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.

Prior research using the GIFT model generated annual emission totals and truck count estimates for routes and road segments associated with the transport of materials and wastes from natural gas wells in the Marcellus Shale region. Road segments with the highest estimated truck counts (> 25,000) were identified and used to select 72 regions, representing the boundaries of 72 USGS quadsheets, for further analysis using the emission dispersion model AERMOD.

In the coastal zone, seaports and their intermodal connectors are key types of infrastructure that support the global supply chain, provide regional economic activity, local transportation system services, and community jobs. The protection of coastal communities and their ports has been taken for granted during a prolonged period of climate stability. Recently there are growing concerns that a new period of climate change and severe weather events is emerging. Communities and their waterfront facilities are vulnerable to disruptions.

One of the main tools that the Department of Transportation (DOT) of each state in the United States should have to support their work zone activities is a sound model that produces adequate work zone schedules for roadway maintenance and construction projects; this should be able to to produce reliable estimates of the impacts on traffic flow characteristics due to work zone activity.

Hurricane Sandy revealed the higher-risk vulnerability to natural hazards of civil infrastructure systems in coastal megacities such as New York. In particular, critical deficiencies in the NYC metropolitan area’s transportation system emerged after Sandy. Unfortunately, experts predict that future sea level rise and storms will exacerbate the problems caused by these deficiencies. There are thus several challenges to improving strength and resilience of transportation systems.

The goal of this project is to provide statistical inference for the community’s willingness to pay for improvements in the resiliency to extreme events of the transportation system in New York City. This objective seeks to provide better tools for better informing planning investments to improve both resilience and security of transportation infrastructure and services.

Pedestrian safety is a critical element of urban transportation. A review of published literature, as well as real-world demonstration activities, indicate that bollard-level crosswalk lighting has excellent potential for enhancing pedestrian visibility and improving safety at crosswalks, particularly where the presence of a crosswalk might not be expected by approaching drivers.

Developing techniques for extracting information requires a good understanding of methods used to compress the traces. Many techniques for compressing trace data consisting of position (i.e., latitude/longitude) and time values have been developed. Since current vehicles are equipped with many on-board instruments, traces generated by such vehicles contain many attributes in addition to position and time. The problem of compressing such multi--atribute traces is currently being studied by a number of researchers.

Although the nuclear density method has been widely used in the compaction measurement of both soils and asphalt pavements, its accuracy for asphalt pavements is not as good as that for soils. Due to this issue, many disputes have incurred in construction projects, which resulted in replacement of the nuclear test method with the core sample method in many state DOTs for quality assurance or acceptance including the DOT Region II states. However, most contractors still use it on quality control as a fast and economic test method.
