In recent days, D\u00e1vid Vit\u00e9zy, minister for transport and investment<\/a>, signed the European Union grant agreement worth HUF 32.2 billion for the second phase of the interlinked tram network in Buda, essentially setting the direction of transport development in the capital for the coming years. By coincidence, almost at the same time the International Road Transport Union (IRU) published an overview of Bus Rapid Transit systems, or BRT for short, which serve in many cities around the world as a more affordable alternative to rail transit. Below we review that article, supplemented with our own experience and numerous additional details and points of interest.<\/strong><\/p>\n

In this article, we will be dealing with genuine BRT systems, ones that comply with the relevant standard<\/a>. In other words, we are not concerned here with vehicles offering a higher-than-average level of service and\/or dressed up with an eye-catching design package while still operating regular bus services, nor with the feeder routes serving outer districts that Mayor Gergely Kar\u00e1csony announced under the \u201cmetrobus\u201d label, initially intended as attention-grabbing<\/a> and then, following reactions and misunderstandings, quietly dropped<\/a>.<\/p>\n

\"\"<\/a>

At the turn of the millennium, the Irisbus Civis, which also used optical lane guidance, failed to deliver the hoped-for breakthrough, but more reliable and less radical vehicles later made the BRT concept a success in Europe as well (Photo: Rossendalian2013\/flckr.com)<\/p><\/div>\n

BRT systems offer benefits normally associated with rail-based mobility: a segregated alignment, priority at intersections, high-capacity vehicles, higher average speeds, accessible and often covered stations, and fast passenger exchange. They do all this more cheaply and flexibly, with faster implementation. Although BRT systems essentially originated in Latin America, where this mode has existed since the late 1970s, and are also popular in parts of Asia and Africa, the IRU\u2019s compilation focuses more on European examples \u2014 though at the end of the article we will also take a trip to Mexico. Below, through four practical examples, we show how this solution can replace metro or tram services, how it can help promote tourism, and also how major progress in passenger satisfaction can be achieved simply by organising accelerated bus routes intelligently, even on conventional infrastructure.<\/p>\n

A solution to a megacity\u2019s problems: \u0130ETT Metrob\u00fcs<\/strong><\/h3>\n

A good example of large-scale implementation is Europe\u2019s largest and best-known BRT network in the classic sense, Istanbul\u2019s Metrob\u00fcs system, which we also presented in detail on our portal<\/a> during our 2022 visit to the headquarters of operator \u0130ETT. Its special feature is that it is the world\u2019s only group of BRT services connecting continents, linking Europe and Asia across the Bosphorus.<\/p>\n

\"\"<\/a>

The network, which has been operating since September 2007, in fact physically consists of a single corridor following the route of Turkey\u2019s D.100 main road (two traffic lanes were taken away from cars for this purpose). Today, however, it is divided into eight routes and short workings, with extremely high frequencies \u2014 in places as short as 20 seconds \u2014 and a peak-period hourly passenger capacity of more than 30,000 people per direction. This clearly shows that, true to its name, the system here very much replaces a metro. Although the Turkish metropolis naturally also has an underground (and elevated) rail metro network, its expansion has been hampered by high costs, while BRT offered a fast and inexpensive way to address transport problems \u2014 the first, 18.5-kilometre Topkap\u0131\u2013Avc\u0131lar section was completed in just 77 days. In Istanbul, now home to almost 16 million people, heavy surface congestion is almost constant despite the multi-lane radial roads built across the city (something we have also experienced personally), which all but paralyses conventional bus transport on certain sections, especially in inner-city areas close to the strait. Thanks to its segregated infrastructure, the Metrob\u00fcs system therefore offers a meaningful fast-transport alternative to private modes (according to our local sources, unauthorised drivers who venture into the largely fenced-off bus lane are caught by police almost immediately), although the 1+1 lane layout makes it relatively sensitive to service disruptions.<\/p>\n

\"\"<\/a>

The picture speaks for itself: peak traffic in Istanbul before and after the construction of the Metrob\u00fcs corridor (Photo: \u0130ETT)<\/p><\/div>\n

The 52-kilometre BRT corridor, which operates continuously 24 hours a day, handles around one million journeys daily and is estimated to reduce passengers\u2019 time spent travelling by an average of 52 minutes per day. In addition to improving mobility, BRT also has well-measurable environmental effects: according to calculations, the system removes around 100,000 cars from traffic, resulting in a daily reduction in emissions equivalent to nearly 760 tonnes of carbon dioxide, even though only diesel buses operate on the route. The corridor, built in several stages, was delivered for just over USD 259 million, a fraction of the cost of a metro line of similar length. The fleet previously consisted of conventional articulated types (Mercedes-Benz Citaro G and Conecto G), followed by the Mercedes-Benz CapaCity and later the Otokar Kent XL four-axle extended articulated buses, but passengers can also ride on more unusual vehicles such as the Phileas and AKIA Ultra LF 25 bi-articulated buses. Despite the island-platform station layout, the system does not require special vehicles, which also helps reduce costs, with the compromise that traffic on the line runs on the left because the buses\u2019 passenger doors are on the right-hand side. For a long time, Istanbul had Turkey\u2019s only BRT system, but in July 2025 a second corridor opened in nearby Sakarya, also home to Otokar\u2019s factory.<\/p>\n

