The programme of the “anniversary edition” of our regular GI colloquium already got published some weeks from now. However, we are pleased to announce an interesting additional talk that complements our panel. Dr Guibo Sun from the Chinese University of Hong Kong will talk about influences of the built-environment that correlate with aspects of pedestrians walking behaviour. Thereby, his talk will focus on a case study that has been conducted in the vicinity of metro stations in Beijing. Please find further information (e.g., abstract) at the corresponding descriptive page. The talk will take place at the 11th of June, at 04.15pm in the lecture hall at Berliner Straße 48.
