Automated Driving
creating continuous detection of vehicles
and VRUs regardless of the time of day.
And in addition to better object detection, the artificial intelligence can provide warnings to pedestrians via external
speakers and lights, which are powered by
the Mobileye Shield+ onboard the vehicle.
New Flyer has also benefited from
increased computing power and pro-

cessing speeds to allow the vehicle's
controllers to process more information
and respond faster. This is because large
amounts of data can be transmitted from
the vehicle to or from its surroundings
thanks to telematics and cellular signal
processing, explains Burcar, who says
further advancements in this technology
and information connectivity will help

buses better navigate congested routes.
"If connected, the vehicle does not
have to drive itself all alone," Burcar
said. "It is best if it connects to both infrastructure and other vehicles to make
the best decisions of how to maneuver
safely through traffic. That connectivity
gives the vehicle a better picture of its
surroundings and helps to anticipate
problems, even with traffic flow."
But before vehicles can achieve true
connectivity with one another and their
environment, Burcar shares it is prudent
to start improving SAE Level 1 and 2
technologies: think basic functions like
lane centering and/or adaptive cruise
control. Once these are understood, the
information can be applied to the next
wave of ADAS technology.
"A whole sensor suite could be installed
on a bus including the ADAS controller
but still operate at SAE Level 1-2," Burcar
said. "However, all the data of how the
driver controlled the bus in various situations could be compared to how the ADAS
controller would have controlled the bus
to measure the anticipated performance
of the ADAS system. This knowledge can
then be applied to later ADAS development projects involving SAE Level 3-4."
And improvements in sensor technology have allowed ZF to improve its
advanced braking system from being able
to identify objects at the vehicle level to
being able to identify VRUs and independently brake when necessary. For example, external camera technologies used
on buses can better sense pedestrians and
warn drivers of potential collisions.
"The advancements we're talking
about today in systems' capabilities can
definitely assist with the safety and efficiency of the mass transit system through
increased penetration of vehicles using
ADAS and with connectivity with the
infrastructure and other vehicles to further advance Intelligent Transportation
Systems," Williams said.

However, implementing higher levels of
automation, and eventually widescale autonomous vehicles, presents several challenges, especially for the transit industry,
which often operates in complicated, urban environments, Williams says.
