BUS SYSTEMS for the FUTURE BUS SYSTEMS for the FUTURE Achieving Sustainable Transport Worldwide BUS SYSTEMS FOR THE FUTURE BUS SYSTEMS FOR THE FUTURE Achieving Sustainable Transport Worldwide Cities around the world face enormous problems of transport sustainability. Rapidly increasing populations and vehicle usage have created gridlock and sprawl, even in very poor cities, as well as unacceptably high levels of air pollution, noise, and accident rates. But improvements can be made. This book explores how the provision of better bus services can bring concrete solutions. “Bus rapid transit” systems emerging in Latin America provide fast, reliable and efficient urban travel for large numbers of people. Express busways, employing high- capacity buses and new technologies such as GPS-based bus tracking systems, can conveniently and reliably Worldwide Achieving Sustainable Transport move up to 10 times as many people along a route as can cars – and be profitable. BUS SYSTEMS This book shows how bus rapid transit differs from traditional bus systems and how it can be developed FOR THE FUTURE around the world. There is a detailed look at clean fuels Achieving Sustainable Transport Worldwide and advanced technologies such as “clean diesel”, CNG, hybrid-electric and fuel cells. Case studies are made of six cities and of the steps each might take to encourage more sustainable transport systems. $100 €110 (61 02 26 1 P1) ISBN : 92-64-19806-7 -:HSQBMA=UWW[VU: 2002 INTERNATIONAL ENERGY AGENCY BUS SYSTEMS FOR THE FUTURE Achieving Sustainable Transport Worldwide INTERNATIONAL ENERGY AGENCY page2-16x23 8/04/02 15:20 Page 1 INTERNATIONAL ENERGY AGENCY ORGANISATION FOR 9, rue de la Fédération, ECONOMIC CO-OPERATION 75739 Paris, cedex 15, France AND DEVELOPMENT The International Energy Agency (IEA) is an Pursuant to Article 1 of the Convention signed in autonomous body which was established in Paris on 14th December 1960, and which came November 1974 within the framework of the into force on 30th September 1961, the Organisation Organisation for Economic Co-operation and for Economic Co-operation and Development Development (OECD) to implement an inter- (OECD) shall promote policies designed: national energy programme. • to achieve the highest sustainable economic It carries out a comprehensive programme of growth and employment and a rising standard energy co-operation among twenty-six* of the of living in Member countries, while maintaining OECD’s thirty Member countries.

FOREWORD Rapidly increasing traffic congestion, air pollution, and sprawl are jeopardising the ability of the developing world’s premier cities to achieve sustainability. These problems, present in most large urban areas of developing countries, also account for a substantial share of the expected increase in world oil use and CO2 emissions over the next twenty years. Near-term bus system improvements in these cities – before cars become dominant – could be among the most important and most cost-effective approaches for achieving transport sustainability. Compared to urban transport systems dominated by private vehicles, bus-dominated systems result in much less traffic congestion, lower energy use and emissions, and improved mobility for all social and economic classes. New bus technologies are also emerging that can dramatically reduce emissions and oil use from buses themselves. This book shows how better bus systems and bus technologies can put urban transportation on a more sustainable path around the world.

    BROOKLYN TRANSIT PRIMARY SOURCE PACKET Student Name 1 2 INTRODUCTORY READING "New York City Transit - History and Chronology." Mta.info. Metropolitan Transit Authority. Web. 28 Dec. 2015. Adaptation In the early stages of the development of public transportation systems in New York City, all operations were run by private companies. Abraham Brower established New York City's first public transportation route in 1827, a 12-seat stagecoach that ran along Broadway in Manhattan from the Battery to Bleecker Street. By 1831, Brower had added the omnibus to his fleet. The next year, John Mason organized the New York and Harlem Railroad, a street railway that used horse-drawn cars with metal wheels and ran on a metal track. By 1855, 593 omnibuses traveled on 27 Manhattan routes and horse-drawn cars ran on street railways on Third, Fourth, Sixth, and Eighth Avenues. Toward the end of the 19th century, electricity allowed for the development of electric trolley cars, which soon replaced horses. Trolley bus lines, also called trackless trolley coaches, used overhead lines for power. Staten Island was the first borough outside Manhattan to receive these electric trolley cars in the 1920s, and then finally Brooklyn joined the fun in 1930. By 1960, however, motor buses completely replaced New York City public transit trolley cars and trolley buses. The city's first regular elevated railway (el) service began on February 14, 1870. The El ran along Greenwich Street and Ninth Avenue in Manhattan. Elevated train service dominated rapid transit for the next few decades. On September 24, 1883, a Brooklyn Bridge cable-powered railway opened between Park Row in Manhattan and Sands Street in Brooklyn, carrying passengers over the bridge and back.

