Systems dynamics modelling of pollution emission by road transport sector in Bangladesh

Abstract

Emissions from road transport vehicles in Bangladesh have been modelled here. Systems dynamics approach is considered to simulate the developed model. In order i to achieve this, causal relationships are established amongst the varioUs interacting variables and are put into causal loops. Dynamics feedback loops are constructed from this causal loop diagrams and corresponding equations are developed for Professional DYNAMO Plus systems simulation software. Models thus developed are run with the data collected from national and international sources. Results obtained from these models give us a clearer picture of the future ermissions from road vehicles in Bangladesh. Sensitivity analyses are carried out on the major variables like number of vehicles, fuel consumption etc.
