Passbymätningar

Passbymätningar is a traffic survey method used to collect data on vehicle traffic. The method involves counting the number of vehicles passing a given point over a specific period of time. This is typically done on a highway or a road where the volume of traffic is high.

The process involves setting up a counter or a camera at a designated point on the road, which is usually at or near a bridge or a tunnel. The counter is programmed to record the number of vehicles passing the point, either by counting the individual vehicles or by using automatic number plate recognition (ANPR) technology.

Passbymätningar is often used to gather data on traffic volume, speed, and composition. The data collected is used to inform traffic management decisions, such as optimizing traffic signal timings, allocating road capacity, and planning new infrastructure projects. The data is also used to identify trends and patterns in traffic behavior.

Passbymätningar has several advantages, including the ability to provide accurate and reliable data, even in high-traffic environments. It is also relatively inexpensive compared to other traffic survey methods, such as license plate recognition and video surveys. However, the method requires careful calibration and maintenance to ensure accurate results.

In some countries, including Sweden, passbymätningar is used as a complement to other traffic survey methods, such as video surveys and mobile data collection. The data collected through passbymätningar is used to validate and calibrate the results from other methods, providing more accurate and comprehensive insights into traffic behavior.
