New light system in Atlanta designed to help traffic move efficiently


Atlanta's traffic signals are so old that operators have to manually program the lights on site. That doesn't work in a bustling city. So the city is buying new lights, at $100,000 a piece, that will allow for a more efficient traffic flow. The new lights coordinate with cameras and metal detectors so they know how many cars (not to mention bikes and pedestrians) are present. As a result they can automatically prevent some backups, Marketplace reports.

A Denver suburb bets big on free Lyft rides to light-rail


Disabled transit customers who can't walk to transit stations typically use "dial-a-ride" services that are notoriously expensive for governments and inefficient for customers. Centennial, Col. is launching a pilot to give citizens the option of instead using free Lyft rides to get to and from the Denver suburb's light-rail station, City Lab reports.

It will need a more comprehensive approach to city planning, or else it will wind up with extensive transit infrastructure that goes unused, the Los Angeles Times writes. That means L.A. Metro will have to work closely with cities to invest in crosswalks and sidewalks and promote land-use regulations that promote walking

Bike-share trips become mesmerizing droplets of light in these animated maps
