The Triborough Bridge and Tunnel Authority (TBTA) operates seven bridges and two tunnels in New York City, all of which charge tolls. The TBTA is contemplating increasing tolls in early 1993. This study had two purposes related to the potential increase. The first purpose was to determine the impact of the toll increase on traffic volumes and revenue. The second purpose of the study was to determine the impact on revenue of creating a new toll class. Currently the TBTA has nine classes of vehicles that pay differing tolls.

Project Objective

The goal of this study is to develop a research plan that will enable the interested NYSDOT staff to get a full understanding of modeling tools. This kind of expertise can be obtained by understanding

General Discussion

Accurate transportation emissions inventories are a key component to transportation planning, air quality modeling, and relevant policy making. Regional level inventories are essential to the conformity process required by the Clean Air Act, and they can help inform planners of the regional effects of changes to the transportation infrastructure. Regional inventories alone provide an incomplete picture, however.

The nighttime driving environment, consisting of roadway illumination, signs, vehicle lighting and markers, delineation and signal lights, can be complex or even confusing for both pedestrians and drivers. The nighttime construction environment is even more complex and even chaotic because of the added presence of workers, bright lights, flashing signals and many potential hazards not usually found along the nighttime roadway environment.

Project Description

This study will suggest approaches to address the impacts of these events; simultaneously it will capture recent economic history to note advantages and disadvantages of specific locations and corridors with the State of New York, within regional states, and the new, Global (International) corridors. For New York to sustain its global economic advantages it must build on its strengths, and its unparalleled location advantages.

In the United States and Canada, park and ride (P&R) facilities have existed in one form or the other since mid-1920s. More recent public investment in P&R facilities is mainly a response to increasing global oil prices and an initiative by DOTs to provide alternative transportation services (facilitate the use of mass transit systems in particular). With the emergence of new technologies, innovative public-private partnerships and the need for ‘green transportation’, the role of P&R facilities is rapidly changing.

Project Objectives

1. To describe, quantify and assess the nature and impact of current and proposed transportation infrastructure investments upon accessibility and economic development.
2. To review and quantify recent and proposed land use changes and developments, and evaluate such changes as a response to investment and accessibility.

Project Description

The proposed study would use an epidemiological approach to examine possible predictors of and current interventions for safety in aviation, highway and marine modes of transportation in two regions with widely different safety records: New York (NY) representing several regions in the US, and Tanzania (Tz), representing several regions in Africa (see diagram). For most transportation modes, NY has one of the best and Tz has among the worst safety records.
