As we look forward to the new year, we've also reflected on the old, and rediscovered some of the great events, innovations, interviews and debates that 2008 had to offer. For the next week, we will be sharing our picks from the Worldchanging team's best work from the last 12 months. Come back each day for a new collection of posts on topics from climate change to transportation, energy to health and society.

Today's Topic: Transportation

The way we get around impacts numerous other big-picture systems, including the way we use energy, the health of our bodies and our communities, the growth patterns that can protect or degrade our land, and our economy. For this reason, the transportation sector has always been one of our favorite places to look for new innovations. This year, we covered how these innovations, like bike sharing and bus rapid transit, have continued to become widespread and popular; and looked more closely at what transportation will look like in the future. Below is a collection of our best posts on transportation from 2008:
