Computational Modeling of Driver Speed Control with its Applications in Developing Intelligent Transportation Systems to Prevent Speeding-Related Accidents

Speeding is commonly recognized as exceeding the posted speed limits or driving too fast for conditions. National Center for Statistics and Analysis (NCSA) reported that speeding is a contributing factor in about one-third of all fatal traffic crashes in the United States and costs society an estimated $40 billion annually in 2004. In the U.S.

Characterization of Fatigue Properties of Binders and Mastics at Intermediate Temperatures using Dynamic Shear Rheometer

G*sin(δ) is the SuperPAVE binder specification for fatigue. This number has been studied in recent times and has been found to be an inaccurate measurement. Tests to determine a more appropriate test for fatigue were conducted, leading to the Dissipated Energy Ratio (DER) and the recent Linear Amplitude Sweep (LAS) tests.

Data Driven Performance Measures For Effective Management of Complex Transportation Networks

In the past, transportation data was collected through the limited deployment of infrastructure-based sensors and manual spot counts and surveys. Massive on-line data being collected on a nearly 24/7 basis enable researchers and transportation managers alike to quantify a number of realistic “performance measures” that allow transportation agencies to make timely and proactive decisions.

Lessons from Hurricane Sandy for Port Resilience

New York Harbor was directly in the path of the most damaging part of Super Storm Sandy causing significant impact on many of the facilities of the Port of New York and New Jersey. The U.S. Coast Guard closed the entire Port before the storm hit on October 28, 2013. It was not fully reopened to vessel traffic until November 4th. Even though the waterways were open, numerous terminals and facilities did not resume their operations for several weeks.

Prediction Of Impact On Transportation System Due To Coastal Flooding Under Climate Change Conditions

Global warming and climate change are reshaping our world in many ways. One of their most obvious evidences is sea level rise due to melting of polar glaciers and arctic ice. It is estimated that global sea level rise is at an alarming rate of 0.18cm/yr during 1961-2003, it is even higher at 0.3cm/yr during 1993- 2003, and research estimates that sea level could range from 0.8 to 2 m by 2100 under glaciological conditions.

Finite Element Model Updating and Damage Detection for Bridges Using Vibration Measurements

The continued functionality of a nation’s infrastructure systems, e.g. bridges, is a necessary pre-requisite to her continued social and economic development. However, in about 15 years, 50 percent of our bridges will be over 50 years old, inducing an unprecedented commitment of both financial and human resources. Hence, a successful Structural Health Monitoring (SHM) strategy, providing reliable, economic and easy to conduct inspections, is essential to engineers and government authorities responsible for the up-keeping of such systems.

Towards Socially and Economically Sustainable Urban Developments: Impacts of Toll Pricing on Residential Developments

The goal of this research is to investigate the effects of road pricing on residential land use choices and to help select pricing policies that foster socially and economically sustainable residential development in urbanized residential areas. Under this goal, a residential land use choice model in logit form with shared aggregated data was developed. The model was designed to assess the impacts of various toll pricing policies and the resulting accessibility on a residential land use choice pattern.

Seismic Evaluation and Retrofit of Deteriorated Concrete Bridges

The findings of this investigation suggest the need for seismic retrofit of deteriorated reinforced concrete bridge columns, particularly, those with corroded lap splice in the longitudinal reinforcement. The study also suggests the need for retrofit of corroded pedestal over piers and abutments, as they may cause sudden unseating of girders.
