With the acceleration of the coordinated development of smart city infrastructure and intelligent connected vehicles, the rapid development of smart transportation, urban governance, 5G communication, driverless and other fields has made the phenomenon of complex poles and scattered boxes at traffic crossings. The systematic layout of smart city infrastructure and intelligent network equipment were accomplished by innovating the first “double intelligent standard intersection” design method of multi-pole integration, multi-sense integration and multi-box integration.The design concept has been implemented in the high-level unmanned driving demonstration zone in Beijing, and the integrated function of vehicle-road-cloud coverage has been achieved on urban roads within 60 square kilometers.
