fill_lanes exception handling incomplete

[keesvanginkel]

When calling load_network() for all roads, i.e. with keyword mainroad=False, the function fill_lanes is raising an error.

There is already some exception handling in fill_lanes, but apparently this is not complete yet.

Traceback (most recent call last):
