Ideally TFL would provide a realtime API of the number of Oyster card entrances and exits at each station. I work just off Oxford Street and at roughly 6pm every day travellers can't get into Oxford Circus station because of overcrowding at the platform level. If we could get a realtime overview of the number of people entering a station and see that the number of people entering is unexpectedly very low an app could direct people to enter at Bond Street / Green Park / Piccadilly Circus
