Safer roads to a sustainable future

Issue 7 2023 Surveillance

With the ever-increasing number of vehicles on the road, it is imperative to constantly improve the quality of transportation monitoring and traffic management in urban and rural areas. Dahua Technology released its Intelligent Traffic Solution to provide intelligent transportation solutions and smart technologies, enabling safer and more sustainable roads and ensuring people's safe and efficient journeys.

One violation enforcement unit integrates ANPR, traffic violation detection, speed measurement, traffic flow detection, driver behaviour analysis, and other intelligent functions to meet the needs of effective traffic enforcement in various scenarios.

Enhance 24/7 monitoring

Strong ambient light during the day can lead to insufficient illumination in the vehicle and a poor data acquisition rate. Therefore, supplemental illumination of the target is required while suppressing the ambient light. The SPC constructs an optical model by modulating the spectral channels and adding polarisers to capture violations inside a vehicle throughout the day effectively.

Moreover, Dahua also adopts an advanced GS-CMOS image sensor and high-performance AI processor, integrates deep learning algorithms, and upgrades image effects using Darklight technology. It realises clear and vivid images without colour deviation under ultra-low illumination, reducing light pollution, while improving the effectiveness of traffic enforcement and ensuring driving safety 24/7.

In addition, the RVF (Radar & Vision Fusion) technology enables a complete movement path of the vehicle in one visual display page. Traffic-related deep learning algorithms are used to capture vehicle metadata (e.g., ANPR, colour, logo, model) and to detect traffic violations (e.g., speeding, not wearing seatbelts/helmets, running a red light, etc.), with a capturing rate and accuracy rate of more than 99% and 98% respectively. Also, this solution uses the Doppler Radar that can cover 4,6 and 8 lanes (customisable) and detect up to 128 targets in a speed range of 5-300 km/h and speed measurement error of ±2%.

AI-based enforcement unit to minimise costs

The cameras can simultaneously support violation detection, speed measurement, and traffic flow detection, realising full-service edge intelligence in road scenarios. The number of devices is also narrowed down from at least 3 to 1. Moreover, the Dahua Intelligent Traffic Solution also eliminates the need for intelligent servers and transmission devices, which reduces the cost of constructing an intersection surveillance by at least 80%.

This solution offers an integrated all-in-one design to generate various products and meet various customer requirements. With fewer devices needed for traffic enforcement, this solution can significantly reduce equipment and installation costs and minimise carbon emissions and footprints simultaneously.

The Dahua Intelligent Traffic Solution integrates high-performance devices and management platforms with innovation and customisation to cover a variety of urban road traffic and smart parking scenarios such as intersections, expressways, bridges and city roads.
