Development of a Portable Remote Sensing System for Measurement of Diesel Emissions from Passing Diesel Trucks

Project Objective:Presently, proposals and regulations are under consideration to require diesel truck operators to either switch to low sulfur diesel fuel or retrofit their engines and exhaust systems with emission control devices that reduce diesel engine emissions. These regulations have direct impact on the nearly 6000 existing trucks serving the two major ports of Los Angeles and Long Beach. Implementation of these regulations should result in significant improvements in local air quality. However, a major […]

Identification and Evaluation of Major Issues Involving the Impact of Global Climate Change on Transportation Systems

Project Objective:There is a dearth of published studies that deal with the implications of long-range climate change in regard to transportation systems. This proposal aims to identify the significant issues likely to be induced by the expected global climate change in so far as transportation systems in the USA are concerned. Not only will the direct climate change effects on engineered transportation infrastructure components be identified and promising solutions suggested, but a clear roadmap will […]

Labor Markets in Goods Movement Occupations in Southern California

Project Objective:Over the last five years there has been increasing focus on both the negative and positive externalities generated by the Ports of Los Angeles and Long Beach. While there is consensus that the ports generate jobs that extend beyond direct employment at the Ports and terminals, there is some controversy over the number of jobs and the earnings potential of those employed in these jobs. Using data from two nationally-representative microdata sets, we will […]

Emergency Traffic Management Tool for the Los Angeles and Long Beach Harbor Area

Project Objective:Since September 11, 2001, transportation agencies and the maritime industry have had to concentrate on safety and security. General awareness has increased, and many protective measures are in place. The United States is a maritime nation. More than 90% of U.S. imports and exports are delivered by ship. Located in one of America’s largest and fastest growing urban centers, the ports of Los Angeles and Long Beach, with their vibrant roadways and intermodal transportation […]

Efficient routing for safety applications in vehicular networks

Project Objective:In recent years, both the car industry and the government have recognized the tremendous promise of vehicular ad hoc network technology in improving the safety of drivers, passengers, and pedestrians. There are a number of envisioned applications, that can both reduce the number of accidents, e.g. via intelligent car to car communication, and reduce the impact of non-avoidable accidents, e.g. via post-crash warnings. The department of transportation and a number of industry consortiums on […]

XML based supply chain integration at the Los Angeles and Long Beach Ports

Project Objective:In recent years internet related technologies such as XML have created new opportunities for electronic communication between different companies. At the same time many companies have changed their business operations in ways that could benefit greatly from increased communication opportunities. However, for historical and other reasons the use of these technologies for communication has been limited at the Los Angeles and Long Beach Ports. Like many other companies terminal operators at the Los Angeles […]

Estimating behavioral changes for transportation modes after terrorist attacks in London, Madrid, and Tokyo

Project Objective:Our objective is to explore behavioral change in demand for public transit after three major international terrorism attacks on public transportation networks: the London bombings (July 7, 2005), the Madrid bombings (March 11, 2004), and the Sarin Gas Attacks in Tokyo (March 20, 1995). The findings of this study will significantly enhance current understanding of the links between risk perception and demand change responses to terrorism on transportation infrastructure. Better understanding of transportation mode […]

Efficient wireless communication in vehicular environments

Project Objective:There is growing interest in the development and deployment of short-range wireless technologies for vehicle-to-vehicle and vehicle-to-infrastructure communication for a wide range of vehicular safety and traffic control applications. This is evidenced by the development of new standards such as the IEEE 802.11p WAVE (wireless access for vehicular environments) operating in a dedicated 5.9GHz spectrum licensed explicitly for such use. In this project, we propose to develop two efficient wireless communication protocols that address […]

Revisiting the Empirical Foundations for Measuring The Capitalization of Access to Transit

Project Objective:There remains little consensus as to the valuation of access to light rail. Indeed, the literature on access includes a wide variety of estimates of access capitalization into surrounding land and property values. While the modal results seems to point to modest benefits to proximity to rail stations, several recent papers suggest these papers may, in fact, be reporting net benefits to a bundle of spatial amenities and disamenities spatially correlated with the stations. […]

Regulation and Response at the San Pedro Bay Ports

Project Objective:The purpose of this research is to analyze responses by the ports and other industry stakeholders to the growing pressures to mitigate the air pollution impacts of port-related trade. Historically the ports have enjoyed significant independence and support from local and state government because of the large economic benefits generated by port-related trade. Public perceptions of port-related trade have changed dramatically since 2000, however, primarily due to growing evidence of health damages associated with […]
