Enormous growth of population has been observed in recent years and the number of passengers is traveling by the Indian railway has been increased significantly during the pilgrim season due to rapid urbanization. Pedestrian traffic is an important aspect of traffic handled by the Indian railways, because of competitive tariffs with other modes of transports, the comfort of travel, and speed of connectivity. The present study is carried out in the Kerala state railway stations under the categories of A1(NSG2), and A (NSG3) which has the highest annual passenger of boarding and alighting are recorded. Pedestrian flows are taken with the help of recorded video graphic footage on the railway station premises. The studies carried out in the pedestrian parameters and estimate the capacity of pedestrian flow involve a variety of pedestrians such as era, sexuality, belongings carried by the pedestrian, schedule of a train as well at entry and exit passageway of stairways with the help of Indo-HCM 2017 and NFPA 130, 2020 also to analyses the level of service of a pedestrian with the fundamental diagrams of the pedestrian flow vs speed, speed vs density, flow vs density, and space vs speed are developed. The discoveries of this study are expected to be fruitful for civic bodies, railway protection force, policymakers, the public, and other stakeholders to design a solution working on the idea of world elegance railway stations.

RESUMENLas infraestructuras de transporte presentes sobre el territorio condicionan las relaciones sociales y de comunicación de muchos espacios. Grandes estaciones, puertos o aeropuertos se presentan como ejes de centralidad sobre los que se distribuyen flujos de mercancías y personas, configurando a su vez el diseño y la funcionalidad de las ciudades. Hoy en día, con el avance producido en sectores como el ferrocarril de alta velocidad, las estaciones han transformado su función principal de nudo de intercambio, proyectándose como nuevos espacios comerciales y de negocio. En este artículo se analiza este nuevo fenómeno de transformación espacial y social vinculado a la alta velocidad ferroviaria, focalizando su ámbito en España. Se desgrana a su vez el papel de las comunidades sociales, políticas y empresariales para la ciudad y el espacio público presentes en las nuevas estaciones de ferroviarias. Palabras clave: ferrocarril; espacio público; urbanismo. ABSTRACTThis work aims to discuss the transport infrastructures presents on the territory and the conditions to the social and communication relations of many spaces. Large stations, ports or airports are presented as axes of centrality on which flows of goods and people are distributed, configuring in turn the design and functionality of cities. Nowadays, with the advance produced in sectors such as high-speed rail, the stations have transformed their main function as an exchange hub, projecting themselves as new commercial and business spaces. This article analyzes this new phenomenon of spatial and social transformation linked to high-speed rail, focusing its scope in Spain. At the same time, the role of the social, political and business communities for the city and the public space present in the new railway stations.Keywords: railroad; public space; urbanism.

The Impact

Abstract In all markets, firms go through a process of creative destruction: entry, random growth, and exit. In many of these markets there are also regulations that restrict entry, possibly distorting this process. We study the public interest rationale for entry taxes in a general equilibrium model with free entry and exit of firms in which firm dynamics are driven by reputation concerns. In our model firms can produce high-quality output by making a costly but efficient initial unobservable investment. If buyers never learn about this investment, an extreme “lemons problem” develops, no firm invests, and the market shuts down. Learning introduces reputation incentives such that a fraction of entrants do invest. We show that if the market operates with spot prices, entry taxes always enhance the role of reputation to induce investment, improving welfare despite the impact of these taxes on equilibrium prices and total production.

Hierarchy Process

Abstract This study proposes a hybrid multiple criteria decision making (MCDM) methodology for evaluating the performance of the Indian railway stations (IRS). Since the customers are heterogeneous and their requirements are often imprecise, the evaluation process is a critical step for prioritizing the IRS. To improve the existing approaches, an efficient evaluation technique has been proposed by integrating rough numbers, analytic hierarchy process (AHP) and multi-attribute border approximation area comparison (MABAC) methods in rough environment. The relative criteria weights based on their preferences given by experts is determined by rough AHP whereas evaluation of the alternatives based on these criteria are done by the modified rough MABAC method. A case study of prioritizing different railway stations in India is provided to demonstrate the efficiency and applicability of the proposed method. Among different criteria “proactively” is observed to be the most important criteria in our analysis, followed by ‘Railfanning’ and ‘DMO’ is found to be the best among the forty IRS in this study. Finally, a comparative analysis and validity testing of the proposed method are elaborated and the methodology provides a standard to select IRS on the basis of different criteria.

