With the headline 'Cycle 63 times more dangerous to ride in the car of parents' media hunted many cyclists in the harness. Our overall reaction read in "Auto transport is dangerous." detranceara Also was surprised detranceara with the Cyclists' Let children more bikes! detranceara " .
A few days later we read thoroughly IBSR report by. Enough food for two additional blog posts on this subject. In another post we draw our own conclusions, but here we look at the figures on which was based the following message:
First of all, the report detranceara is nowhere, absolutely nowhere, talk of school children. Not with the bike, not by car. The report is actually a very general detranceara overview of casualty figures in Belgium. It is relatively short and works with only three variables: Age of the victim. Transport of the victim. Total distance (or travel time) per vehicle.
In this study all kinds of movements detranceara thrown in a heap and averaged. Dates of highways, regional roads and urban areas. Dates of commuter traffic and leisure trips. Dates of fast and slow cyclists. So you can ask serious questions about the relevance of these statistics are to pass judgment on a very specific case, such as children who commute from home to the school. Now, well, more on that later.
Further, the report using incredible number crunching to get his job data. Besides correction factors detranceara in calculating the victims was needed a suit acrobatics to calculate the mileage and travel time of each age group. This is the report itself underlined.
If you compare the figures, you actually get a factor of 63. Now, this table brings the relative risks compared to car drivers (1.0) into the picture. Bizarrely, detranceara there are two other tables (casualties / km and km / victim) detranceara based on the same data where the difference is a factor of 30 on the one hand and on the other 55.
It is clear that the lead very rough rounding detailed numbers to very different conclusions. Coincidentally or not displayed just the biggest difference in the press. We have the numbers but there comes into service as showing that the actual difference is a factor of 55.7x.
Indeed, we are talking about a risk per kilometer, what the risk factors still distorts because of the higher average detranceara speed of the car. As the report points out that this is the international standard, but to us it seems not appropriate to use these very general figures for a very specific scenario. Moreover, you run a risk as a driver to be seriously injured or slain. And this in the round trip, but we just ignore.
When you think about the situation commute to school, you often speak of a relatively short distance detranceara (urban) for children between 6 and 14 years. In such a scenario, the difference in travel time between car and bike is not particularly large. You may even quicker by bike.
So let's look at the risk you take per minute that you take part in the traffic instead of the number of kilometers you move. We compare the so-called presence risk between children who cycle and that passenger in the car, we're not talking about a factor detranceara of 55.7, but a factor of 15.7. Still high, but already a lot lower.
Now you can not deny that in the current context, as a young cyclist at risk. The risk to be ... at least to a cyclist casualties victim. That's another story. Conclusion
But unfortunately the damage has already been done ... The spectacular headline lingers. "Yes, but I've got somewhere read that cycling is still so dangerous sir." Cyclists, as I follow your blog and think, "of course that report nonsense! detranceara Suspicious motorists see their unfounded fear. The power of the press, the power of statistics and the impotence of the well-meaning man-in-the-hat ...
