5.5 - Do minimum
Definition
The do minimum for evaluation of transport services is usually considered as a continuation of the present transport networks, service levels and the existing road network in the study area.
The do minimum shall include any costs and resulting demand implications of committed road or service improvements. All committed investment plans that relate to the do minimum during the analysis period must be taken into account. Maintenance, replacement schedules and any planned service changes shall also be included. Improvements are committed if they have been evaluated in accordance with Land Transport NZ's project evaluation procedures and have been approved for funding.
Any investment plans that are not committed shall be included in the evaluation as options.
Any changes to the road system that are committed must be included in the do minimum.
Scope of do minimum
It is extremely important to:
- not overstate the scope of the do minimum
- only include, as part of the do minimum, work which will preserve a minimum acceptable level of service. In some cases, particularly with respect to the road network, the do minimum service level may be less than the existing level of service.
