Why is a light rail system necessary in the Taipei metropolitan area? (Planning)
To turn Taipei into a world-class city, it is necessary to build an optimized MRT system, which includes not only heavy rail rapid transit on the major transit routes but also a light rail system. The function of a light rail system is to connect less busy areas with heavy rail transit routes. Cost of construction should also be considered: Since it is much cheaper to build a light rail system, it would be economically unsound to construct a heavy rail system along routes where there are fewer passengers.
In addition, the adoption of a light rail system will make it easier to extend mass transit into less densely populated areas. This will provide flexible and convenient service for residents and form a network complementary to the heavy rail system. Based on the reasons mentioned above, light rail will prove beneficial to Taipei and is in line with global trends.
