Exploring the Environmental Modelling of Road Construction Operations Using Discrete-event Simulation

Research Abstract

The practical implementation of sustainable approaches is a challenge for the construction industry. There have been several research efforts to model sustainability. However, current and past modelling approaches have several limitations: they are mainly deterministic, not allowing for the dynamic and changing nature of a live construction site. 

 

This paper explores how a dynamic modelling framework based on discrete-event simulation, which integrates environmental and traffic models, could overcome past difficulties. The modelling framework explicitly incorporates environmental goals in the design of road construction operations in terms of the fugitive and exhaust emissions generated by construction activity and traffic conditions. A hypothetical project is studied to illustrate the use of this framework. The main results show that an optimum number of trucks and front loaders can minimise emission levels. Further research should consider multi-objective analyses involving cost, time and emission levels.
