## 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

GO Transit is the regional public transit service for the Greater Toronto and Hamilton Area. For more information regarding GO stations and TTC hubs, please visit [Metrolinx](https://www.metrolinx.com/en). GO Stations and TTC lots can also be viewed on a map, by visiting [Ontario 511](https://511on.ca), and can be found under the "hubs" layer.

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.

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

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.

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

Used within the Travellers Road Information Portal Interactive Map to convey transportation related information in both official languages. Camera images are available in real time on certain highways within Central, Eastern & West Ontario. 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 data set is now available via the Ontario 511 Developer API at *[KML]: Keyhole Markup Language

The Ministry of Transportation's Remote Northern Transportation Office in Thunder Bay operates 29 airports. These are located in Ontario's far north, extending from the Manitoba border on the west to Hudson's Bay on the north and to the Quebec border on the east. Except for Pickle Lake and Armstrong, these airports serve aboriginal communities, which have no all-weather road access to the rest of 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 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.
