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

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
