Traffic intellectual monitoring system
The intellectual system of traffic monitoring is based on the video surveillance system and allows detecting automobiles and transport means without interference on the road. The system consists of the three main sub-systems (modules):
video monitoring of the traffic intensity;
identification of the state identity plates of transport means;
GPS-monitoring and transport control.
Sub-system of video monitoring of the traffic intensity
The users apply the entire system fragments; they have different tactics of reaction and sub-system control;
Control on Geodetic Information Systems (GIS), traffic lights, video cameras, near road objects, electronic display is carried out independently;
The low control effectiveness is a result of an absence of a single access to resources interface, consistent methods of the information display and the system integration.
Video monitoring and video detection of the transport means at the cross-roads as well as on the highways.
The module feasibilities:
1. Monitoring of the specified road parts.
2. The possibility to receive and process video images from different sources of video surveillance.
3. Calculation of automobiles amount for the certain period of time on the lane (with a period from 20 s), or for the day and night.
4. Determination of a traffic average speed for the certain period of time on the lane.
5. The lane average occupancy for the certain period of time on the lane.
6. The lane average emptiness for the certain period of time on the lane.
7. Transport means classification.
8. Signaling about the incidents and the transport means jam.
9. Signaling about poor visibility.
10. Use of extra modules for the system possibilities expansion and for the distance data and images receive.
11. The possibility of the fixation of transport means that break the road regulations.
1. The system elements are not needed to be mounted in the road surface.
2. The system can be used under different weather conditions.
3. Simplicity in the system installation, checkout, and use.
4. Signals flow for the traffic control system and on the executive unit.
5. The signals receiving from the traffic control system.
6. The data supply on the computer (the data base server).
7. The different operation modes for the cross roads and for the highway parts.
8. High reliability and simplicity in operation.
The system functions
- The display of an image received from different sources of the video signal on the monitor screen.
- Storage of the traffic stream monitoring specifications in the data base.
- Statistical analysis of the traffic stream parameters.
- Visualization of the traffic stream statistical characteristics.
The system feasibility display of traffic state on the roads
The interface to the traffic lights control systems is mounted
- optional control systems could be connected;
- the interface to the standard European systems is mounted in.
The image traffic control sensors:
- the systems video detectors.
The traffic state surveillance:
- the traffic jam information;
- the image from video cameras;
- the display state information;
- the traffic accidents information.
The traffic control software:
- receipt/transfer of the synchronized in time information.
Automobile identity plates detection system
The developed digital video surveillance system allows detecting the state identity plates of the transport means and building up a plate data base. The system can be used for the open sites security (for example, cars parking lots) or certain street parts controlled with the traffic monitoring system. There is a possibility to revise the plates archive, and also to adjust an alarm signal that activates on transport with a dangerous plate.
The module feasibilities:
- detection and identification of the state identity plates of transport means on the image which is received from the selected channels;
- creation of the state identity plates data base and work with it.
The system interface
The interface enables to improve the user interaction with the software.
The control and adjustment devices are compacted based on a principle of the similar functions unification; the navigation is carried out with a help of obvious and easy to understand means.
The automobile identity plates identification system functions:
- the received image display on the screen;
- the identity plates search on the transport means image, their detection and identification with the further input into the common plates data base;
- comparison of the identified plate with those plates from the data base (for example, for the transport means search);
- storage of the transport means color image with an identified plate on a computer hard disk;
- the scanning of the identified plates data base and their saved images;
- creation of a special extra archive list which is filled in by a user. Its element is a state identity plate, the appearance of which in the controlled zone gives rise to an alarm signal (automobiles in a search, VIP automobiles, etc.).
Video surveillance:
- the system parameters flexible adjustment allows to change:
current adjustment of received images;
current adjustment of the archive saving;
- the detection system sensitivity to an automobile center;
- the system sensitivity to a zone search (the plate detection zone);
- the image scanning in a multi screen mode (four cameras) or a mono screen mode (one camera);
- the convenient inputting of the fixed with the system events in the form of the list which contains all the elements of detected plates data base list with indication of a detected plate, a channel (on this channel image of this plate was fixed), detection date and time.
Archive
The archive (the plates data base) allows scanning the system operation results, i.e. the plates detection results.
To make the work convenient the archive consists of several sections where the accumulated information is compacted.
These sections are:
- the detected plates data base;
- the plates in search data base.
Based on the archive data (in particular and with a help of filter) the following is possible:
- the required plate search (including search on a region plate);
- the search by time;
- classification of the archive data by a plate, camera, time or date.
GPS-monitoring and ground moving objects control
The technology of integration of satellite navigation system, wireless communication, GIS system, and the Internet-technologies has been developed based on advanced microelectronics and software. This technology will allow increasing qualitatively the moving objects safety and effectiveness of the resources control in the auto transport industry, and also will provide advanced opportunities for unmanned objects control at a distance.
The system allows the following:
- to monitor any amount of moving objects;
- to obtain the information about the objects location site with an accurate localization on the map of the movement direction and speed;
- to receive the objects movement statistics for any specified time period with all movements mapping;
- to receive the information about the objects distance covered in kilometers;
- to specify an individual surveillance mode (on a location site frequency and interval fixation) for each object; together with that a user or a users group can control the certain transportation means movements with individually agreed access rights;
- to keep a permanent connection with all transport park objects irrespectively of the time and their location area;
- to inquire about a single object location site, the whole transport park, and also objects located in a certain zone;
- to store the information about each object in the data base, including itineraries, announcements exchange;
- to specify intervals for messages receiving about the transport means movement and technical state: speed, coordinates, fuel quantity in tanks, mass (if sensors are available);
- to specify the area on the map, when the message about the exit from this area is sent to a traffic controller.
A mobile device AVL/GPS provides the following characteristics:
- 16-channel GPS-receiver provides determination of current coordinates in the WGS-84 format;
- the data (coordinates) transfer in the GPRS, SMS formats;
- voice communication (the GSM mode);
- urgent call;
- urgent coordinates transfer emergency;
- the information detectors entry/exit channels.
The system can be also successfully used for an effective control and work coordination of the automobile evacuators.
