Approximately 200,000 people use the city's public bus system daily. Some of the bus transportation system is operated by the city government, but most of it is operated by the private sector. This mixture of ownership has contributed to safety and traffic problems. In 2013, when the SITRAMS commences operation, it will resolve many of these problems. Bus rides typically cost between $0.20 and $0.25, depending on the route. The city government operates a free bus system for use by handicapped, elderly, and pregnant persons; this is the only such system in Central America.
