QUICK Response codes, or QR codes, are being introduced at some local bus stops on a trial basis to allow passengers to check the whereabouts of buses and the expected arrival time of the next bus.
Passengers can scan the QR code, a type of two-dimensional bar code, with their smartphones to get real-time information on upcoming buses in order to adjust their commuting plans.
Some found the information is not accurate after giving it a try.
"The last time I checked, the bus was one stop away, and now I'm still waiting, after waiting a long time," said a passenger surnamed Wang, who hoped to catch bus No. 64 on downtown Beijing Road W. When Wang's bus arrived, it was not the number given on the smartphone.
Major bus operator Shanghai Bashi Group said information may not be right during the test. In some cases, passengers can't access their routes. But the operator said in June, after the test is over, locals can expect to see the service citywide.
Despite some problems, several bus passengers welcomed the idea.
"Riders can be prepared while they wait once they check the real-time status," said a passenger. "If it takes too long, maybe we can choose other means of transportation."
The city first introduced such a service late last year, allowing nearly 90 bus lines in the Pudong New Area to be checked on a smartphone application.
