Recently, there’s a special line added to the bus network of Suzhou: the 502 “major stops” line. Different from the normal 502 Bus route, this line only stops at over 40% stops of the normal one. After a short run-in period, the “major stops” line has won unanimous praise of the passengers. According to Suzhou Municipal Bureau of Traffic and Transportation, 502 “major-stop bus” is the first “major stops” line. Its inception comes from the “big data” of Suzhou public transportation which was accumulated to some degree.
