The introduction of High-Speed Railways (HSRs) redefines the connections between main territorial hubs, by reducing the travel times and guaranteeing better accessibility. Such infrastructures bring advantages in terms of travel performances, but have also some drawbacks especially for those, generally, mid-size cities that are downgraded. This paper introduces the Spatial and Social Equity Railway Indexes (SpREi and SoREI) to assess the variation in travel times, number of connections, prices and population affected by these changes. Such indexes are then applied in the north-western part of Italy (between the regions of Piedmont and Liguria) to analyse the performances of Alessandria and Asti, two cities that were part of the previous main line Turin-Rome, but have been downgraded to a secondary line after the opening of the new HSR. Their SpREI and SoREI reveal that, despite a slight reduction of travel times, the number of direct connections has decreased with a significant increase in ticket prices. Such performances are then compared to Turin and Genoa, the two main territorial hubs, revealing contradictory results: on the one hand, Turin has registered a performance boost in terms of accessibility and variations in ticket prices. On the other hand, Genoa has seen a low increase in fares and in the number of available connections, whereas average travel times have even increased, thus confirming that the introduction of HSRs may generate inequalities in the territorial connections and hence possible need of compensation by policy makers.

意大利北部高速铁路线的空间和社会公平意义

高速铁路(HSR)的引入重新定义了主要领土枢纽之间的连接,从而减少了旅行时间并保证了更好的可达性。这样的基础设施在旅行性能方面带来优势,但也有一些缺点,尤其是对于那些通常被降级的中型城市。本文介绍了空间和社会公平铁路指数(SpREi和SoREI),以评估受这些变化影响的出行时间,连接数量,价格和人口的变化。然后,将这些指数应用于意大利西北部(在皮埃蒙特和利古里亚地区之间),以分析亚历山德里亚和阿斯蒂的表现,这两个城市以前是都灵-罗马的主要线路,但已经降级为新高铁开通后的第二条线路。他们的SpREI和SoREI表明,尽管旅行时间略有减少,但直达航班的数量却随着票房价格的大幅上涨而减少。然后将此类表演与两个主要的地区枢纽都灵和热那亚进行比较,揭示了相互矛盾的结果:一方面,都灵在可访问性和票价变化方面表现出了提升。另一方面,热那亚的票价和可用连接数的增长很少,而平均旅行时间甚至增加了,因此证实了高铁的引入可能会在领土连接中产生不平等现象,因此可能需要赔偿政策制定者。随着机票价格的大幅上涨,直接联系的数量减少了。然后将此类表演与两个主要的地区枢纽都灵和热那亚进行比较,揭示了相互矛盾的结果:一方面,都灵在可访问性和票价变化方面表现出了提升。另一方面,热那亚的票价和可用连接数的增长很少,而平均旅行时间甚至增加了,因此证实了高铁的引入可能会在领土连接中产生不平等现象,因此可能需要赔偿政策制定者。随着机票价格的大幅上涨,直接联系的数量减少了。然后将此类表演与两个主要的地区枢纽都灵和热那亚进行比较,揭示了相互矛盾的结果:一方面,都灵在可访问性和票价变化方面表现出了提升。另一方面,热那亚的票价和可用连接数的增长很少,而平均旅行时间甚至增加了,因此证实了高铁的引入可能会在领土连接中产生不平等现象,因此可能需要赔偿政策制定者。都灵在交通便利性和票价变化方面均取得了显著成绩。另一方面,热那亚的票价和可用连接数量的增加很少,而平均旅行时间甚至增加了,因此证实了高铁的引入可能会在领土连接中产生不平等现象,因此可能需要赔偿政策制定者。都灵在交通便利性和票价变化方面均取得了显著成绩。另一方面,热那亚的票价和可用连接数的增长很少,而平均旅行时间甚至增加了,因此证实了高铁的引入可能会在领土连接中产生不平等现象,因此可能需要赔偿政策制定者。
