Nexar Dash Cams Help Humanize Autonomous Vehicle Robot

released its Driver Behavioral Mapping data. The Driver Behavioral Map gives
insight for different road segments, driver types, weather, and road conditions.
Nexar's dash cams capture a wide range of crowd-sourced driving data of actual
human driving behavior, and are then aggregated and overlaid on a high
definition base map to be used for autonomous and assisted driving.
As local agents who have driven in an area know more than agents who have not,
either autonomous or human, AVs will use Nexar's real-time data to humanize
driving by training according to the local driving culture and mapping crucial
driving habits. AVs can use these maps to determine when to switch lanes before
a turn, how to decelerate when cornering, where virtual stop lines lay, and
"A self-driving car that drives only according to a raw map would be an
immediate danger due to its robotic style of driving," said Eran Shir,
Co-founder and CEO of Nexar. "It's not necessarily that humans drive better than
robots, it's that AVs need a lot of human data obtained by those who have driven
through a particular area. Without even being aware, we make hundreds of
decisions that adapt to local conditions, culture, and comfort each time we get
behind the wheel. AVs need to sync into this behavior in order to provide the
most secure and comfortable ride."
Nexar's Driver Behavioral Map accounts for speed distribution, acceleration
distribution, turn probability at intersections, switching lanes probability,
and virtual cross-walks, among many others. Providing a smooth and safe ride,
the behaviorally trained AVs will better understand, measure, and benchmark
safety-related behavior (stop lines, school zones etc.), as well as drive better
based on road conditions and visibility. Nexar's maps will empower AVs with
human driving behavior, while having the safety advances of a robot driver.
is used by both commercial and ordinary drivers, during all hours of the day, on
different road segments, and in all weather conditions," continued Shir. "There
is no more efficient or cost-effective way to collect this diverse set of human
driving data that is such a crucial part of our journey to advance a safe future
for autonomous driving. With the right data, an AV operating off of Nexar's
Driver Behavioral Map will continue on the road to becoming indistinguishable
from a human-driven car in terms of the flow of driving."
Cars outfitted with Nexar's smart dash cams drive over 160 million miles per
month, delivering valuable driving data all over the US. By accessing a
real-time record of how other vehicles drive on the same road segment at
different times of day, AVs can 'see' what's ahead, and make use of a map that
is constantly refreshed. The maps cover all 50 states.
