The latter agency is responsible for the marketing and distribution of power generated at federally-financed installations.


New Transit Technologies: An Objective Analysis Is Overdue, Vukan R. Vuchic, Richard M. Stanger Oct 1974

New Transit Technologies: An Objective Analysis Is Overdue, Vukan R. Vuchic, Richard M. Stanger

Departmental Papers (ESE)

New urban transit systems incorporating inefficient and obsolete technical features are being promoted, discussed and funded. Typically they involve automatic operation with rubber tyre guidance; rail systems which are clearly superior are concurrently ignored. Dr. Vukan R. Vuchic of the University of Pennsylvania and Richard M. Stanger of the Metropolitan Atlanta Rapid Transit Authority* urge transit planners, operators and equipment manufacturers to exploit the great potential of rail technology rather than pursuing innovation for its own sake.

Rapid Transit Automation And The Last Crew Member, Vukan R. Vuchic Oct 1973

Rapid Transit Automation And The Last Crew Member, Vukan R. Vuchic

Departmental Papers (ESE)

Rapid transit systems in many cities are being automated, but most transit officials reject the idea of operation without crews on the train as idealistic. At the same time large resources are spent on development of full automation for numerous new systems such as PRT, many of which have no defined role in urban transportation programmed train movement eliminates any possible improper driving practices. However, nearly all rapid transit vehicles have indirect controls which prevent the driver from improper acceleration and assist him in braking. Thus improvement through A TO is again not significant.

Skip-Stop Operation As A Method For Transit Speed Increase, Vukan R. Vuchic Apr 1973

Skip-Stop Operation As A Method For Transit Speed Increase, 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 ...


A Study Of The Dickey-Lincoln Hydroelectric Project And Its Impact On The Resources Of The Upper Saint John River Valley, Rosemary M. Manning, Sierra Club, New England Chapter Jan 1973

A Study Of The Dickey-Lincoln Hydroelectric Project And Its Impact On The Resources Of The Upper Saint John River Valley, Rosemary M. Manning, Sierra Club, New England Chapter

Dickey-Lincoln School Lakes Project

This report was under-taken primarily to evaluate the impact that the construction of the Dickey-Lincoln project would have upon the resources of the Upper St. John River, and to examine the assertion that the Dickey-Lincoln project constitutes a wise use of the public's environmental and economic resources. Since the case that has been made for the construction of the Dickey-Lincoln project rest primarily on the justification of the project in economic terms, this aspect of the project proposal will be intensively explored.


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 ...


Value Of Speed In Public Transit Services, Vukan R. Vuchic, G Bruce Douglas Iii, Bondada V.A Murthy Nov 1970

Value Of Speed In Public Transit Services, Vukan R. Vuchic, G Bruce Douglas Iii, Bondada V.A Murthy

Departmental Papers (ESE)

High speed is always a desirable feature of public transportation services. Any measure that increases public transport speeds results in benefits to users in tenns of saved travel time, and benefits to the operator in reduced operating costs and in eventual reduction of fleet size.

At the same time, it is known that some major efforts for increasing speeds, often involving considerable cost (such as increasing maximum technical speed of vehicles) result in relatively small increases in average passenger travel speed. This problem is common for a number of different modes of transportation. An excellent example can be found in ...

A Critique Of The Delaware Valley Regional Planning Commission 1985 Regional Transportation Plan, David E. Boyce, Vukan R. Vuchic Oct 1969

A Critique Of The Delaware Valley Regional Planning Commission 1985 Regional Transportation Plan, David E. Boyce, Vukan R. Vuchic

Departmental Papers (ESE)

The 1985 Regional Transportation Plan of the Delaware Valley Regional Planning Commission (Plan Report No. 5) is one of the most detailed and informative reports published to date by a transportation planning agency. The Report reflects several advances in urban transportation planning procedures made by DVRPC. Nevertheless, the Report does contain a number of very serious deficiencies.

In an attempt to make a constructive contribution to transportation planning in the Delaware Valley Region, the authors of this Critique analyze these deficiencies and propose general and specific improvements for the Transportation Plan.

Propagation Of Schedule Disturbances In Line-Haul Passenger Transportation, Vukan R. Vuchic Jan 1969

Propagation Of Schedule Disturbances In Line-Haul Passenger Transportation, Vukan R. Vuchic

Departmental Papers (ESE)

Schedule disturbances in public transport operations have a tendency to intensify along the line and propagate to successive vehicles due to the uneven accumulation of passengers. This phenomenon, affecting efficiency and reliability of service, occurs frequently with surface services due to street con­gestion, as well as with rapid transit when It approaches capacity volumes. In recent years, considerable attention has been given to this problem.

Newell and Potts [1] (*), using a deterministic model, derived an expression for the behavior of delays both along the line and of subsequent vehicles at individual stations due to passenger accumulation. They gave a ...

The Role Of Public Transportation In Hamburg, Germany, Vukan R. Vuchic Jan 1964

The Role Of Public Transportation In Hamburg, Germany, Vukan R. Vuchic

Departmental Papers (ESE)

Hamburg is making serious efforts to solve the transporta­tion problem, common to most European cities-how to provide facilities to meet the rapidly increasing requirements of modem transportation and, at the same time, preserve the city's values by maintaining historic and other buildings, structures, and, particularly in the central area, its character. Being a large and relatively rich city with progressive ideas, Hamburg has accom­plished some remarkable achievements in this field. The purpose of this article is to delineate some of those achievements, particularly in public transportation.
