Linear Referencing for Network Analysis of IED

Abstract

This paper outlines a motivation for associating IED events (and other significant physical and human geographic features) with the road network, describes the use of methods known as linear referencing in order to do so, and presents an example of how linear referencing of several types of events can occur. This is followed by a description of several measures of network density of events, and a demonstration of how linearly referenced events can be combined to analyze spatial coincidence of different event types. This is followed by suggestions for future research including the development of network based spatial statistics, optimization of network services based on the linearly referenced events, and geographic information system tool development to integrate these methods.
