A method for determining the trajectory of traffic flow at an intersection, which relates to the field of traffic conflict of mixed traffic flow in traffic engineering. The image coordinates of a traffic individual are obtained through the view software, and the actual coordinates of a traffic individual at any time can be obtained through the conversion formula of image coordinates and actual coordinates. There are 8 unknown matrix conversion coefficients in the conversion formula, and the matrix conversion coefficients can be obtained by marking 4 points with known image coordinates and actual coordinates at the intersection, and bringing the image coordinates and actual coordinates of the marked points into the conversion formula. On the basis of determining the 8 conversion coefficients, the actual coordinates of a certain traffic individual at all times to be obtained are obtained, and the coordinate system is drawn to be the driving trajectory of the traffic individual. The invention has important significance for the quantification of traffic conflicts at intersections, the prediction of black spots of traffic accidents and the improvement of traffic safety.

The invention discloses an airport demisting system and a demisting method. The system comprises a plurality of outdoor demisting electric heating blanket bodies, a steel chisel, a strapping tape andan electric heating power source system. The airport demisting system has the advantages that the local visibility near the outdoor large-area terrain can be improved under the mist condition, and larger benefits are achieved when the system is applied to busy or large airports. During use, only transporting, loading and unloading are needed, demounting and mounting are convenient, the system canbe stored to be used many times, special maintenance is not needed, and operation is easy and convenient. The power is adjustable, demisting is carried out by changing the local air temperature condition of the low altitude, and then the visibility of the local area of the low altitude is improved. Environmental pollution is avoided, and the system can be used for a short time according to the mist condition and needs. Safe flight can be guaranteed by improving the visibility, social benefits, economic benefits and the technology and management level can be improved, service quality can be improved, and the comprehensive traffic order and the social reputation of civil aviation are improved. Then the hourly rate of the airports, runways and airplanes are increased, the effects of increasing revenue and reducing expenditure are achieved, the flight delay rate caused by the mist can be reduced, and the annual flight on-time performance statistical level is greatly improved.

The invention provides an intelligent mobile traffic lamp comprising a pedestal, a lamppost and a control module, wherein four side faces of the lamppost are provided with traffic lamp holders, and four sides of the lamppost are respectively provided with vehicle detection devices; each time when a vehicle passing by the lamppost is detected, a counting signal is sent to the control module; lighting duration of each traffic lamp holder is controlled via the control module through the following steps: two vehicle detection devices arranged in a back-to-back manner are set as group A while the other two are set as group B, time intervals between two adjacent counting signals sent via the group A and the group B of the vehicle detection devices are random variables A and B, desired values E (A) and (B) of the random variables A and B are calculated, and a red light lighting duration ratio between a lane corresponding to the group A of the vehicle detection devices and a lane corresponding to the group B of the vehicle detection devices is E(A) / E(B). The intelligent mobile traffic lamp can be used for automatically adjusting traffic light waiting time according to traffic condition of a current crossroad, and therefore traffic order can be optimized to an optimal condition.

The invention relates to a traffic facility, that is, a safety guardrail for an urban level crossing. The safety guardrail is composed of a main machine part compartment column 8 and an auxiliary machine part compartment column 1 as well as a base 15 and a guardrail belt 7 thereof. The safety guardrail is characterized in that the main machine part compartment column 8 and the auxiliary machine part compartment column 1 are connected into a whole part by the guardrail belt 7 provided with a conductor and linked with a traffic light, the guardrail belt 7 correspondingly raises, falls and stopswith signal changes of the traffic light, thus realizing automatic no-passing and passing control of non-motor vehicles and pedestrians at the urban level crossing. The safety guardrail has the advantages of simple structure, easy assembly and disassembly, low maintenance cost, beautifulness, practicality and no safety hazard, can effectively reduce urban traffic accident rate, improve software level and hardware level of urban traffic facilities, facilitate to take away inelegant semaphore and tricing line phenomena of urban traffic wardens, and greatly improve traffic order of urban level crossings.

The invention relates to a method for real-time detection of human behavior of violating vehicles. The method comprises the following steps: 1) parsing video data into picture frame information; 2) detecting the zebra crossing area in the picture; 3) detecting the position of the vehicle in the picture; 4) Carry out speed detection and trajectory tracking of vehicles; 5) When a vehicle crosses the zebra crossing and the speed exceeds the threshold, pedestrian detection is performed on the positions at both ends of the zebra crossing; 6) If there are pedestrians waiting at both ends of the zebra crossing, the vehicle crossing the zebra crossing at high speed is Violating vehicles that do not comply with the regulations of the car owner; 7) Carry out license plate recognition on the violating vehicles. Compared with the prior art, the present invention has good detection performance, high capture rate of violations, low false alarm rate, and strong robustness. It can automatically detect zebra crossing areas of different shapes, and can identify the license plate numbers of illegal vehicles, thereby Promote the improvement of traffic order and reduce the occurrence of traffic accidents.
