The future of personal transportation in megacities of the world
This study examined the future of personal transportation in megacities of the world. Of particular interest was the future role of personal vehicles. To span ranges of geographical, political, and economic factors, the following 15 megacities were included in the analysis: Chicago, New York,...
Interactions of environmental and safety measures for sustainable road transportation
Purpose: This study examined interactions of environmental and safety measures for road transportation. Method: Road-safety effects of various measures targeting environmental problems of road transportation and environmental effects of various road-safety measures were reviewed. Results: The...
Eco-driving strategic, tactical, and operational decisions of the driver that improve vehicle fuel economy.
This report presents information about the effects of decisions that a driver can make to influence on-road fuel economy of light-duty vehicles. These include strategic decisions (vehicle selection and maintenance), tactical decisions (route selection and vehicle load), and operational decisions (...
Connecting and transforming the future of transportation a brief and practical primer for implementing sustainable door-to-door transportation systems in communities and regions world-wide.
Recognizing that no single solution will save the day for transportation in this rapidly urbanizing and increasingly complex world, a groundswell of transportation innovation is arising worldwide. However these innovations are too rarely linked and optimized in a way that can provide a convenient,...
Eco-driving strategic, tactical, and operational decisions of the driver that influence vehicle fuel economy.
This paper presents information about the effects of decisions that a driver can make to influence on-road fuel economy of light-duty vehicles. These include strategic decisions (vehicle selection and maintenance), tactical decisions (route selection and vehicle load), and operational decisions (...
Benefits of recent improvements in vehicle fuel economy on overall fuel consumption and emissions
For the past several years, we have calculated (on a monthly basis) the average, salesweighted fuel economy of all light-duty vehicles (cars, pickup trucks, vans, and SUVs) sold in the U.S. The results indicate that, from October 2007 to September 2012, the average fuel economy has improved by 18...
An optimization approach to occupant safety and fuel economy in vehicle design
A major challenge in automotive design is the creation of safe vehicles with minimal environmental impact. This study presents a modeling framework for evaluating and optimizing body designs for improved occupant safety and fuel efficiency. Vehicle body mass is considered as the main link between...
Has motorization in the U.S. Peaked?
This study examined recent trends in the numbers of light-duty vehicles (cars, pickup trucks, SUVs, and vans) in the U.S. fleet. The analysis considered both the absolute numbers and the rates per person, per licensed driver, and per household. The period examined was from 1984 through 2011. The...
Has motorization in the U.S. peaked? Part 2: use of light-duty vehicles.
The main contribution of this study is an examination of recent trends in distances driven by light-duty vehicles(cars, pickup trucks, SUVs, and vans) in the U.S. fleet. This is in contrast to several other recent studies that analyzed distances driven by all vehicles(including medium and heavy...
The reasons for the recent decline in young driver licensing in the U.S.
This survey examined why a substantial percentage of young adults currently do not have a driverï¾’s license, and the future plans of this group concerning obtaining a license.
