Re: [sumo-user] Avoiding U-turns with duarouter

Hi Ion,

 

Connection-dependent routing is an open/unsolved topic since long ago. I think it may be preferrable to forbid access to U-turn connections before running duarouter. You can do that easily in netedit by first selecting all of them as written before and then edit access rights in the inspect frame for one of them. The settings will be applied to the whole selection.

 

Best regards

Mirko

Hi Mirko,

 

How can I configure the parameters in duarouter to avoid internal junction links, such as U-turns?

I saw in the duarouter documentation that it's possible to set weights for edges, but I didn't find anything about setting costs or weights for internal junction links.

 

 

 

Here is the data structure issue based on your previous advice:

                                    line                      line

connection:from23551989#3_0to-23551989#3_0

 

 

 

In the '--weight-files' FILE  option, can we define weights for connections? If yes, what is the format (type) of this file?

 

 

 

Best regards,

Ion

Hi Ion,

 

you can select U-turns in netdit and save the selection to a text file:

• choose select mode
• filter: connection, attribute "dir", value "t", click "Apply selection" button (t for turn, there are other values like s=straight, l=left, r=right)
• click "Save" button below to save the selection to a text file for further processing

sumolib allows as well to iterate through the network and filter connections by direction: sumolib.net.connection.getDirection()

 

Best regards

Mirko

Hi,

 

I'm wondering if it's possible to avoid U-turns in the routes generated by duarouter. I tried adding a cost to the connections in the network, but detecting U-turns was challenging. Could you provide some guidance on the best approach for this task?

 

Regards,

Ion
