Road Intersection Improvement – Main Step for Emission Reduction and Fuel Economy

Abstract

Abstract This article demonstrates the changes made in the intersection model using PTV Vissim have an impact on reducing an amount of GHG and fuel consumption. One of the most problematic intersections in Namangan, Uzbekistan, was selected and traffic flow during peak hours was studied in order to prepare the simulation of the intersection. The article offers two types of solution as so to lessen the amount of toxic gases and fuel consumption. In the first solution, the situation was improved by optimizing the phase of the traffic light and by changing the cycle duration. The second solution was to reduce the amount of toxic gases and fuel consumption from vehicles by changing the geometric dimensions of the intersection. After the implementation of both solutions, the current state of LOS was raised from D to A level.
