Economic Evaluations for Infrastructure Works


Economic valuations perform two important functions; selecting the economically preferred option for any individual project, and comparing the relative economic merits of different transportation activities. These can range from road maintenance, road and bridge construction, walking and cycling facilities, intersection improvements, safety improvements, public transport, freight services and many more. It is important that transportation funds are used most effectively and that you can demonstrate why a project qualifies for roading subsidy.  

The course is based on the NZ Transport Agency’s Economic Evaluation Manual. It focuses on the basic principles, and provides practical exercises on some of the more commonly used procedures. 

If you are in a role where you or your team needs to decide the best solution for a transportation project or need to provide economic justification for a roading subsidy, then this course will help you understand the basic requirements.
