This is a local decision. The MPO may use additional breakdowns of the NTD-reported asset types, if this is useful to the MTP and TIP planning process and performance reporting. The performance reports should be clear on how all of the MPO’s targets were developed. Please note that 49 CFR 625 requires transit providers to report their SGR targets in terms of NTD’s asset types. See the NTD Asset Inventory Module (AIM) for more information on asset data.
