Although much diminished from its past prominence, water-based transport still plays an important role in Bangkok and the immediate upstream and downstream provinces. Several water buses serve commuters daily. The Chao Phraya Express Boat serves thirty-four stops along the river, carrying an average of 35,586 passengers per day in 2010, while the smaller Khlong Saen Saep boat service serves twenty-seven stops on Saen Saep Canal with 57,557 daily passengers. Long-tail boats operate on fifteen regular routes on the Chao Phraya, and passenger ferries at thirty-two river crossings served an average of 136,927 daily passengers in 2010.
