1. Background introduction
With the advancement of my country’s urbanization process, urban traffic problems have become a “urban disease” in many large cities. On the one hand, excessive private cars and official vehicles have caused congestion in the city, and on the other hand, vehicle exhaust emissions have seriously affected air quality. With the promotion and practice of the two-oriented society, the travel mode of “green travel, low-carbon and environmental protection” has become more and more sought after, and there has been an upsurge of building public bicycle rental systems across the country.
The public bicycle rental system has been very popular abroad, so it will certainly be popularized in China. Many companies and schools are now relocating to the suburbs to form industrial parks, university towns, etc. Therefore, it is inconvenient for office workers, students and other groups to go out. The introduction of a self-service public bicycle system can facilitate people to go to work, go out, play, go shopping, etc., and cycling is an environmentally friendly, fitness, entertainment, and noise-free travel mode, which is worthy of promotion. Self-service public bicycles are uniformly distributed by operators and installed in areas with a large number of users, such as bus stations, industrial parks, and school gates. The intelligent, unmanned and unified management through the integrated equipment management platform will be favored by people. .
