This year's Spring Festival is another Spring Festival under the normalization of epidemic prevention and control, and at the same time coincides with the Winter Olympic event, the flow and gathering of personnel have increased significantly, and the situation of epidemic prevention and control is grim, which has brought a complex test to the Spring Festival.

The Spring Festival is an "annual event" for the Chinese people, and has gone through more than 40 years. Safety and warmth are the people's sincere expectations for the Spring Festival under the normalization of epidemic prevention and control. The transportation industry not only aims at its own main battlefield to attack the stronghold, but also cooperates closely, and cooperates with the "one game of chess" thinking to do a good job in various tasks, so that people in the Spring Festival tide are safer and smoother, and the Memory of the Spring Festival is warmer and better.

The Spring Festival is still continuing, and people who have returned to work and school can jointly guard this "different journey" with the support of scientific and technological forces.

Before traveling, people can use scientific and technological means to understand the distribution of the epidemic situation and the location of nucleic acid testing in advance, and scientifically plan their travel. People can understand the distribution of the surrounding epidemic situation through Baidu Map's "Epidemic Community" thematic map; learn about the location and working hours of nearby nucleic acid testing service institutions through the "Nucleic Acid Testing" special map; and inquire about local epidemic prevention and control policies by searching the urban area of the destination to make various epidemic prevention preparations for travel.

During the trip, people can also use scientific and technological means to make travel more secure and worry-free. During the Spring Festival journey, using Baidu Map's future travel ETA, just set the departure time or arrival time, Baidu Map can gain insight into the road conditions during that period and accurately estimate the corresponding arrival or departure time. The cross-city public travel function includes all public travel tools, from going out to entering the door one-stop to meet the needs of passengers, so that people can carry their bags and leave immediately, and travel more smoothly. At the same time, the road weather navigation function of Baidu Map App allows users to view the road surface meteorological situation predictions such as low visibility, snow, ice, and water accumulation of the route when planning the route.

At present, the Spring Festival has entered the second half of the journey, and the return passenger flow has reached a peak at the end of the long holiday and is gradually decreasing. However, it should be noted that a new round of epidemics has recently emerged in Baise and other places in Guangxi, and there are still uncertainties in the prevention and control of the epidemic, safety emergency guarantee, road network security and transportation service guarantee in key labor import areas such as Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta.

The 2022 Spring Festival, a mobile China, carries vigorous vitality and vitality, reflecting a panoramic view of population migration full of temperature and "scientific and technological style".

Data description

Congestion index: As an objective indicator to characterize traffic congestion, it is calculated based on Baidu Map's massive traffic travel big data, vehicle trajectory big data and location positioning big data. The congestion index is the ratio of the actual travel time to the smooth travel time, and the larger the congestion index, the higher the degree of congestion.

Migration scale index: the overall migration scale is the whole country, and there is no distinction between moving in or out; the city level distinguishes between moving in or out.

Passenger flow index: the index value of the real-time passenger flow in the district and city, the larger the passenger flow index, the more passenger flow in the area.

Dining leisure travel intensity index: The indexation result of the proportion of travel behavior in the city's dining, leisure and entertainment.

Intra-city travel intensity: An exponential result of the ratio of the number of people traveling in the city to the city's residential population.