  • Southern California Rapid Transit District (SCRTD)
    Los Angeles County Metropolitan Transportation Authority Law ---------------------------------------------------------------------- With corresponding provisions of the Southern California Rapid Transit District Law and Los Angeles County Transportation Commission Law Los Angeles County Metropolitan Transportation Authority California Public Utilities Code Page 2 of 110 Introduction The Southern California Rapid Transit District, also known as the SCRTD or the “District” (1964-1993) was created by the State as the successor to the Los Angeles Metropolitan Transit Authority or “LAMTA” (1958-1964). LAMTA was the first publicly governed transit operator in Los Angeles and also responsible for the planning of a new mass transit system to replace the aging remnants of the transit systems built by Pacific Electric (1899-1953) and Los Angeles Railway (1895-1945). Unfortunately, the LAMTA had no ability to raise tax revenues or powers of eminent domain, and its board was appointed by the Governor, making the task building local support for mass transit improvements difficult at best. Dissatisfaction with the underpowered LAMTA led to a complete re-write of its legislative authority. While referred to in state legislation as a merger, the District law completely overwrote the LAMTA Act of 1957. The Los Angeles County Transportation Commission, also known as LACTC or the “Commission” (1977-1993) was created by the State in 1976 as a separate countywide transportation planning agency, along with transportation commissions in San Bernardino, Riverside, and Orange counties. At the time the District was initially created, there were no transit or transportation grant programs available from the State or Federal governments. Once funding sources became available from the Urban Mass Transit Administration, now the Federal Transit Administration, the California Transportation Commission, and others, the creation of county transportation commissions ensured coordination of multimodal transportation planning and funding programs.

  • Buses – Global Market Trends
    2017 BUSES – GLOBAL MARKET TRENDS Markets – Competition – Companies – Key Figures Extract from the study BUSES – GLOBAL MARKET TRENDS Markets – Competition – Companies – Key figures In all regions across the globe, buses remain the most widespread public transport mode. Their demand goes hand in hand with several, mostly region-specific factors, including demographics, increasing mobility of people and environmental awareness, as well as public funding. Buses are comparatively to other transportation modes cheap and easy to use, since their use does not necessarily require the implementation of a specific infrastructure. This makes buses ideal vehicles for both short- and long-distance services. Based on the current developments, this Multi Client Study offers a comprehensive insight into the structure, volumes and development trends of the worldwide bus market. In concrete terms, the market study “BUSES – GLOBAL MARKET TRENDS” includes: A look at the worldwide market for buses differentiated by region An analysis of the relevant market data including present and future market volumes Information concerning the installed fleet and future procurement potential until 2022 An assessment of current developments and growth drivers of the worldwide bus markets in the individual regions An overview of bus manufacturers including an analysis of the market shares, financial backups as well as a brief description of the current product portfolio and strategy outlook A list of the major production facilities in each of the regions including product range as well as production capacities Presentation of the development stage of alternative propulsions, their manufacturers and their occurrence worldwide The study is available in English from the August 2017 at the price of EUR 3,400 plus VAT.

INTRODUCTION 1.1. Background Populations in most developing countries are increasing much faster than car ownership levels and therefore an increasing proportion of the population is dependent on public transport except for very short journeys. In most countries, walking is the most common mode of travel for distances of up to one or two kilometers in urban areas and much further in rural areas. Those who own bicycles tend to use them for journeys of up to about eight kilometers, beyond which public transport is preferred mode. Public transport also provides an alternative to those who have private transport, but are sometimes deterred from using it by traffic congestion, parking difficulties or problems in accessing certain streets, although in practice it is relatively unusual, particularly in developing countries, for car owners to use public transport to any significant extent. However, in many developing countries families tend to be large, so that even if these is a car belonging to a household, most members of the family are still likely to use public transport for at least some of their travel (Iles 2005) Public transport is therefore vital for the vast majority without access to private transport. There is need for personal mobility, in particular for access to employment opportunities, but with low income levels affordability is a common problem, while the services provided are often regarded as inadequate.

