If you want to get rid of any dependency on length, what about death per journey or per hour? That should give a "more correct" number according to your assumptions. Those statistics should also be readily available.

I agree anyway with @MikeB that "no other metric is significantly better, and all of them favour one mode of transport over all others". For example, if you consider the death per journey as I suggested, you have anyway somehow to consider that a typical journey via airplane would be much longer than a typical journey by car...

Maybe you could divide the death per journey via the typical journey's length.
