COMPARISON BETWEEN FEASIBIITY OF HIGH SPEED RAIL & ELECTROMAGNETIC RAIL IN BANGLADESH(PART-2)


DEFINITIONS
To facilitate the development of the thesis of this paper, definitions of the principal expressions are given below:

Information Age:
The current era in theory’s histry characterized by the rapid introduction of high-speed digital communication networks linked to computers for the near-instant global transmission of voice, text, data and imagery. A distinction of the Information Age is that the cost of knowledge labour is greater than the cost of fixed investments.

Knowledge-based Society:
An expression characterizing a post-industrial society having occupations primarily involved with generating products, processes or services which have a high knowledge content and hence are researched, developed, produced, deployed, used, serviced and enjoyed by a population having a high education level or specially labour skills. Those working in such sectors are called ‘Knowledge workers’ and live anywhere

Metropolis:
The Greek word, ‘Metropolis’ means ‘Mothers City’, connoting a powerful city that exerts an economic and protectorate influence over neighboring smaller cities, towns and villages. The word ‘polis’ means a city, an urban area where citizens can work, live, study, play, worship. Metropolises that evolved in the first half of the century owe their urban form mostly to public transit tramway, commuter rail and subway linking surrounding communities to the ‘Mothers City’; more conform to the automobile /road system.


Techno pole:
A geographic concentration of rivals, customers and supplies that promotes efficiencies and specialization via regular interchange and cooperation with industry research and development efforts. Metropolises are too confining an urban form to sustain growing agglomerations for the techno pole.

Megalopolis:
The term ‘Megalopolis’ defines an extended urban complex that comprises several large metropolises & their metropolitan areas (such as Boston-New York-Washington, Tokyo-Nagoya Osaka, Montreal-Ottawa-Toronto, or Paris-Brussels-London as examples).

Inter- Active Megalopolis:
The geographical  entity that made up  of a series of metropolitan complexes or ‘urban islands’ that are linked by telecommunications & transportation &  hence interact with each other. The importance of the adjective ‘Inter-Active is that in the information  Age, there is an expectation to be able to quickly and easily transfer electronically & physically within the Megalopolis .

MAGLEV:
An acronym for  a tracked mode of passenger transport that utilize either electromagnetic (attraction) or electrodynamics (repulsion) forms of levitation technology for the non-contact suspension, guidance & linear motor  propulsion on an elevated  guideway . High-speed versions can have operational speeds up to 500 Km/hr.

Transportation Demand Modeling:
The quantitative for estimating the ridership for new transportation services. Conventional or ‘extrapolative’ modeling methods project future ridership based on modal diversion using historical data; their variables are primarily trip time, fair,
frequency and modal performances. Most models ignore the spatial dimension in transportation planning by separating travel markets are be arbitrarily into inter-urban and inter-city. This separation overlooks the spatial changes in trip behavior thus underestimating ridership.

Induced Travel Demand:
The ridership generated or ‘induced’ as a result of the introduction of a new transportation service. This ridership is additional to that attracted from other modes of transport. The estimation basis is ‘normative’, that is, envisaging the economic and social activities plus behavior population twenty years hence and quantifying these needs to work backwards to estimate the demand (induced by the envisaged activities) and subsequent justification for sizing of the infrastructure and service level. Induced demand modeling accommodated the spatial dimension, that is , trip length, thus blurring in separation between inter-urban and intercity consideration. This tends to more effectively reflect the urbanization reality of the evolving Inter-Active Megalopolis, the widespread use of telecommunications and expanding separation of work and residence sites.  
 
 
OBJECTIVE

Intercity commerce and travel from DHAKA to COX’S BAZAR through CHITTAGONG is important to the region’s economic health. With increasing demand for regional travel causing airline delays and highway backups, the cost of travel in terms of both time & money has begun to raise concerns within the public & private sectors.
For this purpose, our destination is to establish a new rail track by estimating the costs.

This paper has five objectives-
First, to provide review of the existing transportation facilities in Bangladesh.

Second, to provide an analysis of High speed rail & Electromagnetic rail technology project in other areas of the world.

Third, to compare feasibility of High speed rail & electromagnetic rail of a new track from DHAKA to COX’S BAZAR through CHITTAGONG.

Forth, to estimate the cost of High speed rail & electromagnetic rail.

Last, to examine future developments in the area of rail transportation and identifying important issues.

SCOPE

This paper has two scopes-

First, to provide an analysis of the economic and developmental impacts of High speed rail & Electromagnetic rail network and its associated costs on this region’s transportation needs.

Second, To check the feasibility of  High speed rail & Electromagnetic rail in the route of  DHAKA to COX’S BAZAR through CHITTAGONG.


Several key issues are identified in the research. These points from the structure of this paper. They are:

·        Technical  Feasibility-
This feasibility includes availability of materials & technology used to build up the track in a particular country/region.
      
·        Economical Feasibility-
This is the feasibility of cost to provide materials & technology used to set up the track.

·        Demand Feasibility-
 Demand depends on saving of both time and money of people who use these trains specially for causing far away of airport from centre of the city, airline delays & highway backups.
