Temporal Properties

The Special Designation and Highways Dedication features contain information on restrictions which apply to a temporal period. The different temporal properties have been categorised and the different categories are detailed below. In addition, they have been given a hierarchy within the RAMI product which is illustrated in the diagram below.

Named Date

A Named Date would be when a restriction applies to a specified date which is named. For example, All Year or January. There are no further sub-categories of a Named Date.

Date Range

A Date Range is provided when a restriction applies between two dates and there will always be a start date and an end date. These two dates can be specified using two different data types: either StartDate and EndDate or StartMonthDay or EndMonthDay.

The StartDate and EndDate will always be used for Date Ranges for Special Designation features. These are formatted as YYYY-MM-DD, for example, 2016-09-20.

Day Period

A Day period would be a restriction which applies on a specified day. A Day Period is made up of the following properties:

  • Named Day – A restriction which applies to a specified day which is named, for example, Monday or Weekends

  • Named Period – A restriction which applies to a specified period which is named, for example, School Holidays.

  • Time Period – A time period is made up of a further two properties:

    • Named Time – A restriction which applies to a specified time period which is named. That does not necessarily relate to the same time each day consistently across the country, for example, Peak Time.

    • Time Range – When a restriction applies between two specified times which will always have a start time and an end time. These data types are formatted as HH:MM:SS and will use the 24hr clock, for example, 16:30:00.
