A BRT Corridor Through Stockholm’s Inner-city : Assessing the Operational Impacts of a BRT Corridor Along Bus Line 4 Using Microscopic Simulation

CARON MALUCELLI, FRANCISCO January 2020 (has links)
Bus Rapid Transit (BRT) corridors and systems have emerged in the past three decades as affordablesolutions of medium capacity public transport services to highly urbanized areas, especially in LatinAmerica and Asia. In Stockholm, trunk bus lines have gained priority over mixed traffic over the yearsthrough exclusive bus lanes, signal priority, and reliability control, for example, but no complete BRTsolution has been implemented yet. Among the inner-city trunk lines, Line 4 is the most demanded witharound 70,000 passengers boarding the service daily. This thesis proposes, then, to assess theoperational impacts that BRT solutions as segregate median lanes, stations with off-board farecollection and platform level boarding and alighting through all bus doors, full signal priority andheadway control strategy, would have in bus Line 4, using a microscopic simulation approach. Twoscenarios were simulated, and the results compared to the existing conditions (Base Scenario).Scenario 1 considered a 5-minute headway service and Scenario 2, 3-minute headways. Overall, theproposed scenarios reduce travel times by 37.6-49.1%, increase average operational speeds (includingdwell times) by 60.4-96.6%, decrease dwell times by 57.9-65.6%, decrease delays by 18.4-36%,decrease vehicle occupancy rates by 3.5-44.9% and improve the Coefficient of Variation of theheadways from 0.83-0.85 in the Base Scenario to 0.1 in Scenario 1 and 0.2 in Scenario 2. As a resultof the reduction in travel times, a BRT service would need 13 buses to operate a 5-minute headwayand 21 buses for a 3-minute headway, against 27 vehicles that are used currently for a 4 to 6-minuteheadway during peak hour.

Determination of the most appropriate bus rapid transit system for the eThekwini Municipal Area

Adewumi, Emmanuel Olusegun January 2014 (has links)
Submitted in fulfillment for the degree of Magister Technologiae: Civil Engineering: Civil Engineering and Surveying, Durban University of Technology. Durban. South Africa, 2015. / Invariably, a high percentage of the population of South Africa depends on public transport. In order to continue to satisfy commuters in terms of comfort, travel time, reliability of service and traffic congestion, there is a need to improve the efficiency of moving passengers to reduce travel time, delay time and number of stops. In the quest for advancement and improvement in public transport, many countries now embark on Bus Rapid Transit (BRT) systems based on the successful implementation of the system by cities like Curitiba (Brazil) and Bogota (Columbia). Government departments/transport authorities are often faced with the challenge of selecting the most suitable BRT system relative to the unique features of its transport demands and urban layout. Hence, this study proposes the determination of the most appropriate BRT system for the eThekwini Municipal Area (EMA). An in-depth literature review was conducted in order to determine the most adoptable BRT system amongst median, kerb side and segregated BRT systems, taking into consideration cost implications, safety of the passengers, pedestrian crossing, physically challenged commuters, vehicle option and manoeuvres. Physical assessment and critical review of the current operating BRT systems in Johannesburg, Cape Town and Port Elizabeth in South Africa was employed in this study as well as a critical comparison among these systems. The pros and cons of the three functional BRT systems in South Africa were stated and a way forward for EMA was recommended. Lastly, an assessment of the proposed BRT system in EMA was conducted on the existing Phase 1 and the remaining three phases. The review conducted was based on route inspection, access to property, factors considered in the selection of a BRT system, demand analyses of the routes and the evaluation of Johannesburg, Cape Town and Port Elizabeth BRT systems. Guidelines were also provided for the remaining proposed BRT routes which could be adopted by the eThekwini Transport Authority (ETA) in order to enhance a better performance in EMA over the three functional BRT systems in South Africa using the aforementioned criteria.

