Redesign Handle Subway. Me and my colleagues doing some research for handle subway and here are the key finding:

•Standing passengers are susceptible to suffering falls and other injuries.

•Shorter people may not be able to reach ceiling-mounted handles, straps, or rails.

•The pole always crowded by many people and hard to hold on

After we found the problem we try to make a new design for previous handle. This project was presented to the lecturer at Beijing Institute of Technology
