China News Service, Hangzhou, October 2 (Xi Jinyan, Xu Kelu) On the first day of the National Day holiday, travelers gathered together and Zhejiang expressways ushered in peak traffic flow. According to statistics, as of 16:00 on the 1st, the exit traffic of expressways under the jurisdiction of Zhejiang Communications Group reached 1.895 million vehicles. High traffic sections are mainly concentrated in the inter-provincial corridors such as Hangchang, Hanghui, Shensu, Zhejiang and Anhui, and Hangjin-Quzhou. Tourist sections such as the northern line of the Qianjiang Channel and the Zhoushan Cross-sea Bridge have obvious tidal characteristics. Zhejiang Communications Group conducted scientific research and judgment in advance and made careful arrangements to ensure smooth and orderly traffic on the road network.

One strategy along the way to make traffic flow "smooth"
At 8:55 on October 1, the long downhill section of the Wenzhou section of the Zhuyong Expressway occupied the road for rescue, and the Taizhou section near Gongmenyan assisted in the implementation of main line checkpoint control. Behind the bayonet, signs of congestion began to appear. The Xianju Rescue Brigade immediately issued an order to lead the vehicle. A police car and a rescue vehicle led the way. The traffic flow followed closely behind and followed up in an orderly manner. The loudspeaker of the early warning vehicle constantly reminded "keep the distance between vehicles, turn on the double flashers, and follow the guidance." The monitors kept a close eye on the traffic flow behind them throughout the process and adjusted the driving rhythm in real time through the intercom to ensure that the fleet kept up with the formation and passed safely.
In view of the actual situation of the superposition of passenger flow in scenic spots and high-speed traffic flow during holidays, Zhejiang Transportation Group adheres to "one policy along the way, one point and one method" and implements precise policies around preventing backflow, tapping potential, controlling merging, and strong diversion: linkage The public security traffic management optimized signal timing, deployed more guides, and added turn lanes to prevent traffic from backing up the main line; the Quzhou section of the Hangjin-Quzhou Expressway dynamically opened hard shoulders from Lutangjiao to Wuli hub to improve traffic carrying capacity; Hongken, Dangwan, Convergence areas such as Wangjiabu, Chengcun hub, Yuhang, and airport interchange implement dynamic channelization and trickle release to balance the main line traffic flow; Hangzhou-Huizhou Expressway relies on data sharing between expressways and national highways to guide local vehicles to use the road, and Hangzhou-Jinqu Expressway The Quzhou Expressway relies on diversion points to guide vehicles around, and the Binhai Hub of the Hangzhou-Ningbo Double Line has established a four-level progressive mechanism of "open hard shoulder-merger warning-diversion guidance-block control" to provide early warning forces to prevent the spread of congestion.
Power in the front makes rescue "quick"
At 10:13 on the 1st, a small vehicle suddenly broke down on the 75K+400 section of the Shanghai-Kunming Expressway and was unable to drive. After the abnormality was locked, the monitoring center promptly reminded the driver and passengers to evacuate outside the guardrail. Rescuers Gu Chao and Xu Yuefeng arrived at the scene only five minutes after receiving the order, carried out safety control, checked vehicles and carried out rescue operations. Seeing that the accompanying children were slightly uneasy, the rescuers sent out small red flags prepared in advance, and the anxiety of the driver and passengers was relieved.
The relevant person in charge of the Operation Management Center of Zhejiang Communications Group said, “Before the holiday, Zhejiang Communications Group conducted in-depth analysis of rescue operations and road network operation data over the years, combined with the spatial and temporal distribution characteristics of traffic, accurately located high-risk rescue points and key sections prone to congestion, and promoted the construction of "Follow the data and report on hidden dangers" to save resources. Relying on the intelligent dispatching mechanism of "one event, one push, one node, one early warning", Zhejiang Transportation Group implements dynamic monitoring of key road sections and prone to congestion hubs to achieve a closed-loop process of accident discovery, order dispatch, disposal, and cancellation.
In the sections prone to traffic jams from Shangxi to Pujiang in Hangjin Qu, and from Jinhua East to Jinhua, small loops of police-enterprise joint patrols will be implemented to provide timely intervention. In the key sections of the Lin'an Tunnel Group, a full-service closed loop of traffic monitoring, intelligent early warning, emergency response, and remote diversion is fully implemented: relying on the front-end deployment of rescue stations to achieve quick arrival and efficient evacuation of accidents, minimizing the length of road occupation; comprehensive use of visual guidance, voice warnings, on-site channelization and other management and control methods to reduce minor accidents such as sudden braking and scraping from the source, and effectively reduce the risk of secondary congestion.

On the first day of National Day, Zhejiang Communications Group deployed a total of 486 rescue stations (94 more than usual), 3,729 security personnel (952 more than usual), and 1,197 rescue vehicles (359 more than usual). Equipped with 98 sets of drones and 1,137 sets of directional horns, as of 16:00, 1,124 clearing and rescue operations had been carried out.
Accompanied by service to “warm up” the journey
Zhejiang Communications Group has set up convenience service desks at various toll stations along the lines, equipped with hot water, first aid medicines, simple maintenance tools and other items, and providing services such as road condition consultation and ETC processing. Some stations promote local cultural and tourism information to make people's travel more comfortable and convenient. With the theme of "Celebrating the National Day, Zhejiang and Li are with you all the way", the Douyin platform of "i on Zhejiang Expressway" also launched a special live broadcast of National Day. The live broadcast room cooperated with Jiangsu Expressway and Anhui-Mei Expressway to carry out a joint live broadcast of the Yangtze River Delta. The anchors of the three places connected to introduce key inter-provincial corridors and Traffic conditions in popular travel directions, real-time broadcast of traffic flow changes, traffic control, slow-moving sections and service area information on the road network under its jurisdiction, timely response to travel inquiries, and provision of off-peak travel and safety tips, so that drivers and passengers can feel warm escort during holiday travel.
