China's Urban Transportation System: Issues and Policies Facing Cities

Cherry, Chris
2005

China is the most populous country in the world. With a population of 1.3 billion, meeting the housing and transportation needs of this vast country are on the forefront of the political and academic agenda in China and throughout the world. China has experienced phenomenal economic and social growth and as a result the Chinese have desired more mobility and living space. The effects of these desires are beginning to be seen in new auto oriented ex-urban developments that have larger living spaces than the traditional urban centers and whose road infrastructure is developed to support high...

Evaluation of Traffic Data Obtained via GPS-Enabled Mobile Phones: the Mobile Century Field Experiment

The growing need of the driving public for accurate traffic information has spurred the deployment of large scale dedicated monitoring infrastructure systems, which mainly consist in the use of inductive loop detectors and video cameras. On-board electronic devices have been proposed as an alternative traffic sensing infrastructure, as they usually provide a cost-effective way to collect traffic data, leveraging existing communication infrastructure such as the cellular phone network. A traffic monitoring system based on GPS-enabled smartphones exploits the extensive coverage provided by...

Innovative Bus-Lane Deployments in Amman: Proposed Field Experiments

Guler, Ilgin
Cassidy, Michael
2010

Innovative strategies for deploying bus lanes are proposed for field tests in Amman, Jordan. The objective is to reduce delays to buses in the network while minimizing delays to other vehicular traffic. The proposed strategies may be far better options than conventional, static bus lanes, given the test site’s large car demand and low bus frequency. The experiment is designed to be conducted in simple, safe ways, without the need for investment in permanent infrastructure.

Residential Relocation and Commuting Behavior in Shanghai, China: The Case for Transit Oriented Development

Cervero, Robert
Day, Jennifer
2008

This paper examines the effects of residential relocation to Shanghai’s suburbs on job accessibility and commuting, focusing on the influences of proximity to metrorail services and neighborhood environments on commute behavior and choices. The policy implications of the research findings on the planning and design of suburban communities in large cities like Shanghai are addressed in the conclusion. Our research suggests that TOD has a potentially important role to play in placing China’s large, rail-served cities on a more sustainable pathway.

Dual Influences on Vehicle Speeds in Special-Use Lanes and Policy Implications

Jang, Kitae
Cassidy, Michael J.
2011

Slow speeds in a special-use lane, such as a carpool (HOV) or bus lane, can be due to both high demand for that lane and slow speeds in the adjacent regular-use lane. These dual influences are confirmed from months of data collected from all freeway carpool facilities in the San Francisco Bay Area. Both influences hold for other types of special-use lanes, including bus lanes. New US regulation stipulating that most classes of low-emitting vehicles, or LEVs, be banned from slow-moving carpool lanes. While LEVs invariably constitute only about 1 percent of the freeway traffic demand in the...
