Hi:
I am trying to estimate the intersection delay
for a simple intersection with one way major street (one lane) and one
way minor street (one lane).
I used E3 detector to get the
delay and compared the delay with the delay from the summary output and
with the HCM method (after estimated the critical headway (tc) and the
follow-up (tf) times for the minor street vehicles,which were in my case
tc=9.8984 seconds tf= 4.4464 seconds).
The delay from the E3 detector = meanTimeLoss="41.61" seconds
The delay from the summary output = timeLoss="216.28" seconds
(vehicleTripStatistics
routeLength="1345.30" speed="5.27" duration="313.33" waitingTime="0.87"
timeLoss="216.28" departDelay="122.52" departDelayWaiting="232.00"
totalTravelTime="277296.90" totalDepartDelay="135112.00")
Which value should I use when comparing the delay with the HCM? and why are they significantly different?
The example I used is attached.
Please note that I am using sumo Version v1_12_0+1571-290a748b45c under ubuntu 22.04 (development version).
Thanks,
