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.
