DynamicMap 2.0: A Traffic Data Management Platform Leveraging Clouds, Edges and Embedded Systems |
Abstract | ||
---|---|---|
Various embedded sensors such as LiDAR, cameras and GPS are mounted on vehicles today. And, vehicles with communication equipment can exchange sensor data between not only surrounding vehicles but also road-side-units. To achieve traffic safety and comfort driving, utilization of these traffic data are important for autonomous driving and advanced driving assistance systems. Our research group has been developing a city-scale traffic data management platform named DynamicMap 2.0. This paper proposes a software architecture of our platform. Our platform uniformly treats road maps, static information, dynamic information and predicted information. Road maps consist of three-level granularities: links, lanes and physical shapes. Especially, a data representation of lane-level road maps is newly proposed. Static information includes fixed properties about objects on the map. Dynamic information includes streaming data from sensors. And, predicted information is computed by prediction algorithms and simulations. Our platform provides query language for searching these traffic data. A developer of traffic applications writes a query (continuous query or one-shot query) which specifies integration and filtering of data. As a use case of our platform, we developed a prototype of a cooperative merging assistance system at intersections, and verify that our platform operates correctly. |
