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.

As one of the major causes of fatalities and injuries in the U.S., motor vehicle crashes and their influential factors have been analyzed extensively in the last few decades. However, most existing studies on crashes primarily focus on passenger vehicles and highway segments. The studies on truck related safety issues in metropolitan areas are largely underexplored. Meanwhile, as part of the effort to relieve congestion in New York City, an off-hour delivery program is being implemented.

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.

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.

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.

The objective of this project was to present an assessment of how social media is used to support the management of traffic operations during non-routine events. To accomplish this, the authors reviewed literature related to social media use for transportation, and for disasters and crises. Further, the team reviewed social media sites and data provided by various transportation agencies, in particular the messages related to traffic and non-routine events.

The Carrs Creek culvert collapsed during the Mid- Atlantic States Flood in June 2006. Rapid construction with geofoam fill enabled partial reopening of I88 by Labor Day. Soon after opening, excessive settlements developed and the geofoam was replaced with lightweight aggregates and I88 was again re-built. Figure 2 Excessive settlement and removal of the geofoam fill.

The nighttime driving environment, consisting of roadway illumination, signs, vehicle lighting and markers, delineators and flashing lights, can be complex or even confusing for both pedestrians and drivers. The nighttime construction environment is even more complex and even chaotic because of the added presence of workers, construction equipment and bright lights (which are sometimes flashing). Work zones at night often involve changing conditions and new traffic patterns that are unfamiliar to drivers.

Exposure to fine particle pollution can cause premature death and harmful cardiovascular effects such as heart attacks and strokes, and is linked to a variety of other significant health problems. NYC, one of the most populous urban areas in the US has been mentioned frequently both as problematic in terms of concentrations of particulate matter and asthma rates, and as a success story in terms of air quality management.
