Usage Guidance
-
This metric is intended to capture the length of road (urban or non-urban) that was newly built or improved during the reporting period. Improvements to roads can include repaving, adding lanes for cars, or adding access for bikes and other non-motorized transport, among other improvements.
-
This metric is often used by International Finance Institutions (IFIs) as part of transportation analysis. HIPSO (Harmonized Indicators for Private Sector Operations) users should disaggregate from this metric the length of road that increases access to the network for non-motorized forms of transport.
-
Organizations should only report the length of road for which construction has already been completed, not that financed and still under construction.
