Introduction

The Sections page offers each rule a great level of flexibility. It allows each section to be customised so they use their unique rule parameters or specific sections can be disabled so they are ignored by the rule. Sections can be updated individually or in batches. Those sections which are not updated will retain the default values configured on the General and Advanced pages.

Changing Section Settings

Because these settings are “overrides” to the default values configured elsewhere on the rule they do not operate using the traditional Edit / Save process. Instead you must use the following approach:

Overriding a Section Setting

  1. Put the rule in Edit mode by selecting the Edit mode

  2. Select the sections you want to override by using the checkbox in the first column.

  3. Enter each override value in the fields above the section list and select Apply against each entry.

  4. When applied, the override values will appear in the list alongside the selected sections.

Removing an Override Setting

  1. To clear a setting, firstly select the sections you want to change by using the checkbox in the first column.

  2. If you have values in the override fields clear them using the Clear button or delete the value from the text box.

  3. Then against each field you want to clear, select the Apply button.

  4. The values against the selected section will be cleared.

For carriageways with a large number of sections you can filter the visible list using the Filter bar. Dragging from the left and right will produce a reduced window of sections. If you then Ctrl+Drag one of the bar buttons then you can “slide” the window down the list of sections until you find the area of road you are interested in. In addition you can select Show Modified which will list only the overridden sections. This is useful when you want to edit any previously configured sections.

Section Settings

Break Allowance: This allows you to override the break allowance for this rule on selected sections.

Allowance Increment: This allows you to override the allowance curve increment, if used, on the selected sections.

Allowance Decrement: This allows you to override the allowance curve decrement, if used, on the selected sections.

Min Speed: This allows you to adjust the minimum speed filter value on the selected sections.

Max Speed: This allows you to adjust the maximum speed filter value on the selected sections.

Disabled: This allows you to disabled the selected sections for this rule. This will result in no alarms being generated for this rule in the selected section.

Detect Option (Experimental): This is used to identify the selected sections as enforcement detection areas. These areas are typically used to analyse tracks prior to enforcement checks.

Enforce Option (Experimental): This is used to identify the selected sections as enforcement areas. These areas are used to apply the enforcement rules.
