OPERATIONAL RESEARCH APPLIED TO VEHICLE LOCATION. NAV 85 - LAND NAVIGATION AND LOCATION FOR MOBILE APPLICATIONS - PAPERS PRESENTED AT THE 1985 CONFERENCE OF THE ROYAL INSTITUTE OF NAVIGATION, YORK, 9-11 SEPTEMBER 1985

The author explores the framework for an operational analysis in choosing vehicle location systems. Three categories are defined: user only systems, supervisory systems and command and control systems. Each is applicable to different situations, e.g. Private cars, airport vehicles and taxis respectively. Different functions are important to each and examples of the parameters to be taken into consideration are listed. An example is given of the application of operational research to improve the control of airport vehicles undertaken by an airline at a major airport. The results were surprising in that although vehicles were often out of position this was not found to be significant whereas the scheduling of vehicle servicing was found to be very beneficial. High navigational accuracy is rarely necessary and, from the point of view of safety, accuracy applies only to driverless automobiles. The operational use of accuracy is known as the efficiency of navigation and this is particularly relevant to vehicle location. The concepts of absolute accuracy, repeatable accuracy and relative accuracy and their use in the field are outlined. Other navigational requirements of vehicle location systems described include integrity, reliability and availability. (TRRL)
