Equity Perspective

The multidimensional characteristics of the HSR networks make debated the benefits of them. In this context, the aim of this study is to review of Turkey’s HSR systems from spatial equity perspective within the framework of recent research and developments. The latest secondary data from the official statistics of the Ministries of Development; Environment and Urbanization; Industry and Technology of Turkey has been used for the purpose of the analysis. The research methods included: critical analysis of the source literature, analysis of secondary data (desk-research) and graphic methods (tables and maps), by means of which the results of the study have been presented. The main argument of study is that considering the current geographical location of the HSR network of the country, it creates challenges in terms of spatial equity and deepens the regional polarization. The existing HSR network has facilitated mobility, especially in terms of domestic tourism. However, the usage of the HSR by a limited part of population and restrictions applied due to the COVID-19 pandemic question the amount of returns of the HSR’s costs, which are enough expensive investments in Turkey. On the other hand, increasing inequalities arising from the HSR infrastructures shaped on the basis of factors such as the geographical features of the country, general development level, population and demand density, are tried to be minimized by roadway and airway alternatives.

The Impact

Efficiency impacts can be assessed based on improvements in accessibility promoted by the high-speed rail (HSR) project, focusing mainly on major urban areas. Spatial equity impacts originate from changes in the distribution of accessibility levels observed across such cities. This study uses the weighted average travel time and coefficient of variation to explore the impact of HSR on efficiency and spatial equity within the Central Plains Economic Region (CPER) and to build an “efficiency-equity” model to identify optimal upgrading of conventional rail (CR) lines to improve the accessibility of the CPER and mitigate regional disparities. The results indicate that since the operation of HSR, accessibility levels across the CPER have improved by roughly 24.56%, and the spatial distribution of gains has been uneven since the most significant improvements have occurred in HSR cities and large cities. Inequality in regional accessibility has increased by 28.12%, creating a more heterogeneous pattern of accessibility. With goals of “efficiency” and “equity”, an examination of the upgrading of CR as an approach shows that “Xinxiang-Jiaozuo” and “Xinxiang-Jiaozuo-Sanmenxia-Yuncheng” are the best upgraded lines for improving the efficiency of the CPER and limiting regional disparities. The results of this study serve as supportive information for the planning and construction of HSR lines and networks and for underdeveloped regional transport system policymaking.

The Impact

China’s high-speed rail was inaugurated in 2008; it has greatly improved accessibility, and reduced the time required to travel between cities, but at the same time, has caused an unfair distribution of accessibility levels. Therefore, this paper analyzes urban traffic roads and socio-economic statistics, using network analysis methods, accessibility coefficients of variation, and social demand indexes to explore the spatial and temporal characteristics of transport accessibility and spatial equity in China. By 2015, the national transport accessibility level will form a new pattern of “corridors” and “islands”, centered on high-speed rail lines and sites. Additionally, the opening of high-speed railways has improved, to a certain extent, the inter-regional accessibility balance, and increased accessibility from high-speed railway sites to non-site cities. Spatial equality was also analyzed using the accessibility coefficient and social demand index. In conclusion, studying accessibility and spatial equity plays an important role in the rational planning of urban land resources and transportation.
