Intelligent Traffic

Innovating the traffic enforcement security system

As a system that has been proven to save lives, the Intelligent Traffic System (ITS) is widely deployed in cities worldwide. The traffic enforcement system is an important component of ITS, not only helping drivers to strengthen their awareness when driving, but also generating additional revenue from fines to help finance a sustainable, growing, and well-maintained enforcement system. The MSL Dahua Road Safety Enforcement Solution is a unique and comprehensive suite of tools which can detect multiple traffic violations in order to improve road efficiency and safety.

Speeding Detection

Most governments all over the world prioritise the improvement of road safety. One of the available tools for influencing the behaviour of road-users is traffic enforcement and in particular speed measurement. There are currently several ways to measure speed – section speed enforcement and point speed enforcement. Section speed enforcement, in contrast to point speed enforcement (for example, radar boxes) , has the advantage of measuring speed on a longer road stretch, preventing abrupt speed reduction at certain points. Point speed enforcement has the advantage of increased mobility so that traffic police can move to different points whenever necessary.

Features and Benefits

• Supports measurement of multiple vehicles in different lanes with high-precision 3D radar.
• In addition to speed, cameras can also capture details such as plate number, vehicle type, and lane number.
• High definition cameras can operate around-the-clock.
• Long battery life, touch panel, and compact design provide better on-site enforcement.
• Easy setup, instant deployment.
• Uses wired / wireless(Wi-Fi, 3G, 4G) network to forward data back to control center.

Real Time Traffic Status Display

Millions of people deal with traffic congestion on a daily basis. The roadways leading into and out of most major cities can become gridlocked due to accidents, road construction, or simply a high number of cars on the road.

Traffic Data Collection
Traffic data is collected by traffic flow cameras using non-intrusive virtual loops where detection is done through advanced computer algorithms and does not involve any road work as in the case of an inductive loop. It can cover 1-4 lanes at a time, and has a 99% detection accuracy at speeds below 80km/h.

Traffic Data Processing
An advanced traffic flow information analysis algorithm gets and analyzes a city’s traffic conditions in real time and displays results on special road signs in colors of red, yellow, and green to represent the speed of traffic flow. It serves as a guide to help drivers select the best travel route, easing overall traffic congestion.

Traffic Signal Control

Many signal controllers are unable to automatically adjust signal timing based on real-time traffic flows, which could lead to long traffic queues during rush hour, requiring more police resources to direct traffic.

The Dahua VACS Solution is a system that can extend traffic light intervals according to the detected vehicle queue length of road intersections. It adopts a traffic flow camera to detect information such as traffic flow, headway, average speed, occupancy, and queue length. It effectively improves traffic conditions by adjusting to make traffic clear faster. In addition, the system works independently and does not require a central software platform.

Traffic Data Collection
The collection of traffic data helps better manage traffic signals and provide for more efficient signal adjustments based on real traffic data. Traffic authorities can use real-time data to better understand current road conditions and enhance dynamic green light management, which can greatly reduce vehicle idle times. In the morning and evening rush hours, signal times can be adjusted according to actual conditions to provide more time for vehicles on busier roads.

Adaptive Signal Control
The traffic flow camera detects vehicles in pre-defined lanes and sends the length of vehicle queues to the controller through an Ethernet connection. The controller then triggers and automatically improves signal timings.
