Re: [sumo-user] What does 'pos' mean in statistics net dump?

Hi Camillo,

 

you can read in our docs about the attributes' meanings. The "pos" attribute refers to the distance from the lane begin. Generally the vehicle element is a child of the lane element the "pos" attribute refers to. It is possible to use it for traffic density purposes although there are other output options (e.g. edgeData). You'd still need to read the edge lengths from the network, e.g. by using sumolib.net (ref, doc example).

 

Best regards

Mirko

Hi SUMO team,

 

I just want to make sure I understand the meaning of this in the statistics net dump file.

 

<vehicle id="vehicle_1" pos="8970.47" speed="30.00" posLat="2.35" speedLat="0.00"/>

 

does 'pos' mean the position in terms of meters from the starting position? does this mean that this vehicle is at position 8970.47 meters from the starting point?

 

Another question is, is it possible to use the statistic net dump file to calculate traffic density at every timestep? How is this done?

Thanks,

Camillo
