In the context of networked highway and V2X, it is particularly important to monitor and manage operation of the road network.

At present, video technology is the main way to monitor highway network and acquire traffic data and information as well. The characteristics of video technology determine that the detection of traffic events is not directly detected, which is highly susceptible to severe weather conditions and lighting conditions. Under the influence of weather, light, environment and other conditions, information errors will inevitably occur in the process of image processing. It is difficult to identify real-time traffic data of road networks operation situation. The false rate of the data and information reduces the efficiency of emergency warning and response, which result in traffic uncommon accidents.

Heyuan Technology's intelligent highway network operation real-time monitoring system adopts advanced automatic real-time radar monitoring technology, which can collect real-time and accurate traffic data 24 hours all day, and publish it on GIS map, combined with meteorological information monitored by the meteorological element meters, provide more comprehensive, timely and accurate real-time traffic data for the road network monitoring center. It has made up for the shortcomings of traditional means, realized the all-weather, all-day self-monitoring, as well as the data collection and processing capabilities, which truly achieved autonomous and intelligent traffic operation management.

Functional advantages of WSDR radar: 

1. Operation in full illumination, all-weather conditions, automatic incidents monitoring system

2. Low false alarm rate: < 1 in 24 hours under all-weather conditions

The false alarm rate is less than once in 24 hours.

Based on the pre-set customized rules, the software is able to automatically analyze and classify the real-time monitored incidents, and raise alarm on the traffic behaviors beyond the pre-set parameters.

Extremely low quantities of false alarm and false alarm frequency:

System monitoring performance

During the monitoring process, if the measurement result exceeds the threshold set in the system, the system will automatically generate an alarm:

The speed exceeds the threshold

Slow moving vehicles 

All thresholds are set when the system is installed and can be automatically adjusted according to traffic conditions.

3. Traffic incident detection:  slow moving, stopped, reversing vehicles, speeding, congestion, accident, etc

The system can distinguish slow speed, congestion, stop, reverse, speeding, congestion, accident and other incidents according to the alarm rules pre-set by the owner, where it is set according to the road design standards, actual requirements, and the actual installation conditions on the site, and trigger an alarm in real-time.

4. Intrusion detection in road: pedestrian, animal and debris are monitored

The system could monitor highway and tunnels in real-time, specifically pedestrians, animals, debris. They can be detected accurately, real-time and triggers alarm, based on a preset parameters, so as to avoid major accidents and the happening of the secondary accident. 

The monitoring diameter of the system for pedestrians is 700 meters, and the monitoring diameter for debris is 300 meters (depending on the actual installation conditions).

5. Pre-disaster warning

The abilities of tunnel operation safety environmental awareness and traffic incident emergency disposal depends on the perception of accuracy and real-time performance, whether it is a dark adaptation, adaptation to light the light conditions, or encounter any abnormal traffic incidents, such as vehicle breakdowns, stopped vehicle, pedestrians, or collision, congestion and other abnormal incidents, as well as smoke, fire emergency, the tunnel monitoring center will receive real-time monitoring and low false alarm rate, less than once in every 24 hours. 

In addition, the advanced omni-directional wide-spread millimeter-wave radar technology can be applied in this system to pre-warning the fire before the fire detection system’s sensor. Radar can raise the alarms on incidents such as slow-moving, stopped, speeding, collision, etc. these abnormal traffic incidents happened priory to traffic disasters, Where smoke and temperature sensors fail to reach the triggering point, the alarm could send to control centre, it provides the earliest time window to raise alarm, Radar could penetrate smoke, explosion and other visual invisible barrier, accurately positioning trapped pedestrian, vehicle status in real time and also provide the best solution for tunnel operation safety and emergency rescue.

6. 360 ° (1000 m diameter) full coverage

Each sensor is able to scan 4 times per second within the range of 1 km, 360-degree omni-directional monitoring, to cover the entire road surface and every aspect of each lane.

The system is a systematic scheme which combines visual technology with microwave sensor. The system can continuously monitor the average speed and frequency of vehicles to provide accurate traffic analysis data directly.

7. All-weather conditions and all-day working, with an MTBF 75,000 hours.

The system is not affected by any weather, light environment, including fog, smoke, storm, rain and snow, glare, and other circumstances, the monitoring function is not affected by any.

Traditional event monitoring is affected by adverse weather conditions, light conditions and extreme lightning conditions. The system can provide the best monitoring solution for the owners who need it most.

8. Road situation awareness under low illumination and invisible environment

Microwave automatic monitoring sensor can realize the real - time road surface awareness of the covered area.

When an accident occurs in the tunnel, for example, the traditional video camera incidents detection technology will fail in the high heat and smoking environment. However, the radar system in high-frequency microwave signals can penetrate the thickest smoke, locate trapped pedestrians and vehicles accurately, and within 10 seconds of automatic alarming.

9. intelligent road VMS automatic warning system

When any abnormal incident alarm is triggered, the system will publish information according to abnormal incidents automatically through VMS, VSLs, INFO signs, automatic warning send to drivers, which realize the dynamic control and induction of traffic speed, increase the road capacity, reduce traffic congestion, to prevent the secondary accidents and serial accidents. 

Practice has proved that using the system, could reduce at least 30% of road accidents, improve the traffic flow at the same time, thus reduce traffic pollution, improving comfort the equilibrium traffic flow, the timely delivery of information, reduce the driving tension, improve the driver's comfort, can also effectively upgrade the service level of transportation facilities.
