This document proposes a concept called Virtual Flow Track (VFT) to help manage crowds and ensure safety in dense, underground subway systems. As city populations grow, subways will become more crowded, increasing risks of accidents. VFT would use location data and displays to create a virtual guidance system that dynamically routes passengers in real-time based on crowd densities. When densities increase, VFT would appear and provide directions to less crowded areas. It describes how VFT could help in overcrowded, dangerous, and special needs situations like stairs by distributing passengers and creating safety zones with dynamic controls.

Context: Urban Cities
2015/04/20 “Trampling accident happened in Beijing subway. 20 people are injured.”
2015/06/11 “A man fractured his right leg bone in the subway in Beijing due to hustling in crowd .”
2015/06/11 “I'm Singaporean! Do you want to squeeze me out of Singapore?! ”
Total population of Singapore increase sharply from 4 000 000 people in2000 to
5 260 000 people in 2012.

After 15 years, city population will grow sharply.
The public transport especially subway will become the main
solution for most people. However, the question is how to
ensure the safety of the crowd in the closed space?
Recent Events

9. [ 3 Main Problems ]
Limited sight.
Limited facilities.
Comfortable space
-When you are lost in subway you feel
unsafe.
-It is hard to find your way in the
underground structure.
-Higher occurrence of accident due to high
human density.
-Shoving and pushing people
-People want to take a rest.
-People will take the corner seat, as they feel
more secure with their own personal space.
