ET Meeting Slides


	The evaluation will be based on data from 178 vehicles that have data acquisition systems
	-The other 2,800 vehicles will log a limited amount of data on the DSRC device
	-There are 2 primary forms of DAS data, numerical, and video
	-Numerical data:
		-In-vehicle = data about the vehicle dynamics of the host vehicle, and driver input to the vehicle
		-External sensors = Radar, vision based ranging sensors, and lane tracking cameras. They provide information about the relative location of other vehicles and objects and location of the vehicle relative to the road
		-GPS data = you know what this is.
		-V2V = information about the vehicles that the car is talking to including (relative position, etc.) and data on the safety applications (when they provide alerts)
	-Video data: Cameras capture video footage of both the driver and the surroundings of the vehicle (forward view, side view, rear view). The video of the driver helps us understand how the driver is reacting to the applications and allows us to study driver behavior/distraction. The video of the surroundings helps us to understand the context of the driving scenarios and safety critical events.
	-All data is continuous. We are capturing data every moment these vehicles are on the road. (This is important to mention because a lot of field tests only save video data for “events” and we are keeping all of it)
	-We have estimated that we will collect over 200 TB of data during the field test. This is a liberal estimate, and it is dependent on how much communication we see between the equipped vehicles.
