I'm sorry to hear that. I can confirm what Bertrand says: trucks and busses can cut you off if they don't see you; simply don't position yourself next to them; either move in front or stay behind them. 

I don't cycle much in Geneva but it annoys me to no end that bicycle lanes often just end or suddenly appear on the other side of the road. And tram tracks, watch out for those too.

This is very sad and I am truly sorry to hear about this tragedy.

The subject is something I have written about on here before. As a cyclist in Geneva, commuting from Carouge to Geneva most weekdays, I am appalled at the treatment cyclists receive from every other road users, including pedestrians.

I regularly experience cars accelerating hard to overtake me and then turn right directly across my path. Many drivers simply pretend they don't see me, even though I know they've just looked directly at me (this is particularly a trait of middle to old aged women). Many pedestrians go to step into the road, look up, see me, and just carry on as if I am not worthy of another thought. It's a sad fact that cyclists are at the bottom of the feeding chain in Geneva.

I'm very sorry to hear that, its very sad.

Ive actually just seen an accident myself, a cyclist lying in the road on the roundabout at ferney, intermarche. Hope both driver and cyclist are ok :( 

As a cyclist who hasn't had an accident in 18+ years in Geneva, I recommend following these tips for safety:

-Ride on the side of the road. Not 1m from the curb,where you will piss everybody off, but 30-40cm. This will leave enough space for drivers in a hurry to pass you. 

-Try riding at the same speed as traffic. If you go 10kmh and a car attempts passing you at 40kmh, it is a more dangerous situation than if you were going at 30kmh. The lower the speed difference, the better. 

-Avoid large, busy intersections with traffic coming from multiple sides (near train station), and avoid any area that looks unsafe (ex: around plainpalais). 

-Try to use car-less shortcuts. There's many bus lanes and parcs in Geneva which I use to avoid cars. I ride in traffic about 1/6th of the distance between Champel and Bel Air for example.

-Avoid riding at night, or when the sun is low. Even with lights on, drivers will not see you well. If riding at night, there's very few people out anyway, so you can ride on sidewalks. Cops are usually okay with it.  

-Avoid carrying any bags (other than backpacks, or when affixed on the bicycle) on you or the bicycle. A bag with a shoulder strap will slide off in case of a sudden movement, and make things worse. 

-Wear closed shoes. I see women riding with sandals / heels all the time, and that's just not safe. 

Also obey the traffic rules. Ive seen bikes jumping red lights when cars are coming all the time. They it will be your fault if you get hit

Yeah I agree. Crossing a red light is tempting, and I sometimes do it (when safe) but some crazy cyclists just keep going without even looking if there's something around the corner! Madness!

I commute 6000km a year on the bike, and suffice it to say, the general lack of any enforcement of any traffic rules just baffles me. Not to mention the blanted disregard for human life. I feel  I have seen everything.

The sad state of the biking infrastructure to me is not so much a political thing but an engineering problem. I mean, if you are going to build bike lanes, why not do it correct. It is not exactly rocket science....

Meet a dutch intersection. Bikes to right and separate traffic lights. SImple.
