Close Following Rule

Introduction

This page covers how to configure a Close Following Rule which includes a video demonstrating the process. Typically, this rule can be used to alert you if a vehicle is travelling too closely behind another.

Close following rules are used to analyse each track in turn. Like all other rules, this will raise an alarm for a section, but the rule will look at each track individually to identify if it has broken the rule.
