High-definition-map-sensitive Chinese road typical characteristics
Aiming at the demand for building high-definition map model with Chinese road typical characteristics(CRTC),this paper starts from the demands of explicit and implicit road and traffic information for autonomous driving,and describes their commonality and difference that affect vehicle driving behaviors between China and other countries.The paper illustrates CRTC from four aspects including basic road network,road signal facilities,road traffic rules and traffic road conditions,then detail analysis of CRTC impacts on map element selections,road and traffic semantic descriptions,the associations and spatial relationships among different map objects are discussed.CRTC can improve modeling high-definition maps and enhance the fineness,the applicability and the security for path planning and local motion decision in traffic environment to promote the autonomous driving and intelligent transportation.
