Study On Carbon Emissions And Energy Consumption Of Operational Facilities For Freeway

With the rapid development of modern industry, the demand and use of the world’s oil, coal, natural gas and other chemical energy increase every year, and China is no exception. However, the attendant problem is that the energy generated a lot of carbon dioxide and harmful gas consumed in the process, and cause serious harm to human health and the environment. In China, the transportation industry is a major energy consuming industries, along with a lot of road construction in recent years. Chinese freeway mileage is also increasing year by year upward trend in carbon emissions caused widespread concern. In this context, the study of factors affecting freeway carbon emissions and energy consumption operational facilities along with a very important significance.This article will divide carbon freeway study into two main parts: First, freeway vehicle carbon emissions; the second is the facility energy consumption along the freeway. Firstly, through the investigation and test measurement, respectively the relationship between vehicle CO2 emissions proportional and speed, and between fuel consumption and vehicle speed. Through the analysis of main component of automobile exhaust and their damage, meanwhile considering economic and vehicle traveling economy, originality propose the concept and calculation methods of optimal vehicle speed range of carbon emissions, and use existing data fitting, processing, computing, and ultimately determining the interval values. Then analyze the factors that affecting vehicle carbon emissions one by one, getting the impact pathways and the degree of influence. Combining variety of factors and the optimal vehicle speed range, can provide the basis for low-carbon vehicles on the freeway, and reduce carbon emissions. For the main operational facilities such as freeway tunnels, service areas and toll stations, through analyzing their energy components and the main statistical items, depending on the energy consumption characteristics of the device, propose appropriate energy saving measures and respectively analysis of their energy components. On this basis, advocate the use of solar energy facilities, wind and other new clean energy along the freeway, reducing the consumption of energy from the fundamental and building a low-carbon green freeway operating environment. Finally, take Fuji expressway in Jiangxi province as an example, and according to the survey data analyze the energy consumption of its operating facilities, putting forward the improvement measures and suggestions of low carbon.
