Its aim is to interpret the subject of world culture in an interdisciplinary way. The museum is situated next to the Universeum science centre and the amusement park Liseberg, and close to Korsvagen. ""The museum interprets the concept of world culture in a dynamic and open-ended manner. On the one hand, various cultures are incorporating impulses from each other and becoming more alike. On the other hand, local, national, ethnic and gender differences are shaping much of that process. World culture is not only about communication, reciprocity, and interdependence, but the specificity, concretion and uniqueness of each and every individual.""

The purpose of the project is to increase capacity and reduce travel times on the Gothenburg network by changing the Gothenburg Central Station from a terminus to an underground transit station . Two new underground transit stations , Haga and Korsvagen , will also be built . Of the 920,000 people ( 2009 figure ) who live in Greater Gothenburg , 410,000 people live outside the Gothenburg urban area . Approximately 250,000 people in the region commute to or from Gothenburg Municipality . The majority of these people use cars for transportation and the roads in the region are overloaded . Better rail communications to different parts of Gothenburg and better connections to trams would improve the situation . There is a political wish to attract more public transport users . Significant sums of money have been -- and are being -- invested in rail infrastructure in the Stockholm region and the Malmo region , more than 20 bn SEK each during 1990 - 2010 , but much less in the Gothenburg region . The largest improvement according to the prosed plan would be for people who commute from places along the railways to Kungsbacka / Boras and who work or study near Haga station , where a large part of the University of Gothenburg is located . 15 minutes could be saved per journey . Time would be also saved on other journeys , for example around 5 minutes from Alingsas to Sahlgrenska or Chalmers . - Gothenburg Central Station is the main railway station of Gothenburg, Sweden.
