Investment performance measurement: Selecting Measures

 

Introduction

This section shows how to select measures in the Business Case Approach.

 

 

Selecting measures

A lot of the discussion and agreement around performance measures for the expected investment benefits will happen in the Strategic Case phase of the Business Case Approach:

 
 

 

In the early stages of the business case, the expected investment benefits can sometimes be very high level. As the business case progresses, they will become more specific. Measures reflecting the expected transport benefits can then be developed, either using the pre-defined measures or by developing local measures based on the framework.

 

Here is a worked example:

Step

Example

Identify the high level benefit from the benefit map.

The benefit is “Greater economic return to the city”.

Work out how transport will contribute to the benefit.

Transport will contribute to this benefit through doing something about “network performance & capability”.

Take the problem that was identified in the investment logic map.

The problem is “The increasing number of private vehicles is creating increasing levels of congestion congestion is where the volume to capacity ratio exceeds 80% for 5 days per week over at least a 1 hour time period that affects at least 1.5 km of a route.  For information on the volume to capacity ratio, see Appendix A3 of the NZTA's Economic Evaluation Manual across the city”.

Identify what investment benefit the problem is about, and select (or develop) appropriate performance measures.

Congestion is about “journey times”, and we can demonstrate the performance of the investment through the measure “travel time” and “travel time delay”.
