Transportation Data products and services

The Transportation Data Team collects, analyzes and distributes a variety of data and provides a range of services. The major Services and Products are listed below.

Transportation Data Collection Program

Traffic volume flow map (AAWT Map)

The traffic volume flow map illustrates the Average Annual Weekday Traffic (AAWT).

Copies of historic traffic volume flow maps can be downloaded (PDF).

Intersection Turning Movement Count (TMC)

An intersection Turning Movement Count (TMC) is a manual count of the intersection generally conducted over a 6 to 8-hour period by a Data Collector. They record the number of vehicles entering each approach of the intersection, as well as the specific turning movement completed by each vehicle (left turn, right turn and through). Pedestrian, bicycle and truck data are also collected.

Traffic Volume, Classification, and Speed studies

Traffic Volume, Classification and Speed studies are collected using electronic data collection equipment and road tubes for 24-hour periods.

Reports and statistics are available by direction or for the total on the roadway.

Data from these reports are also used to derive conversion factors for adjusting Intersection Turning Movement Counts from 6-hour to 24-hour traffic volumes.

Permanent traffic monitoring station

The City operates a number of permanent traffic monitoring stations, which collect traffic volumes 365 days of the year. The newer stations also collect speed and vehicle classifications.

In addition to providing daily traffic volumes the data from the permanent stations are used to develop conversion factors for daily and seasonal variation for adjusting manual traffic counts. Data is also used to monitor trends, for the traffic volume flow map and system performance.

Monitoring and Reporting Program

The Mobility Monitor, Commuting Dashboards and Core Indicators for Land Use and Mobility are publications used to report strategic trends and events that affect the implementation of the Calgary Transportation Plan (CTP) and Municipal Development Plan (MDP).​​
