There is an increasing quantity of road transport data that is becoming available. Both historical archives, in some cases consisting of decades worth of data, as well as new types and sources of data are being made available. In the future we can expect these new forms of data to be available in near real-time. What uses can be made of this data?

In this talk we shall illustrate how road traffic data is helping modellers grapple with the nature of traffic flows and congestion. New forms of data are also an opportunity for service providers to assist travellers and transport operators. We shall consider a specific application where historical data can be combined in a statistical model with real-time traffic data to make better predictions of journey times. Surprisingly, our findings suggest that good prediction tools can be constructed that have rather modest online requirements.
