 Description: Tools for transport planning with an emphasis on spatial
-    transport data and non-motorized modes. Create geographic "desire
+    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 accessiblity 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); calculate routes on the transport network locally and via
-    interfaces to routing services such as <https://cyclestreets.net/>;

+    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>.  Further

+    '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
