Hi Raheleh,

 

I think the reason is that you are missing the option „ --device.rerouting.period”, as it says in the Wiki: “Please note that if a vehicle gets a routing device only rerouting before insertion is active by default. In order to activate periodic rerouting en route set --device.rerouting.period.” (see https://sumo.dlr.de/docs/Demand/Automatic_Routing.html#options).

 

Regards,

Giuliana

Subject: [sumo-user] routing

 

Hello,

 

I have two questions please.

- I have a sumo configuration file like this: 

 sumo.exe --routing-algorithm HL -n ./Mtl.net.xml -r ./RoutingSim1.rou.xml --junction-taz true --device.rerouting.adaptation-interval 100 --tripinfo-output ./tripinfo.xml --vehroute-output ./vehroute.xml  --vehroute-output.cost true  --vehroute-output.route-length true  --duration-log.statistics true --xml-validation never --verbose true --device.rerouting.probability 1

 

RoutingSim1.rou.xml contains 10000 vehicles that depart at each simulation step.

In vehroute file, for some vehicles, rerouting have happened and log is like this:

     <vehicle id="186" depart="246.00" arrival="1141.00" routeLength="7659.49">

        <routeDistribution>

            <route cost="620.53" savings="0.00" replacedOnEdge="" reason="device.rerouting" replacedAtTime="246.00" probability="0" edges="665 664 663 662 661 55 54 737 3574 3575 3189 3190 2146 2147 2149 2351 2148 3388 3389 1347 2905 1344 1345 1346 1300 2328 2061 1355 3756 2920 3611 2329 2330 2914 2915 2916 2917 2921 2179 2923 2924 2815 2620 3033 1943 858 857 859 770 768 767 1042 769 753 884 106 3249 1551 3255 3253 3731 3732 3147 1440 2722"/>

            <route cost="602.43" savings="0.00" edges="664 663 662 661 55 54 737 3574 3575 3189 3190 2146 2147 2149 2351 2148 3388 3389 1347 2905 1344 1345 1346 1300 2328 2061 1355 3756 2920 3611 2329 2330 2914 2915 2916 2917 2921 2179 2923 2924 2815 2620 3033 1943 858 857 859 770 768 767 1042 769 753 884 106 3249 1551 3255 3253 3731 3732 3147 1440"/>

        </routeDistribution>

    </vehicle>

 

All routings have happened are like this. The saving is 0, Replacedage is empty and there is not a change in the route. As log file shows, there was some jam and I was wondering why rerouting actually didn't happen.

 

- Another question is: why I see different number of queries in the log file? I have 10000 vehicles in route file, but I've got different answered query number. 

 

HLRouter answered 9970 queries and explored ...

In another case, that the number of vehicles in route file is smaller( 1000) , I get a bigger number of (1004).

 

Thanks for your help.

Raheleh