Simulation of complex scenarios and multi-direction pedestrian flow is a main challenge to microscopic model of pedestrian movement. It is an issue to simulate real pedestrian traffic with great fidelity while keeping its computational cost at an acceptable level. This paper reports on an improved floor field model called vector floor field model to simulate pedestrian flows in some basic scenarios. In this model, vectorization of static floor field and dynamic floor field are used to indicate preference directions and the pedestrian flow tendency, respectively. Pedestrian transition depends on both their preference directions and tendency. The simulations in some basic scenarios are conducted, quantitative comparison to the record of practical experiments and standard floor field model is given as well, and the results indicate the effectivity of this model. An adjusted static vector floor field is also proposed to simulate pedestrian flow in turning scenario. The vector floor field model is also sufficient to simulate some essential features in pedestrian dynamic, such as lane formation. This model can be widely used in the simulation of multi-direction pedestrian at turning, crossing and other junctions.

This chapter examines the public secrecy and popularity of spirit cults in Yan'an in the context of the urbanization of the rural area. It first provides an overview of folk popular religion and spirit possession in and out of China before discussing how deity worship figures as a form of unspoken yet widely circulated knowledge, communal bonds, and spiritual services in rural Yan'an. It then considers how spirit cults in Yan'an produce what it calls a “surrogate rural subjectivity” and proceeds by turning to the emergence of women spirit mediums in the 1990s. The chapter argues that, in the context of rapid urbanization, spirit cults provide occasions for the expression of disappearing rural communal relations, folk values, and ritual memories. It also suggests that folk religion now constitutes a new form of rural discourse through which the urbanizing rural subject of China is recognized. Finally, it describes spirit cults as a major site through which rural norms, values, dispositions, and desires are de facto produced and reconstructed in the urbanization of the rural area.

The City

The quality of urban space in terms of walkability can be assessed taking many parameters into account, such as the presence of sidewalks, their density and continuity, appropriate technical parameters as well as the presence of greenery, squares, parks, which create the environment for pedestrian traffic. The lack of travel barriers, the possibility to shorten the route, travel safety and security, the presence of street furniture, shops and services are also significant. This article concerns some of the above described factors and presents selected research results on the use of space in city centers of several Polish cities – Kraków, Gdańsk, Szczecin, Warsaw, Gdynia, Wrocław and Poznań as well as the results of an analysis on the friendliness of this space for pedestrian traffic. The first phase of this study was to determine the share of public space within the analyzed city center areas, and then define areas used as roads, infrastructure for pedestrians and cyclists, squares, green areas, parks and public courtyards. The balance of the used space was created for each researched area, and the space dedicated to pedestrian traffic was additionally analyzed in terms of the presence of obstacles as well as sidewalk location. The analysis results prove that that greatest amount of the public space is located in the city center of Poznań, and the smallest in Kraków. Warsaw is characterized by the greatest and Szczecin by the smallest percentage of the pedestrian infrastructure. Szczecin dominates in terms of the share of roads in the downtown area, Wrocław in terms of squares and Gdańsk – public courtyards.

The Paper Will Address The Crisis Of Railroad-Highway Grade Crossing Accidents In The United States. A Railroad-Highway Grade Crossing Is Where A Public Or Private Roadway Crosses Railroad Tracks. Over The Years, There Have Been Many Studies And Programs To Warn The General Public Of The Hazards Of Crossing Railroad Tracks. However, The Same Types Of Railroad-Highway Crossing Accidents Continue To Occur, Despite Attempts To Educate The Public. As Will Be Discussed, Communication Between Transportation Professionals And Coordination Of Railroad And Highway Operations Also Contributes To The Crisis. The Most Effective Way To Eliminate Grade Crossing Accidents Is To Provide Grade Separation Of The Railroad From Vehicle And Pedestrian Traffic. This Has Been Completed At 39,68 1 Locations. It Is A Very Expensive Proposition. Therefore, It Has Been Done Only In Urban Areas, And Along Limited Access Highways And Arterials. The Cost Of Constructing A Grade Separated Crossing Is Estimated To Be Five Million Dollars Per Location.
