What is the relationship between the three elements of transportation system?

Information, communication and integration. Information collection, processing, fusion and knowledge service are the core of intelligent transportation system. Whether it is to provide real-time traffic information of traffic network or to provide online information for making travel plans, its technology can make managers.

Three elements of road traffic: people, vehicles and roads. People (including drivers, pedestrians and passengers) and cars (including motor vehicles and non-motor vehicles).

Extended data:

1, people (mainly drivers). Drivers must have qualified operating skills, rich driving knowledge and experience, good habits and emotions, and abundant physical strength to avoid traffic accidents under complex road traffic conditions.

2. Vehicles (mainly cars). The vehicle should have good technical performance (mainly maneuverability and stability) to ensure flexible and reliable handling (such as starting, braking, steering and acceleration). ).

Vehicle control: refers to the system that assists the driver to drive the car or automatically drives the car instead of the driver. The system uses radar or infrared detectors installed on the front and side of the car.

It can accurately judge the distance between the car and the obstacle. In case of emergency, the on-board computer can give an alarm in time or automatically brake to avoid, and adjust the driving speed according to the road conditions, so it is called "smart car".
