Re: [sumo-user] Need help with graphs

[Sumbal Malik <maliksumbal01@xxxxxxxxx>]

Thank you very much for your reply.

I generated the edge data with <edgeData id="dump_60" freq="60" file="edge_data.xml" excludeEmpty="true"/>.

But the output of the edge data shows left vehicles "0" for each time step.

<interval begin="0.00" end="60.00" id="dump_15">
        <edge id="E1" sampledSeconds="1422.00" traveltime="80.92" overlapTraveltime="81.36"
density="23.70" laneDensity="11.85" occupancy="6.38" waitingTime="0.00" timeLoss="140.73"
speed="12.36" speedRelative="0.89" departed="48" arrived="0" entered="0" left="0" laneChangedFrom="6" laneChangedTo="6"/>
    </interval>

Please find the attached configuration files.

Thank you

1. you cannot do this with fcd-output directly since you need an intermediate processing step to compute average speeds (fcd has no aggregation). You could plot edgeData 'speed' vs 'left' for this

2. as above. You need to program your own aggregation for this.

3. edgeData 'left' vs 'density'

Dear All 

I'm struggling to plot some graphs from the attached files. 

I would be thankful if you could share the script/commands to generate the graphs:

1. How can I plot a graph of average speed versus vehicles per hour using FCD output.

2. How to plot a graph of the average leader gap versus vehicles per hour using FCD output.

3. How to calculate the number of vehicles per time that pass through a given point and plot them versus density?

Thank you in advance.
