Safe drive map concept for road curve monitoring

We present a technique for dangerous curve monitoring relying on the innovative concept of Safe Driving Map (SDM), a geo-referenced database with data about safe vehicle behavior in the monitored area, also considering different weather conditions. A vehicle's data are compared with the SDM reference and the driver is warned in case of danger. A road-side unit can also be set-up, collecting information from vehicles, thus signaling possible dangers (e.g., a vehicle stopped in the curve). A preliminary evaluation was performed by developing a scenario using the PHABMACS (Physics Aware Behavior Modelling Advanced Car Simulator) driving simulator.
