Abstract

The emerging vehicle-to-vehicle (V2V) communications standard can help prevent bicycle-vehicle collisions as well as bicycle-on-bicycle collisions. The idea described herein is to build a device that allows a smartphone to access the V2V network and this, in turn, will allow bicyclists to participate in the V2V communications network.

V2V smartphone safety system for bicycles 
 

Bicyclists are sometimes hit by cars and there are multiple failures modes that can cause these  bicycle­vehicle collisions. For example, the driver of the car may not be paying attention and, as  a result, fails to see a cyclist when he or she is turning, changing lanes, etc. Collisions between  bicycles and vehicles can also occur if the cyclist fails to see the vehicle which becomes  increasingly likely when the cyclist is moving to the left and has limited ability to see objects at  their sides and rear. Lastly, visual obstructions such as parked cars may lead to collisions as  visual obstructions make it difficult for the driver and the cyclist to see each other with enough  time to prevent a collision. 
 
The emerging vehicle­to­vehicle (V2V) communications standard is designed to electronically  inform vehicles of each other's presence. The V2V communications standard is intended to  solve bicycle­vehicle collisions (among other problems), but in a vehicle­on­vehicle situation. In  principle, the V2V system can be used by bicycles as well to prevent colliding not only with  vehicles, but also with other bicycles who are using the V2V system.  
 
The idea described herein is to build a device that allows a smartphone to access the V2V  network and this, in turn, will allow bicyclists to participate in the V2V communications network.  Smartphones would participate in the network as if they were vehicles and would announce their  presence to other vehicles and receive notifications when other vehicles are nearby. Bicyclists  could simply carry around their smartphones as they normally would and this could help prevent  bicycle­vehicle collisions.  
 
This device would require some additional hardware to attach to the smartphone and would likely  require an additional transceiver that is compatible with the V2V network. In addition, it may be  necessary to provide a larger battery that is atypical of smartphones and additional sensors  would need to be added to determine the smartphone (i.e. bicyclist) position to the accuracy  required by V2V. The V2V smartphone transceiver would be a separate piece of ...
