European projection for network analysis

Discussion created by ethempekin on Aug 29, 2012

I have searched the forum about a question concerning projections.
For a European project I will start to use Network Analyst.
The main tasks I will be performing is to run shortest paths. I am using publicly available data which had GCS WGS 1984 projection. With this data I have created my network but had problems in calculating length. They were not correct.
At the end I have tried to work with a new projection (Lambert Conformal Conic).
Do you think this is a good projection? Or should I work with any other projection?
I also could not find an explanation why GCS WGS 1984 projected data did not work in the first place.

Thank you for your help in advance,
