Data File Reference
The Berkeley Highway Lab loop detector data collection and processing system operates continuously and generates several gigabytes of data each month. Raw and processed data are stored in text files, and some of the data set is stored in a database. Data is compressed in .sit format and archived on CD or DVD media.
The various data files generated by the BHL loop detector system are described below.
