Transformable Seats• Why transform seats?
Solution 1
Crowdedness Measurement Criteria (for one part of subway)Degree of Crowded-ness
Measurement Criteria Boarding number
34% Seats are all taken. 5459% Seats are all taken and about 20 people
are standing.94
100% Seats are all taken and about 4 people are standing in front of each door.
160
150% Seats are all taken, about 8 people are standing in front of each door and 2 lines of people are standing in the middle.
240
200% Seats are all taken, about 10 people are standing in front of each door and 3 lines of people are standing in the middle.

Transformable Seats• Pushed toward the wall during rush hour.
• Anchored to the ground –at the bottom of each seat, for safety
Solution 1
Customized handles• A sensor on the ceiling automatically detects each person’s height
• Adjusted according to the height of the person under the bar
• No swinging hand straps
• All 3 bars can be utilized in rush hour
Solution2
Poles & Shorter handholds• 1 pole between doors – 4 poles per car
• For kids and shorter people who can’t reach to the upper bars
• Measure people’s body temperature and automatically adjust the
temperature in a subway car
Solution3
Subway stop indicator• The whole car banded with a line of screens
• The name of next stop moves around the car
• Increase visibility
Solution4
Vibrator in the seat• People enter the name of their destination to the vibrator
• Vibrates when the person has to get off
• Works as an alarm
• Can be connected with mobile phones via Bluetooth to give informa-tion on the stations
Solution5
Brighter lighting• Fluorescent light bars covered with translucent plastic
• Better distributes light throughout a car
• Protects your vision
Solution6
Power-generating floor• Stores the kinetic energy generated by crowds
• Used to power lightings, display systems, etc.
