由于我们的街道变得更加拥挤，堵车是不可能得到更多的容忍。The number of cars on the world’s roads is set to hit two billion by 2030 — double what it is today, and the number of traffic headaches will likely follow a similar trajectory. Navigation apps that promise to re-route drivers before heading into congestion could offer some help, but today’s versions are not up to the challenge. Existing solutions offer the same guidance for drivers going to destinations in a given region. Thus, these solutions tend to move congestion from one spot to another.

How can we incentivize individuals to share their data and even help researchers accomplish specific tasks?
