Summary A little‐used method of estimating road traffic flows between two points is to record the registration numbers of vehicles passing each point in one direction and then compare the two lists of registration numbers to discover how many appear in both lists. One of the disadvantages of the method is that some inaccuracy in recording the numbers is inevitable and inaccuracy causes the numbers not to match when they should. This paper describes the application of the registration number method to a long‐distance traffic survey and develops an estimate of traffic flow which compensates for inaccurate recording.
