It is also an objective requirement for advancing the supply-side structural reform of the transportation industry and building a satisfactory transportation for the people. It is also an objective requirement for achieving a beautiful China. The author puts forward some practical experiences of green highway construction through the construction of the typical demonstration project of the Guangji expressway green highway. rivers, and has many air, water and acoustic environment 1 Introduction sensitive points.

  • Green Highway Ratings for Existing NH& SH in Tamilnadu – a Case Study
    ISSN: 0974-2115 www.jchps.com Journal of Chemical and Pharmaceutical Sciences Green highway ratings for existing NH& SH in Tamilnadu – a case study R. Suresh Assistant Professor, Department of Civil Engineering, Vel Tech High Tech Dr. Rangarajan Dr. Sakunthala Engineering College, Chennai, Tamil Nadu *Corresponding author: [email protected] ABSTRACT A Green highway rating system is a proposed standard for quantifying sustainable practices associated with the design and construction of roadways. Various techniques and standards can be incorporated within green highways like natural resources, construction methods, operation & maintenance. Such a standard helps improvement and innovation in roadway sustainability, and provide baseline sustainability standards for planning and designing of highways. An attempt is made to rate the existing National highway (NH) & State highway (SH) in Tamil Nadu using Green highway Rating System (GHRS) to implement the sustainability in highways in the future. Recommendations are then made to improve their performance towards green highways from normal highway. Each infrastructure project, before start of the project must undergo the Environmental Impact Assessment (EIA) process to protect our society in economy, environment and technology. This could improve our social value like reduction in pollution, accident reduction, encourage the number of users and improve the environment life and quality. To reduce the impacts in the future, the green highway rating system and green highway construction guidelines should be followed strictly while during construction, operation& maintenance in all phases throughout the lifetime of the highway. KEY WORDS: Green, standard, existing. 1. INTRODUCTION Green Highway is the essential object to our country growth. Ratings are an important tool to the decision makers.

  • Factors for Implementing Green Highway Concept in Toll Road Development Investment in Indonesia Muhammad Yunus Asy’Ary1,*, Christiono Utomo1
    Advances in Social Science, Education and Humanities Research, volume 474 Proceedings of the 2nd International Seminar on Science and Technology (ISSTEC 2019) Advances in Social Science, Education and Humanities Research, volume 474 Proceedings of the 2nd International Seminar on Science and Technology (ISSTEC 2019) Factors for Implementing Green Highway Concept in Toll Road Development Investment in Indonesia Muhammad Yunus Asy’Ary1,*, Christiono Utomo1 1Department of Management Technology, Institut Teknologi Sepuluh Nopember, Indonesia *Corresponding author: [email protected] ABSTRACT One of the national strategy project programs in Indonesia is the development of toll roads in several regions with a public private partnership scheme by cooperating with toll road business entities (BUJT) as investors and developer. With the existence of global environmental issues, the concept of the green highway must also be applied in the development of toll roads in Indonesia. This research is to find out the factors that apply the green highway concept that is significant to investment decisions on toll road development. This research uses a questionnaire survey method and interviews to obtain data based on the perceptions of the toll road developer in Indonesia. Questionnaire questions consist of several aspects of the concept of green highway based on the green highway rating system in toll road development in Indonesia. Based on the result of the survey, there were twenty categories divided into six aspects consisting of water management and drainage, green materials, sustainable sites, energy emissions and waste reduction, social and economic, life-cycle analysis. Keywords: toll road development, green highway, green rating, investment. Green highway rating system can be interpreted as a tool that is used as a reference in a sustainable concept that 1.

Mark Twain called the late 1800s the “Gilded Age.” Historian Vernon Parrington, however, preferred the more cynical term “The Great Barbecue,” referring to the government’s brutal seizure of the West’s lands and their subsequent giveaway to white settlers, land speculators, and railroad, mining and timber barons. “Congress had rich gifts to bestow — in lands, tariffs, subsidies, favors of all sorts,” wrote Parrington, “and when influential citizens made their wishes known to the reigning statesmen, the sympathetic A bigleaf maple tree in Capitol Forest near Olympia, Washington.

  • Revision of Sustainable Road Rating Systems: Selection of the Best Suited System for Hungarian Road Construction Using TOPSIS Method
    sustainability Article Revision of Sustainable Road Rating Systems: Selection of the Best Suited System for Hungarian Road Construction Using TOPSIS Method Réka Szpotowicz (née Nádasi) * and Csaba Tóth Department of Highway and Roadway Engineering, Budapest University of Technology and Economics, 1111 Budapest, Hungary; [email protected] * Correspondence: [email protected] Received: 28 August 2020; Accepted: 23 October 2020; Published: 26 October 2020 Abstract: There are a number of sustainable and environmentally friendly techniques and methods currently available in the construction industry. To promote sustainable development, different rating and certificating systems that evaluate the level of sustainability during the development of infrastructure construction projects have been developed. The aim of the research presented in this paper was to examine the applicability of sustainability rating systems in Hungary and find the most suitable option. After a review of commonly used rating systems, i.e., Greenroads, GreenLITES, I-LAST, Envision, and INVEST, the most suitable existing rating system is selected with the help of the Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) mathematical decision analysis method. This was achieved by utilizing 12 categories of input data (weights) analyzed through TOPSIS. The input data (weights) of the TOPSIS method were determined by a small research group of industry experts and academic professionals based on Hungarian practices and methodology. As a result of the calculation, the study found that the Envision rating system satisfies the criteria best, closely followed by Greenroads. Keywords: sustainability; Hungarian construction practice; road rating systems; TOPSIS 1. Introduction It is widely agreed that the construction industry has one of the most significant impacts on our environment, contributing significantly to air pollution, resource depletion, waste generation, global warming, and climate change.
