Bus rapid transit systems and beyond: Exploring the limits of a popular and rapidly growing urban transport system

Master Thesis - MSc in Spatial Development and Infrastructure Systems

July 2011

Image from the publication

In the last decade, the world has seen a massive growth in the number of bus rapid transit systems (BRT). This growth was sparked off by the successful implementation of the first BRT system in Curitiba (Brazil) in the 1970s. BRT aims at providing cost-effective urban transport at a high quality of service, and it doubtlessly is a step ahead in the quest for affordable and improved urban public transport. However, rail-based systems are still a valid alternative for situations in which the limits of BRT systems are reached. Therefore, a main objective of this master thesis is to explore the limitations of BRT systems in urban areas. For this purpose, this work analyses the performance of different BRT systems regarding quality of service, capacity, and cost-efficiency. Threshold levels in passenger demand for choosing between modes are identified by means of a parametric cost model. Findings indicate that BRT has cost and quality advantages over conventional bus and light rail transit (LRT) operation at demand levels between ca. 250 and 2000 spaces per hour per direction. BRT proves to be especially favourable compared to LRT in situations where labour costs are low, where a high commercial speed can be achieved, where frequent services are desired, and where high vehicle load factors are tolerated. Empirical data show that in comparison to conventional bus systems, BRT offers particular quality advantages regarding capacity, accessibility, comfort, safety, and image.

Muenster, Germany: An example of promoting cycling in cities - Components of a high quality bicycle infrastructure. A short survey

Case studies in sustainable urban transport #2
March 2011

GIZ SUTP released its next document in the case study series. The document is titled "An Example of Promoting Cycling in Cities – Components of a High Quality Bicycle Infrastructure". This study introduces Muenster’s initiatives to promote cycling and outlines specifications and essentials of its bicycle infrastructure. It provides a case study and orientation for transport planners and policy makers who want to develop similar bicycle-based sustainable urban transport systems in their cities. The document is 22 pages long, full colour pictures.

White paper on transport

Roadmap to a single european transport area — Towards a competitive and Resource-efficient transport system
European Comission
March 2011

This illustrated brochure comprises the text of the european commission’s White Paper ‘roadmap to a single european transport area — towards a competitive and resource-efficient transport system’ (com (2011) 144 final of 28 march 2011) and a foreword by vice-president Siim Kallas, commissioner for transport. 

The European Commission adopted a roadmap of 40 concrete initiatives for the next decade to build a competitive transport system that will increase mobility, remove major barriers in key areas and fuel growth and employment. At the same time, the proposals will dramatically reduce Europe's dependence on imported oil and cut carbon emissions in transport by 60% by 2050 .

By 2050, key goals will include:
  • No more conventionally-fuelled cars in cities. 
  • 40% use of sustainable low carbon fuels in aviation; at least 40% cut in shipping emissions. 
  • A 50% shift of medium distance intercity passenger and freight journeys from road to rail and waterborne transport. 
  • All of which will contribute to a 60% cut in transport emissions by the middle of the century.

Estrategias para el desarrollo Portuario y Urbano de Buenos Aires

Ing. Jorge E. Abramian
Cámara Argentina de la Construcción
Octubre 2010

Desde hace algunos años existen opiniones encontradas sobre la capacidad del puerto para seguir respondiendo a la demanda de servicios y sobre la necesidad de relocalizar las actividades portuarias. Este informe brinda datos para permitir la evaluación de los conflictos generados en el uso de los espacios costeros y el tránsito, estima las necesidades futuras del comercio exterior, incluye consideraciones sobre la expansión del sistema portuario con la perspectiva del crecimiento de los movimientos de cargas en el Río de la Plata y analiza las posibilidades de compatibilización de usos en la franja costera. En suma, trata de responder a las siguientes preguntas: ¿Qué dimensión tienen los conflictos Puerto-Ciudad?¿es conveniente y/o posible la relocalización del Puerto Buenos Aires? ¿De qué manera y hasta qué punto se pueden compatibilizar las actividades portuarias con el desarrollo de la Ciudad?

World Bank gender transport surveys: An overview

Julie Babinard
Transport Notes Series
September 2011

Between 2008 and 2010 the transport sector initiated several country surveys to measure road transport needs and the constraints of both men and women, and more specifically how transport is facilitating or constraining access to resources, markets, and employment. These surveys were conducted as part of a lending operation or Economic Sector Work (ESW) with financial support from the Gender Action Plan (GAP), which seeks to advance women’s economic empowerment and accelerate the implementation of the Millennium Development Goal 3 (MDG3—promoting gender equality and women’s empowerment).

A report that reviews the methodology used for each country GAP-funded survey, the design and content of the questionnaires and the likely effect on the analysis shows that women tend to have access to a wider range of social and economic opportunities when transportation is available, safe and secure.
