11. Summary of the new findings of the thesis

- Study overview of road greenery planning in the world and Vietnam;

- Review the current status of greenery planning for some key highways of Red River Delta.

- Analyze and evaluate environmental parameters (soil - water - air) on the National Highway as the basis for selection of suitable plant species to make the scientific basis for the orientation of greenery plan for national highways in the Red River Delta.

- Plan a line of trees on the highway of Red River Delta under the criteria of environmental ecology - traffic safety and economy - society (case study: greenery planning for highway No.2 and Vo Van Kiet street).

12. Practical applicability, if any:

Define the role and importance of trees for transport development, social security and environmental protection on the highways of Red River Delta.

Contribute to the protection and restoration of roads in landscape planning, design, construction and upgrading of highways. Propose environmental scientific basis for research on adjusting some norms in building codes and standards for greenery design of highway RRD line, practical to apply to the development of research, planning evaluation and construction planning and management of trees on the highway route of the Red river Delta in the near future; applications for greenery planning regulations for other highways.

13. Further research directions, if any

Research for more road objects (highway, national highway, provincial highway, urban, ...) in different areas (7 ecoregion, through plains, over mountains, across seas, plateaus, through the flooding, storm surges, ....).

Combine empirical and laboratory methods to select species of trees are more ecological functions and ensure environmental safety requirements of road traffic as well as the beauty of the route.
