Transport Systems And Policies For Sustainable Cities, Vukan R. Vuchic Jan 2008

Transport Systems And Policies For Sustainable Cities, Vukan R. Vuchic

Departmental Papers (ESE)

The 20(th) century witnessed revolutionary developments in transportation technology with major impacts on the form and character of cities. Progress in increasing mobility has brought many benefits as well as serious problems, particularly in deterioration of livability and sustainability. Increase in auto ownership led to serious problems of chronic traffic congestion. Attempts to rebuild cities to provide full accommodation of private cars have led to serious problems of auto dependency and deterioration of cities. Experiences from recent decades have shown that urban transportation is much more complex than usually realized. Livable and sustainable cities require policies that lead to ...

Light Rail And Brt: Competitive Or Complementary?, Vukan R. Vuchic Jan 2005

Light Rail And Brt: Competitive Or Complementary?, Vukan R. Vuchic

Departmental Papers (ESE)

Since the 1970s great progress has been made to develop transit systems which provide service considerably better than buses can offer in mixed traffic, but which require significantly lower investment than metro systems with exclusive ways. This “semirapid transit” category of modes, using mostly partially separated ways, has been introduced extensively in medium-sized cities, as well as supplementing metros in suburban areas of large cities.


Comparison Of Light Rail Transit With Bus Semirapid Transit, Vukan R. Vuchic Oct 2000

Comparison Of Light Rail Transit With Bus Semirapid Transit, Vukan R. Vuchic

Departmental Papers (ESE)

Selection of transit modes is one of the most important decisions in the transit planning process. A particularly important decision is the selection between bus and rail modes, because it influences the type of service that will be offered and, more importantly, the role transit will play in the city. Ultimately, such a decision has an impact on the quality of life in the city. It is therefore necessary to include in the selection process the physical and economic characteristics of modes, as well as the quality of service, attraction of passengers and the impacts of the transit system on ...

Achieving Intermodal Balance For Efficiency And Livability Of Cities, Vukan R. Vuchic Jan 1999

Achieving Intermodal Balance For Efficiency And Livability Of Cities, Vukan R. Vuchic

Departmental Papers (ESE)

At the closing of the second millennium our civilization can boast a remarkable progress in technological developments which have been growing at an exponential pace. Telecommunications, jumbo-jets and personal computers have become ubiquitous in many countries in recent decades. In the "softer" area of managing complex systems, and even more so in economic, social and ethical aspects, our achievements have not been as uniquely progressive, however. This dichotomy between technological advances and systemic difficulties is quite obvious in the focal areas of our civilization - the complex technical-social-environmental system of cities.

The heavily urbanized civilization entering the third millennium strongly depends ...


Increasing Potential Of Road Pricing For Improved Efficiency Of Urban Transportation, Vukan R. Vuchic, Antonio Musso Jan 1998

Increasing Potential Of Road Pricing For Improved Efficiency Of Urban Transportation, Vukan R. Vuchic, Antonio Musso

Departmental Papers (ESE)

There are a number of factors which contribute to the continuous pressure for driving in different cities. However most serious, but often overlooked is the problem that the structure of costs of driving stimulates excessive car use. This paper presents the structure of driving costs and classifies then into user, social and environmental costs. The incidence of all these costs is discussed. The importance of using road pricing for a more effective control of the demand for car travel is shown. The paper reviews objectives of road pricing and actions for their implementation and concludes that the need for road ...

Lrt - A Dynamic Transit Mode With Continuing Innovations, Vukan R. Vuchic Jan 1996

Lrt - A Dynamic Transit Mode With Continuing Innovations, Vukan R. Vuchic

Departmental Papers (ESE)

When increasing use of the private automobile intensified street traffic congestion, cities, generally pursued one or two types of policies. The "Car accommodation policy" was aimed 'primarily at accommodating the car and highway traffic, neglecting all other modes. The "Balanced transportation policy" was directed to achievement of a co-ordinated system of different transportation modes.

The former group of cities eliminated streetcars I tramways. The latter upgraded them through numerous innovations, into Light Rail Transit - LRT. The intermediate transit modes, which LRT represents, have been increasingly found effective as a solution for the cities which need better services than buses on ...

