Abstract:
Implementing sustainable transportation policies is crucial for countries in worldwide to address environmental concerns and meet global targets. In Sri Lanka, the lack of a clear transportation policy has resulted in the absence of any goals for fuel and vehicle pricing, hindering progress towards a sustainable transportation system. To address this issue, a System Dynamics (SD) approach was used to develop a Causal Loop Diagram (CLD) to visually represent the interdependence and interactions of variables in the transportation system, including socio-economic factors, environmental factors, fuel and vehicle factors, and government policies. The CLD identified five loop behaviours: three balancing and two reinforcing loops. The results showed that SD could be used as a reliable tool to guide policymaking in the transportation sector, including fiscal instruments, consumer information, and regulatory measurements for fuel and vehicle pricing.
