Required heap size for pt2matsim multimodal network #558

Open subrina0013 opened 3 years ago

subrina0013 commented 3 years ago

Hello I am trying to create a simple multi-modal network (car, transit) using pt2matsim. I have 16G in my pc and assigned 10G for heap memory. However, I am getting error as heap size is not enough. Can anyone please suggest me what should I do? Also is there any alternative to create a multi-modal network? Thanks in advance.

The memory requirements of pt2matsim depend on the size of the network you try to create. PT2Matsim will try to create a network covering the full region given in the OSM input data. So you could try to start with a smaller region from OSM.

Thank you so much for your reply. A smaller region works within 6G. My whole region is about 6,000 sq.mile. What should be the heap size for that? Is there any other way to do that?
