Transurbano
The Transurbano is a public bus system that serves Guatemala City. The system is operated by Siga, and funded by the government of Guatemala. The project was inaugurated during the administration of Alvaro Colom, and was supported by the Asociación de Empresarios de Autobuses Urbanos. The system was established with the goal of replacing privately operated bus service in Guatemala City, eventually amalgamating all urban bus services under the Transurbano umbrella. Service officially began on July 3, 2010, with 15 buses covering 3 routes operating in the southern part of the city between Zone 12 and Zone 21.
Phases
The system was launched in a series of phases, in order to manage rolling stock distribution and operations. Phase 1 was launched with services operating between Zones 12 and 21 in the southern part of the city. The system took advantage of the CENMA bus terminal to connect to Transmetro service. Phase 2 began shortly afterwards in February 2011. This phase provided more service to core areas of the city, including the historical downtown areas in Zone 1, Zone 2, and under served neighbourhoods in Zone 6, 17, 18, and 24. A majority of the bus drivers for the second phase were hired from private operators that were previously serving some of the target communities. The second phase was further expanded, and complimented with express services between Zone 1 and northern neighbourhoods, after the opening of Centra Norte in Zone 17. Phase 3 serviced the neighbouring city of Mixo, with one route providing regular service between Zone 7 and Mixco. This route was eventually taken over from SIGA by the Mixco municipality as they began operations of their Rutas Express service. Phase 4 was the last phase to start service and covered a number of under served zones, as well as provided local service connections to Transmetro Lines. This phase covers Zone 5, 13, and 15. Since the end of Phase 4, the network has merely focused on its original goal of taking over privately operated service in the city, replacing it with transurbano rolling stock and fare payments.Future operations
Due to the reduction in the gas subsidy for public transit operators, such as SIGA, various rolling stock owners and drivers have refused to provide service contracted by SIGA. Some have also chosen to raise fares or used cash instead of the SIGA smart card. This has resulted in a system that is unreliable and comparable to the previously existing model of multiple companies operating several routes. Fully publicly operated systems such as Mixco's Rutas Express, Villa Nueva's TransMIO, and Guatemala's Transmetro have seen success at providing safe and reliable public service at an affordable price. In 2017, the municipality of Guatemala considered a proposal to create a new alternative transit system to the Transurbano, under the Transmetro banner. This proposal would eventually develop into the TuBus system announced ahead of the 16th anniversary of Transmetro operations. This system is set to operate along a previously proposed Transmetro alignment between zone 17 and Centra Atlantida in zone 18, as well as zones 4, 6, 7, 9, and 14.Buses
The buses that made up the initial Transurbano fleet were made in Brazil by Busscar, Marcopolo, and CAIO. All buses featured informational LCD screens that displayed weather information and advertisements, security cameras, and GPS tracking. Since the completion of phase 4, SIGA has worked with private bus operators to convert and refurbish buses for Transurbano operation. Guatemala is a notable importer of decommissioned buses from the US. Historically, these have been decommissioned school buses that are transformed into chicken buses for rural passenger service. However, private sector importers have begun importing decommissioned low-floor city buses from the US, which are then leased to SIGA for Transurbano operations. The addition of decommissioned low-floor buses and low-floor articulated buses has also resulted in greater accessibility for users in wheelchairs or with mobility issues, and addressed overcrowding.Fare system
Fares are paid through a smart card, using RFID readers which deduct balance every time a user boards a bus. Fares initially were only GTQ1.10. However, the Asociación de Empresarios de Autobuses Urbanos, who initially supported the Transurbano project, advocated for the end of subsidies for bus operations, which would allow them to increase bus fares in both privately run routes and Transurbano. Fare increases must be approved by the government, and are closely monitored as a way to keep public transit relatively affordable, given there is no line transfer system, and instead users pay a fare every time they enter a vehicle. As of 2021, The smartcard for Transurbano is no longer accepted at Transmetro stations. Meaning riders must use SIGA cards for Transurbano, and Tarjeta Ciudadana for Transmetro.Routes
