Abstract:Transportation infrastructure is quickly moving towards revolutionary changes to
accommodate the deployment of AVs. On the other hand, the transition to new
vehicle technologies will be shaped in large part by changes in performance of
roadway infrastructure. This research aims at understanding the relationship
between AV technology and infrastructure performance, which leads to
revolutionary change in transportation infrastructure design in the both short and
long term.
For nearly a century, traffic flow in the roadway networks is operated purely by
human beings. Human’s reactions to preceding vehicles and side vehicles almost
dominate the driving behavior, which is to be replaced by vehicle
automation/communication in the future. The technology for autonomous and
connected vehicles is rapidly approaching the point of commercial
implementation. AVs are cars that can be fully controlled by computers, instead of
people, relying upon on-board advanced sensors and computers to observe and
interpret road conditions and determine a safe course of action. Connected
vehicles, on the other hand, receive data from other vehicles, or a central system,
that then instructs them how to operate safely. Generally there is a significant
developmental overlap between the two, with future autonomous connected
vehicles able to receive data from itself, other cars and systems, and capable of
driving themselves or accepting control from external systems. With an assigned
time and path, these lightweight, self-guided cars would proceed steadily through
crowded infrastructure without all the stop-and-go that chokes roadways and saps
fuel efficiency. Many of the enabling technologies, such as adaptive cruise control
and lane departure warning systems, already exist. We envision that the pathways
of AV and connected vehicle development are likely to converge in the long run.
This research uses ‘autonomous vehicle (AV)’ to represent ‘autonomous connected
vehicle’.
