Trip times, but how many trips were taken? Make the roads painful/expensive enough and the one car still using them will have a very quick journey. Conversely, filling up the bike lakes with lots of bikes will increase bike trip times. I prefer to measure the efficiency of a road by the number of people it carries across all types of vehicles. Bus lanes over bicycle lanes imho as buses can more more people per hour down a single lane than anything else.

That makes no sense: second hand effects are always weaker than first hand effects. Why would the cars not use the road if the journey is quicker?
