The Tel Aviv transportation system is seen as the hub of the Israeli transport network in terms of road, rail, and air transport. The Israeli road network partly centers on the city, with some of the country's largest highways passing through or running to the city. The city forms a major part of the country's rail network, whilst Ben Gurion International Airport located near the city is the country's largest airport. There is also a strong public transport system within the city, based primarily on bus transportation.
