The author discusses current techniques in relation to their broad advantages and disadvantages. The scope of the various methodologies is outlined, and examples are given of the use of the technique for transport planning processes requiring large amounts of data. The most consistent advantage of all the applications reviewed, ranging from traffic surveys to public participation and evaluation of highway schemes, is the supply of a permanent record from which information can be extracted at any time. The reduction in the number of enumerators required for short periods of time is a further important advantage. Often limited coverage and poor weather conditions contribute to the high cost of aerial photography which is a major disadvantage. Personnel will often need to be on standby for a number of days before good survey weather occurs. However, recent developments will enable the survey itself and data extraction costs to be reduced. Some unusual applications, such as highway design and driver behaviour, signing and aerial pedestrian flow studies are outlined. (TRRL)
