Abstract

This paper describes a global database recorder architecture following a multi agent system philosophy to provide a specific global database information service. The global database stores relevant vehicles information, related to trips data and risky situations occurred. Trip information and risky situations details (stored previously on vehicle's local databases) are gathered together and used to show traffic hotspots in a graphical representation. In our work, each vehicle has a local database managed by an on-board system. This local database is fed by a pre-collision system and a perception system that identify traffic hazards. The global database can automatically collect all vehicles' local databases and is then exploited for a novel report system that shows traffic hotspots as highlighted points in a geographic map.
