That is another problem with road speed reduction based on 
unidirectional poi. (unless you make some workaround such as generate 
overlaying one-way streets for a workaround or whatever).

Simulation yes. Routing, no. For example, routing for a faster roads 
ignores mostly minor roads and seems to caltulate faster route based on 
what was not ignored. So, a major road with lots of traffic_calming and 
traffic_signals gets preferred. :(
