CUBE VOYAGER- SKIMMING

Hi Vishnupriya,
It looks like the network links are disconnected from each other and everything is returned a default 1000,000 value. I suggest checking the connectivity at each intersection. A quick way of debugging this to Build paths using GUI:

Go to Analysis > Build Path > enter the attribute used to build paths (like distance or travel time) > Done

Then, enter the origin/destination which includes zones or node numbers and click Display.

If its say No path, that means there is something wrong in the network connectivity and you need to fix the network. I think this is what is happening with your network at the moment. If it shows you the path, then all seems to be OK.

Could you please check this? I hope this helps.

Thank you.
Vipul

Thank you very much for your reply. I build paths as you suggested, as there are 5 zones I considered between 1-5 od pairs and except between same nodes (eg-1-1, 2-2) rest all displayed paths as shown in the image below.

Could you post the template script which you are using? And may be the output print file?

Thank you for your reply. I apologize for the delay in my reply. Here is the script file. I used the scripting application directly.

This template script requires that you have a TIME and DISTANCE attribute in your network. I noticed that you have a DISTANCE attribute in your network but not a TIME attribute. You need to add a TIME attribute with link travel time values to get the correct highway time skims.