Surabaya is the second biggest city in Indonesia, and Sidoarjo is a regency close to Surabaya, where many people live in but they work in Surabaya. More and more citizen of Surabaya and Sidoarjo use motorcycle taxi, either conventional service or online service so call as “ojek”, operated by the company called as GO-JEK. The purpose of this research is to evaluate the performance of GO-JEK in Surabaya and Sidoarjo based on user point-of-view and to observe what factors that influence the users in selecting either conventional or on-line ojek. The methods used are the Importance Performance Analysis (IPA) and the Stated Preference Technique. The IPA shows that there are 3 factors that have to be improved: firstly, driving manner, secondly, attention to maximum capacity and thirdly, helmet for the passenger. The Stated Preference Analysis shows that there are two major factors affecting the choice whether GO-JEK or conventional ojek, these are trip cost and waiting time to pick up by the ojek. 1. Introduction Surabaya is the second biggest City in Indonesia, with the population of 2.5 million. Sidoarjo is a regency that has a borderline with Surabaya, where many people live in but they work in Surabaya.

    Effects of Buy America on Transportation Infrastructure and U.S. Manufacturing Updated July 2, 2019 Congressional Research Service https://crsreports.congress.gov R44266 SUMMARY R44266 Effects of Buy America on July 2, 2019 Transportation Infrastructure and Michaela D. Platzer U.S. Manufacturing Specialist in Industrial Organization and Business In 1978, Congress began placing domestic content restrictions on federally funded transportation projects that are carried out by nonfederal government agencies such as state and local William J. Mallett governments. These restrictions, which have changed over the years, are commonly referred to as Specialist in the Buy America Act, or more simply, Buy America. Although there has been ongoing Transportation Policy congressional interest in domestic preference policy over the years, statements and actions by the Trump Administration about reinvigorating domestic manufacturing and investing in infrastructure have stimulated renewed interest in Buy America. Buy America refers to several similar statutes and regulations that apply when federal funds are used to support projects involving highways, public transportation, aviation, and intercity passenger rail, including Amtrak. Unless a nationwide or project-specific waiver is granted, Buy America requires the use of U.S.-made iron and steel and the domestic production and assembly of other manufactured goods, particularly the production of rolling stock (railcars and buses) used in federally funded public transportation and Amtrak’s intercity passenger rail service. A separate law requires that at least half the value of products imported by sea for federally supported transportation projects be transported in U.S.-flag ships. This report examines the effects of Buy America on iron and steel manufacturing, rolling stock manufacturing, and transportation.

  • Jakarta's Bus Rapid Transit System Indonesia
    Jakarta’s Bus Rapid Transit System CASE STUDY Indonesia | March 2016 "Transport in Asia and the Pacific faces a web of issues that need a strategic solution... Countries across the region have to contend with road safety, air pollution, social sustainability, climate change impacts, lack of public financing, decrepit infrastructure, and even cross-border bottlenecks, among others.” - James Leather, Co-Chair, ADB Transport Community of Practice Hoping to improve the worsening traffic situation in Jakarta, Sutiyoso—then Governor of Jakarta—bit the bullet and pushed for the construction of the Jakarta Bus Rapid Transit (BRT) system in 2001. With worsening traffic congestion and growing population of 8 million in 2000, BRT was thought as the ultimate solution to the traffic woes of people in the capital of Indonesia. The BRT masterplan is projected to have a busway network consisting of eleven corridors. The system is a closed trunk system without a functioning feeder system. The first corridor of Jakarta’s BRT of around 12.9 km, essentially consisting of a dedicated lane and loading platforms for large buses in the inner side of city streets, began operations in early 2004. Initially, the system ran well and showed good results—patrons’ travel time was reduced by an average of 20 minutes through a clean and convenient transport system that had longer operating hours. Pre-launch objections from affected bus operators and the driving public had disappeared. However, problems on the operational and managerial aspects of the project began to crop up a few months after the BRT was launched. Months after the BRT launch, Governor Sutiyoso—then governor of Jakarta—listened intently at the problems presented by the various stakeholders of Jakarta’s Bus Rapid Transit (BRT) System.
