Starting from the raw OpenStreetMap data (in the form of the '.osm' XML files available on the internet) a custom database is generated that contains the information useful for routing. With this database and two points specified by latitude and longitude an optimum route (either shortest or quickest) is determined. The route is calculated for OpenStreetMap highways (roads, paths etc) using one of the common forms of transport defined in OpenStreetMap (foot, bicycle, horse, motorcar, motorcycle etc).
When processing the OpenStreetMap data the types of highways are recorded and these set default limits on the types of traffic allowed. More specific information about permissions for different types of transport are also recorded as are maximum speed limits. Further restrictions like one-way streets, weight, height, width and length limits are also included where specified. Additionally a set of properties of each highway are also recorded. The processing of the input file is controlled by a configuration file which determines the information that is used.
When calculating a route the type of transport to be used is taken into account to ensure that the known restrictions are followed. Each of the different highway types can further be allowed or disallowed depending on preferences. For each type of highway a default speed limit is defined (although the actual speed used will be the lowest of the default and any specified in the original data). To make use of the information about restrictions the weight, height, width and length of the transport can also be specified. Further preferences about road properties (e.g. paved or not) can also be selected. The simplest type of turn restrictions (those formed from an initial way, a node and a second way) are also obeyed.
The result of calculating the route can be presented in several different ways. An HTML file can be produced that contains a description of the route to take with instructions for each of the important junctions. The contents of the file are created based on a set of translations specified in a configuration file. The route is also available in a GPX (GPS eXchange) XML format. format file containing either every point and highway segment (a track file) or just a waypoint and translated instructions for the important junctions (a route file). Additionally there are two plain text files that contain all data points or just the important ones (intended for debugging and further processing).
One of the design aims of Routino was to make the software are flexible as possible in selecting routing preferences but also have a sensible set of default values. Another design aim was that finding the optimum route should be very fast and most of the speed increases come from the carefully chosen and optimised data format.
Routino comes with ABSOLUTELY NO WARRANTY for the software itself or the route that is calculated by it.

The full version history is available in the NEWS file.
- Force '<if>...</if>' in tagging rules to match even with no input tags.
Built-in translations for GPX-route file gave nonsense durations.
Handle some cases that potentially caused divide by zero (not crashes).
- All configuration is now contained in the top level file Makefile.conf.
Default to using -ffast-math option for faster maths and glibc workaround.
- Code improvements:
- Improve router internal data structures to increase performance.
Add another layer of caching to significantly speed up slim mode operation.
Add a layer of file buffering to significantly speed up reading/writing.
Enable more compile-time warnings and fix them.
- Create a binary log file to allow searching for errors geographically.
Simplify processing for changes (segment files not kept).
Don't prune isolated regions for transport types we don't have.
- Web pages (visualiser):
- Allow displaying the error logs on the map.
Allow selecting any item displayed and showing more information about it.
- Create a separate directory to put extra (non-essential) programs and scripts.
- tagmodifier - a tagging rule testing program.
- errorlog - a script to summarise the planetsplitter error log.
- plot-time - a script to plot a graph of the planetsplitter execution time.
- find-fixme - search an OSM file for "fixme" tags and display them on a map.
