Developing a Green Route Model for Dry Port Selection in Vietnam

The dry port can smooth the movement of cargo and eliminate capacity pressure, natural restriction and externalities faced by seaports. A network of dry ports also can reduce the amount of pollution emitted from logistics activities by allowing the increasing share of environmentally friendly modes of transport. The paper suggests a green routing model for dry port selection to increases the percentage of using rail or inland waterway transportation in the journey through dry port, instead of road transportation. This model reduces the amount of emission from logistics activities, such as carbon dioxide (CO2), nitric oxides (NOx) and particulate matter (PM) with the minimum cost, considering both the emission charge and the shipping charge. A case study is conducted for Samsung Thai Nguyen factory in the North of Vietnam to validate the model application. The results indicate that the smallest total cost route saves up to 51% of CO2 and 36.5% of PM emission exhausted than unimodal road transportation. The research provides a useful guideline for new green transport policies of public agents as well as decision-making processes in private companies.
