Road Traffic Analysis
Road Traffic Analysis (RTA) is the most important process in road traffic management. A properly built road traffic management system, which is based on the comprehensive analysis of road traffic, can increase the traffic capacity of existing motorways.
A road traffic analysis (RTA) system comprises a number of solutions that consist of the following systems:
Video Surveillance System
This system makes it possible to remotely watch the situation on motorways. The system consists of video surveillance cameras and specialized software designed to manage the cameras and the video data they record and to interface with the other systems within a road traffic management and analysis complex. It also includes a system for intellectual analysis of video data.
Visual Information Display and Recording Instruments
Such instruments are designed for keeping records of the video data provided by the video surveillance system and for subsequent processing of such video data.
Automotive Number Plate Recognition, Registration, and Database Management System
Number Plate Automatic Recognition is a surveillance system that uses the method of optical character recognition (OCR) from images to read out number plates of motor vehicles. Such system can utilize the standard video cameras intended for the video surveillance system. However, we recommend using specially designed cameras to ensure the maximum efficiency.
Central Dispatching Control Station
LED-based Road Signs and Data Screens with Variable Information
Jointly with the other systems within the complex, these components make it possible to optimize the movement of motor vehicles by means of informing the drivers about complicated road sections or about changes in the road traffic conditions within the motorways under control. This all makes it possible to decrease the probability of traffic jams.
A road traffic analysis system makes it possible to accomplish the tasks as follows:
- Remotely supervising the movement of motor vehicles at street and motorway crossings;
- Watching over such cases as complicated traffic in particular areas, road accidents, and violation of traffic rules;
- If required, an operator can, upon receiving an image from a troubled road section, remotely control the road traffic by means of changing the operating mode of traffic lights;
- Making fast decisions as to calling up the relevant authorities (traffic police or ambulance) in the event of a road accident or in any other problem situations;
- The present-day computer tools for image analysis make it possible to automatically collect the data about road traffic and to detect any traffic complications in particular areas, such as traffic jam, road accidents, and violations of traffic rules at troubled sections of motorways and at crossroads;
- The video surveillance system has a territorially distributed structure in order to ensure uniform control and management operations from the central dispatching station. Objects are equipped with a digital video surveillance system of a new generation based on IP technologies.
Such a structure of video surveillance system will ensure the access to all devices operating within the network. Besides, the system will make it possible to watch the video archives with the data removed from local recording devices and to identify the alarm activation parameters.
The main emphasis is made on the possibility to analyze the data provided by cameras in the automatic mode with timely notifications to the relevant authorities in the event of an alarming situation. This will make it possible to efficiently control large areas without the need to increase the number of video surveillance personnel. The video data analysis modules are located directly at the video cameras, and that makes it possible to easily increase the size of the video surveillance system without the need to install any additional servers for processing of video data. The system also makes it possible to set a logical sequence for image display from the video surveillance cameras at an operator's video screen, and to link the camera pictograms and the relevant video windows to location maps, and to set the parameters for alarm signal activation. There is also an opportunity to set the patrol routes. It is also possible to record all events to a network disk space and to provide access to the video archives from any point within the network in the course of a specified period of time.
The alarm signal activation parameters can be set based on the analysis of the following events:
- Control of the motor vehicles parked at restricted areas;
- Control over the motor vehicles that violated the traffic rules (making a turn at a restricted area; red lights running; wrong lane running; crossing a double solid line; restricted lane running; etc.);
- Motor vehicle speed control;
- Motor vehicles size control;
- The system operating in the automatic mode to enable the video surveillance operators to simply look thru the alarming events log in order to find the type, date, and time of an alarming event, instead of watching their video screens for 24 hours a day. The operators will thereafter just have a look at the video recording of the relevant event. Based on the data obtained, the operators make decision on taking appropriate measures.
Such a setup of work of video surveillance operators makes it possible to essentially decrease the number of the events passing unnoticed due to a decrease in the human fatigue factors.
