The inductive electromagnetic method that utilizes proposed such as " patent No. 201,110,439,431 1 kinds of road traffic flow collections and Forecasting Methodology " carries out the traffic throughput monitor system monitored. When vehicle is through installing the road surface of solenoid, electromagnetic detection signal changes, system counts, by adding up the change of electromagnetism signal, the quantity crossing vehicle, and obtains in specified period the parameters such as wagon flow amount, V-bar, occupation rate and traffic density, it is achieved the monitoring of traffic flow. But solenoid needs excavated pavement when mounted, installation process is very inconvenient. Also it has been proposed that adopt the speed of supersonic method or Doppler method monitor vehicle, but ultrasonic wave is subject to outside temperature, airflow influence, and Doppler method can not monitor object that is static or low-speed motion." patent No. 201320243123 combined type traffic flow monitoring " then proposes a kind of multiple detection system being carried out and integrates the method simultaneously monitored, to reduce external environment to the interference of monitoring result, but the monitoring equipment that composite algorithm uses is many, process data are huger, complicated integral structure, and cost is higher. In addition, above-mentioned monitoring method does not possess the function drawing numeral map, and by wireless network, gained information cannot be sent to officer.
At present, having system described in relevant patent to possess the function that gained traffic information is sent to officer, such as " patent No. 201210202111 car flow-monitoring device ", this invention is provided with terminal module on car, in the gangway on road, master control module, each other receiving and transmitting signal are installed.

But this system cost is higher, the gangway of automobile and each road all needs to install master control module to realize and the message exchange of terminal module.
Comparatively speaking, the with low cost and more comprehensive system of function has " the traffic flow real-time monitoring systems of the patent No. 201,210,551,324 1 kinds of unconscious participations ". This invention is a kind of traffic flow monitoring technology based on Android operation system, wireless communication technology and network technology. Its principle of work is: acceleration and the GPS coordinate information 1) being arranged on the smart mobile phone end software active acquisition mobile phone possessing acceleration transducer function, and is uploaded onto the server; 2) institute's value is analyzed by server, utilizes acceleration change and GPS coordinate information to calculate somewhere and traffic jam occurs, and information is sent to smart mobile phone; 3) in the map information at smart mobile phone end interface, traffic information is shown in a graphical form. The weak point that this system exists is: the first, and this system is mainly based on Android operation system, and the mobile phone terminal of other operating systems cannot use, and server also cannot obtain the information of these mobile phone place vehicles; 2nd, this system using the acceleration change of equipment as judge road conditions according to (when automobile runs into traffic jam can start and stop frequently, acceleration, acceleration), but the pedestrian on road also can carry the equipment that this system is housed, their acceleration and positional information also can be collected and be difficult to distinguish with vehicle by serviced device, thus cause data to cause confusion; 3rd, this system does not possess the function of traffic accident monitoring.

Embodiment
Mobile communication device must have GPS or the location such as the Big Dipper or Galileo function. Native system runs the software installed on the communication device, obtains position and the speed information of vehicle in real time.
After running software, communicator receives the current traffic information from server automatically, and starts to collect the position and speed information of this communicator position. After information gathering is complete, first the positional information of equipment is processed by software, and whether judgment device is on urban district or motorway. If equipment is on a highway, gained information is uploaded onto the server by software again by wireless network.
After the speed that server collects equipment and positional information, start road conditions to be analyzed. The computation model analyzed is according to being: when road conditions are different, the distribution situation of running velocity is also different. Native system obtains the speed of all devices on certain section of highway, and becomes velocity profile according to these numeric renderings, judges the jam situation in this section with this. Being specially, the travelling speed of unobstructed its vehicle of road is fast, and velocity distribution does not steadily have larger fluctuation as shown in Figure 1. The road being in peak period on and off duty, road side is in unobstructed state, and another side of road slightly blocks up, and running velocity is relatively slow, but velocity distribution is relatively steadily as shown in Figure 2. During traffic congestion, the traveling speed of vehicle is very slow, and its distribution is as shown in Figure 3. Crossroad place (when sending out a warning), usually as shown in Figure 4, road side speed trends towards 0 to its velocity distribution gradually, and another side car speed is fast, and vehicle is more discrete. Once there is traffic accident, accident vehicle speed is 0, and the speed of surrounding vehicles is central distribution, and namely the closer to the scene of the accident, the speed of vehicle is more as shown in Figure 5 slow.
