The city Sabadell, located 23 kilometres in the northeast of Barcelona, grew during the strong industrialization, which took place particularly in the textile sector in the second half of the 19th century and turned into one of the most important cities of Catalonia. Nowadays, after this outstanding position was lost by the stagnation, the city tries to consolidate over the promotion of the tertiary sector as a new centre. In addition it has an important transportation network: two motorways, two railways companies, nine bus lines and a private helicopter airport.
The two railway lines, FGC (Catalan Government Railways) and RENFE (National Network of Spanish Railways), which carry independently numerous commuters between the centres of Sabadell and Barcelona, are not connected for the moment. An extension of 800m of the FGC line up to the RENFE Sabadell main station would provide this central location with the necessary complexity to build there a new Intermodal Transport Station that would significantly increase the efficiency of the existing infrastructure.
The location of the RENFE Sabadell Central Station is a 2ha large open space, which is partially used by the existing bus station. It is a fragmented passage area, in which the priorities of vehicle traffic are posed perceptibly before those of the pedestrian. The lack of space quality, caused by physical and visual discontinuities, makes the use of the existing square uncomfortable and the stay little attractive and stands in contrast to the increasing value of the quarter, in which industrial buildings are replaced by houses and where the rising number of inhabitants claims for a quality public space in the surrounding.
In this project the bus station is located underground in order to use the roof of the station, formed by inclined surfaces that form a continuous barrier-free promenade with slopes of less than 6%, as public space. Punctually these surfaces rise up to allow access and the interior of the station to be illuminated naturally. Under the square level a comprehensive station hall organised in five levels connects the different means of transportation: Interurban buses, trains and parking for travellers and residents.
Approach and parking for cars and taxis are organized in function of the holding times. As a result, the parking for W&R (wait and ride) and K&R (Kiss and ride), whose holding times in most cases do not exceed 10 minutes is organised along the main and secondary accesses, while the parking for the P&R (Park and Ride) consists in an two-story underground garage for 120 cars occupying the space between the street level and the FGC station. The walkways between parking to the station are below 300 m in length, because greater distances provoke illegal parking in double row or in pedestrian areas. The motorcycle and bicycle parking are located at a distance of less than 50m to the main entrance.
The new Intermodal Transport terminal, as extension of the public space, facilitates transfer between the different means of transportation, shortens the walkways and the duration of the trip and therefore makes the use of public transport more attractive and more comfortable.