An Assessment Of The Planning And Operational Performance Of The Bus Rapid Transit In Istanbul

Yuce, Elif Can 01 March 2013 (has links) (PDF)
In Turkey, the only city that currently operates BRT is Istanbul. There are researches that focus on different BRT systems in the world, yet there has not been a comprehensive, systematic and comparative evaluation of the BRT experience in Istanbul. There seems to be an urgent need to study this BRT investment, with a particular focus on planning, operation and ridership characteristics with a comparative approach. This thesis analyses the BRT corridor in Istanbul and answers the question whether Metrob&uuml / s in Istanbul is a success or not. In order to understand the criteria for defining success, planning, operation and ridership characteristics are identified based on the previous literature and particularly the analysis of three best practice cases that currently operate BRT / these are Curitiba, Bogota and Mexico City. The study sets the criteria in planning, operation and ridership of BRT systems drawn by previous studies and answers by people who were involved in these projects. It compares the best practice cases and the Istanbul Metrob&uuml / s / focusing on planning and operation characteristics and using primary indicators of performance and ridership. The study reveals strength and weaknesses of the Istanbul Metrob&uuml / s in comparison to best practice BRT cases in the world. The findings provide lessons both for the future extensions of the BRT in Istanbul and for other cities that may consider implementing this transit technology.

Alleviating traffic congestion in Montreal's Champlain Bridge corridor : commuter rail or express bus?

Armstrong, Derek January 2005 (has links)
Car dependency has resulted in traffic congestion in the Champlain Bridge corridor between the South Shore and Montreal CBD. This thesis addresses the ongoing debate of whether an inflexible rail or more flexible express bus system is better suited for travel in the corridor. An exploratory analysis of commuters revealed dispersed work destinations, suburb-to-suburb commuting, and public transit constraints for car users, providing evidence that rail would not be an effective solution. Factors known to affect mode choice such as access walking time, cost, and number of transfers were quantified in a discrete choice model of mode choice by commuters in existing rail corridors in Montreal. The model was then applied to the Champlain Bridge corridor under the assumption of hypothetical rail implementation. The projected demand for rail was lower than current express bus use in the corridor, suggesting that there would be no justification in incurring the great expense of building a rail system to replace the current express bus system. Improvement of the established bus system would have greater potential to reduce car trips.

The social and economic effects of the Rea Vaya Bus Rapid Transit System (BRT) in the Gauteng Province

Rahim, Haseena 01 1900 (has links)
This study aimed at examining the social and economic effects of the Rea Vaya Bus Rapid Transit system (BRT) on various stakeholders in Johannesburg. The objective of the study was to investigate the effect the Rea Vaya has had on users and non-users of the Rea Vaya system. The findings of this study suggest that the Rea Vaya is beneficial in that it provides an option in modes of transport for commuters, particularly for people who were historically disadvantaged and were not permitted to reside in the city during the apartheid era. BRT systems are designed to provide a safe, reliable and accessible public transport system. The Rea Vaya system is aimed at providing better public transport, reducing congestion, on public roads, improving the roads and creating jobs. The findings have shown that the Rea Vaya has not been successful in meeting all its aims. The Rea Vaya has not managed to provide an accessible transport system thus far. Traffic in the inner city has not been reduced as a modal shift has not yet occurred. Since the inception of the Rea Vaya system there has been resistance from the Taxi Industry. Despite negotiations and attempts made by the Municipality of the City of Johannesburg to include the Taxi Industry in the Rea Vaya system, by making them shareholders of the system, the findings presented affirms that there is still resentment and resistance from the Taxi Industry towards the Rea Vaya system. The loss of revenue since the introduction of the Rea Vaya has caused a challenge for Taxi owners. Not only is it alleged that the Rea Vaya has affected the Taxi Industry, but the Rea Vaya infrastructure has caused a number of problems for private car users in the City. Private car users are inconvenienced by the designated bus lanes and lack of road signage in the city. These conclusions affirm that the Rea Vaya is not beneficial to all stakeholders in the City of Johannesburg. The experiences and opinions of users and non-users suggest that the system has a number of deficiencies. However some users of the system have benefited socially and economically. For some of the users the Rea Vaya has created a few opportunities; however the poor customer service from bus drivers and station staff was seen as a setback. Transit Orientated development in Johannesburg has not yet taken off. The government’s attempts to create mixed land use through the implementation of corridors of freedom are in its infant stages. Businesses across the Rea Vaya station found the Rea Vaya to have both positive and negative effects on their businesses. Some businesses found that the development of stations have added aesthetic value, however due to the frequency of Rea Vaya buses at stations, commuters would not wait for long periods of time and this resulted in fewer customers for businesses across the Rea Vaya station. The Rea Vaya system has provided a safe and reliable transport system in Johannesburg. However, the system is in its infant stages and has a number of deficiencies as presented in the findings of this study. / Geography / M. Sc. (Geography)

