LightLane was originally created for a design competition by Altitude's Alex Tee and Evan Gant to promote commuting by bicycle. Although the concept did not win, the response was overwhelming, encouraging the inventors to continue development.
The LightLane device clips onto the back of the seat bar, uses super-bright red LEDs and two high-visibility diode-pumped solid state green lasers to project a virtual light path on the ground around the cyclist. The result is a recognizable boundary that's clearly visible to drivers but mainly at nighttime.
Bike lanes have proven to be an effective method of protecting cyclists on congested roads as they establish a well defined boundary beyond the envelope of the bicycle, providing a greater margin of safety between the car and the cyclist. Yet, only a small fraction of streets have dedicated bike lanes, and with an installation cost of $5,000 to $50,000 per mile, these lanes may remain rare in most cities.
The LightLane device is patent pending and has yet to become commercially available.
