Abstract
A gigantic evolution has been brought about in the railway transportation by the emergence of the expressways as the most efficient method of carrying passengers within short and medium interurban distances. Various types of expressway pavements have been offered during the recent years. A considerable amount of the repair and maintenance costs in railroad sector is allocated to the constituents forming the pavements. No thorough and precise research has been so far conducted on the railroad expressways featuring traffics with speeds over 250 km/h and the extant information have merely been trivial changes in the procedures existent for speeds below 200 km/h and these are not deemed of much use and applicability. Thus, the current research paper is devoted to the investigation and selection of express railways pavement system design using VIKOR method. The evaluations indicate that the commencement of the first high-speed train work in 1964 in Japan marked a turning point in the railroad passenger transportation in the world. The development of the high-speed railway transportation is enumerated as an important revolution helping the railroads retake their crucial role in passenger transportation in such a way that it is found overtaking the roadway and aerial transportation and even exposing some airlines to real crisis. The high-speed railroad is undergoing an intensive expansion worldwide and as a safe, sound and sustainable transportation system, it has well proved its role in the social and economic development of the nations.
Highlights
Railroad is the oldest and the first method of public transportation and it was unrivalled until the full-scale development of the roadway transportation in early 20th century in such areas as land transportation of cargos and passengers
After the WWII, the tremendous improvement in the production of the automobiles, autobahns and delivery of aerial services provided a greater many of the people with access to the other means of transportation by The passenger railroad has been less competitive in the US because the government has been, in the first place, concentrated on the aerial and roadway transportation and, secondly, in such countries as the US featuring a vast area and low population density the development of the passenger railroad and that of the high-speed type is not envisaged cost-effective [1]
According to the data and output of the VIKOR method, pavement systems of high-speed rail were categorized in terms of priority (Figure 2)
Summary
Railroad is the oldest and the first method of public transportation and it was unrivalled until the full-scale development of the roadway transportation in early 20th century in such areas as land transportation of cargos and passengers. The main goal of any industry related to transportation has always been to use the minimum available resources to enjoy the maximum benefits of the system and provide the most services to the users of that transportation system; , High speed rail technology is usually developed as a result of the advancement of conventional rail technology providing greater speed as well as safety for users of this network. It is a fast and efficient way to meet the demands of travelers who want a shorter trip with a higher quality [4]
