Good point!

Even if I were carrying a beacon as a rider, what if I forget to activate it? Or what if I lose the cell connection at a critical time

The Ridar system is based on a rider beaconing his presence and drivers being aware that a bike is in the vicinity and use caution to avoid colliding with it.  I'm sure it works well.  So, can we reasonably expect all riders to carry such a beacon?  Clearly no.  Therefore drivers must NOT rely on this method.  In other words, drivers are required to exercise the same situational caution as if the Ridar system is not in play.  So what's the point of the Ridar system in practice?  It really changes nothing in terms of how a driver should behave.  I believe the Ridar system is less safe because it invites complacency.

Just reposting the YouTube video on V2X for bikes for reference. 

https://youtu.be/S4n-t5-SJyI

Ridar solution is elegant and most importantly ready for mass deployment and adoption to start saving lifes! Nothing complex or too fancy that can become a distraction. No doubt there are concern of cellphone distraction. I'm sure riders who purchase and use Ridar had the sole intent to ride safe & be safe to other road users. With proper mounting it would mean it's part of the instruments cluster.

There are more development in this space in progress. Ultimate aim for such technology is to keep the road safe for all users. 

Now on the claims of V2V range of 100m with good line of sight is probably misguided. With good line of sight it can reach up to 2km and for Non line of sight about 80m. Realistically there should be sufficient response time in most use cases.

Regardless of which solution the ultimate objective is to create awareness by using cooperative driver/rider assist technology, which otherwise at this moment is mirrors, rider good judgement and a stroke of luck.

Hi Elizabeth,

The 10-second rule is only to initiate the technology--it won't turn off if you are riding under 10 mph. It will be designed to turn off after 10 minutes of non-activity/motion. 

The gyroscopic functionality is only built into more advanced cellular phones--if you're using an older or a "low end" device, the auto-start functionality may need to be initiated manually.

It is these and many other scenarios that we are considering before the actual launch of our product.

Thanks to you and everyone else that has voiced these concerns. It is these comments that will help us make a better product!

@ RidarSystems

Thanks for clarifying. It sounds as if you might be on the right path. I do have a comment however. In the article it says that the app only activates when you are going more than 10 mph and detects motorcycle/bicycle riders by gyroscopic lean. I see two potential issues with that.

First, there are many times when my speed on a bicycle is less than 10 mph (primarily when going uphill). I realize that you have to have a threshold but I hope that you keep the app active for some time after the speed drops. this would also help in those cases where an auto is stopped at a light and a rider comes up alongside from behind.

Second, the phone that I'm most likely to get as my next phone doesn't have a gyro... I suppose that's what comes of looking at "low end" smart phones

Thanks for chiming in, and educating us as to how this thing really works. Much appreciate your description here!

Unfortunately, the standalone features built into and being considered for vehicles of the future are good for line of sight and a distance of about 100m (V2V).

Ridar Systems looks beyond that  range of capability in order to prepare the driver with more of a 'heads-up', leaving more time for that driver to react.

Hello,

I'd like to address the comments that were posted to this article.

First, for anyone to fully understand how a technology works, one should ask before making any kind of assumptions.

With that said, here are the facts:
  • There is no need for drivers to focus upon their smartphones. The visual aspect that is displayed here is only for demo purposes. In actuality, the driver need only rely on an audible, "Rider ahead", "Rider to the right", etc.
  • Because the technology starts automatically, there is no need to fumble with one's smartphone, either when beginning a drive or while driving. The last thing we want to do is distract drivers any more than they already are.
  • Our intention is to implement this technology as both a standalone feature (using only one's smartphone) but also to be included with a standardized V2X solution.
  • There are certainly some areas of the U.S. and the EU that extend courtesy to riders (bicyclists & motorcyclists). This technology serves to simply make drivers more aware of a rider, whether they are courteous or not. Accidents happen, no matter how aware nor how courteous one might be.

As an example of this, there are approximately 122M motorcycles on the roads in the EU; in the U.S., there are approximately 8.5M. We have found that the EU are much more courteous to riders sharing the roads but that does not prevent the approximately 5,000 deaths each year in the EU.

By contrast, the U.S. has approximately the same number of deaths to motorcyclists--despite having about 14x fewer riders.

  • Battery life and data usage were at the top of our list when developing this technology. As this does not utilize a full mapping system, battery usage is minimal (as long as there is a cellular connection).
  • Yes, a bike mirror is probably the best defense for a bicyclist. But, even if you see traffic approaching, you still would not have enough time to avoid that car suddenly veering to the right (or, left).
  • When there are multiple motorcyclists/bicyclists, our system will treat those closely-aligned riders as a single notification.

There's much good that our technology can provide--and, it can reside in hardware that's already in the hands of most.

All we want to do is make drivers more aware of those most vulnerable commuters/riders who share the same roads.

I agree it could be useful to augment the performance of autonomous vehicles, but I would hope those vehicles have enough standalone detection/avoidance features to negate the need for potential victims to carry beacons to avoid getting hit.  On board tested and proven sensors and algorithms should trump a system based on third party devices, running third party apps, communicating with third party network services with known reliability issues.

Encouraging vehicle drivers to focus more on their cell phones seems to be exactly the thing NOT to do to reduce hitting and killing of cyclists and pedestrians.  Focusing on the road, being aware of other road users, and erring on the side of not hitting someone would seem to be a better approach.

As a motorcyclist, pedestrian and occasional bicyclist I completely agree that anything which serves to distract drivers from the road is a bad thing. On the other hand, something like this implemented as part of a V2X system for driver assistance/autonomous vehicle support could be useful.
