“SonarCycle” is a cyclist awareness App. The idea is simple. The application allows the cyclist transmit a "bluetooth" signal to vehicles around them to make them aware of a cyclist nearby.
Although the original idea was created on an iPhone the app could be run on Android or any other device capable of transmitting a “bluetooth” signal. The App uses high contrast black and white night time visibility for cyclists. It runs in the background of other Apps. The screen times out to save battery life and...
Regular cycling journey times can be stored so even if you forget to turn the App on, your phone won't. Timers can be set to cover approximate journeys. Destination coordinates can be accessed to remind the App to shut off when you arrive. All of these features to give the cyclist peace of mind and to save on energy consumption.
I chose the bicycle as a transmitter, because if the bicycle is the receiver it would more likely to receive multiple or confusing signals from the multitude of cars around them.

Bluetooth has a range of up to 100m.
