[sumo-user] Fw:varaible speed sign

[wangwenxuan <wangwenxuan@xxxxxxxxxxxxx>]

Hello,

     I want to achieve a function. When traffic incident happens, the traffic will be disturbed. To guarantee the safety level,  the TTC or other safety indicator need to be calculated, if it’s not safe, then the speed limit should be changed to improve the safety level.  So it means the speed limit are dynamically changed. I want to know whether VSS can achieve this function. Thanks a lot!

 

Best Regards,

Wenxuan Wang

Subject： varaible speed sign

Hello,

   When I  set the variable speed limit in sumo, the codes are :

<variableSpeedSign id="variableSpeedSign_0" name="vss1" pos="150.87,50.76" lanes="r1_1" >

<step time="200.00" speed="33.89"/>

<step time="400.00" speed="13.89"/>

</variableSpeedSign>

But it shows :

Error: attribute 'name' is not declared for element 'variableSpeedSign'

 In file 'vss.add.xml'

 At line/column 50/94.

But I have declared the ’name=“vss1”’. So could  you please help me to figure it out? Thank you very much!

Best regards

Wenuxan Wang
