Motorcycle Safety

A few friends and I have been working on an idea to help prevent motorcycle rear collision accidents. We are building a device to help warn riders when a vehicle is approaching too quickly from behind, as well as help catch the approaching vehicle's attention when triggered and encourage them to slow down.


In a nutshell, it works like this. On the one hand, a mounted sensor on the back of the bike will detect when a vehicle is approaching to quickly, then notifying the rider via a warning light from the dash/gauge cluster powerful enough to be noticed without taking your eyes off the road. On the other hand, once the device is triggered, the emergency lights (or additional warning lights attached on the bike rear) will activate, helping to catch the approaching vehicle's attention and encourage them to slow down.

If you have an opinion on this, I'd be happy to hear it. Also, we're mostly concerned with getting your opinion on the idea in general - don't worry about the technical aspects as of yet.

How about ...

..if the sensor, instead of activating hazard lights, activated a rear facing RPG launcher ? :winkie:

Rear end shunt

A laudable intent but the idea has flaws.

If a driver cannot see a motorcycle and rider directly in front of them no amount of flashing lights is likely to help.  A device that lets you know you are about to be shunted is probably ill advised.  The expectation that you are about to be clobbered will cause you to tense up.  Would you not be at less risk of injury of you are relaxed? 

From a technical viewpoint how would you deal with the issue that, if the sensor is set to detect the car far enough away to make any difference it will be going off all the time when riding in traffic?

Motorcycle Safety.

I think the increasing reliance on electronic sensors and microprocessors is a shame when people were born with perfectly adequate biological versions which they choose not to use. But I'd like an ejector seat so let's have it.

Part of staying safe on a bike....

is being aware of things around you ........ using mirrors is the normal way to check what's coming from behind........ although I suppose any help is always welcome.....

I would suspected

in the next ten to fifteen years all road vehicles will become aware of each other and will all space each other and not allow one vehicles to stray too close to another or two close to the centre or edge of the road, each vehicle's onboard computer will talk to each other and make judgements. The technology is already here, it's just a matter of time before all first world countries start implementing it and making vehicle manufacturers make it mandatory  :upset::smile

Modify it

to activate a cutting laser that punctures the radiator of a tailgating vehicle, and you will have something.

Well aimed

shot gun blast at the car tires from the rear should do the trick nicely. Only needs to be on one-side and the car will slew away from the bike.:biggrin:

I had

a car do this to me recently. I had a sensor which was active only during the window when I was potentially going to be rear ended. It was called a mirror and my eyes. I simply stopped where I wanted to stop but was ready to fly out of the way if required.


A device to warn me of such things will stop me doing this, just as a reversing sensor stopped my bloody dad from looking as he was reversing so when it failed, he hit something. We need less gadgets and better training. A sensor won't have you prepared to act, it'll just tell you as it's too late in that circumstance and frankly will make rely on it. Just like some people rely on ABS or traction control. Whilst those two are useful when used properly (as a safety net to compliment safe riding), a failure with reliance means you die. Looking means you're considering the risks and are prepared to act. To fail to look means it will take you unaware and remove your ability to react properly - a sensor which warns you means you're going to stop looking.

Also, technically speaking I feel the cost of this device will be very prohibitive given it has to calculate speed, distance, vector and then be developed to anticipate scenarios where those three elements combine to make an accident likely. It will still be inferior to a MK1 eyeball.


EDIT: these ideas of turning it into a point defence system are quite good though. I like. I would consider a directed EMP pulse to disable the target and cause enough engine braking to slow it down and increase the available reaction time. I would also consider a shotgun blast (or something similar to the trophy system on tanks) to eliminate the driver.

Volvo cyclist and pedestrian collision avoidance (among others).

As kcmc said, the technology is already here. In fact it will be in the cars, not the bike. Sorry but you're too late.
