My friend Michael emailed me these great ideas for bikeway signage by Joseph Prichard, something that Los Angeles desperately needs. The bright purple signs come in four different categories: Navigation, Caution, Connections and Points of Interest. This is already a great starting point, as the signs will be informative to people on bikes and in cars.
For drivers it makes it clear that a certain stretch of road is a place that must be shared with bike riders. While for bike riders they will hopefully feel safer riding as an area has been precisely mapped out for them. I also like the idea of signs leading to bike shops and bike-friendly places to eat as well.
