The thrust of the New Zealand government for the road industry is how to generate considerable savings at the same time achieve satisfactory road efficiency through implementing the following directives:
- flat lining of maintenance funds
- increasing economies of scale for roading authorities
- using different procurement models
In response to this, this paper presents the importance of using optimisation tools in defining long and medium terms maintenance plans.
The “Project Level Decision Making Versus Strategic Investment Analysis” paper has the following objectives:
- Demonstrate why optimised maintenance programmes yield better long-term results on road networks;
- Highlight the limitation of maintenance ranking methods that solely depends on a snapshot of condition data;
- To suggest techniques of better linking long-term strategic investment programmes with short-term maintenance programmes.
A section deals with “Optimisation”, its theory, methods and tools for industry applications.
Reading “The Status of dTIMS in New Zealand” would enable you to understand the importance and advantage (for New Zealand) of using the Deighton’s Total Infrastructure Management Software (dTIMS) software in coming up with analysis results and optimised strategic programme.
If you’re looking for best practices in road maintenance planning and ensuring ultimate return on road maintenance expenditure, this paper is highly recommended.
