Driven by economic interests, the long-distance passenger transport market generally has problems such as overcrowding, speeding, random loading and unloading, and fatigue driving. There are a large number of guests, and crimes such as theft and robbery occur frequently. At present, in response to problems such as overloading, speeding, and fatigue driving, the passenger traffic supervision department has formulated a number of rules and regulations, but lacks corresponding technical supervision methods. It consumes manpower and material resources, the degree of automation is not high, the management is backward and the detection accuracy is very low.

Literature [Remote Wireless Intelligent Vehicle Monitoring System. National University of Defense Technology Engineering Master's Degree Thesis. 2008.10] Using infrared beams to count the number of people getting on and off the bus, this method is susceptible to misjudgment due to the impact of passenger crowding; using GPRS to transmit vehicle passenger information and Car GPS information cannot upload in-car video in real time, and does not have fatigue driving detection and abnormal situation detection in the car.
