Development of a New, Effective and Low-cost Media for Sustainable Management of Polluted Road Stormwater in Highly Urbanized Areas: Wood Mulch C oated with Aluminum-and Iron-Based Water Treatment Residuals

The goal of this project was to develop a new, effective and low-cost media for sustainable management of polluted road stormwater in highly urbanized areas. The overarching objective of this study was to provide the scientific basis for the development and utilization of a novel media consisting of wood mulch coated with a recycled solid waste -- water treatment residuals (WTR) -- for the removal of multiple pollutants (namely, Cu, Pb, Zn and P) from urban road runoff.

Securing Inter-Vehicular Networks with Time and Driver Identity Considerations

The exchange of information in a timely fashion is critical to accident prevention in transportation systems. Research has demonstrated that anticipating future collisions by as little as half a second before impact could lead to a 60% decrease in traffic accidents. Moreover, in July of 2015, researchers demonstrated a remote exploit of a commercially available vehicle from 10 miles away while it was on the highway, leading to the recall 1.4 million vehicles; this represents the first known automotive recall due to a cyber-security vulnerability.

Dynamic Bus Routing Problem for Evacuation

Evacuation is an important preventative decision before disaster occurs. Evacuation process has heavily dependent on automobile. While, in recent years, public transit attracts more and more attention but has been extensively used in evacuation planning. This paper proposed a one-stage multiclass evacuation model based on Cell Transmission Model(CTM) where evacuation buses is assigned to dangerous area to evacuate people.

Accelerated Aging of Asphalt by UV-Oxidation

The aging of asphalt binder due to UV-oxidation is a phenomenon that affects the durability and performance of asphalt pavements. This report documents results of accelerated laboratory UV-oxidation tests that have been conducted. Thin-film asphalt binder samples have been oxidized using fluorescent UVA and UVB lamps, and the degree of oxidation was determined by measuring the rotational viscosity of the aged binder. The results show that the viscosity increases with the UV-exposure time.

Adaptive Evacuation Transportation Planning Under Uncertainty

The objective of this research project is to deliver a real-time, adaptive evacuation system for cascading events (e.g., hurricanes, following flooding, and following aftershocks). To realize this goal, the PI synthesized the existing information (e.g., flood inundation scenarios, human mobility information such as location-based social media data, U.S.

Recommendations for Improving Fire Performance of Steel Bridge Girders

Infrastructure risk due to fire has been well documented. In particular, bridges in the urban environment are susceptible due to low overhead clearances on overpasses, existing simple spans with no redundancy, due to low overhead clearances on overpasses, existing simple spans with no redundancy, narrow lane widths and general alignment congestion. Although the risk is significant, the current AASHTO Bridge Design Specification does not include provisions for design due to fire conditions.

Portable and Integrated Multi-Sensor System for Data Driven Performance Evaluation of Urban Transportation Networks

The primary objectives of this research study are (1) to deploy some promising low-cost portable and integrated multi sensor systems for data-driven performance evaluation of urban transportation networks and (2) to develop a system capable of real-time remote monitoring of external changes, such as air quality, noise, humidity, temperature, and crowd and vehicular densities in an urban setting.

The Socialization of Travel: The Effects of Social Networks on Resiliency

With improvements in mobile information and communication technologies (ICT) and the increasing presence of innovative mobility services such as car-sharing, bike-sharing and ride-sourcing services, regional planning organizations (MPOs) critically consider these travel options in their strategic planning. The transportation modeling community increasingly view these scenarios as two-sided markets, where the service providers (suppliers) endogenously adjust their aspirations and behavior in relation to a dynamic traveler demand response.

Mitigation of Transportation Induced Vibration Using Seismic Metamaterials

Transportation systems create new technical and environmental challenges including noise and ground vibration, which affect ambient architectures, quality of life, and sustainability of the communities. Noise and vibration assessments become key elements of the environmental impact assessment process for mass transit projects, and noise and vibration are among the major concerns with regard to the effects of a transit project on the surrounding community.
