Self-service diagnostic

RTTI 5* Rating Readiness Check (Self-Service)

Review whether your Static Speed Limit dataset, processes and evidence are ready for an independent RTTI 5* Gap Analysis.

This check is based on the factual criteria in the RTTI 5-Star Rating Specification . It does not calculate, predict or award a star rating.

Step 1 of 7 Define the dataset and evaluation scope
Step 1

Dataset and defined scope

Define the exact dataset and road network covered by this Readiness Check. The scope may legitimately cover only motorways, highways, selected corridors or another clearly defined network.

The eventual evaluation and completeness measurement can relate to this defined network rather than every road in the country.
Step 2

Data content and legal meaning

Confirm what the dataset represents, including explicit, implicit and conditional legally applicable Static Speed Limits.

Step 3

Format and network referencing

Describe whether the data can be exchanged, positioned, interpreted and associated with the correct road extent and direction.

Step 4

Updates, timeliness and pre-announcement

Explain how changes to legally applicable limits are recorded and how quickly those changes become available to data users.

Step 5

Quality measurement and evidence

Indicate which quality characteristics have been measured and which evidence could be made available to an independent evaluator.

Step 6

Responsible contact

Contact details are required before the result is shown. They are included in the locally generated report and are not sent to TISA.