Bus rapid transit: theory and practice in the United States and abroad

Campo, Carlos 18 November 2010 (has links)
Bus Rapid Transit (BRT) is a relatively new mode with a wide range of applications that are still not well understood. Its explosive growth in developing and developed countries has increased its exposure but has led to mostly experimental implementation with mixed results. Therefore, better understanding about the reasons behind BRT implementation success and shortcomings is needed. The objective of this thesis is to evaluate the state of BRT planning under different contexts by assessing how background theory and practical implementation of BRT systems compare. The scope is limited to current a detailed evaluation of 13 case studies in the United States, Canada, Australia, Mexico, Brazil, Colombia, and Ecuador chosen to represent some of the most succesful and established systems in the world. Data was obtaiend from previous research as well as direct reporting from agencies. The evaluation is performed through qualitative and quantitative methods. Qualitative methods classify BRT systems by characteristics and assess the relationship between their implementation and performance using the criteria defined in the literature. Quantitative methods build upon the previous analysis to more precisely assess their performance from both the users' and the transit providers' perspectives. This research found that BRT as a public transit mode has a large room of improvement in terms of design and implementation, since there is a significant variability in performance under similar conditions and a considerable gap between planning best practices and implementation. Also, that planning guidelines are still in an early stage of development and difer in scope and application to a particular context. It also found that its success is not conscribed to developing countries, but that its wide range of applications need to be better adapted to the context they should serve. The findings are significant because they dispel myths about the real potential of BRT and partially identify the reasons behind successes and failures of current systems, such as understimation of implementation times and lack of knowledge about component integration. Further research should approach these issues mainly in two complementary directions. First, it should focus on expanding the case study approach to the newer systems in operation once better data is available. Second,it should further advance the development of theoretical framwork for better operational design based on urban form, as well as an evaluation framework that puts more emphasis on user experience and sustainability. Finally, the findings reinforce that BRT is a distinct mode so that systems that do not meet its criteria should not be named as such.

Ideologies of the everyday : public space, new urbanism, and the political unconscious of bus rapid transit

Zigmund, Stephen Michael 28 February 2013 (has links)
This research uses the recent development of bus rapid transit (BRT) on Cleveland, Ohio’s Euclid Avenue corridor as a case-study to explore the links between public transit, public space, and urban planning. Using Fredric Jameson’s (1981) method of textual analysis from The Political Unconscious, I explore the ways the BRT provides access to a buried class consciousness in the city as well as a “symbolic resolution” between conflicting agendas of development and equity. Contextualizing the new spaces of the BRT using a synthesis of Jameson’s (1984) theorization of postmodernism, Mike Davis’ (1990) militarization of public space, and Michel de Certeau’s (1984) spatial practices, I discuss the ways these spaces are remade by individual users as a vital public space despite the BRT’s embedded market ideology and repressive security apparatus. Additionally, I explore what BRT’s ‘ideology of form’ can tell us about the ideology of the dominant paradigm of planning today, New Urbanism, and use it as departure for a closing discussion of Utopian desires in planning. / text

A decision support tool for capacity designing of BRT stations using discrete-event simulation

