Traffic Jam Assist

Traffic Jam Assist is a system which,
through confirmation of the condi-
tions by the driver, provides lane
keeping, accelerating/decelerat-
ing, stopping, and starting off sup-
port on some highways and
expressways. Also, in an emer-
gency, the system can decelerate
and stop, to help avoid a collision or
help reduce the impact of a colli-
sion.