Aalborg: where the tram would have been too expensive<\/strong><\/h3>\n

A much smaller, but also noteworthy, European example is the case of Aalborg in Denmark, which clearly illustrates how BRT-type solutions can provide a cost-effective alternative to surface rail transit. We have also covered several times on our portal <\/a>the construction of the Plusbus corridor, Denmark\u2019s first BRT line, and the related vehicle procurements over recent years. The city of around 150,000 residents originally planned to build a tram line in 2011, but did not receive the necessary support from the Danish government for the project, whose total cost was estimated at EUR 240 million. The local authority therefore looked for an alternative solution and eventually found it in a BRT system built for EUR 70 million \u2014 less than a third of the cost. Here, the investment is part of a wider green transition project, under which a total of 121 electric buses and a new depot were commissioned, with Northern Europe\u2019s largest electric-bus charging infrastructure<\/a>.<\/p>\n

\"\"<\/a><\/p>\n

The 12-kilometre line has 22 stops, connecting the city centre, two important railway stations and the local university campus. In line with today\u2019s expectations, the route is served by fully electric, low-floor vehicles: the 24.7-metre, bi-articulated Solaris Urbino 24 electric MetroStyle buses<\/a>, which have a nominal capacity of 155 passengers, run every 7 to 7.5 minutes during weekday peaks and every 15 minutes outside peak hours and at weekends. Around two thirds of the route runs in segregated bus lanes, while priority traffic signals along the entire line and, in places, traffic restrictions help ensure smooth operation.<\/p>\n

\"\"<\/a><\/p>\n

Although scheduled operation began only in September 2023, making it a relatively young BRT line, the initial results are encouraging. According to reports, in the year following the introduction of the Plusbus system, passenger numbers in the area increased by 25%, and growth has continued since then, prompting the deployment of additional BRT vehicles. Meanwhile, the line has achieved a 95% self-financing ratio, meaning that ticket revenues cover the vast majority of operating costs. The journey time over the full line is 30 minutes, 5 to 6 minutes shorter than that of the former local bus route 2 that the BRT replaced. Passenger satisfaction on the service is outstanding, even compared with Aalborg\u2019s conventional bus routes, which also enjoy high approval \u2014 it is no coincidence that the Plusbus system won an urban development award<\/a> last year. The Aalborg example clearly shows that a well-designed BRT service that is attractive to passengers can be implemented at a favourable cost even in small and medium-sized cities, offering a high-quality alternative to rail transit.<\/p>\n

London\u2019s Superloop, or how to make the most of what you have<\/strong><\/h3>\n

The IRU summary also discusses the London Superloop network<\/a>, launched in July 2023, which is something of an odd one out here in several respects, as neither the vehicle design nor the infrastructure differs substantially from conventional bus operations. It is much more about branding and sensible route planning. In recent years, the local transport authority, Transport for London (TfL), has had to respond quickly to declining bus ridership and the need to serve suburban areas efficiently, but with limited infrastructure support. The idea of express services linking outer London areas in a loop was first raised in 2008 by then mayor Boris Johnson (to whom the English capital also owes the retro-futuristic New Routemaster double-deckers built by Wrightbus), but the final Superloop concept was not announced until 2023, under Sadiq Khan\u2019s mayoralty.<\/p>\n

\"\"<\/a>

The network currently consists of 12 routes, most of which together form a continuous orbital ring of around 218 kilometres (as the network\u2019s name suggests), connecting London\u2019s outer boroughs and their railway stations. An important feature of Superloop is that it builds on existing services: the vehicle operators are the same as on regular bus routes and there is no separate fare system, while dedicated infrastructure is essentially limited to the buses\u2019 partly white livery, illuminated Superloop emblems installed at the stops concerned, and the SL prefix before the route number. The most important difference is that these services stop only at key stops: a Superloop route has on average just 12 stops, compared with 68 on standard London routes.<\/p>\n

\"\"<\/a>

Superloop has now vindicated TfL\u2019s thinking: last year, these routes recorded a 10% increase in ridership, while the London network as a whole saw a roughly 5% decline over the same period. Passenger satisfaction is also around 10% higher than on conventional bus services, so it is not surprising that four additional Superloop routes are planned by 2027. London\u2019s experience shows that BRT principles can be applied even without major investment, with good branding and fewer but intelligently selected stops.<\/p>\n

