Abstract
Recently, ITS services for next-generation, such as deviation prevention system at lane-level or autonomous driving, are making progress.
In this study, we develop an effective generation method for lane marking data by model-based approach using existing CAD drawings and road gauge type. Moreover we verify our generated data comparing with aerial survey product in three areas all over Japan. As for standardized artificial structure such as express-way, our approach, generating data with consistency by model-base approach and verifying, modifying generated data by fragmentary survey data, become very important in the sense of cost reduction and prompt generation/modification, though much survey data are required for high accuracy data until now.
