Another study, this one from the Harvard Center for Risk Assessment, predicts that emissions from vehicles idling in traffic jams will result in 1,600 premature deaths and $13 billion in “total social costs” in the U.S. by 2020.
Such sobering statistics — coupled with staggering population growth that sends 60 to 70 million new residents to urban areas each year — have cities seeking transportation solutions. Some are finding them. By deploying advanced analytics and “smart technologies,” pioneering cities are demonstrating how to make mass transit more appealing and roadways less congested.
Given budget constraints, costly transportation overhauls rarely happen in a year or two. But even incremental adoption of smart technologies can help. Here are five examples.
