Efficacy of the Bacteria Encapsulation Concrete Self-Healing Method in a Harsh Environment

Concrete is the most widely used material in construction, offering advantages in terms of moisture and fire resistance, versatility, cost, energy-efficiency, and environmental impact.1 Concrete provides a relatively high level of compressive strength; its tensile strength, however, is fairly low, and concrete members crack on the tension side under the application of small loads. Hence, most concrete systems generally incorporate reinforcing steel to resist tensile.

Environmental Impacts of Oil and Gas Brine Applications for Dust and Ice Control in New York

Transportation agencies are required to treat roads for dust and ice control to ensure adequate safety for travelers. This is commonly achieved through application of solid and liquid chemicals. These materials can be conventional rock salt, brine from rock salt, natural brine, or oil and gas brine. Due to the high cost of treating roads for the removal of snow and ice, in states with active oil and gas wells such as New York, the potential for using this brine to control dust or ice on roads is currently being explored.

Analysis of Curved Weathering Steel Box Girder Bridges in Fire

Bridge fires can present a severe hazard to the transportation infrastructure system. In fact, a nationwide survey by the New York State Department of Transportation (NYSDOT) has shown that fires have collapsed approximately three times as many bridges as earthquakes. Bridge fires are often intense as they may be fueled by gasoline from vehicles that have crashed in the vicinity of the bridge. Additionally, code recommendations and guidelines for fire protection of bridges are lax.

Monitoring Infiltration Capacity of Different Types of Permeable Pavement

The proposed project will monitor infiltration capacity of 3 different kinds of permeable pavement. The objective is to determine 1) how infiltration capacity varies by pavement type; 2) how infiltration capacity has changed over time for each pavement type; and 3) how infiltration capacity varies along a gradient of distance from source of clogging material.

Measuring Parking Intrusion in New York City Neighborhoods using Parking Tickets and Vehicle Plate Registration Data

Parking intrusion occurs when non-residents park on neighborhood streets in order to avoid parking fees while access nearby opportunities (e.g., retails, offices, or sports events). Such intrusion is environmentally undesirable because it invites driving to urban centers with convenient transit services and the worst traffic congestion. It encourages excessive search for parking on neighborhood streets that endangers local pedestrians, cyclists and children.

Port Resilience: Overcoming Threats to Maritime Infrastructure and Operations from Climate Change

Ports are critical element in the global supply chain and any disruption in that transportation system can have significant impacts on the U.S. economy. Climate change and associated sea level rise have the potential to cause significant and frequent damage to the coastal environment if precautions are not taken. The location and nature of a port makes it susceptible to both natural and human-made disasters.

Real-time Estimation of Transit Origin-Destination Patterns and Delays Using Low-Cost Ubiquitous Advanced Technologies

The NYU Poly research team proposes utilizing Bluetooth technology to estimate origin-destination demands and station wait times of users of the MTA New York City Subway system. If the entrance and exit turnstiles at subway stations are equipped with Bluetooth receivers, it is possible to capture O-D information for some percentage of the riders with visible Bluetooth devices. The riders who have electronic devices such as most cell phones, iPods, and computers carry unique information in their devices’ Bluetooth MAC address.

Techniques for Information Extraction from Compressed GPS Traces

Nowadays, GPS devices are routinely installed in motorized vehicles. These devices generate huge volumes of trace (or trajectory) data, with each trace giving the position (latitude and longitude) of a vehicle over time. GPS traces contain information that is valuable to many stakeholders such as transportation planners, policy analysts and business organizations (e.g. trucking industry and taxi companies). Such traces are often compressed to eliminate redundancy and reduce the amount of storage space. When additional data about vehicles (e.g.

Effect of plug in hybrid electric vehicle adoption on gas tax revenue, local pollution, and greenhouse gas emissions

As the price of natural resources and the threat of climate change continue to rise, advancements for cheaper, cleaner, and more efficient power are being made for vehicle use, leading to a wealth of different fuel and powertrain choices for advanced-technology vehicles. Potential alternative fuel pathways include biofuels, electric and hydrogen. Likewise, there are numerous platforms for alternative powertrains, e.g., all-electric, hybrid, plug-in hybrid. There have been numerous efforts by researchers to evaluate different pathways and platforms [1-4].

The Ties that Bind: Developing a Bi-national Transportation-Combined Economic Simulation Model to Assess Security and Policy Implications of US-Canada Border Bridges

The objectives of this research are to understand the economic importance of border bridges on the U.S.-Canada economies, especially involving the various US states proximate to the Province of Ontario, and to simulate various the U.S.-Canada border bridge policy and security scenarios. To this end, we will develop a novel bi-national transportation-combined economic simulation model which contributes to providing hierarchical economic impacts at the state/province or lower levels of the two countries.
