Vegetation managers could use a tool to compare cost effectiveness of different non-herbicide and herbicide alternatives for treating roadside vegetation. Such a tool could be used to make informed decisions, better communicate the bases for treatment choices with various stakeholders, and direct research and development activities (focus R&D where the comparisons of different alternatives are interesting, but weak on factual information).

Weigh-in-motion (WIM) systems might soon replace the conventional techniques used to enforce
weight restrictions for large vehicles on highways. Currently WIM systems use a piezoelectric
polymer sensor that produces a voltage proportional to an applied pressure or load. Using this
phenomenon, these systems are already being tested for collecting traffic data, including weigh-inmotion,
measuring vehicle speeds, classifying vehicles by category and counting axles etc. The

Piezoelectric sensors are being tested for collecting traffic data, including weigh-in-motion, measuring vehicle speeds, classifying vehicles by category and counting axles etc. There are two types of these sensors ? polymer and ceramic. Currently WIM systems use a piezoelectric polymer sensor that produces a voltage proportional to an applied pressure or load. The polymer sensors are usually in the form of a long tape or cable embedded within a long block of elastomeric material. These blocks are installed into grooves, which are cut into roads perpendicular to the traffic flow.

Over the last decade, a large number of high capital cost transportation projects
have been proposed for the New York City Region. Many have resulted from addressing
evolving capacity needs, changes in regional demographics and economics, meeting the
improvements necessitated by operating century old subway systems and recognizing the
impact of moving freight in a dense region. But the catalyst for bringing all of these projects
to the attention of the public and all regional agencies was the tragedy of September 11, 2001.

<p>In 1998, the State of New Jersey passed a Graduated Driver Licensing (GDL) law to take effect on January 1, 2001. The law enacted a three stage licensing system; in simplified form this consists of: 1. Special learner?s permit for 16 year olds, during which the new driver must be supervised by an experienced driver over 21; 2. Provisional license for 17 year olds who have completed minimum of 6 months with a learner?s permit, during which the new driver may not drive between Midnight and 5 AM and is restricted in the number of passengers under 21 that may be carried; and 3.

<p>New Jersey started enforcing a graduated driver license (GDL) system on January 1, 2001. The system requires a three-step process for full licensing: learner&#39;s permit at 16 years of age at the earliest; provisional license at 17; and, a basic license at 18. This report is the first phase of an evaluation of the New Jersey GDL system. The number and types of traffic crashes, traffic violations, and license suspensions in New Jersey by age for the years immediately before 2001 were analyzed.

Momentum is growing for an ambitious round of investments in transportation projects in New
York City. At a time of fiscal crisis, and uncertainties over the direction of the economy in
Lower Manhattan and the city as a whole, new transportation infrastructure is increasingly being
seen as critical for the city?s future. Buoyed by calls from elected officials and civic and
business groups, a wide array of government agencies ? including the Metropolitan
Transportation Authority, the Port Authority, New Jersey Transit, the New York State

<p>The New York State Department of Transportat ion (NYSDOT) is developing a comprehensive set of measures that link investments in transportation to the general economic performance of the New York State Economy. The agency would like to understand in particular how NYSDOT investments singularly or in concert with investments by State and Local governments and Public Agencies/Authorities could improve economic competitiveness. As in the rest o f the U.S., transport systems have been designed to link, impact and even stimulate economic activites.

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.

Fiber reinforced polymer (FRP) composites represent an alternative construction
material without many of the performance disadvantages of traditional materials. The use of FRP
as a pile material can eliminate deterioration problems of conventional piling materials in water
front environments and aggressive soils. This paper presents the results of one-year
experimental study conducted to assess the durability of piling made of recycled plastics in
aggressive soils for long term usage in civil infrastructure applications. An accelerated testing
