Re: [sumo-user] How to get the mean travel time of the vehicles on a edg

[Zhiqiang Hu <hzq950419@xxxxxxxxx>]

Hi Jakob,

When I add the option "--tripinfo-output ","tripinfo.xml" into traci.start(), I got the file tripinfo.xml. But the format is different from the demo,it is something like this:

<?xml version="1.0" encoding="UTF-8"?>

<!-- generated on Wed Jul 18 22:40:14 2018 by SUMO Version 0.32.0

<?xml version="1.0" encoding="UTF-8"?>

<configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/sumoConfiguration.xsd">

    <input>

        <net-file value="data/cross.net.xml"/>

        <route-files value="data/cross.rou.xml"/>

        <additional-files value="data/cross.det.xml"/>

    </input>

    <output>

        <tripinfo-output value="tripinfo.xml"/>

    </output>

    <time>

        <begin value="0"/>

    </time>

    <report>

        <verbose value="true"/>

        <no-step-log value="true"/>

    </report>

    <traci_server>

        <remote-port value="35799"/>

    </traci_server>

    <gui_only>

        <start value="true"/>

    </gui_only>

</configuration>

What's wrong?How can I fix it ?

Best regards,

Zhiqiang
