On September 26, 2021, under the joint guidance of Professor Dingding Han and key project member Professor Qiu Song from East China Normal University, the Laboratory of Hypercomplex Network Science and Intelligent Systems conducted drone and Baidu crawler experiments in Wuxi, Jiangsu Province. This experiment marked a critical step in determining whether the two platforms developed under the National Key R&D Program could be practically applied.
Before departure, the team conducted thorough inspections and adjustments of the necessary equipment, including test flights for five drones and assessments of high-capacity flight battery endurance. Upon arriving in Wuxi on the evening of September 26, the team first surveyed the seven traffic intersections identified for the experiment. They refined the initial experimental plan based on the actual conditions at the sites and conducted test flights at each intersection to determine optimal heights and angles for filming. After the surveys, project leader Zhao Kaidi developed a more detailed plan for the drone experiment scheduled for September 27, including personnel assignments. Due to battery endurance limitations, each group was allocated three high-capacity flight batteries, with each battery capable of powering a 20-minute flight.
On the morning of September 27, team members launched drone experiments at different locations simultaneously, as planned. The primary objective was to capture traffic flow data at the intersections throughout the day and collect information on traffic signal timing. By the evening, the team had successfully completed the planned data collection for traffic flow during the 8:00–10:00 and 18:00–20:00 time periods and securely stored the data. Additionally, they recorded traffic signal timing at each intersection. The plan for September 28 was similar, with adjustments to the experiment’s timing. After consulting local residents and traffic police, the experiment was rescheduled to target peak traffic times: 6:45–8:45 and 16:45–18:45.

The team carried out the drone experiments according to plan, successfully completing all related tasks. On the evening of September 28, at 7:00 PM, the team embarked on their return journey, marking the successful conclusion of the Wuxi mission. Throughout the process, team members encountered and addressed various minor issues, gaining valuable experience through active communication and testing.

The second task during the Wuxi trip was the Baidu Maps web crawler experiment. The aim was to collect comprehensive vehicle data and traffic signal timing schemes for all roads in Wuxi to support the brain-like CPS traffic control system.
Project leader Yang Zhengzhuang dedicated himself to writing the crawler scripts, working tirelessly and with great passion, often sacrificing sleep. On the night of September 26, while other members were resting, he continued testing code until 3:00 AM. His dedication and professionalism greatly contributed to the smooth and successful completion of the Baidu Maps web crawler experiment.
