Re: [sumo-user] Error in duarouter
Dear Mirko,

Maybe you miss my e-mail.

Could you reply to my question:  Is there any function in python or other packages that can provide edge's reachable edges as sumo-gui show?

Best,
Yanglan

Dear Mirko,

This is very helpful! And my new question is do we have any such function in python or other package to provide edge's reachable edges? If we have such function, we can use it to generate valid origin-destination pairs. 

Thanks a lot!

Best,
Yanglan

Dear Yanglan,

 

all edges along the route have to allow the vehicle in question to pass, not only those where it departs and arrives. You can use a feature of sumo-gui to check where your vehicle can arrive:

  • right click on the start edge to open the context menu
  • choose "select reachable" ...
    • .. and the vehicle class of the problematic vehicle
  • the reachable lanes starting from the start edge are highlighted

 

Best regards

Mirko

Dear SUMO,
 
When using duarouter to generate routes from "od.odtrips.xml", it has problem like this:
 
Error: No connection between edge '-12184790' and edge '12182499#5' found.
Error: Mandatory edge '12182499#5' not reachable by vehicle '664'.
Error: The vehicle '664' has no valid route.
Error: No connection between edge '12189756#3' and edge '-12182716#3' found.
Error: Mandatory edge '-12182716#3' not reachable by vehicle '692'.
Error: The vehicle '692' has no valid route.
 
I don't want to use "--ignore-errors" in my situation. 
 
The network is generated by using netconvert from openstreetmap. And I also make sure all start edges and end edges in "od.odtrips.xml"  allow for vehicle type of "passenger".
 
I also check some trip, for example like entry "<trip id="0" depart="3720.0" from="12181485#0" to="59779571#4" fromTaz="4549.0" toTaz="4599.0" departLane="free" departSpeed="max" type="type1"/>". I check the two edges(from and to) in sumo-gui. It seems they are connected and I can find a route between them.
 
My question is: 
what may cause the error like this: "No connection between edge '12189756#3' and edge '-12182716#3' found." if two edges are connected by some routes in sumo-gui. Can duarouter consider the road type? like some roads allow vehicles to pass but others don't allow vehicles to pass? If duarouter already considers different road types, how to use it when using duarouter?
 
Thank you very much for your help!
Yanglan
 
 
"od.odtrips.xml" like this:

I want to know what
