GoodsTransport
Factors affecting movement of goods: (according to Ortúzar, 2011)
- location factors (dependency on source materials)
- chain of dependencies
- physical factors of goods (e.g. steel vs. milk)
- operational factors (e.g. company size and internal regulations)
- geographical factors (e.g. population density)
- dynamic factors (e.g. seasonal changes)
- pricing factors (usually not published like with passenger transport)
- weather
- traffic

MultiModalTransport
Change only at specific locations
Change needs time / is timely constrained
Optimizes for multiple criterions
In contrast to MonoModal / InterModal
Not always the fastest route is best (e.g. pirates)
Legal constraints of certain goods

OSMOSM data types:
- nodes (geographical points + attributes)
- ways (list of nodes + attributes)
- relations (list of nodes or ways + attributes)
5,4% source4,3% building
3,1% highway
Especially streets of higher order areof sufficient quality
Routing with OSM data is alreadydone

Existing Systems
gives examples for multimodal freight transport planning
OpenTripPlanner(personal, integrates multiple sources,uses GTFS as storage format, OSM based)
AnachB(personal, designed for specific region)

FLAVIA(intermodal freight, no real-time traffic)

ferries (water as ways or area, some attributive information)

- monomodal (two ways share a common node, restrictions by relations)
- multimodal (public_transport=platform/station/stop_area(_group), relation)

Route-Planningwith OSM
Building a routable graph is no problem
Many libraries doing routing on OSM exist
- Java: GraphHopper, Brouter, OpenTripPlanner, osmNavigation- C/C++: Gosmore, MoNav, Navit, OpenSourceRoutingMachine, Routino- C#: IMORTIS, OsmSharp, SimpleMapRouting- Scala: osm_routing- Ruby: Mormon- Python: PyrouteLib, SimpleOsmRouter- ClosedSource Solutions...

Additional (real-time)Data with OSM
No real time data in OpenStreetMap
Additional data may be
- too detailed
- updated too often
- be too specific

Missing in OSM
Quality
Frequency
Availability
missing information that cannot be gathered
information that is changing too often
service that is not provided
volume of traffic,storehouse capacity
real-time data on usage
routing algorithm
Type Description Example
Quantity information that is too specific train schedules

Using OSM
OSM is a useable additional source for multimodal transport planning
OSM can not be the only source for multimodal transport planning
MultiModal Routing with OSM Data is already done
When mixing different datasets, thoughts about legal issues are necessary
