Where adequate density exists, HSR can be an important component of a sustainable transportation system and bring vitality to city centers. China has by far the most HSR lines-more than 50 percent of the total-with Japan and Western Europe not far behind. That is why only certain places in the world have sufficient population density to support HSR. HSR is expensive and requires high ridership to break even. Over time, its energy source is likely to get cleaner as renewables generate a greater share of electricity.

Compared with driving, flying, or riding conventional rail, it is the fastest way to travel between two points that are a few hundred miles apart and reduces carbon emissions up to 90 percent. That number will increase by 50 percent when current construction is completed many more thousands of kilometers are planned and under consideration. There were more than 56,000 kilometers of HSR lines worldwide in 2020. Growth is expected to continue as China and the European Union add to their extensive networks and new countries build their first lines. HSR has experienced significant growth in recent decades-especially in China, where the HSR network grew to almost 30,000 kilometers in a few years, representing around two-thirds of the global total. Careful pre-planning of the project and coordination amongst the stakeholders are necessary to accomplish a set of phased goals to realize the envisioned development of an HSR corridor.The International Union of Railways (UIC) defines high-speed rail (HSR) as a railway system where tracks are вЂњnew lines designed for speeds above 250 km/hr (155 miles per hour) and in some cases, upgraded existing lines for speeds up to 220km/hr (136 miles per hour).вЂќ

However, achieving the full development effects of an HSR project may take decades.

An HSR corridor is also beneficial to the cities along the railways, and the station areas provide an important opportunity to harness revenue through non-railway businesses. Last, an HSR corridor is beneficial both to the settlements along the corridor and to the railway operator. Such a synergy would enhance livability and provide improved quality of life opportunities in cities and regions served by HSR. A synergy between HSR and other elements, like urban transit facilities, paratransit, station area development, node, and sub-center development, can usher in spatial and economic development, but an institutional arrangement across all the elements is of paramount importance. We emphasize the importance of establishing a synergy between HSR and urban development. The HSR is expected to play a catalyzing role in driving the spatial and urban transformation process. Better accessibility will change the mobility patterns and will eventually affect the development in the impacted region, reshaping the entire urban-regional system. The HSR network changes the accessibility of a locality. There is ample evidence that at the regional level, the implementation of an HSR service disrupts the existing network of cities along the proposed corridor. We stratify and expand the understanding of the development effects of HSR at three levels - regional, urban, and station area вЂ“ based on the economic and temporal nature of all infrastructure projects. Positive impacts will be achieved only if interactions with other factors and contexts are maintained. HSR can simultaneously become a core component on desired urban developments, while also having undesirable outcomes. We summarize the evolution of HSR and elaborate on the development effects of the HSR transport infrastructure.

The potential effects of high-speed rail (HSR) reach into many overlapping fields of interest.
