{"title":"Intelligent Transportation Systems Provide Operational Benefits for New York Metropolitan Area Roadways: A Systems Engineering Approach","authors":"Charles R. Berger, Egan Smith","doi":"10.1109/LISAT.2007.4312628","DOIUrl":"https://doi.org/10.1109/LISAT.2007.4312628","url":null,"abstract":"The New York metropolitan area experiences considerable traffic congestion. However, within the New York metropolitan area right of way is limited and building additional roadways to alleviate congestion is no longer an option. Therefore, to alleviate congestion the New York State Department of Transportation (NYSDOT) has sought out congestion management strategies that do not require the construction of new roadway. A major thrust of this strategy is the deployment of Intelligent Transportation Systems (ITS). To facilitate this endeavor Dunn Engineering Associates has developed the Evaluation Model for Freeway ITS Scoping (EMFITS). EMFITS was developed as part of the NYSDOT Intelligent Transportation Systems Scoping Guidance Project Development Manual. This model captures the essence of ITS strategies at the scoping stage of the design process and provides a key guide to the most beneficial ITS strategy to be implemented. EMFITS was used to calculate the quantitative benefits from ITS alternatives to be deployed along approximately 31 miles of interconnecting parkways and expressways in the Eastern Queens roadway network. The specific roadways include: Long Island, Clearview and Nassau Expressways; Grand Central, Cross Island and Belt Parkways. Typical transportation planning processes often do not easily accommodate transportation system improvements that have a systems-operation focus such as ITS. However, state and local agencies still need to answer the basic questions of costs and benefits before any ITS project will be implemented. EMFITS deployment and performance evaluation methodologies can assist ITS managers in determining the most cost effective systems. EMFITS can guide the growth of ITS in a more organized manner by providing transportation decision makers with quantitative measures of effectiveness such as reduction in vehicle-hours per year, gallons of fuel per year, hydrocarbons, carbon monoxide, oxides of nitrogen, accident, agency operating cost, and ton-hours (freight measure of delay) that can be used to determine the financial benefits of different levels of ITS deployment. Determining financial benefits is critical for any successful state or local ITS program. This paper presents a variety of tools, techniques, and guidelines to develop reasonably comparable answers to these questions applied to the deployment of ITS along the Eastern Queens roadway corridors.","PeriodicalId":287484,"journal":{"name":"Long Island Systems, Applications and Technology Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126122908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Economic Analysis of Renewable Energy Systems","authors":"H. Tawfik, Charles P. Rubenstein, Noel Blackman, Davinder Mahajan","doi":"10.1109/LISAT.2006.4302663","DOIUrl":"https://doi.org/10.1109/LISAT.2006.4302663","url":null,"abstract":"As the price of oil and natural gas continues to increase, reaching levels that threaten our local and national economy, the need to seek alternative sources of energy has become necessary to reduce our dependence on foreign oil and enhance homeland security. The USA has an abundance of renewable energies such as solar, wind, hydro and bio-fuels that need to be explored for generating hydrogen as an energy carrier. Engineering and Technology graduates must be well educated and highly trained with use and applications of the alternative energy systems. Accordingly, students should be instructed on the state of the art technology and modern systems in this area of increasing national interest. Renewable Energy sources will reduce our national dependence on foreign oil and enhance our homeland security because of their environmental and economical merits. This paper introduces engineers, technologists, and students interested in the area of renewable energy systems to the utilization of a modern software product that will enable them to conduct both technical and economical analysis on alternative energy systems. Software products from RETScreen International provide the user with clean energy decision capabilities. It enhances the capacity of planners and decision-makers by presenting them with a tool to implement renewable energy and energy efficiency projects in alternative energy systems such as solar, wind, and hydro.. The software (free download available at www.retscreen.net) enables economic analysis and parametric studies on a variety of renewable energy systems.","PeriodicalId":287484,"journal":{"name":"Long Island Systems, Applications and Technology Conference","volume":"1988 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134630176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
