FiberHome’s Smart Traffic Solution for a Smarter City

With the rapid urbanization, city’s traffic development has always been the focus of attention.

The development of technologies such as big data, cloud computing, and artificial intelligence has made smart transportation todays the hottest trend. By integrating these emerging technologies, smart transportation supports the entire process of traffic management, transportation, travel, and other areas, enabling transportation system to have the ability to perceive, interconnect, analyze, predict, and control regional areas, and fully guarantee the safety of urban traffic, and improve the of traffic operations efficiency and management level.

There are many ways to transportation today. Bicycles, cars, public transport, and private cars and many others, but regardless of transportation mode there one scene you can never get rid of – waiting in traffic lights.

FiberHome’s intelligent traffic signal lighting solution relies on the intelligent transportation comprehensive management and control platform system as its core. The solution uses the video surveillance cameras to automatically collect traffic flow data and processes and analyzes the information through the big data management and control platform, In order to accurately obtain the traffic demand of city roads, and predicts the future traffic condition in advance, to develop the best timing plan for traffic lights.

1) Intelligent control and coordination
The Flexibility of the traffic signals give all-intelligent traffic integrated management and control platform with following advantages:
Intelligent road network interconnection monitoring. Smart traffic integrated management and control platform adopts advanced traffic optimization algorithms based on dynamic data and machine deep learning to ensure that the design time of each cycle is based on the optimal solution under the current information, and this algorithm considers the mutual influence between the time-sharing schemes at each intersection. With the concept of integrated thinking, the solution is different from the regional intersection adjustments that of the previous technical solutions. It reduces the total delay time of the entire optimized area through optimizing the direction and makes the overall road network traffic optimal.

Intelligent vehicle information recognition. Smart transportation integrated management and control platform can identify vehicle information (police cars, emergency ambulances, special vehicles, etc.) on its own, and can adjust the priority weightage of different roads according to requirements, thus optimizing the traffic signal timing plan in real time and promoting the improvement of road utilization, to ensure the smooth progress of the traffic plan.

Intelligent emergency fault-tolerant solution. In case if there is a loss of input data due to an accident, the intelligent traffic integrated management and control platform can generate suboptimal timing solutions based on historical data and synchronize self-checking, which has high fault tolerance and robustness.

2) Cutting-edge technology support operations
Relying on powerful emerging technologies, traffic lights can read traffic conditions, observe colors, and behave intuitively.
Big data collection and mining technologies. The data acquisition system can capture all moving objects in the video frame in real time, automatically and accurately, and collects traffic parameters (flow, speed, congestion, etc.) according to various categories such as large vehicles, passenger cars, non-motor vehicles, and pedestrians. Through collecting and aggregating traffic data from multiple channels, a unified data center is established and in-depth data mining and analysis are conducted. A stable regional traffic operation model is extracted from a large amount of historical data to accurately predict traffic conditions in the future and assist in the development of the best timing and road network management solution.

Artificial intelligence technology. Artificial intelligence has now risen to the national strategic level. smart traffic integrated management and control platform uses advanced convolutional neural networks, fuzzy logic and genetic algorithms to configure the optimal timing plan for the entire road network based on the collected real-time traffic information and highlights significant congestion areas through deep mining of historical data, self-learning through feedback information, and constantly improve timing plan.
IoT and Edge Computing Technology. Through intelligent transformation, it is ensured that each intersection becomes the nerve ending of the traffic management department, it ensures that traffic intersections have independent analysis and storage capabilities to enable remote sensing (video) and remote control. Specifically, each traffic intersection is a small control command center that performs local analysis and caching on video information received from all directions; For the control instructions issued by the center, local cache and execution are implemented to reduce information transmission and conversion, which greatly saves network bandwidth resources and improves system reliability.

3) Significant data measurement results
FiberHome intelligent traffic signal light solution has received strong support from Wuhan Municipal government. The construction of the intelligent traffic signal demonstration area has been completed in the Wujiashan area of Wuhan City, and with good operational results traffic congestion in the area has been greatly improve.

According to the data, the peak congestion in the Wujiashan area have been significantly reduced, especially during the morning and evening rush hour. The number of monthly congestion alarms dropped from 35 to 17, decrease of 51.4%. The average time for each alarm reduced from 22 minutes to 18 minutes, decrease of 18.2%. Delays have reduced significantly. The average daily delay time at each intersection in the road network decreased to varying degrees (3.1 seconds to 30.5 seconds). The average daily delay of the road network decreased by 17.8 seconds, which was 24% lower than the original plan. Taking the total number of daily trips at the road network intersection as estimated at more than 100,000 vehicles, the optimized timing plan reduced the total delay time by nearly 500 hours per day within the road network. Rush hour traffic was significantly increased. The most visible improvement was in the increase in traffic at the Sanxiu Road junction of Dongwu Avenue in the region by 15.8% (from 1334 to 1545 vph) at peak hours, and an average increase of 12.9% in all roads.
