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

This date set contains up-to date information regarding current and future roadwork occuring on provicnally owned and maintained highways, and is available to be viewed on [Ontario 511](https://511on.ca) under the "construction and roadwork" layer. This data set can also be viewed on the Ontario 511 text report page at https://511on.ca/list/roadwork.

This data set contains up-to date information regarding ongoing construction projects on provincially owned and maintained highways, and is available to be viewed on [Ontario 511](https://511on.ca) under the "construction and roadwork" layer.

Used within the Travellers Road Information Portal Interactive Map to convey transportation related information in both official languages. Contains a list of the 23 service centres managed by the Ministry of Transportation along Highway 401 from Windsor to the Quebec border, and along a portion of Highway 400 north of Toronto. This data is best viewed using Google Earth or similar Keyhole Markup Language (KML) compatible software. For instructions on how to use Google Earth, read the [Google Earth tutorial](http://www.google.com/earth/index.html) **.** This dataset is now available via the [Ontario 511 Developer API](https://511on.ca/developers/doc) *[KML]: Keyhole Markup Language

The Ontario Dam Inventory (ODI) is an inventory of medium and large dams throughout Ontario. It uses a point-based system (x, y location) to identify each dam location. The ODI does not contain: * small dams * small water control structures * beaver dams * water crossings * road embankments * locks * falls * rapids * culverts Each dam location has an identifier that can be used to link to other dam information databases.

All bridges in Ontario are inspected every 2 years using the Ontario Structure Inspection Manual (OSIM) format. The weighted condition of all elements is summarized in the Bridge Condition Index (BCI). More details about the BCI can be found on [the Bridge Safety page](http://www.mto.gov.on.ca/english/highway-bridges/ontario-bridges.shtml) on the Ministry of Transportation website. Bridges that were recently constructed or recently transferred to the Ministry of Transportation may not have been inspected in OSIM format yet. *[OSIM]: Ontario Structure Inspection Manual *[BCI]: Bridge Condition Index

Interchanges are shown on the Official Road Map of Ontario (ORM) as information for the travelling public. This feature class includes all interchanges on provincial highways as well as interchanges on other roads (eg. Municipal, outside of Ontario and US) that are shown on the ORM. *[ORM]: Official Road Map *[eg.]: for example *[US]: United States

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 index identifies project areas on provincial highways where aerial photography and photogrammetric mapping has been collected.

Data collected between 2005 to 2007, 3% of sample collected in 2005, 51% in 2006 and 46% in 2007. This dataset contains a compilation of data collected from different sources. **VOG 06/** **VOG** **08 (Value of Goods)** : The data is derived from the information collected in the 2006 Ontario Commercial Vehicle Survey. This survey is a roadside intercept survey of truck drivers, which collects information about the trip, commodity and the vehicle. The survey primarily captures intercity trucking activity and under-represents truck flows in urban areas. The value of goods provided in this table is derived from the Commercial Vehicle Survey, but factored up to represent the overall trucking activity on the network segment for 2006 and 2008. **AADTT 2006 and ****AADTT** **2008:** The data is derived from the Ministry of Transportation's (MTO) inventory of annual traffic data for the Provincial Highways. The commercial volumes are first calculated using the AADT and the Commercial Percentage values for each traffic segment. These values are then adjusted to remove variations between segments caused by fluctuations in AADT. The volume given for each direction is one-half of the total value. MTO does not maintain volume by direction. For freeway segments with core/collector configuration, the total volume is divided into four equal portions and assigned to each stream. **Hourly Truck Volumes ( WD00-23 and WN00-23): ** These fields contain estimates of average hourly volumes for a typical weekday and weekend day. The estimates are based on observed hourly distribution at more than 100 directional Commercial Vehicle Survey sites across the province, **AADTT** and other information. **RD _NAME:** Name of the road **VOG** **06:** 2006 average daily value of goods assigned to road network link by directions. **VOG** **08:** 2008 average daily value of goods assigned to road network link by directions. **AADTT** **2006:** 2006 Annual Average Daily Truck Traffic; it is the truck volume assigned to road network link by directions. **AADTT** **2008:** 2008 Annual Average Daily Truck Traffic; it is the truck volume assigned to road network link by directions. **WD** **00-23:** 2008 Weekday ( **WD** ) hourly truck volume; 00 - 23 represents starting hour of the day (e.g. 12 represents 12 P.M. - 1 P.M.). **WN** **00-23:** 2008 Weekend ( **WN** ) hourly truck volume; 00 - 23 represents starting hour of the day (e.g. 12 represents 12 P.M. - 1 P.M.). *[ WD]: Week day *[VOG]: Value of Goods *[AADTT]: Annual Average Daily Truck Traffic *[WN]: Week end *[RD]: Road *[WD]: Week day *[MTO]: Ministry of Transportation *[AADT]: Annual Average Daily Traffic
