<p>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.</p>

<p>Traffic congestion in Northern New Jersey imposes a substantial operational and monetary penalty on bus service. The purpose of this project was to quantify the additional time and operational costs due to traffic congestion. A regression model was developed that estimates the travel time rate (in minutes per mile) of a bus as a function of the car travel time rate, the number of passengers boarding per mile, and the number of bus tops per mile.

<p>This report documents and summarizes the study &#39;Identification of Traffic Control Devices for Mobile and Short Duration Work Operations,&#39; for the New Jersey Department of Transportation. The study was conducted in three tasks: 1. Literature Search, 2. Evaluation Criteria and Analysis, and 3. Identify Guidelines to Eliminate Driver Inattentiveness, and Design Alternative Strategies and Techniques for Traffic Control.

<p>The objective of this research project was to study mobile and short duration work zone safety with particular attention to the identification of work zone safety devices, information systems for the reduction of safety and congestion, and implementation of innovative techniques to reduce delays and crashes due to work zones.</p>

The project examined the impacts that nighttime
construction activity has upon the workers and sought
to define work standards to mitigate these factors.
Thirty construction workers on four highway
construction projects, along with a focus group of union
laborers, were interviewed for their opinions and
comments to questions on human factors related to
work on nighttime work zones in the fall of 2000. Field
data from interviews were analyzed for human factors
such as sleep deprivation, eating habits, commuting

Roadside rights-of-way are important technical and ecological features of the landscape. Managers of the vegetation in those rights-of-way 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.

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.

The main objective of this project is to assess the impacts of 9/11 upon passenger travel behavior. Models based on Random Utility Theory (RUT) were used to assess behavioral changes. In this context, the random utility models provided the methodological framework for the assessment of behavioral changes, while transportation surveys provided the data to be used in the analyses and model estimation processes.

<p>The NJDOT TMA Grant Program gives qualified TMAs up to $400,000 annually to carry out traffic reduction and clean air initiatives. These dollars have funded the implementation of important national and state mandates. They have given the TMAs a stable financial base, diminishing the need for private funds. These subsidies however, have necessarily moved the TMAs away from a private focus. Consequently, the TMAs have less motivation to champion the needs of their private and local constituents.

Teenage drivers have high crash rates due to immaturity and lack of driving experience. To reduce their accident involvement, many states in the U.S. and countries around the world have implemented graduated driver licensing (GDL) programs.
