7. Review and improvement of the ATAP Framework and Guidelines

As discussed above, the review and evaluation of the overall collection of policies, strategies, plans, programs and individual initiatives should provide valuable insights into explaining why any differences between actual and desired outcomes are observed, and the contributing factors. These factors may include cost estimates, projected benefits, land use changes, timing of impacts and unintended impacts (positive or negative).

A further consideration is whether some of the differences between actual and desired outcomes are attributable to the underlying methodology in the Transport System Management Framework. To address this possibility, the Guidelines should be independently reviewed at appropriate intervals. Key questions would include:

• Did the Framework prove effective?
• What revisions to the Framework should be made to improve transport planning and assessment?
