LRV is a new urban traffic method suitable for mid-scale transportation between subways and buses. The high-tech LRV is an environmentally friendly transportation method, as it does not cause smoke or noise pollution. LRV is easy to drive on a sharp curved railway applied with an articulation system, and the completely unmanned operation system lowers the operation costs. As LRV reduces maintenance expense and power consumption, the initial investment and operation costs are both reduced.
