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 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.

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

## General guidelines 1. The dataset contains trip origin, destination, commodity group, average daily trips, commodity weight and value. 2. The data represents activity by medium and heavy trucks only. 3. The origin and destination data is aggregated by counties in Ontario and province or state outside of Ontario. 4. The commodities are grouped into 32 groups and empty trucks. 5. The Commercial Vehicle Survey targets travel on provincial facilities. Therefore, coverage of intra-urban trips is incomplete, and should not be interpreted as representative. 6. Trip activity within the Greater Toronto Area municipalities is not representative. 7. The average trip distance is 440 km. Caution must be exercised with short distance trip activities. 8. All Origin-destination pairs with average trip activity of less than one trip per day have been suppressed. ## Field descriptions **Origin zone** : Trip Origin Zone Number - Zone aggregation is counties in Ontario and province/state for others 35XX - Ontario counties 70XX - U.S. States XX00-XX00 (except 3500) - Canadian Provinces **Origin name** : Trip Origin Name - county or province/state name **Destination zone** : Trip Destination Zone Number - Zone aggregation is counties in Ontario and province/state for others. Same numbering system as origins **Destination name** : Trip Destination Name - county or province/state name **Commodity group code** : Unique commodity group numeric code **Commodity group:** Descriptive name of the commodity group **Daily trips** : Average daily truck trips **Commodity weight** : Average daily commodity weight in kilograms (KG) **Commodity value** : Average daily value of the commodity in dollars ($) *[km]: kilometre

This data, also known as the Linear Highway Referencing System (LHRS), is used to locate events along the highway network. Three separate files make up the LHRS dataset: LHRS route is a spatial (GIS) representation of the highway network; LHRS Base Points divide the highway network into base sections with known driven distances; LHRS features points (composite listing) are additional described locations along the highway network. The location of events can be identified by a driven distance, along the LHRS route from a given LHRS Base point or feature point. *[GIS]: Geographic Information System *[LHRS]: Linear Highway Referencing System

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

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.

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.
