With the acceleration of urbanization, taxis have become an integral component of public transportation. However, the operation of taxis involves multiple aspects such as passenger safety, driver behavior management, and traffic regulation, making the enhancement of taxi safety and service quality a significant issue. To address this, taxi monitoring systems have emerged and have been widely adopted around the globe.

Taxis typically utilize passenger vehicles as their means of transport. With the continuous advancement of technology and products, modern passenger vehicles are commonly equipped with a variety of video systems, such as reverse cameras, surround-view monitoring, and blind-spot detection. Building upon these features, and considering the public nature of taxis, we have focused on developing two core monitoring systems: driver behavior management and passenger safety monitoring.

1.Driver Behavior Management

This system primarily relies on DMS (Driver Monitoring System) and ADAS (Advanced Driver Assistance System) cameras. Given the limited space inside taxis, these two types of cameras are often integrated into a single device, saving space and facilitating installation. The DMS camera not only monitors the driver's state (such as fatigue or distracted driving) but also partially monitors the front-seat passengers, for example, by checking whether they have fastened their seatbelts or are exhibiting any unusual behavior.

2.Passenger Safety Monitoring

To comprehensively cover the passenger space, a small camera is usually installed in the rear passenger area to monitor the safety of backseat passengers. This design effectively enhances in-vehicle safety and provides evidentiary support in case of emergencies.

When designing and implementing these monitoring systems, it is imperative to strictly adhere to the laws and regulations of various countries regarding privacy protection and data security management, ensuring that the application of technology does not infringe upon the legitimate rights and interests of passengers and drivers.
