The commitment acquired by the city council and the public transport company of San Sebastián has been to facilitate public transport as much as possible for all citizens of Donostia-San Sebastián.
Public transport service had been a request from associations of neighbours in the higher districts. The first line linked two high areas not only with the centre but also with important sites such as the Oncology Hospital and Matía Gerontological Foundation.
The Municipality of San Sebastián and the Public Transport Company designed the lines with a door-to-door service concept, meaning frequent bus stops. The operational cost per vehicle was around 250.000 € per year. A leaflet was sent to the residents of the districts concerned and since the beginning of the service it has met with great acceptance.
At the moment there are three minibus lines in operation, transporting over 800.000 passengers per year. The five vehicles running to provide the service have a capacity for 29 passengers and a wheelchair each. The vehicles have been adapted to ensure maximum accessibility.
Line 36 / San Roque-Aldakonea: Starting in 2005, this line is connecting two high districts, Aldakoenea and San Roque, with the centre zone. The served population is 3,000 inhabitants more or less, many of whom are elderly. The frequency is every 20 minutes from 7:30 until 22:30 on workdays. On Saturdays and public holidays, the service begins at 9:30. It has 1.600 users per day.
Line 37 / Rodil-Zorroaga: This line was started in 2006 with the objective to improve the public transport service of the zone of Rodil (there had only been a taxi-bus service) and to offer it also to the area of Zorroaga-Mendigain that previously lacked a PT service. The total population of these two served zones is approximately 4.000. Rodil-Zorroaga has an important city planning growth at the present time, so a PT service is essential for the present and future scene. The frequency is every 30 minutes, from 7:30 until 21:40, and at the moment it has 1.000 users per day.
Line 38 / Trintxerpe-Altza-Molinao: This microbus line links the zones of Larratxo and Altza with Trintxerpe and connects the population of Eskalantegi, Molinao and Darieta to fundamental services. In addition, it allows the densely populated high zones of Trintxerpe, Larratxo and Txingurri to enjoy a public transport service until now nonexistent, and has destinations at intermodal or important supply points like Gaiztarro or Herrera. The total served population amounts to approx. more than 4,000. The frequency is every 60 minutes from 7:30 until 22:00 and there are about 300 users per day.
The implementation of the new bus lines was strongly conditioned by the difficult access for conventional buses in the steep, narrow streets of the concerned districts.
