The field of vehicle routing has seen the development of a variety of mathematical techniques. While the practical application of these techniques has depended on the use of spatial information such as road networks, these techniques have developed independently of other users of spatial information. This paper argues that traditional routing techniques(More)
Geographic Information Systems (GIS) represent an application of information technology (IT) in business that has yet to reach full maturity. Like other forms of information system (IS), the development of GIS in commercial organizations has been greatly influenced by developments in IT and in the subsequent availability of software to exploit these(More)
