, particularly in rush hour morning and evening.When traffic accident such as traffic hazard, vehicle trouble, traffic offence driving behavior takes place, if can not get handling timely, will cause road traffic and stop up and spread to periphery rapidly, when serious even can cause the local traffic paralysis.
Whistle control system can only calculate the road degree of crowding from the traffic overall trend in the prior art, for best state---the traffic congestion by the road traffic congestion that various accident caused, then can not find fast, Rapid Alarm.Normal traffic congestion can be predicted, and also can only alleviate as possible by some conventional traffic engineering means (as using advanced traffic signals control); Then different by traffic congestion that accident caused, since accident have multiple, spatial and temporal distributions is uncertain, and characteristics rapid to the current influence of normal traffic and that infringement property is big, therefore require traffic-police must accomplish rapid reaction, fast processing causes the various accidents that road traffic blocks up, thereby avoids forming large-area traffic paralysis.Realize this goal, most important, the most basic, also be the most difficult be exactly how to find fast the field point that road traffic blocks up takes place a bit, have only quick discovery, the ability fast processing.
Summary of the invention the objective of the invention is to overcome the deficiency of prior art, urban road traffic congestion detecting alarm system and operation method thereof on the wagon detector basis that a kind of existing whistle control system is provided and links with it, be intended to solve quick discovery because this difficult problem of traffic congestion that the different kinds of roads accident is caused is accomplished quick discovery, Rapid Alarm.Traffic congestion detecting alarm system provided by the invention is achieved in that
Urban road traffic congestion detecting alarm system, comprise and be arranged on the wagon detector on each detected highway section and be attached thereto the traffic signal control system that connects, can upload current wagon detector status data and current traffic lights clearance phase data, it is characterized in that:, the traffic abnormity that has an operation and have wagon detector database and traffic abnormity to analyze alert program analyzes alarm computer, this computing machine and the networking of above-mentioned traffic signal control system receive current wagon detector status data and current traffic lights clearance phase data.
The main field that traffic abnormity is analyzed the wagon detector database that moves on the alarm computer comprises: clearance stage, the alarming threshold value time of the numbering of the numbering of wagon detector, the title of corresponding road section, corresponding traffic light, correspondence.
Traffic signal control system is all per second once to the speed that traffic abnormity analysis alarm computer transmits current wagon detector status data and current traffic lights clearance phase data.
Every group of the current wagon detector status data of traffic signal control system transmission is made of wagon detector numbering, two character strings of this wagon detector current state, and every group of current clearance stage two character strings by traffic lights numbering, these traffic lights of current traffic lights clearance phase data constitute.
Traffic abnormity is analyzed the traffic abnormity analysis alert program of moving on the alarm computer and is had wagon detector status monitoring table, main field comprises the numbering of wagon detector, the title of corresponding road section, the numbering of corresponding traffic light, the corresponding clearance stage, the current clearance stage, current duration of occupancy, current totally free time, the alarming threshold value time, alarm detection time window timer, current alarm condition, this program is revised wagon detector status monitoring table immediately according to the current traffic lights clearance phase data packets of information and the current wagon detector status data packets of information that receive, related data is analyzed in the his-and-hers watches then, judge, for not being in alarm condition at present as yet, end the wagon detector that is taken continuously in this alarm detection time window and send jam alarming but be opened to the alarming threshold value time, for being in alarm condition at present from the clearance green light, but being opened to the alarming threshold value time from the clearance green light ends in this alarm detection time window the wagon detector that accumulative total free time has been not less than 3 seconds and cancels warning.
The ultimate principle of said system is: the parking queuing of supposing a certain flow direction of a certain signal lamp control crossroad queues to or surpasses wagon detector from stop line, so under the normal condition clearance green light open bright after, these queuing vehicles will start in turn and move ahead, also begin to start until the vehicle of on wagon detector, waiting for and move ahead, from the clearance green light open the bright vehicle of waiting for to wagon detector leave wagon detector required be called maximum queuing checkout time during this period of time.If a certain flow direction opens bright from the clearance green light, to through till maximum queuing checkout time and suitable redundancy time, detecting device is taken all the time continuously, and the queuing vehicle that promptly is parked on the wagon detector is not moving all the time, illustrates that this flow direction necessarily accident has taken place and caused traffic abnormity.According to this principle, at first set up a wagon detector database, wherein there are pairing clearance stage of each wagon detector and alarming threshold value time (the maximum queuing checkout time of this detecting device adds a suitable redundancy time); Traffic abnormity is analyzed alert program the situation that takies continuously of each wagon detector is monitored, light in this alarm detection time window that alarming threshold value time of setting ends if open from the clearance green light, certain wagon detector is taken all the time continuously, then sends the warning message of this wagon detector institute corresponding road section generation traffic abnormity immediately.
Usually, during the motor vehicles parking queuing, vehicle length add and front truck between spacing on average be about about 4 meters, the clearance green light open bright after, the checkout time of average every queuing vehicle is about 1.5 seconds, therefore, is example with wagon detector apart from 100 meters of stop lines, and fleet's length was about 25 chassis when the row of fleet was full, and required queuing checkout time is about 38 seconds, add for about 20% redundancy time, then the alarming threshold value time can be set at 45 seconds.Bright back wagon detector is still taken continuously and above 45 seconds, illustrate that then this highway section accident takes place causes traffic abnormity if the clearance green light of this direction opens, and should send warning message immediately.Therefore, the pairing alarming threshold value time of each wagon detector all should specifically be set by calculating or measuring according to factors such as wagon detector position, condition of road surface by traffic engineer.Generally, the alarming threshold value time should be greater than the traffic lights cycle.
