Re: [sumo-user] How to get number of lanes of an edge in sumo via traci

Quite so. But if you cannot use sumolib, you may still look through the list of *all* lanes in the network to find those that start with the same ID as the edge you want and then find the highest index..

Hi Jakob,

Thanks for you email. However, the traci.lane.getIDList()  will only prompt the total number of lanes in the network, but not the number of lanes of a particular edge. 

getIDList Get the IDs of the lanes in the network.

    IDList = getIDList() Returns a cell array of strings containing the IDs

    of the lanes in the SUMO network.

Do you know how to get the number of lanes of a particular edge?

Hello,

for static network analysis you are better of using sumlib (or sumolib4matlab). However, you could call traci.lane.getIDList() and check for the highest index of the form <EDGEID>_<INDEX> in that list (subtract 1 to get the number of lanes because it starts with lane 0).

regards,

Jakob

I browsed thro traci functions and I could not find a way to do so. How to get number of lanes of an edge in sumo via traci for matlab?
