Mexico City is one of the most congested cities in the world. Traffic causes major economic, societal and environmental challenges for Mexico City and its citizens. This video looks at the traffic congestion issue in Mexico City and potential solutions.

Next time you’re stuck in traffic ground to a halt here in Seoul, think about this: as smart as our cars have become, our roadways are about to get a whole lot smarter. It’s certainly needed. Seoul is battling an increase in demand and an inability to build sufficient infrastructure to cope. Building new roads and new lanes often just isn’t possible any longer, but building intelligence into the roads and the cars—with roadside sensors, radio frequency tags, and global positioning systems—certainly is.

Smarter traffic systems can improve drivers’ commutes, give better information to city planners, increase the productivity of businesses and raise citizens’ quality of life. They can reduce congestion, shrink fuel use and cut CO2 emissions. Our rapidly urbanizing planet depends on getting people and things from here to there. In the 20th century, that meant freeways from one place to another. In the 21st century, “smart” traffic systems can be the new milestone of progress.

Let’s build a smarter planet.
