UBike System Improvement / Bike sharing system

The purpose of "YouBike" is to encourage citizens to use low-pollution and low-energy-consumption bike sharing by deploying the short-distance transit vehicles. However, the system now transports bicycles between full and empty rental stations by truck, which leads to a result cross to the purpose: increasing air pollution. The concept of the new system stimulates citizens to have higher preference to use the Ubike for reverse commuting, so as to replace the need for trucks. Reduction of price calculated by this system creates a favorable loop to actual environmentally friendly life.
