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
Since the signing of the North American Free Trade
Agreement (NAFTA) in 1993, rapid growth in crossborder travel has stretched the capacity of the border
transportation network. Heightened security since
September 11, 2001 and expedited clearance initiatives
have also placed new demands on the infrastructure.
In the last 10 years, New Jersey has invested heavily in its transportation infrastructure, and numerous additional projects are planned or proposed for the next decade. Collectively, these projects have significantly improved accessibility in northern New Jersey. Highway and commuter rail travel times have dropped throughout the region as projects such as Midtown Direct and the completion of Interstate 287 connected networks and provided commuters with new travel choices.

<p>The New Jersey Department of Transportation (NJDOT) is currently facing a significant challenge in keeping Intelligent Transportation Systems (ITS) at a high level of availability at the Transportation Operation Center North (TOC North) and Transportation Operation Center South (TOC South). As more and more components are added to the ITS infrastructure, system administration, system management and system operational support become very critical for TOCs. This project was initiated to review current issues facing NJDOT and investigate practices of the other states?
The objective of this research was to perform evaluation tests related to the transmission of digitized video signals over ISDN between a video traffic reporting camera and a traffic management center. The quality of the received video signals was assessed for effectively monitoring the traffic conditions. An evaluation plan was developed which consisted of a market survey of current video-transmission options, an identification of the hardware specifications for the ISDN connections, and a description of the tests to be performed.
The competitiveness of the Port Authority of NY & NJ is dependent on intermodal freight movement through the port. This project provides an analysis of the efficiency of the Port's intermodal movements. The analysis will focus on the objective of keeping the cost of movement at a minimum while at the same time providing for maximum efficiency. The project is divided into three phases: I. crane performance (completed), II. infrastructure access and infrastructure access (near completion) and III. logistics operations of marine container terminal (the present proposal).
This research project is to assess the roles and responsibilities of the Regional Information Technology organizations of New York State Department of Transportation (NYSDOT). The Information Technology (IT) resources of NYSDOT are organized using a matrix structure. The Main Office Information Technology Bureau has an advisory role in relationship to the Regional Information Technology organizations. In order to better understand the roles and responsibilities of the Regional Information Technology organizations, their resource needs must be identified and documented.
The purpose of the following research was to determine whether conspicuity of an illuminated traffic signal lens could be increased with a modulating incandescent light source. Experiments were conducted both in the laboratory and a controlled field setting under normal and degraded viewing conditions using both static and dynamic testing situations.
Delays caused by traffic signals and by street traffic congestion
increase bus-operating costs and degrade transit service quality.
Bus signal priority is an attempt to minimize or eliminate delays
to buses at a signalized intersection by temporarily altering the
traffic signal phase so that an approaching bus receives a green
phase when it arrives. The potential savings in bus travel times
can allow buses to maintain its schedule and provide better
reliability in travel times. Although signal priority has proven to
