Safety Cameras

USE OF SAFETY CAMERAS FOR TRAFFIC MANAGEMENT

A CCTV system is a closed video system where the signal is transmitted to a limited set of monitors, restricting the view to a certain set of people with specific purposes. Closed circuit television (CCTV) refers to the use of video cameras to transmit signals to a specific place with a set of monitors. Traffic control is becoming a critical application for CCTV. A typical CCTV system is composed of a camera system, reviewing displays and a central controller.

• CCTV provides a way to monitor multiple cameras internally and analyse generated images to extract useful information about traffic parameters, such as 
• speed
• traffic composition
• vehicle shapes
• vehicle types
• vehicle identification numbers and 
• occurrences of traffic violations or road accidents. 
• This offers a great help for transportation authorities, allowing them to make decisions accordingly and distribute traffic information to drivers, resulting in 
• improved traffic flow
• prompt accident detection
• shorter journey time
• less fuel consumption
• reduced emissions and 
• more satisfied travelers
• In the context of vehicles traffic management, there are two different perspectives to be considered
• the driver’s perspective and 
• the traffic authority’s perspective.
• `By studying reoccurring traffic patterns and trends, it is possible to learn how they are formed and why.
• Image-based CCTV systems have the ability to recognise unusual and abnormal events on roads by analysing digital images and extracting traffic parameters such as speed and traffic composition. Special software tools are usually used to help in recognising vehicle shapes, vehicle types, vehicle identification numbers and occurrence of traffic violations or road accidents.
• Automatic Number Plate Recognition (ANPR) system as an example of such tools
• After processing captured data and detecting an incident, two different approaches are available in the literature to implement the system reaction:
• Manual reaction and
• Automatic reaction
• CCTV leads to better traffic control.
• However, CCTV systems are extremely costly to install and operate and are offensive to privacy
• CCTV systems are increasingly used for road monitoring and traffic control systems. 
•  The computer analysis process of CCTV data is important to reduce errors and cost in terms of time and money.