Short-Term Improvements For Septa's Regional Rail System, Vukan R. Vuchic, Shinya Kikuchi, Eric C. Bruun, Partha Chakroborty, Yong Shin Eun, Janaki Parameswaran, Nikola Krstanoski, Natasa Vukadinovic Aug 1994

Short-Term Improvements For Septa's Regional Rail System, Vukan R. Vuchic, Shinya Kikuchi, Eric C. Bruun, Partha Chakroborty, Yong Shin Eun, Janaki Parameswaran, Nikola Krstanoski, Natasa Vukadinovic

Departmental Papers (ESE)

SEPTA has made significant improvements on its Regional Rail System since its takeover from Conrail some 10 years ago. This system now offers highly reliable service; stations are clean, many have obtained improved platforms, signs and other equipment; Trailpasses are used extensively. Yet, the ridership is low relative to the excellent coverage the network provides, and it has had a predominantly declining trend. Moreover, financial results are unsatisfactory: the Regional Rail Division's operating ratio is considerably lower than the other SEPTA divisions' ratios. There is a serious danger that the system will continue along a "spiral" of increasing fares ...


The Bus Transit System: Its Underutilized Potential, Vukan R. Vuchic, Eric Christian Bruun, Nikola B Krstanoski, Yong Eun Shin, Shinya Kikuchi, Partha Chakroborty, Vijay Perincherry May 1994

The Bus Transit System: Its Underutilized Potential, Vukan R. Vuchic, Eric Christian Bruun, Nikola B Krstanoski, Yong Eun Shin, Shinya Kikuchi, Partha Chakroborty, Vijay Perincherry

Departmental Papers (ESE)

The bus system represents the most widely used transit mode. Upgraded bus services, primarily those which have partially or fully separated rights-of-way, represent a very cost effective method to improve the balance between automobile and transit. Many measures for improving bus services were introduced since 1970. However, many of these improvements were not maintained: buses were gradually returned to operations in mixed traffic. The report examines the quality of bus services in various cities in North America and worldwide and analyzes the reasons for the phenomenon of “backsliding” or disappearance of bus transit priority measures.


Role And Organization Of Transfers In Transit Networks, Vukan R. Vuchic, Antonio Musso Jan 1992

Role And Organization Of Transfers In Transit Networks, Vukan R. Vuchic, Antonio Musso

Departmental Papers (ESE)

Passenger transfers among transit lines involve certain "resistance", because they cause some delay and require passenger orientation and walking between vehicles on different lines. Therefore it is sometimes believed that transfers are undesirable and that they should be avoided whenever possible.

The fact is, however, that transit networks with many transfer opportunities offer passengers much greater selection of travel paths than networks with disconnected lines which involve no transferring. In addition, the more transferring is performed, the greater is network efficiency, because each line can be designed optimally for its physical conditions, volume and character of demand. Consequently, when transfers ...


Regional Rail Developments In North America, Vukan R. Vuchic Jan 1992

Regional Rail Developments In North America, Vukan R. Vuchic

Departmental Papers (ESE)

The increasing importance of regional rail systems for growing cities and metropolitan areas has been shown more clearly in North America than anywhere else in the world. In spite of extremely auto-oriented developments and policies which do not favor railways, a number of North American cities have extended and improved their regional rail systems in recent decades.


Theory And Practice Of Metro Network Design, Vukan R. Vuchic, Antonio Musso Jan 1991

Theory And Practice Of Metro Network Design, Vukan R. Vuchic, Antonio Musso

Departmental Papers (ESE)

Most transit networks are designed empirically. For bus net­works this process 1s often satisfactory because bus routes and networks are very dependent on local conditions, and they can be easily modified, allowing easy corrections of problems which line design may cause in operations. However, with transit systems which have extensive infrastructure, most typically metro lines and networks, corrections are ex­tremely difficult to make. Develop­ment of an optimal network and avoidance of design features which result in operational pro­blems are therefore of great im­portance. Yet, the experiences from the design and operation of such large older ...

