Operational Street Pollution Model (OSPM)--a review of performed application and validation studies, and future prospects.
Evaluation of the street pollution model OSPM for measurements at 12 streets stations using a newly developed and freely available evaluation tool.
The OSPM are hydrostatic steering units that can be used as a stand-alone product, or packaged with an add-on Sauer-Danfoss' OTPM steering column.
The OTPM steering columns are supplied as an add-on component to the OSPM steering units.
The OSPM line is the small or "mini" portion of Sauer-Danfoss' over-a11 OSP steering unit product range which can be used in off-highway equipment as large as 100 tons with steering system flows to 106 gpm.
In operation, the OSPM consists of a rotary valve and rotary meter.
The OSPM units are available in two versions: an open center nonreaction version; and a power beyond version where surplus oil can be directed to the working hydraulics.
Evaluation and application of OSPM for traffic pollution assessment for a large number of street locations.

2009a), and built a database of emission factors for the Danish car fleet, with data on light- and heavy-duty vehicles back to 1960, which was entered into the emission module of the OSPM. We collected traffic data for the mid-1990s to coincide with the period of enrollment into the cohort and extrapolated forward and backward in time based on knowledge of historical traffic trends for different types of streets.
