SMART's Inspire Mobility blog started in June. It is billed as "the official on-line innovations library of SMART (Sustainable Mobility & Accessibility Research & Transformation) at the University of Michigan".
The blog depends on contributions from readers, so head over there if you think you have a transport innovation to submit.
What is SMART? More information here. It also has a lively series of events and speakers and a useful e-newsletter.
I like their 'five themes' approach to 'sustainable transportation'. The diagram above is from the SMART website here.
