Re: [sumo-user] Build sub-scenario
If you load your flows into duarouter it will be transformed into the <vehicle><route/></vehicle> style (duarouter does not support flow output).
You could only post-process it with your own code to put all the edges back into the from/to/via format and re-aggregate the vehicles into a flow.

Jakob

Ok. Sorry for being unclear. Perhaps I should have posted a new question…

Anyways, I have written my own code to do the cutting of the routes. Now I was wondering, since my route definitions lack some edges in the ‘via’ list, if my route file could be repaired by duarouter and that the output is in the format:

<trips>

<vTypeDistribution id="vehType1" >

<vType carFollowModel="SmartSK" laneChangeModel="LC2013" id="veh101" lcStrategic="3... />

<vType carFollowModel="SmartSK" laneChangeModel="LC2013" id="veh102" lcStrategic="4.3208" lcCooperative=.../>

...

<flow id="5" type="vehType1" begin="0.001" end="10200" vehsPerHour="118.6931" from="163[0]" to="448" via="440 313 33.52 34 35 39 326 327 330 179 334 335[1].37.14 " departSpeed="max" departLane="free" />

<flow id="7" type="vehType1" begin="0.001" end="10200" vehsPerHour="104.6109" from="163[0]" to="184.339" via="440 313 33.52 34 35 39 326 327 330 331[1] 336 337 40 41 342 343 346 347 " departSpeed="max" departLane="free" />

...

For historical and practical reasons I would like to keep it in this format. Is this possible?

Yes. The format

<vehicle>

   <route/>

</vehicle>

is supported by cutRoutes.py

Is it possile to use duarouter to output a route file as below:

 

<flow id="5" type="vehType1" begin="0.001" end="10200" vehsPerHour="118.6931" from="163[0]" to="448" via="440 313 33.52 34 35 39 326 327 330 179 334 335[1].37.14 " departSpeed="max" departLane="free" />

 

I managed to get duarouter to repair my current route file (which looks like above and unfortunately many of the routes lacks a couple if edges in the ‘via’ list), but the output is then in the form:

 

    <vType id="veh269" length="4.36" minGap="2.00" maxSpeed="50.00" probability="0.00" speedFactor="1.10" vClass="passenger" impatience="0.50" guiShape="passenger" laneChangeModel="LC2013" lcStrategic="4.1278" lcCooperative="0.48756" lcSpeedGain="0.0086" lcKeepRight="10" carFollowModel="SmartSK" accel="5" decel="10" sigma="0" tau="0.75045" tmp1="2.116" tmp2="0.5111" tmp3="4.9532" tmp4="3" tmp5="30.2733"/>

    <vehicle id="100.0" type="veh269" depart="0.00" departLane="free" departSpeed="max">

        <route edges="36 436 37 168 169 304 172 309 310 132.0 132.155 137 135 134 138 139.0 139.34 140 141 142[0] 1072.0 1072.245 285"/>

    </vehicle>

cutRoutes does not consider the 'via' attribute. only <route edges="...."/>

If your routes have lots of via edges than the result of calling duarouter and sumo --vehroute-output will be the same. However, duarouter should be faster.

Hi,

 

Ok, thanks! Actually almost all routes are fully specified like this:

<flow id="5" type="vehType1" begin="0.001" end="10200" vehsPerHour="118.6931" from="163[0]" to="448" via="440 313 33.52 34 35 39 326 327 330 179 334 335[1].37.14 " departSpeed="max" departLane="free" />

 

But I guess the routes that lacks one or two edges in the via list is causing the problem.

 

Assuming I have an almost fully specified route file. Can I use either one of duarouter or sumo with option --vehroute-output?

 

Regards /Daniel

Hello,

cutRoutes assumes that the route file contains fully specified routes (with lists of edges) whereas your file only contains origin and destination.

To fix this, either process the route file with duarouter (giving you fastest-routes for an empty network)  or run it through sumo with option --vehroute-output (which gives you are more plausible route assignment based on traffic states).

Jakob

Hi,

 

I'm trying to build a sub model of a larger scenario but have run into trouble.

 

I have edited the original net-file with netedit and when I try to reduce the route file to fit the new subnet like this:

 

python "C:/Program Files (x86)/Eclipse/Sumo/tools/route/cutRoutes.py" -v C:/temp/SumoInputFiles/sumoNetworkEast_TL.net.xml C:/temp/AdditionalsRouteFiles/orgRoutes.rou.xml --routes-output C:/temp/test.rou.xml --orig-net C:/temp/SumoInputFiles/sumoNetwork_TL.net.xml

 

The output from this command is:

 

Valid area contains 331 edges

Parsing routes from C:/temp/AdditionalsRouteFiles/orgRoutes.rou.xml

Parsed 0 vehicles and kept 0 routes

Number of disconnected routes: 0. Most frequent missing edges:

Wrote 0 routes

 

Process finished with exit code 0

 

The route file (which I suspect might give me problems...) looks like this:

 

<trips>

<vTypeDistribution id="vehType1" >

<vType carFollowModel="SmartSK" laneChangeModel="LC2013" id="veh101" lcStrategic="3... />

<vType carFollowModel="SmartSK" laneChangeModel="LC2013" id="veh102" lcStrategic="4.3208" lcCooperative=.../>

...

<flow id="5" type="vehType1" begin="0.001" end="10200" vehsPerHour="118.6931" from="163[0]" to="448" via="440 313 33.52 34 35 39 326 327 330 179 334 335[1].37.14 " departSpeed="max" departLane="free" />

<flow id="7" type="vehType1" begin="0.001" end="10200" vehsPerHour="104.6109" from="163[0]" to="184.339" via="440 313 33.52 34 35 39 326 327 330 331[1] 336 337 40 41 342 343 346 347 " departSpeed="max" departLane="free" />

...

 

What am I doing wrong? Is the route file in a format not accepted by "cutRoutes.py"? is there an easy way of fixing this?

 

Regards /Daniel
