Abstract
The effect of roadway intersection design is strictly linked to a reduction in traffic congestion, fuel consumption and emissions in an urban area. This paper presents a comparative result of the typical four-legged intersection and roundabout operational performance for effective management. Accordingly, a computer model for estimation traffic emissions for two kinds of intersections is created. This study presents a detailed analysis and modelling traffic flow emissions using PTV vissim software and methodology with reasonable solutions to plan a road intersection.
Highlights
Global CO2 emissions are one of the fastest growing sectors in the world in passenger and freight transportation
We first analyze the traffic emissions based on traffic data, such as vehicle count and composition
Two intersection alternatives were proposed for the calculation of traffic emissions and operational performance
Summary
Global CO2 emissions are one of the fastest growing sectors in the world in passenger and freight transportation. The share of transport emission is likely to increase carbon dioxide levels again, due to dependence on fossil fuel and the growing demand for mobility and freight transportations. Environment protection is one of the critical human problems since its solution affects people's lives, health, and welfare. Automobile transport is one of the main polluters of the environment. The harmful gas elements emitted into the atmosphere in the process of the engine operation there are more harmful to human health (carbon dioxide (CO2), carbon monoxide (CO), particulate matter (PM), nitrogen oxide (NOx) and volatile organic compounds (VOC)). The importance of the problem is more critical in the city, where the density of the automobile is high, which has contributed significantly to the number of traffic emissions
