Development of Quantitative Analysis Methodology on Environmental Effect through Adaptation of Advanced Safety Vehicle
Abstract
The capacity of highway is restricted and traffic congestion is caused by increasing traffic demand. Also, greenhouse gases are increased by traffic congestion. CDM (Clean Development Mechanism) is an idea of interest to reduce greenhouse gases. However, CDM's cases applied in traffic field are rare. Thus, it is necessary that methodology to reduce greenhouse gas should be developed and applied to CDM. A methodology for identifying greenhouse gas emissions was developed in this paper. This methodology was developed on the basis of baseline methodology registered at UN. Travel time and speed in the conventional traffic condition and in the automated traffic condition are compared by BPR function. The calculated speed applied to emission factor equation and then CO2 emissions was calculated. A simulation was executed to evaluate the validity of the developed methodology. In the result, advanced vehicle's CO2 emissions are more than conventional vehicle's CO2 emissions in the stable flow condition. However, advanced vehicle's CO2 emissions are less than conventional vehicle's CO2 emissions in the unstable flow condition. It is assure that capacity of highway is enhanced and efficiency of highway is improved by adopting advanced safety vehicle in the smart road.
