Automotive data is an important economic parameter that is tracked by both private organizations and governments across the globe. Both the quantity and type of automotive data available in Wolfram|Alpha were recently expanded to include the amount of traffic, vehicles in use, auto-related injuries and fatalities, and road lengths by country. For example, Wolfram|Alpha can now tell you how much traffic there is in the United Kingdom. In addition to answering the primary query with the total amount of road traffic, Wolfram|Alpha also tells you the types of vehicles that are responsible for that traffic.
In the example below, passenger cars were responsible for most of the traffic, with trucks and vans coming in at a distant second. Just below the breakdown of traffic by vehicle type, you can also see the total number of those vehicles that are in use.
As you might have guessed, having both of these data types available lets you calculate the distance traveled by the average car in the U.K. each year. More »
