The Environmental Impacts of Logistics Systems and Options for Mitigation

Sathaye, Nakul
Li, Yuwei

2006

This paper presents a discussion directed at determining the most progressive options for shifting the freight logistics industry towards having more sustainable-oriented goals. The authors first discuss transportation sustainability and the concept of green logistics. This is followed by a discussion on externalities resulting from vehicle emissions and indirect environmental externalities. The problem of environmental externalities is then examined, with focus on emissions and other related data. The authors then examine options for reducing environmental externalities. They discuss...

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...

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...

The Environmental Impacts of Electric Bikes in Chinese Cities

Cherry, Christopher
Weinert, Jonathan
Ma, Chaktan
2007

Electric bikes have captured a large share of trips in many Chinese cities. They provide high levels of mobility and use little energy, two things that Chinese cities need to optimize. However, these benefits come at a cost, particularly emissions from primarily coal power plants and increased lead waste from battery use. Chinese policy makers are struggling with developing appropriate policy that maximizes modal options and mobility and minimizes environmental impacts. Electric bikes use very little electricity and, as a result, emit low levels of pollution per vehicle (passenger)...

Direct Ridership Model of Bus Rapid Transit in Los Angeles County

Cervero, Robert
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...

Accessible Cities and Regions: A Framework for Sustainable Transport and Urbanism in the 21st Century

Cervero, Robert
2005

This paper examines both the principle and analytical possibilities of accessibility as a platform for advancing sustainable transport and urbanism in coming years and decades. Experiences with accessibility planning are first reviewed, followed by a discussion of various measurement and analytical contexts. The paper then uses various policy contexts and case settings to probe the use of accessibility for addressing contemporary urban and regional transportation and land-use themes, including: inter-modal comparisons of job accessibility and their implications for social equity and...

Toward Green TODs

Ververo, Robert
Sullivan, Cathleen
2010

Green Transit Oriented Developments (TODs) shrink environmental footprints by reducing Vehicle Kilometers Traveled (VKT)/ Vehicle Miles Travled (VMT) and incorporating green urbanism and architecture in community designs. Synergies from combining TOD and green urbanism derive from increased densities, which promote transit usage and conserve heating/cooling expenses; mixed land uses which promote non-motorized transportation and limited-range electric vehicles; reduced impervious parking services matched by increased open space and community gardens; and, opportunities for generating solar...

Unintended Impacts of Increased Truck Loads on Pavement Supply-chain Emissions

Sathaye, Nakul
Horvath, Arpad
Madanat, Samer M.
2009

In recent years, the reduction of freight truck trips has been a common policy goal. To this end, policies aimed at influencing load consolidation, load factors and increasing maximum truck weight limits have been suggested and implemented, resulting in higher gross vehicle weights. The purpose of such policies has generally been to mitigate congestion and environmental impacts. However, trucks cause most of the damage incurred by highways pavements. The supply chain associated with pavement maintenance and construction releases significant air emissions, raising the question of whether...
