Re: [sumo-user] level of service

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

Actually, when looking at multiple time intervals or only using a single time interval for the whole simulation it is sufficient to take the meanTimeLoss and look up the LOS in a table such as https://en.wikipedia.org/wiki/Level_of_service_(transportation)#LOS_for_At-Grade_Intersections

The formula only makes sense when looking at the timeLoss that has been accumulated in a particular interval but the meanTimeLoss within will also be included in the meanTimeLoss of a later interval (when the vehicle actually passes the intersection) so you will get an invalid increase in timeLoss if you add this up for multiple intervals.

regards,

Jakob

hello,

I have a question about intersection LOS . how can I calculate LOS in SUMO? I saw a formula in your discussion that calculate LOS based on a formula :

(vehicleSum  * meanTimeLoss + vehicleSumWithin * meanTimeLossWithin) / (vehicleSum + vehicleSumWithin )

can I use it to calculate delay at the intersection (using E3 detector) and after that calculate LOS based on HCM ?
