Your next BMW may help you time traffic lights – CNBC

Posted: Tuesday, August 11, 2015

The Enlighten app is already available for iOS and Android smartphones. But BMW is going the next step. For Apple users, it has developed a system that can read the app and display it on your instrument panel – but only on cars equipped with the optional BMW Apps feature.

The display does more than report the obvious, that a light has turned red or green. Among other things, it will give an alert when the light is about to change. And it will predict whether you need to speed up or slow down to make the light. The BMW version of the EnLighten app is even smart enough to recognize when you have a turn signal on, so it can alert you if there’s a separate green arrow for a left turn.

The information is displayed on the multi-information display, or MID, in the center of the BMW gauge cluster.

Connected Signals claims to monitor “10,000 lights in over 100 cities and towns.” That includes some overseas, including stoplights in Christchurch, New Zealand. For the moment, the BMW version only works in three U.S. markets, Portland and Eugene, Oregon, and Salt Lake City, Utah. The company says it will be adding a number of other cities in the near future. (The standalone EnLighten app also functions in Las Vegas, and both Walnut Creek and Arcadia, California.)

There have been some questions raised about the accuracy of the smartphone-based system, and some reports have questioned whether EnLighten could prove to be a driver distraction.

But proponents contend such technology could smooth out traffic flow, save fuel and reduce the number of crashes caused by drivers racing to make it through a light.

Indeed, the basic concept could be integrated into the connected vehicle technologies now under development. So-called Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) systems will allow cars to communicate digitally with one and another and with a highway monitoring system. Among other things, this would provide a way to alert motorists to traffic jams, crashes and weather problems.

A major test program recently was announced covering more than 100 miles of freeway in metropolitan Detroit. And the National Highway Traffic Safety Administration is considering whether to mandate connected car technology in the near future. It is considered a critical step in the development of tomorrow’s autonomous vehicles.
