Distance Model

High-speed railway is recognized as a fast, safe, comfortable, low-power, and large volumes of new transportation mode. This paper proposes a dominate transport distance model with the consideration of origin-destination distance, travelling purpose, income, time value and transport preference. A numerical experiment indicates that km is the most attractive distance for the high-speed railway. In km, the air plane occupies most passenger market. The high-speed railway has no advantage when the distance is longer than 1600 km.

Research Findings

High-speed railway (HSR) is a new and increasingly popular transportation mode in China bringing about a significant impact on the economy, including tourism development. This article investigates the effect of HSR on tourism development in China based on a time-varying difference-in-differences model. Cities connected by HSR in 2013 and 2014 are regarded as the treatment group, while those without HSR services until 2017 are placed in the control group. The empirical analyses cover a large panel dataset comprising 163 cities in 2009–2017. The empirical results suggest that both domestic tourism revenue and tourist number are positively affected by HSR, and the effect is stronger for the undeveloped or geopolitically less important regions such as the inland or prefecture-level cities. Other relevant determinants of tourism include the availability of airports and the number of hotels in the cities. Our research findings have important policy implications for tourism development in China with respect to HSR.

The Impact

The high-speed railway (HSR) has affected accessibility at diverse spatial levels. Although previous studies have examined HSR impacts on accessibility and inequality, the price attribute in estimating accessibility is less noted. This study evaluates the effects of HSR on unequal accessibility at the South Korean national level, capital and non-capital regions and according to urban population sizes by comparing ticket prices to time values. There are two major conclusions of this study. First, an increase in time value through national growth or other exogenous conditions maximizes HSR impact and, thus, increases accessibility. For example, when the time value is 9.98 USD/h, the national HSR access inequality is reduced by 0.56%. However, when the time value is 6.02 USD/h, the reduction in the national inequality by the HSR is 0.19%. Second, if considering generalized travel time, HSR impact is maximized in medium cities rather than in large cities. When the time value is 6.02 USD/h (or 9.98 USD/h), the change in inequality between cities is −0.4% (−1.29%) in medium cities, while large cities show a −0.08% (−0.9%) reduction in access inequality.

Negative Sequence Current

Traditional electric trains have a low power factor, high loading variation change and inefficiency, generating both negative sequence current and the imaginary part of positive sequence current. Delta type Load Balancer associated with specially connected transformers is generally adopted to correct power factor and voltage imbalance. However, the modern trains used in High Speed Railway (HSR) have a power factor approximately close to unity, and therefore only need voltage imbalance correction. This study presents novel Load Balancer schemes, which are a modification of the Delta-type Load Balancer, with various connected transformers to correct imbalance. The symmetric component method is also adopted to determine the installation capacity of the proposed Load Balancer schemes.
