How Do You Make Online Maps More Social, Ms Leal-Taixé?

Online services like Google Maps mean that nowadays everyone can find their way to Munich’s Octoberfest without any difficulty. But these online services still have their weaknesses. “If I want to get to the Wiesn, the digital map shows me the way,” says Laura Leal-Taixé, “but it doesn’t say, only leave in 20 minutes if you want to get through better.”

This is the kind of social information the computer scientist, who recently moved to Munich from Barcelona, wants to integrate into digital maps in her “Social Maps” project. So far, these services do not factor in how and when people interact in public spaces and the movement patterns that result – they neglect human traffic flows of pedestrians, cyclists or even schoolchildren. “What is usually a clear path can quite suddenly become completely blocked because a group of tourists crops up or lots of children all rush out of school onto the street at the same time where their parents are waiting in their cars to pick them up,” says Leal-Taixé.

She wants to capture and evaluate dynamic scenes like this in video sequences using special mathematical tools. These algorithms are not only able to analyse human traffic flows, they can even predict them. This could also be useful for town planners. When building a railway station, for example, it would make it easier to plan where and how many exits are required to channel commuters. Even if it does take a while before digital maps tell you the best time to head for the Octoberfest – the “new Municher” has already bought her dirndl.
