Rating Highly recommended, 5/5. One sentence review Outstanding and original description of artificial intelligence (AI) in the 21st Century, the problems it could pose, and a lucid proposal for ‘provably beneficial AI.

Today I am presenting at the Transport Research Board’s 2021 Annual meeting, aka #TRB2021. I say ‘presenting’ but in fact, the talk was a pre-record - see the video below!

2020 has been a crazy year all-round with US elections, Brexit negotiations reaching their conclusions and of course the global pandemic that has swept across countries and disrupted lives worldwide.

I gave a talk today at the ‘Ideas with Beers’ seminar series, hosted each Tuesday for the past several months by Brian Deegan, an experienced transport infrastructure engineer and Principal Design Engineer at Urban Movement.

Having recently acquired a new laptop, an Entroware Proteus (shown below), I had to remind myself how to set-it-up for my needs. This includes the usual things like document editing, web browsing and email.

Last week I presented at UCL’s summer school which, by all accounts, was a very successful event in which many people learned many new skills. The presentation format was a refreshing changes from the PowerPoint slides you’re often asked to prepare.

UseR! is the highest profile and, I believe, most popular annual meeting for R enthusiasts, known affectionately as ‘UseRs’ for the purposes of the event. For those who have been living under a stone for the past decade ;) R is an open source statistical programming language that has seen explosive growth since ‘data science’ became a buzzword.

I am very happy to announce that the paper stplanr: A package for transport planning has been published in The R Journal (Lovelace and Ellison 2018) 🎉. This is the result of around 3 years of work: it took us (co-author Richard Ellison and me) over a year to get round to writing the paper after the stplanr package was first released on CRAN in November 2015 (see its archive on CRAN for details); it wasn’t until March 2017 that the paper was formally submitted.

The previous post demonstrated a new method to aggregate overlapping lines. It showed how to combine 2 lines that have an area of overlap. More excitingly, it led to the creation of a new function in stplanr, overline_sf(), that lives in the development version of the package.

Introduction It’s been a busy 12 months but with the Geocomputation with R book nearing completion1 I’ve finally found some time to update my blog and do a bit of thinking, about the tangled topic of line aggregation.
