The estimation of future freight needs requires the use of network and freight demand models. When characterizing freight demand, basic data are sought to appropriately model the decision processes associated with freight generation, distribution, and consumption. In this context, freight origin-destination (OD) matrices are one of the most important data a planner could have, which is why a significant amount of effort, time and money is spent on their estimation.

Bridges in the USA have been an integral part of the Interstate Highway System growth. Until the mid to late 1970s, all steel bridges were protected from corrosion by paint coatings containing lead and chromate. The majority of the steel bridges in the interstate system were constructed between 1950 and 1980. Most of these structures have paint coatings containing lead and chromate (FHWA-RD-89-127). A large percentage of the existing steel bridges are currently reaching a critical level of deterioration.

The project is designed to assess and evaluate the suitability of sites for the development of facilities to support waterborne transportation of people and freight in the New York metropolitan region. The study effort will be guided by a Steering Committee drawn from members of NYMTC's Program Finance and Administration Committee members.

The New York City (NYC) metropolitan region is home to close to 20 million residents, more than 600,000 business establishments, more than 1.3 million registered trucks, and more than 8.8 million employees. Every year, more than 80 million trucks cross the toll facilities administered by the various transportation agencies (New York Metropolitan Transportation Council, 2004). This traffic translates into a total amount of cargo of about 200 million tons. The bulk of these goods accounts for 79% of the region’s goods while the national average is 44%.

Project Objective:

• Provide information about containers (status, location, etc.).
• Facilitate communication between parties (motor carriers, ocean carriers, leasing companies, chassis pool operators), with a view to matching their needs.
• Permit equipment interchange and other processes to take place without moving the container to the marine terminal.
• Assist the parties to make optimal decisions regarding container logistics (return, reuse, interchange, etc.), rationalize moves, and plan ahead.

Project Abstract:

Project Objective

Quality assurance is an important component of concrete construction. In most cases the quality of concrete is assessed using 28 day companion cylinder strengths Because corrections cannot be done economically after 28 days, the quality of concrete is always monitored at earlier stages. The most widely used quality control measure of plastic concrete is slump. The other measures are air content and wet density.

A variety of techniques have been proposed for modifying travel behavior to yield better environmental solutions. One strategy that is receiving increased attention focuses on altering land use patterns. Kenworthy and Newman's "Gasoline Consumption and Cities" (1989) emphasizes the benefits of traditional, compact cities with mixed land use and clustered housing. The authors report a negative correlation between population density and gasoline consumption.

Project Objective

The project's main focus is to analyze users' behavioral changes as a consequence of the implementation of value pricing by the Port Authority of New York and New Jersey (PANYNJ).

This project evaluated New Jersey Department of Transportation’s three year fixed schedule re-striping program to see if it is consistent with the actual service life of the pavement markings. One of the primary tasks was to develop a threshold value of retroreflectivity below which a pavement marking will no longer be considered “bright enough” to be useful for motorist nighttime guidance.
