The CityFix is an online resource for learning about the latest in sustainable urban mobility and planning. Launched in 2007, the site connects a global network of writers, urban planners, designers, engineers, and citizens who work to make cities better places to live. The blog is produced by EMBARQ, a not-for-profit program of the World Resources Institute that works to catalyze and help implement environmentally, socially, and financially sustainable transport and urban planning solutions.
