Re: [sumo-user] Level Of Service HCM with SUMO

[Pedro Oliveira <pedro.engenhariae@xxxxxxxxx>]

Good morning!

The simulations present more complete results. At intersections, HCM considers only the "control delay" portion for Service Level purposes.

Sds,

edgeData-output (https://sumo.dlr.de/docs/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures.html) gives you

laneDensity as #veh/km/lane. It's straightforward to use this for looking up the pc/mi/ln thresholds from the HCM.

timeLoss is a good choice, but add the departDelay as well since vehicles accumulate timeLoss only after insertion and departDelay before.

To ensure realistic insertion capacity, see https://sumo.dlr.de/docs/Simulation/RoadCapacity.html#further_headway_effects

Goodnight!

I would like to check if anyone has already carried out any work on obtaining an HCM Service Level with simulation data.

I am developing a test of a simple (T) intersection to obtain the average delay of the intersection and verify if it is compatible with the TWSC methodology.

At first it seems to me that TimeLoss is the most appropriate for the delay parameter.

Has anyone already carried out this type of analysis?

In a first test I carried out on software that uses the HCM methodology, the results were not complete.

Sds,

Pedro Oliveira
