BTV Winooski Corridor Bike/Ped Injury Rates Astronomical Compared to VT Downtown Roundabouts

Data from the Winooski Corridor Transportation Corridor reveals real carnage on Burlington streets in addition to the fatality recorded about every 5-6 years, the latest in December Jonathan Jerome, a pedestrian who died in a crash on North Avenue.
Based on five years of data through 2017, about 150 injuries occur each year on Burlington streets, three per week. About 50 injuries or one a week are bicyclists and pedestrians in roughly equal numbers and 100 card occupants or two a week. 
About 10% of all 150 annual injuries on BTV streets occur on North and South Winooski Avenues.  And 43% of all yearly crashes occurred at intersections.    On the 17 Winooski corridor  intersections 0.21 injuries occurred to bicyclists per year per intersection--no injuries in a half century have occurred at the six downtown VT roundabouts (Manchester Center, Middlebury and Montpelier).  A similar rate for Winooski intersections injuries per year--0.21 pedestrian injuries per year per intersection--occurred for the 2013-2017 survey period.  Comparison the Winooski 0.21 figure compares to 0.0032 injures per year per downtown VT roundabout.For car occupants the Winooski Avenues figure is 0.13 injury per year per intersection (2.8 injuries yearly 17 intersections).  
 Car occupant injuries for the 6 downtown VT roundabouts:  0.013 per year (4 injuries recorded total for lifetime of the six roundabouts through about 2016).
So on the Winooski Avenues, an injury occurs about once every two months--7.2 per year.  For comparison, the six downtown VT roundabouts record an injury about once a decade! 

In addition to crashes involving personal injury, the vast bulk of crashes are property damage only--about 1,200 average yearly, almost ten times the injuries, about 150, recorded.
These are metrics BTV Police Chief Del Pozo would likely love!
