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?

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. :)

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

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.

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

Shaun Ryan-Izzard posted this 05 October 2018

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

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.

There was a break down in the procedure in which the data feeds in from our supplier to another database, and then onwards to RIF with a handful of other non model related issues which impacted the load of the model (site access, resources, etc).

Suffice to say it took too long and this has been highlighted sufficiently. I'm not proposing there's a full document detailing every single step of the failure but we're aware of the issues and they're corrected for when NM9 drops. There's also been a handover (& duplication) of procedural knowledge so there isn't any time lost due to the process being known by a select few.

We will post when NM9 is published onto WebTRIS though be aware we don't have an exact time line for this as the drop date isn't in our control.
