The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatig...

As America’s population continues to age, the number of pedestrians with mobility or vision disabilities will increase. The focus of this project was to evaluate ultra-wideband (UWB) radio signaling for the purpose of tracking individuals as they c...

Most algorithms are run-to-completion and provide one answer upon completion and no answer if interrupted before completion. On the Tech Report hand, anytime algorithms have a monotonic increasing utility with the length of execution time. Our invest...

Electric vehicle (EV) batteries have significantly improved since their inception. However, lifetime of these batteries is still strongly dependent on the usage profiles. This report describes aspects of EV battery utilization, and their impact on ba...

Combined sewer overflows (CSOs) are a water management issue for Onondaga County and the city of Syracuse, NY. To reduce them, the County is investing in green infrastructure (GI). GI technologies such as green roofs, rain gardens, and bioswales are ...

A smart driving system must consider two key elements to be able to generate recommendations and make driving decisions that are effective and accurate: The environment of the car and the behavior of the driver. Our long-term goal is to develop techn...

Highway construction disturbs soil, which must be stabilized to prevent migration of soil particles into water bodies. Stabilization is enforced by law, regulation, and a permit system. Stabilization is most efficiently attained by reestablishment of...

An evaluation of renewable hydrogen production technologies anticipated to be available in the short, mid- and long-term timeframes was conducted. Renewable conversion pathways often rely on a combination of renewable and fossil energy sources, with ...

With annual gross domestic product (GDP) of more than 2.4 trillion dollars, the State of California plays a major role in the nation’s economic growth and international trade. It is the largest state economy in the US and accounts for about 14% of ...

With the apparent evolution towards more extreme weather including hurricanes and tropical storms, state transportation agencies are realizing the need for adaptive infrastructure systems that can react and adapt to these events. However, dramatic ch...

This research project developed three types of products for study: woolen erosion control blankets (ECBs), wool incorporated into wood fiber compost at a 40:1 ratio (compost to wool, by weight), and wool incorporated into silt fence. The project, sup...

Why do people travel? Underlying most travel behavior research is the derived-demand paradigm of travel analysis, which assumes that travel demand is derived from the demand for spatially separated activities, traveling is a means to an end (reaching...

In this project, a bridge maintenance and preservation program was developed for the City of Columbia, Missouri. The program focuses on practical and implementable technologies and procedures that can be applied to extend the service lives of the bri...

Natural disasters such as a hurricane can cause great damages to the transportation networks and significantly affect the evacuation trip operations. An accurate understanding and measurement of the network vulnerability can enhance the evacuees’ p...

Effective signage that is easy to understand facilitates safe driving through a work zone. While the guidance for work zone signage in the Manual on Uniform Traffic Control Devices (MUTCD) is suitable for many conditions, there may be instances where...

Statistics show that in the U.S., there are about 38 million licensed drivers over age 65; about 1/8 of our population. By 2024, this figure will DOUBLE to 25%. The current research is intended to address the driving capabilities of our older populat...

This project is a collaboration between Portland State University (PSU) and the Center for Infrastructure Transportation & Environment (CITE) at Rensselaer Polytechnic Institute seeking to develop performance measures for assessing the impacts of soc...

The ever-increasing processing speed and computational power of computers and simulation systems has led to correspondingly larger, more sophisticated representations of evacuation traffic processes. Today, micro-level analyses can be conducted for m...

The structural deterioration of aging infrastructure systems and the costs of repairing these systems is an increasingly important issue worldwide. Structural health monitoring (SHM), most commonly visual inspection and condition rating, has proven t...

Automated and connected vehicles (ACV ) and, in particular, autonomous vehicles have captured the interest of the public, industry and transportation authorities. ACVs can significantly reduce accidents , fuel c onsumption, pollution and the costs of...
