–SPD-HARM, INC-ZONE, MMITSS, and SPD-HARM +
–Benefit of implementing applications
in isolation or in combination differs from one operational condition to another:
•On dry weather days, delay
reduced by 4% with SPD-HARM+INC-ZONE,
compared to 2.5% reduction
with only SPD-HARM and 0.8% reduction with only INC-ZONE
•On days with rain and low demand,SPD-HARM+INC-ZONE increased delay.
–BSM frequency is not always critical for the effectiveness of DMA applications – difference in impacts of 1s and 3s frequencies is minimal (less than
–Effectiveness of DMA applications reduces with
increase in latency - most of the benefits of the system disappear beyond 1s-latency.
–Level of penetration of technology is an essential factor in
the DMA application effectiveness
– MMITSS results in 13% reduction in
vehicle delay at 100% market penetration compared to the base case vs.
6% reduction at 25% penetration.
