It is undeniably true that transportation systems positively impact human life but, the use of transportation systems also emits green house gasses in the environment which leads to global warming. In this day and age, various technologies are being combined with transportation systems, aimed at reducing the global impact of greenhouse gas emissions. The high-speed rail (HSR), which is well-known for low CO2emissions, has continually been improved, especially its model. In this study, the material replacement method is taken to account for a feasibility study on the next model of the HSR....

Urban Development on Railway-Served Land: Lessons and Opportunities for the Developing World

Cervero, Robert
2020

Under the right conditions -- serious traffic congestion, a permissive regulatory environment, and frequent and reliable transit services -- rail transit investments can powerfully shape cities and regions. Rail transit’s city‐shaping powers are due to market forces and policy interventions. By enhancing accessibility (the ability of those living, working, or shopping rail near stops to quickly reach desired destinations) rail services increase the value and desirability of properties in and around stations. Market pressures by themselves rarely produce transit oriented development. To...

Life-cycle Energy and Emissions Inventories for Motorcycles, Diesel Automobiles, School Buses, Electric Buses, Chicago Rail, and New York City Rail

Chester, Mikhail
Horvath, Arpad
2009

The development of life-cycle energy and emissions factors for passenger transportation modes is critical for understanding the total environmental costs of travel. Previous life-cycle studies have focused on the automobile given its dominating share of passenger travel and have included only few life-cycle components, typically related to the vehicle (i.e., manufacturing, maintenance, end-of-life) or fuel (i.e., extraction, refining, transport). Chester (2009) provides the first comprehensive environmental life-cycle assessment of not only vehicle and fuel components but also...

Rail + Property Development: A model of sustainable transit finance and urbanism

Cervero, Robert
Murakami, Jin
2008

Hong Kong has aggressively pursued transit value capture to finance railway infrastructure through its “Rail + Property” development program, or R+P. More than half of all revenues received by the MTR Corporation, the owner-operator of Hong Kong’s largest railway network, come from property development. A wide variety of R+P projects presently exist in Hong Kong. Most focus on housing development though all have some degree of commercial development. Recent generation R+P projects have placed a stronger premium on urban design and quality of pedestrian environments. This has generally paid...

Environmental Life-cycle Assessment of Passenger Transportation: A Detailed Methodology for Energy, Greenhouse Gas and Criteria Pollutant Inventories of Automobiles, Buses, Light Rail, Heavy Rail and Air

Chester, Mikhail
Horvath, Arpad
2007

The passenger transportation modes of auto, bus, heavy rail, light rail and air are critical systems relied upon for business and leisure. When considering their environmental effects, most studies and policy focus on the fuel use of the vehicles, and ignore the energy and other resource inputs and environmental outputs from the life cycles of necessary infrastructures, fuels, and vehicles. The goal of this project is to develop comprehensive life-cycle assessment (LCA) models to quantify the energy inputs and emissions from autos, buses, heavy rail, light rail and air transportation in...

Bus Rapid Transit Impacts on Land Uses and Land Values in Seoul, Korea

Cervero, Robert
Kang, Chang Deok
2009

More and more cities are turning to Bus Rapid Transit (BRT) as a way of cost-effectively expanding public transit services to help relieve traffic congestion, reduce carbon emissions, and increase mobility options for the poor. Because of the inherent flexibility advantages of rubber-tire buses – e.g., unlike rail systems, the same vehicle that functions as a line-haul carrier can also morph into a neighborhood feeder -- BRT is especially suited for many lower density and non- CBD settings.Some of the most advanced and widely heralded BRT services today are found in Latin America, such as...

Urban Densities and Transit: A Multi-dimensional Perspective

Cervero, Robert
Guerra, Erick
2011

This paper investigates the relationship between transit and urban densities in the United States. An analysis of light rail systems finds that a residential density of about 30 people per gross acre near stations is needed to in order to make them among the top 25 percent of rail transit investments in terms of cost effectiveness; for heavy rail systems, the density is 45 people per gross acre. Increasing density around stations would greatly increase ridership, particularly when jobs are located within one-quarter mile of the stations and housing is located within one-half mile....

Direct Ridership Model of Bus Rapid Transit in Los Angeles County

Murakami, Jin
Miller, Mark A.
2009

A Direct Ridership Model (DRM) for predicting Bus Rapid Transit (BRT) patronage in Southern California is estimated. Attributes of bus stops and their surroundings constitute the data observations of the DRM, enabling a fairly fine-resolution of analysis to be carried out on factors that influence ridership. The best-fitting DRM revealed that service frequency strongly influences BRT patronage in Los Angeles County. High intermodal connectivity, with both feeder bus routes and rail-transit services, also significantly induces BRT travel. Population densities also contribute to BRT...

Transportation Policy in Oakland: As It Is and as It Should Be

Parks, Jamie
2013

Oakland has more BART stations than any other Bay Area jurisdiction, numerous mixed-use neighborhoods, and one of the highest bike-to-work mode shares in the country. Yet, the City has failed to fully take advantage of these natural advantages, partially due to the lack of a cohesive vision for the role transportation should play in the lives of Oaklanders. Oakland passed a Complete Streets Policy in 2013 that will allow the City to consider transportation decisions from a broader perspective. The presentation will share updates on several on-going complete streets initiatives, including...
