The assignment - Observe and identify a behaviour that can/should be changed 

People tend to stand around in the busiest part of the station

A perfect, unused part of the station

The idea - create a relaxing space for travelers waiting for their train. The space should be dimly lit, and have phone chargers for the travelers convenience. This makes it more attractive to sit and relax than stand in the way of busy travelers

The prototype - a space with LED-lit phonechargers, benches and dimmed lights that attract travelers with time on their hands
