This project used fundamental heat and mass transfer principles to predict the temperature, water content, and unreacted cement profiles that exist during the first 72 hours of curing in concrete pavements and bridge decks. A two-dimensional model of a bridge deck was developed and model results compared with actual experimental data. Traditional concrete and concrete containing flyash and microsilica additives were considered. Where possible, the information from this program will be used to calculate the thermal stresses in the concrete.

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.

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.

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.

The overall goal of this project is to assess the impact of planned transport infrastructure investment projects on travel behavior and economic development in New Jersey. The proposal for this research project discusses 5 main objectives for this study. The purpose of this working paper is to review these objectives, provide basic definitions, highlight key issues and suggest methodologies to accomplish these objectives. In addition this paper suggests a general structural framework and outlines the main tasks and phases to follow.

The main objectives of this paper are to briefly discuss the alternative modeling frameworks and address some of the key questions in anticipation to the modeling components of the New Jersey's Links to the 21st Century project. This report reviews the spectrum of modeling options seeking to balance the needs of the New Jersey Department of Transportation, the practicality of the different approaches, their conceptual validity, and the corresponding potential for research contributions.

The objective of this project is to perform evaluation tests related to the transmission of
digitized video signals over ISDN lines between a video traffic reporting camera and a
traffic management center. The quality of the received video signals can be used to
effectively monitor existing and developing traffic conditions.
An evaluation plan was developed with the concurrence of NJDOT (sponsor of the
project) consisting of: a) market survey of current video-transmission options, b) the

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.

Just like any other scientific research field, the value of data quality is undisputed in the field of transportation. From policy planning to performance evaluation, from model development to impact studies, good quality data is essential to generate ideas and clear-cut sol u t ions to be implemented by transportation professionals and decision makers.

In this study, we investigated how pedestrian traffic contributes to our State?s
economy, and what benefits walk trips or walk trips linked with other travel modes (e.g.,
cars, transit, bicycles, etc.) have for retail sales within communities located on the State
Highway Touring Route System. In New York State there are more than 180 Central
Business Districts (CBDs) or 'Main Streets' located on the State Highway Touring
Route System [1]. However, there is very little data available on the value of these
