Data tracking historical truck travel speeds from the road network performance project. The travel speeds, Travel Time Index (TTI), Delay Index (DI) and Buffer Time Index (BTI) were calculated with GPS data collected by GPS fleet tracking units. This data is used by the Ministry of Transportation to monitor truck speed and performance on major roadways within Ontario. *[GPS]: Global Positioning System

Pavement condition data is collected annually using an Automatic Road Analyzer (ARAN). Based on the automated data, the condition of the pavement is evaluated in terms of distresses (Distress Manifestation Index, DMI), wheel track rutting (in mm) and roughness (International Roughness Index, IRI). These indices are integrated into one Pavement Condition Index (PCI) for overall pavement condition reporting and analysis.

This data provides core information on truck travel and commodity flows on the provincial highway network and other significant truck corridors. It includes the basic commercial vehicle information data set. This data is used by MTO's Systems Analysis and Forecasting Office to monitor truck volumes,value of goods and performance on major roadways within Ontario. *[MTO]: Ministry of Transportation
