A solid basis for the planning requirements of the future train station with regard to pedestrian flow

The train station Basel SBB PB constitutes an important hub for passenger transport nationally as well as internationally. Since its construction, the Basel train station has been extended several times. In the year 2003, the pedestrian underpass was replaced by an elevated walkway. The past years have shown, that the rising pedestrian flows have exceeded the capacity of the access points from the platforms to the elevated walkway (stairs and escalators). Bottlenecks were also occurring on the stairs between the elevated walkway and the station hall.
In the first phase of the study, ASE established traffic planning fundamentals. The focus hereby was on the additional access axes. It demonstrated to what extent an improvement would be achieved with an additional west or respectively east crossing. Furthermore, ASE evaluated, whether one crossing would be sufficient or a dual crossing needed to be built. ASE calculated the optimum position as well as the dimensioning for the proposed crossings.
During the following phases, various rough drafts were created based on the results from phase 1. A detailed concept for the facility was created and the findings were substantiated and recorded. The best option was defined and elaborated.
It followed, that a single additional crossing cannot prevent a congestion in front of the access points to the elevated walkway. At the same time, it showed that the situation could be substantially defused if two crossings were implemented. The optimum position for both of the crossings was located.