Metro Systems In Year 200: Modernization, Diversification, And Expansion, Vukan R. Vuchic Jan 1986

Metro Systems In Year 200: Modernization, Diversification, And Expansion, Vukan R. Vuchic

Departmental Papers (ESE)

Mr. Vukan R. Vuchic deals with the latest developments of metro networks and with their future state in the 21st century.

He recalls the basic characteris­tics of metro and the positive and stimulating role it can play in large cities. While its first networks were opened more than a century ago, metro still knows an impor­tant growth: for example, it is the best adapted means of transport in some large cities in developing countries. Furthermore, technical improvements and a diversifi­cation of existing systems allow an ideal adaptation to the particu­lar conditions of each city.

At the ...

Designers Widen The Urban Rail Options, Vukan R. Vuchic

Departmental Papers (ESE)

Far from being rendered obsolete by car and bus, or squeezed out by rising costs, the pace, of metro construction has accelerated dramatically through three decades-· and this trend is con­tinuing. Once categorised by planners as suitable only for the most densely travelled corridors, urban rail is now appreciated as offering a continuous spectrum of choice from fully segre­gated metro and regional rail systems through to the streetcar or tram. Provided large and medium-sized citied have sound transport policies, there will usually be an important role for rail transit.


Timed Transfer System Planning, Design And Operation, Vukan R. Vuchic, Richard Clarke, Angel Molinero Oct 1981

Timed Transfer System Planning, Design And Operation, Vukan R. Vuchic, Richard Clarke, Angel Molinero

Departmental Papers (ESE)

This study analyzes various methods of providing transit services in low-density areas. These areas can be classified into two major categories. First, suburban areas of medium and large cities; and second, entire medium and small cities which have low population densities. One of these types of areas is found in most cities.

The focus of this study is the type of transit network and operation in which special transit centers are organized at which vehicles from several different lines converge at the same time, enabling passengers to transfer between any two lines, and then depart in their respective directions. This ...

Skip-Stop Operation: High Speed With Good Area Coverage, Vukan R. Vuchic Jan 1976

Skip-Stop Operation: High Speed With Good Area Coverage, Vukan R. Vuchic

Departmental Papers (ESE)

Increase of transit speeds is one of the most effective ways of increasing the attractiveness of transit for urban travel. While surface transit in particu­lar suffers from low speed, the desirability of higher speeds is not limited to it. Rapid transit has adequate speed for short to medium-distance trips in urban areas. However, for longer. trips, particularly when there is a competing freeway facility, the requirement for speed is rather high. Since many station spacings are adopted on the basis of area coverage, high operating speed of the trains often cannot be achieved. Thus, typical lines of urban rapid ...


Light Rail Transit Systems: A Definition And Evaluation, Vukan R. Vuchic Oct 1972

Light Rail Transit Systems: A Definition And Evaluation, Vukan R. Vuchic

Departmental Papers (ESE)

Rail transit represents a family of modes ranging from light rail to regional rapid transit systems and it can be utilized in a number of different cities and types of applications.

Many European cities of medium size employ very successfully light rail mode for gradual upgrading of transit service into partially or fully separated high speed, reliable transit systems. Analysis of these cities show that with population densities and auto ownership very similar to those in the United States cities, their transit systems offer a superior service and have much better usage than our cities.

Many modern features of light ...


Transit Federation -- A Solution For Service Integration, Wolfgang S. Homburger, Vukan R. Vuchic Jan 1972

Transit Federation -- A Solution For Service Integration, Wolfgang S. Homburger, Vukan R. Vuchic

Departmental Papers (ESE)

Inadequate organization of public transport services in urban areas, particularly in the large ones, is one of the major reasons for the unsatisfactory level of service and economic problems of the operating companies. Despite the current trend toward mergers of transit operators into large public agencies, the services in most cities remain fragmented in various degrees; integration is often not in sight due to organizational problems which appear insurmountable. Losses to the users, the operators, and the city from this situation are often very significant.

This article briefly analyzes the reasons for this situation, explores its consequences and their impor ...
