Dahua smart solution helps spot traffic violations

Hangzhou, China

According to the recent World Health Organization data, approximately 1.3 million people die as a result of road accidents each year, costing most countries approximately 3% of their Gross Domestic Product (GDP). Nearly 93% of the world's fatalities on the roads occur in low- and middle-income countries, even though these countries have around 60% of the world's vehicles.

WHO suggests that one effective intervention to address traffic issues is to design safer infrastructures and incorporate road safety features into land-use and transport planning. Thus, implementing intelligent solutions like the Dahua Traffic Management Solution is of paramount importance to help ensure road safety at all times.

The traffic enforcement feature of Dahua's Traffic Management solution is able to offer an array of intelligent detection systems designed to accurately capture various kinds of traffic violations on the road. Some of the traffic violations that this solution can detect are described below.

Intersections and crossroads

This solution provides detection for pedestrian crossing, illegal lane changing, disobeying road direction signs, and parking in bike lanes. It also offers detection of the two most common traffic violations: speeding and running red lights.

According to Dahua, of all the causes of traffic accidents, speeding has been the most common and predominant. In high-income countries, speeding contributes to about 30% of traffic-related fatalities, while it accounts for about 50% of road casualties in middle-income countries.

The Dahua Smart Traffic Management Solution has cameras equipped with automatic number plate recognition (ANPR) technology that capture both the plate number and time from the beginning to the end of the detection zone. The information is then transferred to the DMSS platform to evaluate the average velocity of each passing vehicle. The recommended distance is 2-5km, which yields to 99.8% accuracy rate. The margin of error decreases as the length of the detection zone increases.

For ease of use, Dahua offers portable and fixed installations for both point speed detection and section speed detection, allowing traffic personnel to move to different road points if necessary.

Red light enforcement is a crucial element in traffic management, with statistics suggesting that every year, 21.5% of all traffic accidents are caused by motorists running red lights.

At present, most red light enforcement solutions involve the use of underground sensors which carry various disadvantages (e.g. need to dig the ground to bury the sensor). Dahua’s Smart Traffic Management Solution, on the other hand, centres on video. At the core of this solution is a system that synchronises the status of red light signals with the trigger signal of the camera. When a violation occurs, Dahua cameras, like the ITC952-AU3F-LZF1640 model for example, take three images of the violation to be used as evidence: vehicle license plate, status of traffic light and an overview of the scene. The DSS management and storage platform collects these data from each camera and distributes them to client operators for further processing. Edge storage devices ensure that data are saved even when a power failure occurs.

For highways, flyovers or ramps

Observing proper speed and driving behaviour is a must, especially on critical zones like national highways, flyovers and ramps. The Dahua Traffic Management Solution has a varied set of intelligent tools to help in traffic enforcement. This solution can also detect phone using while driving, unfastened seatbelt, disobeying traffic signs, occupying emergency lanes, illegal lane changing, counterflowing, etc.

This solution supports multi-tracking of up to 6 vehicles at the same time, with detection range of 3m-100m and monitoring range of up to 4 lanes. And for scenarios that require long distance detection, it offers a 28MP dual-lens traffic camera with monitoring distance of up to 80 metres.

Urban areas

The Dahua Traffic Management Solution also provides large truck detection that can identify trucks that are forbidden on a monitored area (“red zone”) based on weight and dimensions, as well as specific time period. It also offers helmet detection, which can help ensure the wearing of a safety helmet whilst riding a motorbike.

In addition, illegal parking can also be detected from up to 200m (diameter) with only a16m blind spot area.

Global Applications

A city in Mongolia faced an increasing number of vehicles, which lead to a plethora of traffic challenges like lack of license plate recognition system, quality technical support, and cost-effective traffic solution. To help the city improve its traffic management, the Dahua Smart Traffic Management Solution was implemented, featuring violation detection, ANPR system, speed measurement system and command and control solution for the traffic centre. Altogether, Dahua has installed ANPR systems on 28 roads, violation detections at 8 junctions, as well as 2 mobile speed measurement systems and 15 high-spot PTZ surveillance cameras.

Furthermore, in Indonesia, a study has revealed that 61% of the people who were killed in road accidents were riders of two- or three-wheel vehicles. Not wearing a helmet and triple riding are the main causes of fatal accidents. Statistics have shown that wearing a standard motorcycle helmet correctly can reduce the risk of death by almost 40% and the risk of severe injury by over 70%. The Dahua Smart Traffic Management solution was deployed in the country to accurately detect riders who are not wearing a helmet and those carrying multiple passengers at the same time, helping to prevent accidents and to ensure road safety.
