Traffic Signal Volume Data - historical

This dataset is the traffic signal volume data. The data is shown as a resource on the main page. The data can be down loaded from here. Each file contains all of the 15 minute traffic volumes for traffic signals by detector for years from 2014. The current year's data is aggregated by month into a zip file. All months for the current year are shown. An automated process loads the data as it becomes available for each month. Only those months up to the current will have data available. A detector is a loop of wire installed into the road surface and is activated when a vehicle passes over it and sends a pulse to the traffic signal.
