4. The RDI can be measured separately for motorized and non-motorized travel, taking into account non-motorized shortcuts, such as paths that connect cul-de-sacs, and barriers such as highways and streets that lack sidewalks.
5. The RDI is calculated by dividing direct travel distances by actual travel distances. For example, if streets are connected, have good sidewalks, and blocks are relatively small, people can travel nearly directly to destinations, resulting in a high index. If the street network has many unconnected dead-ends and blocks are large, people must travel farther to reach destinations, resulting in a low index.

30. Sila’a Base Street And Plot Map Converted to GIS for RDI analysis RDI is calculated by dividing direct (“crow flight”) travel distances by actual travel distances on a scale of 0.1 – 1.0. Streets that are well connected are patterned in small blocks, and have good sidewalks - where people can travel nearly directly to destinations thereby resulting in a higher index value. Street networks with many unconnected dead-ends and large blocks – where people must travel farther to reach destinations thereby resulting in a lower index value. An RDI of 1.0 is the best possible rating, indicating that pedestrians can walk directly to all destinations. An average RDI value of 0.65* is considered acceptable RDI DesktopTM Metric Parcel Parcel
