Ambulance Report, April 19, 2016

6:30 am, April 19, Stillwater, OK.
Mesonet data:  wind was out of the East (4), at 5.86 mph
(East wind did not influence bike velocity travelling south)

Bike ride began at 1416 W. Liberty and proceeded down W. Lakeview Rd.  Then proceeded onto Brooke Hollow Dr. to where it interesects with N Washington.  Once on N Washington, heading was south.  251 ft south of Brooke Hollow Dr. (83 feet south of W. Brooke Ln), I was struck from behind by a truck.  If the truck was travelling at 25 mph, it would have taken 6.8 seconds to travel from Brooke Hollow Dr. to the Point of Impact (POI, see diagram). 

For the truck, from the point where near level driving would have been achieved (see diagram, red line), a distance of of 572 ft would have been covered at 25 mph and would have taken 15.6 seconds.

The same 15.6 seconds (working backwards) for the bike would have put me at Brook Hollow Dr. (estimated speed of 11 mph, for a bike)When I got on to Washington Street, 0 to 11 mph in 2-3 seconds, 11 mph from there forward, where was the pickup?  ANSWER: 572.5 feet away from the POI.

From Brooke Hollow Dr. to the POI, at 25 mph took 6.8 seconds.  There is absolutely no way that he could not have seen me.  Also, he would have seen me, long before that (at least 200 feet north of Brooke Hollow Dr., or the point on the road where the road became perfectly straight).  This computes to 5.4 seconds (for the 200 feet) and 6.8 seconds (for the 251 feet) or 12.1 seconds TOTAL (to travel 451 ft at 25 mph).   


Distance from Brook Hollow Dr to accident location = 251 ft

25 mph = 36.7 feet per second
TIME elapsed = 6.8 seconds

Distance from Brook Hollow Dr to accident location = 251 ft

11 mph = 16.1 ft/sec
TIME elapsed = 15.6 seconds

At 25 mph (36.7 ft/sec) 15.6 seconds = 572.5 ft (away from POI)

Once moving from Brooke Hollow Drive onto Washington, travelling at
11 mph = 16.1 feet per second
TIME elapsed = 15.6 seconds
(driver of the truck, had to have seen me for this period of time, if he was paying attention)  15.6 seconds is a long time to be completely inattentive.

1.  First sign is on the west side of N Wahsington St, approximately 40 feet south of Brook Hollow Dr.  This sign was clearly visible, 211 feet before the POI (point of impact).  At 25 mph, from the sign to the POI would have been 5.7 seconds.

2. A total of 4 "SHARE THE ROAD" signs are on N Washington Street from Brooke Hollow Drive to the intersection with Hall of Fame.

where exactly is the bike lane if we have the 3 feet please, and riding on the right?

Stillwater Oklahoma:  This picture is on Washington Street, looking North.  The area marked as the supposed "bike lane" is not navigable.  If the next 3 feet constitute riding as far right as possible, and the "3-Feet Please" law from that point is enforced, the actual biking lane will overlap the center of the far right lane (4-lane street).

For a city that wants to be "bike friendly" where exactly is the biker supposed to ride?  The sidewalk is obviously an option, but untenable with runners/walkers/pedestrians.

A. Truck Speed: 30 mph, = 44 feet/second   (From Brooke Hollow Dr, to impact, at 30 mph took 5.7 seconds) (251 feet)
B. Truck Speed: 25 mph, = 36.7 feet/second (From Brooke Hollow Dr, to impact, at 25 mph took 6.8 seconds) (251 feet)

Bike Speed: 11 mph = 16.1 feet/second
Closing Speed (A): 19 mph = 27.8 feet/second
Closing Speed (B): 14 mph = 20.5 feet/second
