A multi-agent, in-vehicle database recorder system for supporting traffic hotspots detection, geographical representation and analysis

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.
