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…

The objective of this study was to address the NJDOT need in developing appropriate guidelines for lane charges that would minimize the closure of traffic lanes. The developed guidelines considered the impact on traffic and road users, depending…

Several issues are discussed in the literature that generally affect the termination of an infrastructure contract and the transfer of project ownership to the government agency. These issues include project construction claims, dispute…

This study has identified the general causes of numerous issues that slow or prevent project closeout and recommends actions that address these causes. With a flow diagram of a generic procedure for public closeout as a point of departure, NYSDOT…

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. The estimation of OD matrices can be done by: (a) direct…

This report explains how to estimate freight demand using secondary source of data such as traffic counts. Freight origin-destination (OD) matrices are one of the most important data elements a planner could have, which is why a significant…

Economists have long advocated comprehensive roadway pricing in the form of user charges as the most efficient way to allocate scarce roadway capacity among competing travel demands.1 Actual transport policy, however, lags far behind theories of…
