Traffic surveys aim to capture data that accurately reflects the real-world traffic situation in the area. It may be counting the number of vehicles using a road or collecting journey time information for example, but there are many other types of data that traffic surveys collect. In the past this has involved having people standing by the side of roads and recording their observations on paper pads. In recent years, this approach has been largely replaced by recording traffic using video cameras, and then analyzing the video footage later in the office. Even more recently, with faster Internet speeds becoming available, some traffic data collection companies have decided to have their video traffic surveys counted (or enumerated) by companies overseas.
