Atlanta’s reversible express lanes project opens

  

The I-75 South Metro reversible express lane project in Atlanta, (USA) recently opened along almost 21km (12 miles).

The Georgia Department of Transportation’s (GDOT’s) NaviGAtor software will monitor the express lanes and will help displaying current toll rates on changeable message signs and other messages such as comparative speeds, showing the current average speed along the corridor for the express lanes and general purpose lanes.

The idea behind reversible lanes is old, elegant and smart but not easy and not safe as expected to operate. One of the most iconic places where this operation can be seen is at The Golden Gate's, which debuted in 1963, made traffic jams rarer and less severe, although sometimes deadly. However, this debate is over with the "Zipper", as it can be seen in the video below.

With driverless cars almost here, will we see the blooming of these type of schemes?

big data and transport: telematics

Uber is currently releasing its new tool, Movement, in order to provide cities with traffic patterns based on millions of trips taken over time -where data is anonymised. The tool tracks how long it takes to get from one point to another, and how that changes depending on the time of the day, day of the week, and factors like road shutdowns or city-wide events. It also allows users to look at patterns over a period of time.

This service is similar to the one already offered by TomTom or TrafficMaster (UK).
