DEVELOPMENT OF SIMULATION MODEL FOR ESTIMATING GAS EMISSIONS FROM EQUIPMENT IN RAILWAY CONSTRUCTION PROCESSES

Abstract

The railway construction utilizes several pieces of heavy equipment resulting in exhaust
emissions such as pollution and greenhouse gas emissions (GHG). The release of emissions can affect the
environment and human health. Although many previous studies have attempted to approximately estimate the
amount of emissions, they did not consider the detailed processes of construction. The simulation model can
be applied to improve this limitation and provides the ability to allocate resources and optimize the construction
process. In addition, it can help to analyze alternative approaches to reduce emissions. This paper presents the
development of simulation model to analyze the amount of exhaust emissions from the equipment usage in
railway construction. It compares the amount of exhaust emissions from the situation in the railway
construction process, which will demonstrate the effects on the relationship between the amount of exhaust
emissions and the construction approach. As a result, this research provides an alternative method to manage
exhaust emissions from the railway construction process and resource management.
