Closetbiker,

Cute graphic, but misleading. "heart attack is the biggest killer" is garbage in, garbage out. When you look at the numbers the heart attack numbers are low until about age 70 or 80+. All people die. All doctors have to complete a death certificate. Unknown cause of death is "heart attack". The problem with this approach is accidents, etc with higher rates in younger people, is not addressed because there isn't a good lobby for it.

Original poster,
I've looked off and on for several years. Excutive summary: no valid data available.

Rates of death/ year are low, in most years maybe about 100. No agency collects relevant data. The data that is collected is more day of week, time of day, which doesn't tell you much than many deaths are because of lack of lighting.

You can't find data on:
1. bike vs motor vehicle
1.1 impact from which side of bike
1.2 type of pavement: street, trail, residental, 2 lane road, 4+ lane road
1.3 speed limit at sight
1.4 traffic signal data: green, yellow, red light
1.5 sun glare as partial cause
1.6 motor vehicle not operated under control: i.e.,cell phones, DUI, etc
1.7 bike not operating according to rules of road
1.8 safety equipment/clothing used by cyclist
1.9 solo cyclist or group of cyclists
1.10 traffic volumn at time of "accident"

2. bike, solo accidents
2.1 running off road
2.2 equipment failure
2.3 road hazard causing loss of control


It would be great to have data, but until someone lobbies for it, or volunteers create own database, all data is
suspect and just hearsay.
