'Light Lane' es una propuesta para que una luz instalada en la bicicleta proyecte sobre el asfalto un carril bici "virtual" alrededor de la misma. El objetivo es aumentar la seguridad del ciclista ya que se ha demostrado éstos son más eficaces que la tradicional luz en la bicicleta

Light Lane - Concept from Altitude’s Alex Tee and Evan Gant

Published January 9, 2009 Altitude , Design Concepts

A close brush with a distracted driver is enough to intimidate the most avid bikers from riding at night. The problem isn’t just about visibility, as safety lights are effective at capturing the attention of a driver. However, these lights are typically constrained to the bike frame, which highlights only a fraction of the bike’s envelope. Bike lanes have proven to be an effective method of protecting cyclists on congested roads. One key is that the lane establishes 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, we shouldn’t expect to find them everywhere anytime soon. Instead of adapting cycling to established bike lanes, the bike lane should adapt to the cyclists. This is the idea behind the LightLane. Our system projects a crisply defined virtual bike lane onto pavement, using a laser, providing the driver with a familiar boundary to avoid. With a wider margin of safety, bikers will regain their confidence to ride at night, making the bike a more viable commuting alternative.
