2011 V2I-Enabled Signal-Vehicle Cooperative Controlling
System Study
Study
highlights:
•IEEE
conference paper examined the potential of producing an optimal schedule for
traffic lights and an optimal
speed for incoming cars to minimize stops utilizing V2I communication with downstream intersection controller
•Purpose
is to minimize idling, reduce stop-then-start cycles, and improve
throughput
•Controller
communicates recommend speeds for approaching “smart” (i.e., V2I-enabled) vehicles
Findings:
•Using
“moderate” levels of traffic demand for a 100-second period, when compared to
the no-smart-car scenario,
the smart car simulation produced:
–5% reduction in average delay
–33% reduction in average number of stops
