Dynamic Map Prototyping and Design, and Establishment of Data Linking Functions, Distribution Functions, and Updating Methods

抄録

Over a five year period, beginning in 2014, we deliberated the approaches to use in relation to dynamic map static information requirements, data specifications, preparation guidelines, and encoding specifications, as well as the location referencing methods used to link static information and dynamic information in the dynamic maps necessary for automated driving systems. Through the Large-Scale Field Operational Test (Dynamic Map), we conducted static information evaluation with the collaboration of test participants. Based on the evaluation results, we concluded that the essential features that make up static information are sufficient for use by automated driving systems. We also defined features for which there were numerous requests from test participants as quasi-essential features. Through this test, we found that road signs, road markings, and the like change over the course of three to four months afier dynamic maps are created, and we identified a need to organize approaches to updating static information.
