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…

ITS is a tool to improve and mange the transportation network effectively to meet growing demands for services. The Transportation Operation Center (TOC) is the heart of the ITS activities. The investment made on technology, infrastructure, and…

This project has developed a state-of-the-art GIS-based interactive tool for calculating network-wide full marginal costs (FMC) of highway transportation in New Jersey. The new tool is used to evaluate the short-term impacts of policy…

Field experience indicates that wick drains installed vertically in grid fashion do not consistently result in the required degree of consolidation, under construction loading, in the time established in design. Such deviations are often related…

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…

In this paper we hypothesize that the local supply of labor (i.e., labor force participation) is affected, among other things, by the level of accessibility to employment locations. Specifically, we conjecture that improved accessibility in a…

Investment in transportation infrastructure is generally regarded as an effective means for inducing economic growth and employment in a region. However, the ability of such investments to achieve these objectives, to a large extent, depends on…

In “The Retrofit Puzzle: Optimal Fleet Owner Behavior in the Context of Diesel Retrofit Incentive Programs” (1) an integer program was developed to model profit-maximizing diesel fleet owner behavior when selecting pollution reduction retrofits.…

This paper reports on a natural experiment which studied groups of commuters who are equivalent in most important demographic respects, and who had equivalent commuting experiences, but were differentially affected by a new and improved mass…

This research critically reviews and analyzes various cost-effective (existing as well as emerging) sensing techniques for use in smart bridge bearings. These sensing technologies were reviewed on the basis of cost-effectiveness, implementability…

The goal of this project has been achieved through three tasks. The main goal of Task I has been to identify appropriate sensors that have potential for bridge bearings applications. This has been achieved through the following subtasks and has…

Public transit system has become one of the targets of terrorist attacks using explosives, examples of which include the 1995 attack on Paris subway and the 2004 attack on Moscow subway.  Under the present context of intense threats of…

In recent years computer simulation has become one of the most widely used and powerful tools in providing synthetic versions of highway traffic. Traffic simulation allows us to understand the current network characteristics, and predict the…

In the last 10 years, New Jersey has invested heavily in its transportation infrastructure, and numerous additional projects are planned or proposed for the next decade. Collectively, these projects have significantly improved accessibility in…

The importance of commuter rail as a transit mode has increased with the expansion of services to new metropolitan areas, such as San Diego, Los Angeles, South Florida, Dallas, and Washington, D.C., and with the expansion of existing services in…

This working paper describes employment trends and patterns in New Jersey over the last decade. Its focus is on the relocation of firms and jobs, into New Jersey, and their transportation implications.

A central component of the New Jersey: Link to the 21st Century project is the calibration of TRANUS, a land use-transportation model, for use in the study of northern New Jersey. The model will be used to forecast the impact of transportation…

An improvement in the transportation system in a certain area will have an impact on accessibility, which in turn may affect land use, economic development and travel patterns in that region. How large is this impact on each of the above…

Performance standards for Integrated Vegetation Management (IVM) can be used to define organizations that manage rights-of-way (ROWs) in environmentally-appropriate, socially-beneficial, and economically-viable manners. Environmentally…

Occupancy of travel lanes during construction and road maintenance are ordinary activities frequently undertaken to maintain the well-being of road infrastructure. When these activities take place, they impact traffic flow and often cause delays…
