When will the map be updated to reflect the network model? It is out of data compared with the one provided through the subscriber services.

The latest Model (version 7) is due be deployed into WebTris by the end of November

It doesn't appear that the long promised model update has gone ahead, why is this?

Paul Watkins posted this 04 December 2017

The update to v7.1 of the network model is currently going though the UAT process in our pre production environment. Hopefully it'll be deployed in December.

Having already missed the end of November timeline and now half-way through December, do we look on course for this to be updated for December, bearing in mind the holiday period that is fast approaching?

Hi James. The model passed UAT and is currently with our developers to implement into the platform. I've asked for an update on where this is and will post when I know more.

We're on version 7 now. :)

When will the next update be done?

How do these models track to the other network models that HE publish?

Paul Watkins posted this 25 January 2018

It's currently scheduled for April 2018 although there is some give and take on that from the map provider.

As for mapping between network model types... it's a persistent issue for any data analysts using a variety of sources. HAPMS and IAM IS are similar, and NTIS is similar to HAPMS and typically they're fairly close. Most difficulties lie around connectivity of junctions and where precisely links break on connection with other links (I.e, does the main carriageway link break at the lane 2 right edge of a slip, or the lane 1 left edge of the slip, etc), although it's fair to say each model will have its own flavour of mapping difficulties and those 3 are just 3 of many. Each model will have its own schedule for updates so versioning is often a overcomplicated issue. It's quite a large question

Did this go live in April?

Paul Watkins posted this 29 May 2018

Hi Hank,

Yes it went live at the end of April and it's currently progressing through the internal RIF database approval mechanism before it gets uploaded into webtris.

Any update is this live?

Hank posted this 09 August 2018

Any news on when this will be done /  was done?

Hank posted this 21 August 2018


I realize that it is only  August now and the new model went live at the end of April. Any update to when or if this is ever going to go through the "internal RIF database approval mechanism"? Could you also outline what this approval mechanism is and why it takes over three months?

It is bad enough that the minor updates to the ntis model are not reflected on this platform, but to wait a quarter of a year for the major one is frankly ridiculous. We are now having to go back to asking for traffic data which creates unnecessary delays.

This really is failing with the whole open data remit...

Version 8.10 of the model is now live on the WebTris system

Hank posted this 20 September 2018

Any reason why this took 5 months?! Nor why there was no communication about this.

Shaun Ryan-Izzard posted this 05 October 2018

This is currently being investigated. Details will be updated as they become available.

Any details of this investigation?

Shaun Ryan-Izzard posted this 4 weeks ago

Unfortunately, I have no further information at this time. As you might appreciate, such investigations can take some time, especially when there is a complex, cross business/supplier relationship involved in the delivery of the WebTris product. I will ensure that, as soon as I have any pertinent information, I will update the forum at the first appropriate opportunity.
