The Politics of Large Infrastructure Investment Decision-Making: The Case of the Second Avenue Subway

Over the past few decades, urbanization and economic growth have intensified the need for more efficient urban and regional transportation, including the expansion and reorganization of existing transportation networks. Given such huge investments and severe constraints on resources such as financial and land, infrastructure projects require a careful prioritization and selection among available alternatives. In reality, project selection appears to be determined as much by politics as by transport-economic considerations.

Impact Assessment of the Regulation of Heavy Truck Operation

The main objective of this project was to evaluate the impact of New York State’s divisible-load permit system for heavy trucks in terms of benefits and costs to society. Under this system, New York State has allowed a fleet of approximately 12,800 power units to operate above the federal limits on gross vehicle weights and axle loads. The system has eleven permit categories corresponding to number of axles, weight limits, and statewide or downstate geographic area of operation.

Water Quality Mitigation Banking

<p>Current practice in New Jersey for mitigating stormwater impacts caused by transportation infrastructure projects is established by NJDEP Stormwater Regulations (N.J.A.C. 7:8). These rules outline specific processes to offset impacts to water quality, groundwater recharge and peak rate of runoff/runoff volume resulting from the addition of impervious surfaces. The rules are written to address impacts of individual projects without specific provisions for addressing cumulative programmatic impacts of multiple projects through &#39;mitigation banking&#39;.

Evaluation of Plastic and Recycled Plastic Composite Piling in Corrosive Soil

In the United States millions of piles are used to support residential, commercial, and transportation structures. There are, however, some problems associated with the use of traditional piling. It is now more commonly required to install piles on corrosive and contaminated soils, due to industrialization. The durability of concrete, corrosion of steel, and deterioration of wood are serious hindrances to

Part 2 - Performance Standards for Assessing Vegetation Management on Rights-of-Way: Case Study of New York State DOT’s Roadside Rights-of-Way Vegetation Management Program

Rights-of-way vegetation managers are increasingly focused on environmental stewardship. Managers are interested in practices that will produce and demonstrate economically-sound, socially-responsible, and environmentally-sensitive decision making and operational practice. Environmental Management Systems have developed over the past decade to frame and advertise organizational efforts in environmental stewardship, but, to date, these systems have been only strategic/tactical in nature. They have not directly pertained to operations and field performance.

Durability of Recycled Plastic Piles in Aggressive Soils

In the United States millions of piles are used to support residential, commercial,
and transportation structures. There are, however, some problems associated with
the use of traditional piling. It is now more commonly required to install piles on
corrosive and contaminated soils, due to industrialization. The durability of
concrete, corrosion of steel, and deterioration of wood is a serious hindrance to
construction in these environments, particularly where high concentrations of
sulfides or chlorides are present.

Cement Hydration and Heat Exchange Modeling for Curing Process of Concrete Pavements and Bridge Decks at Early Stages

This report, written by Gary S. Wojcik and David R. Fitzjarrald of the University of Albany, describes the field campaign and subsequent data analysis for the Route 30 bridge over the South Chuctanunda Creek in Montgomery County, NY. The two purposes of this work were 1.) to make more detailed measurements of the bridge environment than we have done in the past to better understand the energy budget of a curing concrete bridge and 2.) to provide atmospheric boundary conditions to a model of curing concrete.

Cement Hydration and Heat Exchange Modeling for Curing Process of Concrete Pavements and Bridge Decks at Early Stages-Brief

This project involved a field campaign and subsequent
data analysis for the Route 30 bridge over the South
Chuctanunda Creek in Montgomery County, NY. The
two purposes of this work were: 1) to make more
detailed measurements of the bridge environment than
we have done in the past to better understand the
energy budget of a curing concrete bridge and 2) to
provide atmospheric boundary conditions to a model
of curing concrete.
New measurements included direct sensible and latent

Energy Absorbing Fender Systems
Existing bridge fender protective systems technology, used by other states and countries are grouped into six
main categories: 1) Pile supported; 2) Retractable; 3) Rubber; 4) Gravity; 5) Hydraulic/pneumatic; and 6)
Floating systems. A protection system composed of hardcore composite pile dolphins, composite tubular
