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

The Ontario Railway Network (ORWN) is seven data classes that use the federal GEOBASE standard for the National Railway Network (NRWN) geospatial data. The seven data classes include: * track * crossing * junctions * marker posts * structure lines * structure points * stations Although the ORWN is mainly used as base data for cartographic products, users will also get railway-associated attributes.

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.

The Cordon Count Data (CCD) includes directional traffic counts at selected sites to understand how vehicles and people move across the region. Traffic data includes the number of vehicles as well as the number of passengers transported by different vehicle types and the transit system. The interval of CCD collection varies 2-3 years across agencies. CCD provides data for three time periods: 13 hours, AM peak periods, and PM peak periods. Summary data are provided for these three time periods for different screen lines, and directions. *[CCD]: Cordon Count Data

This data provides modelled average hourly traffic count information by weekday/weekend. Commercial vehicles and autos data is collected at Commercial Vehicle Survey locations (latitude/longitude) on provincial highways at border crossings. This data is used to model hourly estimates of passenger and commercial traffic volumes across ontario.

This data provides core information on truck travel and commodity flows on the provincial highway network and other significant truck corridors. It provide ESAL information for all provincial highways and other significant truck corridors by road segment. *[ESAL]: Equivalent Single Axle Load

This dataset provides details on the location of MTO aggregate pits. Aggregate pits provide the material necessary to build roadways in the province. Official LIO title: Aggregate Sites MTO *[MTO]: Ministry of Transportation

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

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.
