Possibility of Sidewall Collapse of Underground Structures due to Loss of Lateral Support under Internal Blast Loading

For some immersed tube tunnels, the horizontal slab contributes to the structural integrity. If a train running on the slab were subjected to an explosion, which then failed a large area of the horizontal slab, the sidewall might yield under the lateral earth and water pressures. In this study, a three-dimensional Finite Element (FE) model was established to analyze the problem. The dimension and structural characteristics of the model tunnel was taken from a published literature. Three different failure scenarios were analyzed to investigate the risk of side wall collapse.

The Role of Social Media in Improving the Safety and Efficiency of Traffic Operations during Non-Routine Events such as Incidents and Planned Special Events

Social media has become an integral part of modern communication. There is however no clear consensus among transportation managers on how social media could or should be used to collect or disseminate actionable information. To provide guidance on the potential use of social media in transportation, a better understanding is needed of the message content as well as the path taken from the sender to the potential user of actionable information during crises and other non-routine events in the transportation system.

Integrated Incident Management System (IIMS) Web Client Application Development, Deployment and Evaluation: An Evaluation of a Potential IIMS Deployment in Western New York

Incident Management (IM) is an area of transportation management that can significantly decrease the congestion and increase the efficiency of transportation networks in non-ideal conditions. In this study, the existing state of the Integrated Incident Management System (IIMS) is reviewed, additional user requirements and applications are identified, potential obstacles to successful deployment are discussed, and identification of future steps towards deployment in western New York are determined.

Integrated Incident Management System (IIMS) Web Client Application Development, Deployment and Evaluation: Staten Island (SI) Demonstration Project

This evaluation report provides background on the development and findings. The aim of the UTRC project was to develop and deploy Portable IIMS based on Smartphone web applications. Previously, traditional IIMS was deployed in the field vehicles networked to central system. The transition from the vehicle-based IIMS to portable smartphones based applications has enhanced Stakeholders’ experiences and ability to increase usage, and now ready for large-scale deployment. The users and stakeholders-agencies have concluded this effort as a success.

A GIS-Based Performance Measurement System for Assessing Transportation Sustainability and Community Livability

Sustainability and livability in transportation, as the concepts referring to the capability of transportation systems to maintain the well being of our society, have been widely accepted as the critical principles to improve quality of life and health of communities. The research developed a GIS-based performance measurement system for assessing the roles of transportation in achieving these goals.

Metrics, Models and Data for Assessment of Resilience of Urban Infrastructure Systems

This document is a summary of findings based on this research as presented in several conferences during the course of the project. The research focused on identifying the basic metrics and models that can be used to develop representations of performance response that can be used to define resilience in urban environments, and to bring together data resources that can be investigated to understand and validate the interactive behavior of our complex transportation infrastructure systems, including the use of underground space.

Innovative Travel Data Collection Recommendations

This study had the following objectives: 1. To identify and clarify these two emerging effects – real time data and changing culture, 2. To identify the shifts in data collection and transportation modeling that must take place to assist in identifying and forecasting travel behavior, and 3. To discuss the impacts of such operational shifts, both in cost and outcomes to provide NYMTC with the cost and efficacy impacts of incorporating these emerging tools.” To address these objectives, the research team at Albany Visualization and Informatics Lab (AVAIL), led by Dr.

Drainage Identification Analysis and Mapping, Phase 2

Drainage Identification, Analysis and Mapping System (DIAMS) is a computerized database that captures and stores relevant information associated with all aboveground and underground hydraulic structures belonging to the New Jersey Department of Transportation (NJDOT). DIAMS retrieves relevant performance and financial information so that NJDOT can remain compliant with Phase II of the Government Accounting Standards Board Statement 34, which is NJDOT’s sole means of reporting all financial transactions, namely the value of infrastructure drainage assets on an accrual accounting basis.

A Case Study of High Speed Rail in Florida: Implications for Financing Passenger Railways

Between 1981and 2011, the State of Florida and private corporations, sometimes jointly, sometimes alone, made four different attempts to implement very high speed rail lines between Miami, Orlando, and Tampa, on which trains would run at very high speed, between 150 and 220 miles per hour. Yet, at present, the only new passenger line that is likely to begin operations between these cities is not very high speed, and will not run on dedicated track. Why did all the earlier attempts at very high speed lines fail, while a moderate speed line appears likely to succeed?

Panama Canal Expansion: The Effect of Imports and Exports Diverted from California Seaports on the Port of New York and New Jersey

In 2006, the Panama Canal Authority decided to expand the Canal by investing more than $5 billion to accommodate bigger vessels than now to traverse the current facility. Along with the Nicaragua Canal construction that is optimally expected to finish 2019 (Miller, 2014), the widening of the Panama Canal will allow larger tankers to be able to go directly to the East or Gulf of Mexico ports and bypass the West Coast ports where so many imports currently change modes to cross-continental trucks or rail.
