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 polymer sensors are usually in the form of a long tape or cable embedded within a long block of elastomeric material.

Recruiting entry-level civil engineers and information technology specialists has become more competitive and the New York State Department of Transportation is experiencing difficulty in attracting people to these positions. Compared to the private sector, NYSDOT’s entry level salaries are lower but rise more quickly. NYSDOT believes their benefit package is better, however, this has never been quantified. If their benefit package is more valuable than that of NYSDOT’s competitors, that would offset lower starting salaries and be an attractive component of a total compensation package.

A Virtual Container Yard (VCY) is a mean of developing a shared resource information system to match empty equipment needs through the adoption of next generation internet and new technology information platforms. The project examines the feasibility of developing and operating a Virtual Container Yard to serve the freight and maritime community in the NY-NJ region. Definition of user requirements and potential business and institutional impediments in successfully establishing the system are identified.

The NYS DEC has required the use of retrofit technologies for various state agency, state public authority, and regional public authority heavy duty vehicles, as well as heavy duty vehicles used on behalf of such agencies and authorities. This report was compiled to assist NYS DOT in its efforts to comply in the most cost effective manner possible, without compromising its core functions.

Urban subway systems remain among the most susceptible to a terrorist attack by biological or chemical agents (BCA) because they are heavily trafficked and have limited points of egress. The combination between efficient creation of casualties and anonymity afforded to terrorists make subways attractive targets. However, the disproportionate amount of passengers to subway employees, limits the ability of transit workers to identify suspicious activity.

Protecting the safety of construction and maintenance field crews and motorists on roadways is the top priority of the New Jersey Department of Transportation (NJDOT) and the Federal Highway Administration (FHWA).  More than 40,000 people are injured each year as a result of motor vehicle crashes in work zones.  In addition, fatalities from work zone crashes have increased more than 50 percent in the last 5 years.

The objective of this research is to perform evaluation tests related to the transmission of digitized video signals over ISDN and/or T-1 lines 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.

This work aims to develop statistical models for ultrafine/fine particle number emission rates from a diesel bus, to evaluate the explanatory power of engine operating variables. Emissions were recorded by using on-board instrumentation in two types of real-world driving conditions: a freeway commuting route and a within-city-limits bus route, with stop and go due to intersections and bus stops. To reduce the risk of drawing spurious conclusions, three replications of the experiment were performed and linear models were estimated using the robust-to-outliers quantile regression method.

The airport access project addresses a longstanding problem affecting New York City travelers and residents, as well as out-of-town travelers. The project plans to link JFK International Airport to two transit terminals, Jamaica Station and Howard Beach Station. It is expected that over 34,000 passengers and employees will use the light rail system annually.

Durability of concrete bridge decks to mechanical and environmental effects is examined for the purpose of evaluation of effects of blacktop resurfacing of bridge decks. Aggressive environmental actions on reinforced concrete are described, classified and equivalent environmental loads presented. To explain effects of aggressive environmental loads, concrete transport properties dependent on: concrete structure, external effects, mechanisms in concrete, and chemical reactions of aggregates are discussed in detail.
