A Quick Explanation

The GEOCOUNTS® File Format (1.27) is designed for counting moving objects and is ideally suited to the travel monitoring industry. Here is a list of systems that support this format

It is based on plain text and contains a Header section, which explains how to interpret the count data, and a Body section, which holds time-stamped count data. The Body section can contain records for: a Tally (count taken over a common time period); an Observation (details of an object being counted, such as a vehicle), and; a Monitoring Event (events affecting the count).

The Tally and Observation records also contain a channel ID field. This is used to relate records to a channel definition (SC) header record. Stations and channels of data are explained further in About The Station

A Very Simple File of Traffic Counts

Although there are many types of header records, you only need to include a few to make a valid count file. Here are four hourly tallies from one channel:

This example includes a few more details such as a type classification system, observation records, and a GPS coordinate.
