Divided road can transfer more stuff quicker.
Long road can transfer less stuff quicker.
If you can ensure there is always something to transfer, you transport stuff quicker (because there will be no delays due to the worker walking back and stopping to the middle of the road).
If all roads are of the same length and there are more roads to everywhere to your lands than just one, then your transportation is already superior to what computer players are able to do. It is good to balance the traffic to multiple roads, because things get stucky if there is too much to transfer.
I tend to always use minimum length roads.
