Routino Introduction
Routino is an application for finding a route between two points using the dataset of topographical information collected by http://www.OpenStreetMap.org.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, motorbike 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 oneway 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 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.
Disclaimer
The route that is calculated by this software is only as good as the input data.Routino comes with ABSOLUTELY NO WARRANTY for the software itself or the route that is calculated by it.
Demonstration
A live demonstration of the router for the UK is available on the internet:http://www.routino.org/uk/
The source code download available below also includes a set of files that can be used to create your own interactive map.
The interactive map is made possible by use of the OpenLayers Javascript library from http://www.openlayers.org/.

Changes in Version 1.5
- Bug fixes:
- Check that number of nodes/segments/ways doesn't exceed numerical limits.
Allow 32-bit systems to seek within files larger than 4GB.
Allow nearly 4G nodes to be stored instead of 2G before.
Added rules to makefile for installation (paths specified in top-level).
Stricter checking of UTF-8 in XML files and better UTF-8 output.
Improve error message if parsing of command line options fail.
Fix bugs in router's --help-profile-json and --help-profile-perl options.
Rename heapsort function to allow compilation on Mac OS with no change.
Reduce impact of property preferences close to 50% by using sqrt(). - Documentation:
- Update documentation to reflect changes in program usage and function.
- OSM tagging
- Traffic restrictions on nodes are now included in default tagging file.
Added processing for ferry routes (as pseudo-highway type 'ferry').
Process foot and bicycle route relations to create new properties. - Configuration Files:
- Added Dutch output translations.
Added ferry information to profiles.
Added foot and bicycle route relation processing. - planetsplitter
- The slim mode now includes the output data as well as the temporary data.
The slim mode is now a separate executable and not a command line option.
Traffic restrictions on nodes are now understood when parsing OSM files.
Falls back to installed tagging.xml configuration file as last resort. - router:
- Added a slim mode (as a separate executable and not a command line option).
Traffic will not be routed through a node that does not allow it.
Falls back to installed profiles.xml & translations.xml files as last resort. - filedumper:
- Added a slim mode (as a separate executable and not a command line option).
- Web pages:
- Added Dutch translation of router.html.
Additional Changes in Version 1.5.1

- Ensure that enough memory is allocated for filenames.
Fix bug that sometimes causes crash when processing route relations. - Documentation:
- Update documentation to reflect changes in program usage and function.
- Programs:
- Add an option to make the output more suitable for a log file.
- Documentation:
- Update documentation to reflect changes in program usage.
