Extreme weather conditions play a vital factor in the deterioration of the national transportation infrastructure including pavements. Freezing and thawing of the pavement sections is one of the most critical processes resulting from these extreme weather conditions. In addition to negatively impacting the structural integrity of the pavement layers, frozen pavement surfaces increase highway risks and decrease mobility of people, goods, and first responders.

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.

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.

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.

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.

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.

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.

The primary objectives of this research study are to deploy low-cost portable and integrated multi sensor systems for data-driven performance evaluation of urban transportation networks and 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.
