Today's issue of Local Transport Today has some comments from me, in the item about the DfT's Local Transport Infrastructure Carbon Benchmarking Tool (LTICBT).
Or if you have the PDF, it's on page 20 .

Won't be short of bedtime or bathtime reading this weekend.
DfT has published its latest Appraisal, Modelling and Evaluation Strategy, a set of research reports, and the 'live' TAG updates. There's a lot more than what's in the photo!
Plus the latest LTT out today.... and some interesting American research to catch up on if that's not enough...

A quotation from Richard Steele
It’s a particular Observation I have always made, That of all Mortals, a Critick is the silliest; for by inuring himself to examine all Things, whether they are of Consequence or not, he never looks upon any Thing but with a Design of passing Sentence upon it; by which Means, he is never a Companion, but always a Censor. This makes him earnest upon Trifles; and dispute on the most indifferent Occasions with vehemence.
Richard Steele (1672-1729) Anglo-Irish writer, journalist, playwright, politician

Spent some time recently tracing the history of the discount rate guidance in various recent editions of the Green Book and its supplementary documents.
The guidance has changed, and in the latest Forthcoming Change notices from DfT, TAG is now taking more of it on board.
It’s a complicated story. The kitchen table came in handy…
Look out for the resulting thoughts, in this week’s edition of Local Transport Today.

Released ore v0.25.1 (and a number of other releases) which closes most of the behavior gaps with bundler.
Released appraisal2 v3.0.4, which now works in all scenarios I’ve tested using ore via —gem-manager=ore

Calling all Shakespeare fans in #transportplanning or economic #appraisal...
Tonight is Twelfth Night.
To celebrate*, I’ve hidden a phrase from that very play🎭 in my blogpost on the latest changes to #TAG. Can you spot it? Comment below if you do.

* And definitely not as a contrived excuse for a blatant plug for my run-down of all the latest updates to the DfT 's Transport Analysis Guidance. Not at all.

“You’re the page 3 boy”, a colleague said…
That’s one way of putting it!
Today’s issue of Local Transport Today includes my piece on the new road freight values of time that DfT is proposing:
🔴 What’s the problem with the existing values?
🔴 Why does it matter?
🔴 What’s the proposal?
🔴 And what will it mean for appraisal results?As a bonus, there’s a Graham ‘explainer’ on another topic too.
And there's a feature on the recent Transport Planning Society paper that I contributed to, about the Green Book Review.
So if you’re not already an LTT subscriber, this edition is a very good one to start with - but I'm biased!

Lots of technical updates on transport modelling and #appraisal coming out of #DfT recently.
My application to host #Strictly might have to wait until I've read all these and responded to the mini-consultation on road freight values of time...

Updated: my ready-reference chart for the #AMAT cycling infrastructure categories.
I've updated the valuations to 2023 prices and values, in line with the latest #TAG #databook .
The chart helps with picking the correct DM and DS cycling infrastructure categories when running an active travel scheme through AMAT.
It also covers using these categories as proxy values for other improvements to journey quality.
Find it at https://grahamjames.co.uk/amat/
The previous version using 2010 prices and values is still there as wekk, in case you need it for an older appraisal that's still using those.
