| Summary: | Simple linear distances between origin
and destination poorly describe travel in Nepal, where
rugged terrain, underdeveloped transportation
infrastructure, and diverse vegetation heavily influence
favorable travel routes. In this context, expected travel
times explain more about the remoteness of starting
locations than geographic distance. Applied to service
facilities, these time‐based measures of remoteness amount
to measures of physical accessibility to services. However,
traditional survey‐based measures of time suffer from
problems of inaccurate reporting and standard survey error.
Instead, this study built a geographic information
system–based cost time model of travel that enables more
accurate and generalizable assessment of accessibility.
Having validated the generic model and compared it with
other popular metrics, the study demonstrates its value by
inputting a variety of services into it. This paper provides
descriptive analyses of accessibility trends to these
services at national, provincial, municipal, and geographic
scales and suggests research possibilities unlocked by such
a general purpose model. The paper concludes with thoughts
for how the data and analysis, both freely available public
goods, can enable additional research and better policy making. |
