    In the mid-2000s, Waze Mobile co-founder Ehud Shabtai received a cutting-edge (尖端的) gift from girlfriend: a GPS. The expensive gift was supposed to be helpful. But straight out of the box, it was already out of date.

    Shabtai, a coding enthusiast, had an immediate reaction to reinvent. Shabtai's solution? To build an app. With 80 million monthly active users globally and nearly 400,000 superusers who function much like Wikipedia volunteer editors (editing maps rather than words), Waze Mobile caught the eye of Google as a revolutionary approach to navigation (导航).

    Acquired by Google in 2013, Waze's value mainly lies in its high rate of user involvement. Unlike traditional navigation apps that simply show directions, Waze asks its users to report accidents and other road conditions in real time, so other users can avoid the traffic by using an alternative route.

    The goal behind Waze's approach is an ambitious one: not just avoid traffic, but end it altogether. Waze is finding new ways to put its loyal and active user base to use to make that vision a reality, including a plan to make carpooling (拼车) cool.

    To be sure, traffic jams are troubling people all over the world. Waze has been quietly ahead of the game for some time. In 2013, when Waze was just a small digital-mapping business with limited resources it had something Google Maps and other competitors didn't: richer GPS guidance thanks to its stream of live traffic reports from users.

    These users were the basis of Shabtai's plan to solve for his GPS device's “silent” hardware: he grounded the app in software that could be perpetually updated by users, anywhere and anytime.

    Waze Carpool is going straight to the heart of traffic jams, trying to get more drivers off the road and into carpools. The app has already connected tens of thousands of rideseekers with drivers willing to ferry them along a shared route, and that trend could be the answer to a traffic-free future.
