As the commissioning for the toll collection system of the last lane finished, the main body of the upgrading and transformation project for Guangzhou Airport Expressway Toll Station was also completed. Under the quiet moonlight, the toll station looks like a sliver sleeve. Bright lights and tender moonlight intertwine with each other, bringing excellent driving experience and aesthetic enjoyment.

Established in 1999, Guangzhou Airport Expressway Toll Station has been in operation for over 20 years and serves 110,000 vehicles on a daily basis. It is an important tollgate in Guangzhou. With the development of economy and society, the original toll station structure and model can no longer meet the needs of growing traffic. Therefore, Guangzhou Communications Investment Group Co., Ltd. and eSurfing Cloud have joined forces to upgrade and renovate the Guangzhou Airport Expressway Toll Station, with a view to increasing the transportation capacity of the Guangzhou Airport Economic Zone and improving the intelligent level of transportation in Guangzhou.

Digital twin empowers expressway toll station, and the transportation service system evolves to the "smart" level.

In the process of upgrading the Guangzhou Airport Expressway Toll Station, the key is to improve the overall operational efficiency and intelligence level of the toll station. Guangzhou Airport Expressway, as a transportation hub among Guangzhou downtown areas, the northern part of Guangzhou and the new Baiyun International Airport, features dense traffic at the entrance and exit, so congestion frequently occurs during rush hours on both business days and holidays. In addition, the municipal road connected to the expressway exit is often under congestion, which further affects the passage capacity at the toll station and the airport expressway.

Targeted at these pain points, with the digital twin system as the starting point, eSurfing Cloud provides digital services for mainline toll station of Guangzhou Airport Expressway from many aspects. Without changing the physical world, digital twins can "clone" the virtual world that corresponds to the mainline toll station of the airport expressway, where innovative attempts can dramatically reduce the cost of trial and error.

3D modeling:

The airport expressway intelligent transportation system is connected with map data , which performs a 1:1 real-time twin reproduction of key targets including equipment and facilities, traffic flow, and key vehicles in an all-round manner.

Digital twin system:

The digital twin system supports the digital perception of the vehicle's license plate, model, toll deduction status, color, location, and heading angle, and can track and analyze key vehicles through macro, micro, and first-person perspectives.

Intelligent precise coordinate induction system:

The system adopts non-inductive traffic guidance to replace ETC boom barriers, which can give precise guidance and issue warnings to vehicles whose toll collection is not successful or abnormal, thereby improving the overall operational efficiency and intelligence level.

Low latency response:

The low-latency response of the system allows vehicle owners to obtain the information pushed by the system to the guidance screen in time.

Weather adaptability:

The system is fully adapted to the real environment of the expressway, and can be used in low-visibility weather conditions such as night and heavy fog.

Vehicle management:

The system can distinguish and display the vehicle information of each vehicle, guide vehicles whose tolls are not deducted successfully, and push the guidance information to the display screen.

In addition to the digital twin system, the Guangzhou Airport Expressway Toll Station also uses intelligent robots to identify vehicle information. In the toll plaza of ramp B at Changzhou Island Toll Station on Guangzhou Xinhua Expressway, a cute intelligent robot stands on the platform. When a vehicle enters the toll lane and the license plate is recognized, the intelligent robot says "please show the payment QR code". The owner can pay the toll by putting the payment QR code in the scanning area. The whole process takes less than half a minute, which is very convenient for passing vehicles.

In addition, the Xinhua Expressway, Beihuan Expressway, and Nansha Port Expressway have also piloted the ETC abnormality processing equipment, which allows owners to pay the toll on their own. When the vehicle could not pass the ETC toll lane, the driver only needs to swipe the ETC card on the abnormality processor according to prompts, and then pays the toll after the system reads the entrance toll station and other information. Zhong Yilin, Director of the Operation Control and Command Center, Operations Subsidiary, Guangzhou Communications Investment Group Co., Ltd., says that the ETC abnormality terminals can effectively improve the efficiency and security performance of ETC special condition processing and greatly mitigate congestion problems caused by ETC abnormalities.
