- Abstract: Greenhouse gas emissions have dramatically risen since the early 1900s with
U.S. transportation generating 28% of U.S. emissions. As such, there is
interest in reducing transportation-related emissions. Specifically,
sustainability research has sprouted around signalized intersections as
intersections allow different streams of traffic to cross and change
directions. Recent research has developed mixed traffic control eco-driving
strategies at signalized intersections to decrease emissions. However, the
inherent structure of a signalized intersection generates increased emissions
by creating frequent acceleration/deceleration events, excessive idling from
traffic congestion, and stop-and-go waves. Thus, we believe unsignalized
intersections hold potential for further sustainability improvements. In this
work, we provide an emissions analysis on unsignalized intersections with
complex, real-world topologies and traffic demands where mixed traffic control
strategies are employed by robot vehicles (RVs) to reduce wait times and
congestion. We find with at least 10% RV penetration rate, RVs generate less
fuel consumption, CO2 emissions, and NOx emissions than signalized
intersections by up to 27%, 27% and 28%, respectively. With at least 30% RVs,
CO and HC emissions are reduced by up to 42% and 43%, respectively.
Additionally, RVs can reduce network-wide emissions despite only employing
their strategies at intersections.

Our method is also robust against both blackout events and sudden RV percentage drops, and enjoys excellent generalizablility.
