od2odf

Tools for transport planning with an emphasis on spatial
transport data and non-motorized modes.
The package was originally developed to support the 'Propensity to Cycle Tool', a publicly available strategic cycle network planning tool
(Lovelace et al. 2017) <doi:10.5198/jtlu.2016.862>, but has since been
extended to support public transport routing and accessibility analysis
(Moreno-Monroy et al. 2017) <doi:10.1016/j.jtrangeo.2017.08.012> and
routing with locally hosted routing engines such as 'OSRM'
(Lowans et al. 2023) <doi:10.1016/j.enconman.2023.117337>.
The main functions are for creating and manipulating geographic "desire
lines" from origin-destination (OD) data (building on the 'od'
package); calculating routes on the transport network locally and via
interfaces to routing services such as <https://cyclestreets.net/>
(Desjardins et al. 2021) <doi:10.1007/s11116-021-10197-1>;
and calculating route segment attributes such as bearing. The package
implements the 'travel flow aggregration' method described in Morgan
and Lovelace (2020) <doi:10.1177/2399808320942779> and the
'OD jittering' method described in Lovelace et al. (2022)
<doi:10.32866/001c.33873>.
Further information on the package's aim and scope can be found in the
vignettes and in a paper in the R Journal (Lovelace and Ellison 2018)
<doi:10.32614/RJ-2018-053>, and in a paper outlining the landscape of
open source software for geographic methods in transport planning
(Lovelace, 2021) <doi:10.1007/s10109-020-00342-2>.

od2odf function

<dl><dt>flow</dt>
<dd>A data frame representing origin-destination data.
The first two columns of this data frame should correspond
to the first column of the data in the zones. Thus in <code>cents_sf()</code>,
the first column is geo_code. This corresponds to the first two columns
of <code>flow()</code>.</dd>
<dt>zones</dt>
<dd>A spatial object representing origins (and destinations
if no separate destinations object is provided) of travel.</dd></dl>

Arguments

Extract coordinates from OD data — od2odf

The first two columns of this data frame should correspond
to the first column of the data in the zones. Thus in <code>cents_sf()</code>,
the first column is geo_code. This corresponds to the first two columns
of <code>flow()</code>.</dd>


<dt>zones</dt>
