Traffic Volumes Data
2004 Onward Traffic Reports: Additional Information
Highway Direction
For simplicity, MoT assumes that highways in British Columbia are either north-south or east-west along their entire route. The major exception to this rule is Route 1, which is primarily east-west; on Vancouver Island, in Vancouver and in the Fraser River Canyon, Route 1's direction changes from east-west to north-south. Exceptions also occur on Route 99 and Route 6.
Descriptions of count site locations are typically stated using direction and distance from a cross road, municipality, bridge or other landmark. The direction of the count locations from these landmarks will be in terms of the predominant direction of the entire highway route and may not reflect the true compass orientation of the highway at that location.
Report Styles
There are many different ways to summarize traffic flows. Listed below are the reports presented in this web site.
- Daily Vehicle Length
- Annual Average Vehicle Speed
- Monthly Average Vehicle Speed
- Annual Average Traffic Volumes
- Annual Average Vehicles by Day of Week
- Monthly Volume Calendar
- Monthly Volumes by Hour
- Monthly Average by Hour and Day of Week
Definitions
Roadway: Traffic Measurements for all traffic using the Highway, as illustrated below.
- Pos1, Pos2, etc: Traffic Measurements for a single Northbound or Eastbound (Positive Direction) lane of the Highway. Pos1 is the rightmost (and slowest) lane, Pos2 is the lane to its left, Pos3 further left, and so on.

- Pos DIR: Traffic Measurements for all Northbound or Eastbound (Positive Direction) lanes of the Highway, as illustrated by Pos DIR below.
- Neg DIR: Traffic Measurements for all Southbound or Westbound (Negative Direction) lanes of the Highway, as illustrated by Neg DIR below.

Future Enhancements
Geoplan Opus Consultants Inc. (Geoplan) is currently under contract to manage TM data using the TRADAS system.
TRADAS, produced by Chaparral Systems Corporation, is used by a number of transportation agencies worldwide to load, validate and store traffic measurement (TM) data, and to perform analyses which produce detailed, summary and statistical TM reports.
The ministry monitors our customer requirements for traffic data and is looking for feedback from all our user groups on the type of traffic data they need. This web site provides a feedback form that will help us identify your requirements; please feel free to let us know what type of traffic data you are interested in acquiring.
The ministry will continue to monitor these UTVS segments to ensure they represent uniform traffic sufficiently. It is expected that these segments will change over time as traffic patterns change and land use and land development create changes in traffic demand.
The ministry is also continuing to upgrade the presentation, distribution and interactivity of applications that disseminate traffic information. As these applications are introduced, the ministry will be making them available over the Internet to our various client groups.
