As we look for ways to reduce our dependence on fossil fuels and find viable transportation alternatives to the internal combustion engine, many urbanites are turning to that staple of bipedal locomotion: the humble bicycle. While rider ship is increasing every year, bicycle safety remains a huge issue: in 2007, 43,000 people were injured in bike accidents, resulting in 698 deaths. Though many cities are getting serious about making bike-friendly infrastructure changes, installing bike lanes is a costly proposition with a glacial pace of implementation. Enter LightLane, a safety concept from the clever designers at Altitude, Inc. The system projects a virtual bike lane (using lasers!) on the ground around the cyclists, providing drivers with a recognizable boundary they can easily avoid. The idea is to allow riders to take safety into their own hands, rather than leaving it to the city.
