Abstract: The intelligent connected vehicle is equipped with advanced environmental awareness system and intelligent logic algorithm functions, and has environmental awareness and intelligent decision-making. However, the prediction and control of road blind spots is a barrier that can not be crossed by single car intelligence. At present, roadside sensing and vehicle networking technology has become one of the recognized technical routes for the development of driverless vehicles, road traffic safety and efficiency improvement in the future.Based on the standard sorting and visiting and investigating the domestic test sites and demonstration areas of the internet of vehicles,this paper puts forward the design method of road technical parameters and the design method of minimum communication distance based on the test scenarios, and proposes a design method of closed test site vehicle-road collaboration system in combination with the layout requirements of equipment and facilities, to meet the closed loop test and verification of the whole scene of the internet of vehicles vehicle-road collaboration.
