Metrobus (Buenos Aires)
The Buenos Aires Metrobus is a network of dedicated separated lanes and stations for normal buses that serve the city of Buenos Aires, Argentina. Designed as a Bus Rapid Transit system, it mixes a few bi-articulated buses with conventional buses. The headway is the same as before the implementation of the system, and it lacks the brand of the network in the buses that use it, maintaining their previous branding as common bus lines with their own numbers. The service operates 24 hours a day and 365 days a year, with 2-4 minute frequencies during the day and 10–15 minutes at night.
History
The first segment of the network opened to the public in May 2011, and runs through the entirety of Juan B. Justo Avenue linking the neighbourhoods of Liniers and Palermo. This segment consists of 21 stations and has a distance of.The second segment of the network, opened on 24 July 2013, spans the length of the 9 de Julio Avenue, consisting of 17 stations running for.
The third segment of the network opened on 14 August 2013, and consists of 36 stops with a distance of. This segment runs through important arteries of the southern area of the city, bringing commuters back and forth from the southern rail terminal of the General Roca Railway to the city proper's borders. In parts of this segment of the network the bus lines merge with the general traffic and return to the dedicated lane afterwards.
On 9 October 2013, the Government of the City announced plans for the extension of the network, which will have a total extension of. When the network is complete, it will have a total of 7 lines carrying an estimated 1.2 million passengers per day.
The fourth line, Metrobus Cabildo, opened in June 2015 and connects Congreso de Tucumán with Vicente López in Greater Buenos Aires. This segment was originally going to be covered by Line D in its extension to the borders of the city proper, however the creation of this Metrobus means the line's extension will be unlikely.
An eighth line was announced in 2015 which would run from North to South in the West of the city, linking most of the East-West lines together. This line will most likely replace the planned Line I of the Buenos Aires Underground, while parts of the line will run underground and the buses that operate the line will be electric.
Juan B. Justo Line
The Metrobus Juan B. Justo was the first to begin operations, opening in 2011 and running down the entire length of the Juan B. Justo Avenue. It is long, has 21 stations and carries 100,000 passengers per day with a frequency of one bus every 2 minutes. It is estimated that the implementation of the Metrobus along the avenue has reduced bus journey times by 40%, while also providing combinations with lines B and D of the Buenos Aires Underground, as well as the Sarmiento and San Martín commuter rail lines.The same exclusive lane is utilised by emergency vehicles. The implementation of this Metrobus line was met with some criticism from shop owners along the avenue who could no longer receive deliveries during peak hours due to the lower number of lanes for regular traffic, something which has been remedied by having specific hours for deliveries. The segment also resulted in a 30% increase in bus travel as a result of the faster travel times and increased frequencies of the services.
9 de Julio Line
The Metrobus 9 de Julio is long with 13 stations and runs down the 9 de Julio Avenue, taking roughly the same route as Line C of the Buenos Aires Underground. It serves 11 bus lines and reduces bus travel time by 50% along the avenue. The main objective of this line is to join together the city's two busiest railway stations: Retiro and Constitución and to serve the approximately 250,000 passengers per day which use buses along the avenue, with a journey time of 15 minutes instead of the 30 minutes a bus took before the line was built.The National Government on the time criticised the line for overlapping with Line C of the Underground, however there is no evidence that passenger numbers on the line have declined. Similarly, during the construction of the line thereof were also harsh criticisms that many trees along the avenue would disappear, however the City has stated that after construction was completed, there were 550 more trees along the avenue than before construction began. In May 2015, two new 90 metre and 230 metre tunnels on the southern end of the line were opened. These tunnels go to and from Constitución railway station and are designed to decrease surface traffic in the area around the station, as well as reducing journey times on the line.
Sur Line
The Metrobus Sur was inaugurated in 2013 and joins Constitución railway station to the south of the city, ending at Puente Noria at the limit between the city proper and Greater Buenos Aires. The line has two branches, is long and has 37 stations. It connects with the PreMetro E2 at its General Salvio terminus, with Underground Line H at Inclán and Line C's Constitución terminus where it also connects to the General Roca Railway.A further combination with Line H will be at Saenz once the line is extended there, and a larger transfer terminal was opened there in March 2015, where it will also connect with the Belgrano Sur commuter rail line. The line is estimated to serve around 250,000 passengers per day, with its creation increasing ridership by 30% and reducing journey times by 15%.
Cabildo Line
The Metrobus Cabildo opened on 17 June 2015, serving as a feeder service to Line D of the underground at its Congreso de Tucumán terminus and making it the first Metrobus line to continue out of Buenos Aires into Greater Buenos Aires. with a length of with the intention to reduce congestion in the area with a great affluence of passengers boarding Line D, whilst creating a terminal at the limits of the city at General Paz Highway for passengers from suburbs in Northern Greater Buenos Aires, such as Olivos and Vicente López.This Metrobus line cost an estimated AR$ 265 million ARS to build and will benefit an estimated 200,000 people. Having a feeder service to Line D is something which had been discussed for many years, and at one point this was going to be done using a Buenos Aires PreMetro service with a new PreMetro Line D1, however the Metrobus ultimately proved the most appealing to city planners.
25 de Mayo Line
On 5 October 2015 the Metrobus 25 de Mayo was opened, being the first line to operate on an expressway. The line begins at the intersection of the Perito Moreno, Cámpora, Dellepiane and 25 de Mayo expressways and continues on across the 25 de Mayo before arriving in the vicinity of Constitución railway station and the Perito Moreno expressway where it provides access to the Avenida 9 de Julio, the Metrobus 9 de Julio and Line C and Line E of the Buenos Aires Underground to the north, and the Roca Line, General Roca Railway and Line C to the south. The line is expected to transport some 120,000 passengers daily.The line has significantly different characteristics to the rest of the network, consisting of a single six-metre lane in the middle of the 25 de Mayo activated only during rush hour and shared with emergency vehicles. The space used for the Metrobus between regular traffic was already in existence and no extra space was taken from the 25 de Mayo expressway, which continues to have four lanes per side, however additional tunnels and access ramps had to be built to accommodate the Metrobus. The lane is opened between 6 and 12 in the morning towards the city and then again between 3 and 9 in the evening with buses circulating away from the city centre. The line is also the first to accommodate the long-distance buses entering and leaving the city to and from Western and Southern Argentina, and these are expected to make up the majority of traffic on the line, while journey times for both long distance and local buses using this line are to be reduced by 50%.
Along with the Metrobus line, the construction of a second bus terminal to reduce the strain on the Retiro bus terminal is being constructed at the start of the Metrobus line, at the intersections of the Dellepiane and 25 de Mayo expressways, with the intention of reducing the quantity of long distance buses making their way into the centre of the city. At the terminal, the Metrobus will connect with Line E of the Buenos Aires Underground at a proposed new station, while the terminal itself is expected to open in November. Prior to the opening of the Metrobus line, a new complex interchange was constructed at the western point of the line, over where the terminal is to be located.