BRT as the backbone of transport in Mexican metropolises<\/strong><\/h3>\n

Last but not least, let us also take a look at Mexico, where bus rapid transit systems are a national matter: today, BRT corridors of varying levels of development can be found in more than a dozen cities across the country, and in this part of the world they are a vital means of transport. Here we will focus in more detail on three cities with populations of over one million \u2014 Le\u00f3n, Mexico City and M\u00e9rida \u2014 but significant BRT networks also operate in places such as Puebla, Guadalajara and Ciudad Ju\u00e1rez. Electric buses have already begun to be introduced on some of the services presented below, so mobility development is contributing even more strongly to the achievement of decarbonisation goals.<\/p>\n

\"\"<\/a>

The Sistema Integrado de Transporte Optib\u00fas<\/i> in Le\u00f3n, or SIT Optib\u00fas for short, has been operating since September 2003 and was the Latin American country\u2019s first BRT system. At the time, its construction cost 1,405,700,000 Mexican pesos, equivalent to roughly EUR 114.7 million at the then mid-market exchange rate. Today, around 350,000 people travel daily on the network, which totals 65.1 kilometres and consists of 10 lines \u2014 its importance is underlined by the fact that around 85% of public transport in Le\u00f3n is handled by Optib\u00fas services. The system was built with the raised island-platform stations customary in Latin America, and the vehicles are configured accordingly: high-floor, typically chassis-based designs, with passenger doors on the left-hand side at platform level<\/a>. Locals refer to the articulated buses serving the system by the nickname La Oruga<\/i>, meaning \u201cthe caterpillar\u201d. Beyond the infrastructure, the advanced operational integration is also worth mentioning: on the hierarchical network, lower-capacity local feeder routes connect to high-capacity central trunk lines, reducing fragmentation and improving service reliability.<\/p>\n

Two years after Le\u00f3n, in 2005, Mexico City launched its similar service, Metrob\u00fas, which today, with seven routes, a combined route length of more than 174 kilometres and a daily capacity of one million passengers, ranks among the world\u2019s largest BRT networks<\/a> and plays a key role in public transport in the Mexican capital. Some routes use raised island-platform infrastructure, while others have conventional stops better suited to the historic city centre, making the fleet extremely heterogeneous: alongside classic Latin American standard-floor, bi-articulated BRT buses<\/a>, the network also features a wide range of types, from solo Volvo 7700s familiar from Europe and three-axle BYD eBus B15s<\/a> to double-deck Alexander Dennis Enviro500s. On some lines, electric buses have already taken over<\/a>, but the transition has not been smooth: under political pressure, efforts were made to carry it out at the lowest possible cost, which, according to the IRU, in some cases led to the procurement of types whose maintenance and parts supply pose serious problems.<\/p>\n

\"\"<\/a>

Mexico\u2019s youngest BRT system has been operating since December 2023 in M\u00e9rida, in the south-east of the country, and once fully completed it will be 116 kilometres long, with 70 stops, running largely in dedicated bus lanes with traffic-signal priority \u2014 all built for 2.82 billion pesos. The network, currently made up of six lines, creates fast, comfortable links as part of a wider economic and tourism strategy between the city\u2019s airport and tourist attractions, as well as two stations on the Tren Maya railway, which circles the Yucat\u00e1n Peninsula and is also primarily geared towards tourism, with interchange to local bus services. This is currently the only BRT system in Mexico where only electric buses operate across the entire network, and the operators chose an essentially European type, the solo version of the Irizar ie tram<\/a>. The focus on attractiveness is also reflected in the fact that, uniquely, it was essentially the design that sold the buses here: according to reports, Yucat\u00e1n governor Mauricio Vila Dosal was so taken with the model that this prompted work with the manufacturer on its introduction in Mexico, and later even the M\u00e9rida network itself (Ie-Tram Yucat\u00e1n) was named after Irizar\u2019s iconic vehicles.<\/p>\n

As the examples above show, BRT is not a single operating model that can be applied everywhere in the same way, but a cost-effective urban development concept that can be flexibly tailored to local needs. It can bring significant progress in passenger capacity, journey times, accessibility and emissions reduction, but for that to happen, buses must be treated as core transport infrastructure rather than as an additional, secondary solution. Recognising the benefits of BRT, similar systems have recently been appearing one after another in Europe as well: among recent developments, the Porto network, also named MetroBus<\/a>, is worth mentioning, while BRT projects are also under way in France<\/a> \u2014 regarded as the stronghold of enhanced-service bus routes (Bus \u00e0 Haut Niveau de Service<\/em>, or BHNS) \u2014 and in Italy<\/a>, even incorporating surrounding suburban settlements into urban transport. There are also more and more similar initiatives in the United States<\/a>.<\/p>\n
