I was chatting with V the other day about motorcycles being allowed in London bus lanes, and how it's still only on a trial basis (even after two and a half years). Hopefully it'll be made a permanent arrangement, but while poking around the TFL web site I came across the study of the original 18 month trial. It's interesting (if dry) reading. Key points seem to be: 51% of motorcycles make legal use of bus lanes. 6% did so illegally before the trial began Motorcycles are significantly more likely to exceed the speed limit where permitted to use bus lanes Cyclists are 176% more likely to be involved in a collision, but it's often the cyclist's fault and rarely if ever due to the presence of a motorcycle in the bus lane. Indeed no statistically valid link was found between motorcycles being alloweed in bus lanes and cyclists having more accidents. Motorcycles are more likely to be taken out by a car turning left across the bus lane, but not by any significant degree (though that's not the spin they put on it on the TFL web site, which doesn't bode well). Pedestrians are generally safer than before. The conclusion's a little worrying though: "The effect of permitting motorcycles into bus lanes has been assessed after 10 months of implementation. This analysis period is the minimum where any reasonably large effects can be ascertained. This has identified that motorcyclists appear to be less safe since the scheme has been introduced. There were no changes in the safety of cyclists and pedestrians that could be directly attributed to the motorcycles being permitted access to the bus lanes." Hopefully the left-turn collisions will have reduced a bit over the second 18 month trial and they'll keep letting us use the bus lanes. It'll be a bit of a fucker having to go back to playing chicken with oncoming traffic twice a day.
