+Using video to count cyclists researchers found protected bike routes increased ridership from 21% - 171%. Survey data
+data indicates that 10% of those riders came from other modes of transportation. Overall 91% of survey respondents from
+all modes, e.g. cyclists, pedestrians, and drivers, agreed that separating bike traffic from cars was desirable. Both
+cyclists and pedestrians said they frequent businesses more often after the bike lanes were installed.
+
+Researchers also found that
+
+* 96% of all road users believed protected bike lanes improve safety
+* 33% of pedestrians believed protected bike lanes improved their safety compared to 13% who thought safety declined
+* 25% of cyclists ride more frequently after protected bike lanes were added
+* the more physical separation between bike lane and traffic, the more positive the feedback
+* planters, flexposts, buffers, etc were all received more positively by road users than paint only designs
+* 3x as many respondents said protected bike lanes made the neighborhood _more desirable_ (43% vs 14%)
+* _20% of cyclists and pedestrians said they frequent businesses more often after bike lanes were installed_
+  * compared to only 1% and 6% said they went less often
