Yucca Mountain Ventilation Studies Support And Associated Code Enhancements, George Danko Mar 2002

Yucca Mountain Ventilation Studies Support And Associated Code Enhancements, George Danko

Publications (YM)

The Task 20 project was prematurely closed by DOE on the basis of becoming critical data to the Yucca Mountain project. Task 20 indeed delivered the first, published hydrothermal-ventilation model, MULTIFLUX V1.0 and V1.1 to BSC during 2001 to support the AMR Rev01 report. The numerical model is designed to predict temperature and humidity distributions in and around the emplacement drifts and on the waste packages stored in a ventilated, high-level nuclear waste repository.


Washington Metro: Planning For Growth, Vukan R. Vuchic, Jeffrey M. Casello Mar 2002

Washington Metro: Planning For Growth, Vukan R. Vuchic, Jeffrey M. Casello

Departmental Papers (ESE)

In 1966, the United States Congress created the Washington Metropoli­tan Area Transit Authority (WMATA) to take control of the District's priva­te bus system and develop a new Metro network for the Nation's capital. Following extensive planning, cons­truction of Washington's Metrorail transit system started in 1969. Seven years later, revenue service began on a 7-kilometre line section with five sta­tions in operation. Another 25 years later, in 2001, the originally planned Washington Metrorail system, shown in Figure 1, was completed, reaching a total of 166 kilometres with 83 sta­tions.


Städte Und Stadtverkehr Im 21. Jahrhundert, Vukan R. Vuchic Jan 2002

Städte Und Stadtverkehr Im 21. Jahrhundert, Vukan R. Vuchic

Departmental Papers (ESE)

Wenn man heute die komplexen Probleme des Verhaltnisses zwischen Verkehr und Stadten im soeben angebrochenen Jahrhun­dert voraussagen mochte, kann es nutzlich sein, das entsprechende Gedankengut aus dem letzten Jahrhundert und insbesondere aus den letzten Jahrzehnten zu analysieren. Es fall! dabei auf, dass viele Zusammenhan­ge zwischen der Verkehrs- und Stadtentwick­lung oftmals mit erheblicher Verzogerung verstanden wurden. Die ersten waren ver­standlicherweise die Fachleute und manche Politiker, welche auf diese Zusammenhange hingewiesen haben. Noch !anger dauerte es, bis sich die Einsicht in der Bevolkerung ge­nugend verbreitet hatte und es moglich war, praktische Maf3nahmen durchzufuhren.


An Evaluation Of Maglev Technology And Its Comparison With High Speed Rail, Vukan R. Vuchic, Jeffrey Michael Casello Jan 2002

An Evaluation Of Maglev Technology And Its Comparison With High Speed Rail, Vukan R. Vuchic, Jeffrey Michael Casello

Departmental Papers (ESE)

High speed rail (HSR) systems have a proven record of efficient services in about a dozen countries. Recently, Magnetic Levitation (Maglev) technology for high speed ground transportation (HSGT) has been proposed for many intercity and regional lines in Germany, Japan, United States, and other countries. Maglev developers claim that their system can achieve higher speeds, have lower energy consumption and life cycle costs, attract more passengers, and produce less noise and vibration than high speed rail. This article presents a systematic comparison of the proposed Maglev system, specifically the German Transrapid, and high speed rail systems.

The analysis reaches the ...


Bus Semirapid Transit Mode Development And Evaluation, Vukan R. Vuchic Jan 2002

Bus Semirapid Transit Mode Development And Evaluation, Vukan R. Vuchic

Departmental Papers (ESE)

With little investment required for operating in streets, bus services are often designed to serve many overlapping routes with frequent stops. To upgrade services and attract choice riders, major bus routes should be provided with exclusive lanes, preferential signals, and fewer but more distinct stops.

The Federal Transit Administration’s (FTA) Bus Rapid Transit (BRT) program is aimed at upgrading bus services into semirapid transit category (technically, bus semirapid transit). Many similar programs in the past were initially successful but later degraded by allowing sharing of lanes by high-occupancy vehicles (HOV) and relaxed enforcement of traffic control. With the systems ...
