Studies show that when people can ride in a car without having to operate it, they increase their car use. That could increase traffic and pollution, unless government puts a price on car travel.
While the government continues to focus on building wider roads, most commuters in Nairobi rely on walking or public transport.

Left turns are dangerous and slow down traffic. One solution? Get rid of them. New research shows that limiting left turns at busy intersections would improve safety and reduce frustrating backups.
Cities around the world are reducing traffic speeds and improving access to local services and activities by public transport, cycling and walking. They are now reaping the many ‘slow city’ benefits.

An infrastructure boom threatens endangered tigers across Asia. Scientists want to know more about how tigers behave near roads so they can design wildlife-friendly transportation networks.
COVID-19 has underscored the value of parks and public spaces. A new survey shows that US mayors have gotten the message, but post-pandemic plans for public spaces remain largely undefined.
COVID led to commuting time savings worth over $2,000 a year for each driver and $5,000 per public transport user. But as workplaces reopen, we may need road user charges to keep traffic flowing.
