The City of Winnipeg Linear Referencing System (LRS) is a new road network view that can enable users to:
- Use the network as a backdrop for other featured data
- Visualize streets in regard to classification (Arterial, Collector, Local)
- Build a road network with edge, node and turn queries for routing analysis
- Perform Network Coverage analysis. This type of analysis finds all paths that can be traversed from a set of origin stops within a given user cost or distance. This is useful for planning what locations can be reached in a given time from a given location(s)
- Find the closest N destination stops to a set of origin stops
- Find the best path for a vehicle that needs to make one or more stops
- Navigate from one address to another using the included address ranges
Things to be aware of when using the Winnipeg LRS:
- Although attempts have been made to ensure the geometry and attribute data is correct, errors still exist in the network. Please use at your own risk.
- The LRS segments have been digitized in the direction of the municipal addressing
- One-way values are as follows:
0 – The street is a two-way street
1 – The one-way direction is opposite the digitized direction
2 – The one-way direction is the same as the digitized direction
With regard to speed limit data:
- The City of Winnipeg is a “restricted speed area” and all roadways within the City limits have a speed limit of 50 km/h unless a different speed limit has been designated under Speed Limit By-law No. 63/2019 (
http://clkapps.winnipeg.ca/DMIS/docext/ViewDoc.asp?DocumentTypeId=1&DocId=7564) or Reduced Speed School Zone By-law No. 76/2014 (
http://clkapps.winnipeg.ca/DMIS/Documents/DocExt/BL/2014/2014.76.pdf)
- This dataset provides a representation of speed limits with the following limitations:
1) Transition points between speed limits are often set at the nearest intersection and may not reflect the exact point described in Speed Limit By-law No. 63/2019
2) Reduced speed school zones (30 km/h) are not included in the dataset.
3) Some “Non-City” roadways (e.g., Perimeter Highway) in the immediate vicinity of the City are included to provide network continuity. The accuracy of these roadways is not guaranteed as they are not maintained by the City of Winnipeg. These roadways have all been assigned a default speed limit value of 99 km/h, however this is not intended to be an actual representation of the speed limit.
4) Transition points between roadways under the authority of the City of Winnipeg and roadways that are “Non-City” (e.g., under the authority of the Province of Manitoba) may not reflect the exact transition point of designated traffic authority.
