A Study of Specifications for Providing Lane-Level Traffic Information in Dynamic Maps

Abstract

For automated driving to be able to use lane-level traffic information, it will be necessary to verify whether or not there are problems with regard to the following issues: 1. errors due to data conversion in the multiple conversion processes conducted when providing traffic information, 2. differences in map accuracy, updating frequency and so on between the maps used for human drivers to provide route navigation and the maps used by systems, including automated driving, and 3. time lag at each stage in the generation, transmission and utilization of traffic regulatory information by the vehicle. A proposed testing plan has been prepared to conduct tests to verify these issues as part of a different project during the next fiscal year. In this study, an equipment configuration to receive the regulatory information distributed by road operators and overlay this information onto the dynamic maps was proposed.
