Malta International Airport is  from the city in the town of Luqa. Malta's public transport system, which uses buses, operates mostly on routes to or from Valletta, with their central terminus just outside the city gate. Traffic within the city itself is restricted, with some principal roads being completely pedestrian areas. In 2006, a park and ride system was implemented in order to increase the availability of parking spaces in the city. People can leave their vehicles in a nearby Floriana car park and transfer to a van for the rest of the trip.
