Counting driveway traffic is a common application for commercial property management and consulting engineers. The type of traffic flow and layout of entrances and exits and the parking lot or roadway itself can make accurate counting a challenge. While one technology will work with one location or application, it may not be suitable for others.

Inductive loop and road tube are the most common sensor types for counting driveway entrance and exit traffic. Because traffic doesn't always flow as freely as possible this can make the location of these sensors a crucial factor in collecting accurate data.
