How this is measured
Traffic: for every freeway sensor in the Inland Empire, the average number of vehicles on a weekday in the month, compared with the same sensor in the same month a year earlier. Only sensors with data in both months count, so new or retired sensors don't look like more or less traffic. Gas: average price of regular gasoline in the Riverside-San Bernardino metro area (Bureau of Labor Statistics). Unemployment: the Riverside-San Bernardino metro area (Bureau of Labor Statistics). Economic data via FRED, Federal Reserve Bank of St. Louis. Road sensors: Caltrans PeMS.