Engelbrecht, Louise 12 1900 (has links)
Thesis (MScEng (Industrial Engineering))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The purpose of this study is to investigate the capacity of a proposed bus rapid transit (BRT) station in Cape Town. A bus rapid transit system is a high-capacity public transportation system that carries passengers from one point to another, providing a service that is faster and more efficient than an ordinary bus line. The implementation of these systems is increasing rapidly worldwide, serving as a solution to decrease traffic congestion. The capacity of the proposed bus station, known as the Thibault Station, is investigated in the study by developing a simulation model. The aim is to develop a stochastic simulation model, which represents the flow of passengers throughout the station so that the station capacity can be investigated. By developing a stochastic model as opposed to a deterministic model, elements of uncertainty can be included into the model, thereby representing a system that is closer to the real-life situation under investigation. The majority of BRT systems, as well as past studies undertaken on the Thibault Station, are designed using deterministic calculations. The study commences by researching literature on BRT systems and focuses on the current methods used to calculate station capacity requirements. Thereafter, the concept of simulation is introduced. Simulation is the method chosen to model and evaluate the passenger and bus operations at the Thibault Station. The study presents the methods used to build and verify the simulation model. This is done to familiarise the user with a number of aspects of the model. The model can then be used as a tool to investigate capacity parameters and alternative designs or scenarios. Using the results of these investigations, decisions can ultimately be made regarding the planning and design components of any bus rapid transit station given that the model is adapted. Scenario results, as well as interpretations of performance measurements, are presented at the end of the study. The results can be used for more realistic design of BRT stations using stochastic modelling. / AFRIKAANSE OPSOMMING: Die doel van die studie is om ondersoek in te stel na die kapasiteit van „n hoëspoed bus vervoer stelsel (BRT). Die ondersoek is gebaseer op „n voorgestelde bus stelsel vir Kaapstad. „n BRT-stelsel is „n hoë-kapasiteit publieke vervoerstelsel wat passasiers van een punt na „n ander vervoer, deur „n diens te verskaf wat vinniger en meer doeltreffend is as „n gewone bus stelsel. Die implementering van hierdie tipe stelsels neem wêreldwyd toe en dien as „n oplossing om verkeersopeenhopings te verminder. Die spesifieke busstasie wat ondersoek word staan bekend as die Thibault Stasie van Kaapstad se BRT-stelsel. Die kapasiteit van die stasie word ondersoek deur middel van simulasiemodellering. Die doel is om „n stogastiese simulasiemodel wat die vloei van passasiers modelleer te ontwikkel ten einde die kapasiteit van die stasie te ondersoek. Deur „n stogastiese model in plaas van „n deterministiese model te gebruik, kan elemente van onsekerheid ingesluit word. Dit verteenwoordig dus „n stelsel wat nader aan die werklikheid is. Tans word meeste BRT-stelsels ontwerpe gebaseer op deterministiese berekeninge, asook historiese studies wat onderneem is oor die Thibault Stasie. Die studie begin deur literatuur oor BRT-stelsels te bestudeer en fokus daarna op die huidige metodes wat gebruik word om die vereiste kapasiteit van „n busstasie te bepaal. Die konsep van simulasie word daarna voorgestel. Simulasie is die metode wat in die studie gebruik word om die passasier- en busaktiwiteite van die Thibault Stasie te modelleer en te evalueer. Die studie verskaf die metodes wat gebruik word vir die ontwikkeling en geldigmaak van die simulasiemodel. Gebruikers word op dié manier blootgestel aan die verskillende aspekte van die model. Nadat die gebruikers vertroud is met sekere aspekte van die model, word die model verder uiteengesit en word daar verduidelik hoe dit as „n instrument om kapasiteit parameters en alternatiewe ontwerpe van busstasies te ondersoek kan dien. Die resultate van die model kan gebruik word om beplannings- en ontwerpbesluite van enige busstasie te neem. Aan die einde van die studie word scenarioresultate bekendgestel, asook die interpretasie daarvan. Die resultate kan gebruik word vir meer realistiese ontwerp van BRT-stasies met behulp van stogastiese simulasie modellering.
