context_page_description: Budapest is the capital and the most populous city of Hungary, and the ninth-largest city in the European Union by population within city limits. The city has an estimated population of 1,752,286 over a land area of about 525 square kilometres. Budapest is both a city and county, and forms the centre of the Budapest metropolitan area, which has an area of 7,626 square kilometres and a population of 3,303,786, comprising 33% of the population of Hungary.
  The history of Budapest began when an early Celtic settlement transformed into the Roman town of Aquincum, the capital of Lower Pannonia. The Hungarians arrived in the territory in the late 9th century, but the area was pillaged by the Mongols in 1241–42. Re-established Buda became one of the centres of Renaissance humanist culture by the 15th century.
  The Battle of Mohács, in 1526, was followed by nearly 150 years of Ottoman rule. After the reconquest of Buda in 1686, the region entered a new age of prosperity, with Pest-Buda becoming a global city after the unification of Buda, Óbuda, and Pest on 17 November 1873, with the name 'Budapest' given to the new capital.
context_section_description: Public transit in Budapest is provided by the Centre for Budapest Transport (BKK, Budapesti Közlekedési Központ), one of the largest transportation authorities in Europe. BKK operates 4 metro lines (including the historic Line 1, the oldest underground railway in continental Europe), 5 suburban railway lines, 33 tram lines, 15 trolleybus lines, 264 bus lines (including 40 night routes), 4 boat services, and BuBi, a smart bicycle sharing network. On an average weekday, BKK lines transports 3.9 million riders; in 2011, it handled a total of 1.4 billion passengers. In 2014, the 65% of the passenger traffic in Budapest was by public transport and 35% by car. The aim is 80%–20% by 2030 in accordance with the strategy of BKK.
  The development of complex intelligent transportation system in the city is advancing; the application of smart traffic lights is widespread, they are GPS and computer controlled and give priority to the GPS connected public transport vehicles automatically, as well as the traffic is measured and analyzed on the roads and car drivers informed about the expected travel time and traffic by intelligent displays (EasyWay project). Public transport users are immediately notified of any changes in public transport online, on smartphones and on PIDS displays, as well car drivers can keep track of changes in traffic and road management in real-time online and on smartphones through the BKK Info. As well all vehicles can be followed online and on smartphones in real-time throughout the city with the Futár PIDS system, while the continuous introducing of integrated e-ticket system will help the measurement of passenger numbers on each line and the intelligent control of service frequency.
  The development of Futár, the citywide real-time passenger information system and real-time route planner is finished already and now all of the public transport vehicle is connected via satellite system. The real-time information of trams, buses and trolleybuses are available for both the operators in the control room and for all the passengers in all stops on smartphone and on city street displays.
  The implementation of latest generation automated fare collection and e-ticket system with NFC compatibility and reusable contactless smart cards for making electronic payments in online and offline systems in Budapest is started in 2014, the project is implemented and operated by the operator of Hong Kong Octopus card jointly with one of the leading European companies of e-ticket and automated fare collection, Scheidt & Bachmann. The deployment of 300 new digital contactless ticket vending machine will be finished by the end of 2014 in harmonization with the e-ticket system.
  The tram lines no. 4 and 6 are the busiest city tram lines in the world, with one of the world's longest trams (54-metre long Siemens Combino) running at 2–3-minute intervals at peak time and 4–5 minutes off-peak. Day services are usually from 4 am until between 11 pm and 0:30 am. Hungarian State Railways operates an extensive network of commuter rail services, their importance in the suburban commuter passenger traffic is significant, but in travel within the city is limited.
  The organiser of public transport in Budapest is the municipal corporation Centre for Budapest Transport (Budapesti Közlekedési Központ – BKK), that is responsible for planning and organising network and services, planning and developing tariff concepts, attending to public service procurer duties, managing public service contracts, operating controlling and monitoring systems, setting and monitoring service level agreements related to public transport, attending to customer service duties, selling and monitoring tickets and passes, attending to integrated passenger information duties, unified Budapest-centric traffic control within public transport, attending to duties related to river navigation, plus the management of Budapest roads, operating taxi stations, unified control of bicycle traffic development in the capital, preparing parking strategy and developing an operational concept, pr
