Description

Smart bus system and implementation method thereof

The invention relates to a bus system and an implementation method thereof, in particular to a smart bus system and an implementation method thereof.

In recent years, with the rise of environmental awareness, the issue of energy conservation and carbon reduction has sprung up. Among them, major cities have introduced supporting measures to replace self-use passenger cars with mass transit vehicles, and look forward to improving the utilization rate of mass transit vehicles, thereby achieving the goal of energy saving and carbon reduction.

In public transportation, the bus can be said to be most relevant to daily life. The known bus stop card usually only displays the bus line and the stop information through printed characters or display screens, so that when passengers wait for the bus at the bus stop, this situation often occurs. It is expected that the bus to be seated will not come for a long time. Choosing to take another alternative bus, but just taking the alternative bus, it is expected that the bus will arrive, causing inconvenience to passengers and thus reducing the willingness to take the bus.

Therefore, government agencies and manufacturers have proposed various diversified bus driving information systems, such as smart bus shelters and smart bus stops that can display the bus to the station, as well as bus routes and arrival information. Websites and mobile app software, etc., to increase people's willingness to take the bus. However, the existing bus driving information system cannot provide passengers for each bus, causing the passengers of the two buses before and after the passengers do not know that they are on the same route and arrive at the same stop. The former bus is fully loaded, and the latter bus is only loaded with several passengers. In addition, overcrowded buses can easily cause many dangerous accidents, such as stampede events, and easily detract from the life of the bus.

Therefore, the existing bus driving information system has always been unable to provide the passengers of each passenger of the bus, which is easy to cause the accident of the bus due to overloading. Therefore, it is necessary to propose improved technical means to solve this problem.
