Device was dreamt up at 'hack day' backed by Honda - but it won't solve cycle safety issues on its own...

The developers of a simple transmitter that alerts lorry drivers to the presence of cyclists in their vehicles’ blind spots have been awarded £2,000 to help develop their idea, conceived during a ‘hack day’ organised by The Guardian and Honda’s Dream Factory.

The device, called Bike Alert, was one of four innovative ideas shortlisted following the hack day – which actually spanned a weekend – in November, organised by Rewired State.

Guardian readers have now voted it as the concept most deserving of the funding, which has been provided by Honda.

According to developers Sym Roe, Emily Christy, Matthew Applegate, Dr Kevin Fong, “Each bike would be fitted with a tiny transmitter uniquely encoded to only interact with the BikeAlert receivers.

“The receiver (in the vehicle) can see the signal and knows a bike is very close and potentially in a dangerous position.

“Sensors take over for further positional data along with integration with on board speakers for further positional information which crucially is not distracting for the driver.

“The receiver would also tie in with road accident data to provide simple but vital warnings to the driver.”

In theory, it’s a cheap and potentially effective solution that would go a long way towards improving the safety of cyclists around HGVs, but there are some caveats.

Dr Lee told the Guardian: “Once we pinpointed the HGV issue [the disproportionate amount of cycling fatalities resulting from cyclists being in the blind spot of a left-turning lorry], and realised that this is a long-standing problem, we thought, well, it shouldn't be too hard to come up with some way to solve this."

While Bike Alert is certainly a welcome innovation, with the combination of sensors on bikes relaying information to the cab a compelling one, it’s unlikely to “solve” the issue on its own.

After all, it is only one aspect of improving the safety of cyclists around large vehicles – sensors on lorries themselves, mirrors (whether fitted to the vehicle or at junctions), driver education, the design of road infrastructure and discouraging cyclists from riding up the inside of large vehicles at junctions, among other things, all have a part to play.

Moreover, such a device would need to jump through a lot of legislative and regulatory hoops if it were to become mandatory for lorries, as the developers hope might ultimately be the case.

That’s going to take a lot more than the £2,000 it’s won courtesy of the Guardian's readers.

Also, it would not only need to be adopted by HGV operators on a wholesale basis, but crucially would rely on drivers actually using it to be effective, which might well depend on the culture of the firm involved and the extent to which it promotes best practice in safety in the first place.

Finally, even if Bike Alert were to end up as a standard feature on new bikes in the UK, it would also rely on owners of existing bikes to obtain a sensor themselves and place it on their frame, and it’s debatable whether even a national awareness campaign would result in more than a tiny minority doing so.

We don’t want to sound unnecessarily negative – anything that helps improve the safety of cyclists on our roads gets our vote, and it’s telling that the team that developed Bike Alert saw the situation as serious enough to address it.

Sadly, however, the situation is unlikely to change overnight – and it’s going to take more than one product, however compelling, to help reverse it.
