SOLAR-POWERED signs that tell passengers where buses are have been put into trial use at some stops in the Pudong New Area.

The signs have been introduced at stops on routes No. 961 and No. 798, according to Pudong Bus Co, which installed them.

Company executives said the boards have been embedded with an intelligent dispatch system, which can accurately locate buses through both GPS and short-range wireless transmission technologies.

They also said the signs can store energy and power themselves for up to seven days even if it rains.

The signs include the name of each stop a particular bus route includes. An LED light will come on when a bus is a few stops away. When the light starts blinking, it means the bus has left that stop.

The company said it will install the signs at more bus stops in Pudong. It also plans to upgrade the technology to offer more information such as traffic reports and bus arrival times.
