The introduction of high-speed rail dramatically shortens travel time between cities and markedly improves the main transportation network. This enhances the convenience of intercity travel, augments inherent demand for travel, and accelerates movement of people and business between cities.

The introduction of high-speed rail improves the network linking cities and communities along the railway. These become more attractive locales for living, business, industry, and tourism; and act as magnets drawing more people, companies, and information. This brings in additional investment, and serves as a catalyst for improved competitiveness and development of cities and regions along the railway as well as the country as a whole.

The introduction of high-speed rail greatly extends the radius of the one-day travel area. Single-day business trips, region-wide tourism, suburb-to-city commuting, and quick trips back home to see relatives all become the norm. High-speed rail makes it much easier for people to get around, which greatly alters their lifestyles, and creates more affluent living and communities.
