What is a traffic count?
A traffic count shows a count of the vehicles, cyclists and pedestrians that pass through a selected street or street intersection usually over a six-hour or a 24-hour period. There are different methods used to collect the traffic count.
What is a speed study?
A speed study is a study that measures individual speeds of vehicles passing a selected street or street intersection in a community over a period of time. This information is useful for monitoring speed trends in a community.
What does the data mean?
Traffic counts and speed studies are a snapshot in time used by professionals to understand the transportation network in the City. Individual traffic counts and speed studies can be influenced by many factors such as weather and time of year the count or study was completed.
This web tool only contains the transportation data and not the analysis for the data. Therefore, the person using traffic counts or speed study information should analyze and interpret the data by applying best practices in the transportation industry, then evaluate the results.
How does The City collect the data?
The City collects the data using manual count and automatic collection methods.
Manual counts are used when data collectors go out to the roadways between April to October and observe and record data. These counts are typically limited to six-hour blocks (consisting of two hour shifts in the morning, midday, and afternoon).
Automatic data collection can be completed in three different ways. The most common way is by placing hoses across the road which detect vehicle movements as vehicles drive over the tubes. Sometimes, video data is collected along roadways by video cameras that are set up on the streets. Also, permanent count stations are embedded in the roadway to collect data. Automatic data is typically collected for 24 hours, but may also be collected for six hours, 12 hours, or for multiple days.
Why does The City collect transportation data?
The City collects transportation data for municipal purposes such as for annual transportation monitoring programs like the Central Business District Cordon Count. This data helps The City to understand changes in vehicles, pedestrians, and bicycles travelling on the roadways in Calgary. The data is also used to help The City make decisions on how to enhance Calgary’s transportation system and to monitor the goals set out in the Calgary Transportation Plan (CTP).
