In this study, we present a methodology for estimating full marginal transportation costs of highway transportation in New Jersey. This methodology is specifically applied to the northern New Jersey highway network. We review the existing studies and identify the highway transportation cost categories. Cost functions are developed using New Jersey-specific data for each cost category. Along with the total cost functions, marginal costs functions are derived. These marginal cost functions are used in the application of our full marginal cost estimation methodology.
A comprehensive guidebook for practical employee commute options (ECO) was compiled for employers in New York State to provide them the technical expertise to develop an ECO program. This ECO guidebook is a result of literature search, employer survey, and the participation of advisory committee members consisting of people from the federal Clean Air Act Amendments of 1990 and representatives of several organizations that have experience working with employers on commuter transportation in the New York metropolitan area. This study identified guaranteed ride home programs, parki
This paper first provides a brief review of trends in public transport demand from 1980 to 2010 in 16 countries inEurope,NorthAmerica, andAustralia.The focus, however, is ona detailed analysis of public transport demand in Germany and the USA, using uniquely comparable national travel surveys from2001/2002 and 2008/2009 for both countries. Public transport has been farmore successful in Germany than in the USA, with much greater growth in overall passenger volumes and trips per capita.
In 1984, 74% of the incoming drivers entering the workforce of the New York City taxi industry were immigrants born outside of the U.S. with the greatest numbers, in ascending order, coming from Haiti, the Dominican Republic, Egypt, Korea, the Soviet Union and Pakistan. In 1988 the survey of students entering the New York City Taxi Driver Institute (NYCTDI) was replicated. It revealed that the immigrant population had increased to 86% with significant numbers still coming from Haiti but with an even higher percentage entering from the countries of the Indian sub-continent.
Bus rapid transit systems have grown in popularity. Most existing and proposed BRT lines operate on city streets for all or a portion of their routes. They may run in mixed traffic; normal or contra-flow curb bus lanes, and/or arterial median busways. This paper describes the design, operations, and effectiveness of each; and identifies the key issues and tradeoffs. Drawing on ongoing research (TCRP Project A-23), it gives illustrative examples of usage, costs and benefits.
The anticipatory route guidance problem (ARG), an extension of the dynamic traffic user-equilibrium problem, consists of providing messages, based on forecasts of traffic conditions, to assist drivers in their path choice decisions. Guidance becomes inconsistent when the forecasts on which it is based are in- validated by drivers' reactions to the provided messages. In this paper, we consider the problem of generating consistent anticipatory guidance that ensures that the messages based on dynamic shortest path criteria do not become self-defeating prophecies.
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 given area, resulting from transportation infrastructure investment, will enhance labor participation, given intervening factors such as socioeconomic and locational characteristics.
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 optimal pricing. In the U.S., the only form of roadway pricing that currently exists is the tolling of a small fraction of the nation's bridges, tunnels, and limited access highways. Most tolled roadways are in the Northeast, and by far the highest concentration is in the New York City region.
