toll index

The Toll Index is constructed using German MAUT data and was first proposed in IZA DP5522 as a short term leading indicator of the business cycle in Germany. The four measurements make up what we call the Toll Index (TI) and express kilometers (km), trips made (trips) and number of in- and out-bound long vehicles over 12 tons. We scaled our TI measurements to equal the German Production Index on the first date they are jointly available (January 2007 = 103.3).

The data is available at the Data Repository of the IDSC – Research Data Center of IZA. The paper we first studied the properties of these data is published at the Journal of Forecasting.

The Toll Index has been widely covered in national and international press (selection):
