It took quite a while, but the paper about the history of high-speed rail planning in Italy that I co-authored with
@beriapaolo.bsky.social
is finally out! It's open source, so you can read it at length (it is pretty long), But here is a TL;DR: đź§µ

Isn't vibe-based politics the natural end of post-mass parties and low-engagement politics? Isn't this what the media and the "politics as opinion polling" have been working toward since the 1990s? We live in an era of ideologically shallow masses and deeply ideologized elites, don't we?

One cannot fully understand the Italian urban planning discourse of the last 70 years without looking at that map and knowing what "dissesto idrogeologico" means. And how 1966, the year of the "urbanistic disasters", the floodings in Florence and the landslide of Agrigento was a turning point.

From a Diab & El-Geneidy 2015 paper: Just moving stops far-side and removing the right-turn/stop conflict could save up to 8.7% of running times on line 165 in Montréal, equivalent to adding 7-9 trips per weekday per direction for free We leave so much on the table.

I guess today Toronto won the day. Having these issues during ypur first winter, fine. During your second winter, not good but ok. On your third winter, hell no. What is it with the Canadian transit industry forgetting that winter exists?

The Cirenaica neighbourhood in Bologna, developed as a working-class area during the first three decades of the 20th century, is an interesting example of how the principle of "environmental areas" is applied deliberately even when a full through grid could be established

Find someone who lives you as much as contemporary tram designers in Italy loves to overinterpret the UNI-FER definition of "metrotranvia" and unnecessarily fence off their entire right-of-way, achieving both higher capex, higher opex and total ugliness. That's talent. (Bergamo, T2, u/c)

I find it pretty wild that Eugene BRT's designers could get away with an alternate-direction contraflow bus lane with so many driveways and small streets just managed with stops and a bunch of "look both ways" road signs. When you want, you can, I guess.

To add some perspective to the free bus debate, these are the opex per pessamger trip of different modes in the Greater Montréal area from an STM presentation. The metro has by far the lowest unit opex, while buses can be up to 10x more expensive in the case of suburban ones (Exo bus)

In Turin, the multiway boulevard typology known as "corso" is a dominant feature of the city's urbanism. The side access roads provide parking, collect flows from local streets, and sometimes provide for an indirect left turn. Curbside transit lanes run undisturbed from right turns and curb access.

Une chose que j'ai malheureusement pris du temps à comprendre est que, au Québec, les besoins des urbains sont complètement évacués du débat politique. Le système de vote uninominal par comté et la structure de l'offre politique fait en sorte qu'on est rayé de la carte.

Paris pedestrian refuge and traffic islands markers. Almost the same design as today's The permanence of place-specific street design elements over time is a very interesting phenomenon. It makes the case for road engineering as a more place-bound "craft" rather than a "hard" STEM science.

During the winter Olympics, Trenord is going to step up service to out-of-town venues, including a direct half-hourly takt between Milan and Tirano with service well into the late night/early morning. Quite a feat for Italy where, apart from a few busy corridors, late evening/night service is meh

Very conforting to think that Québec provincial politics is going to revolve around the debate about a referendum nobody wants because voters are fed up with the CAQ and PLQ is a scandal-addicted party, which will result in the PQ misunderstanding it for support for independence.

That's a good argument, but as a person who think that we do not need to reanalyse every planning problem from first principles but rather look at what others did, I think that the fact that a wide majority of HSR systems worldwide has near-CBD stations tell us something.

Thos is true,.but for doing this you need a framework to do track sharing with Exo (no room to add separate tracks) and you also need funding to fully modernize Exo's St-JerĂ´me with high-performance EMU, stations with level boarding and full electrification even oitside the shared corridor.

It's interesting that grade separation in urban contexts was essentially achieved in many cities throughout the developed world by WWII, but by the 1960s the grade separation effort was de facto almost abandoned in North America but continued elsewhere.

My understanding of the current political moment in Italy is that Meloni has been able to intercept the conservative petit-bourgeoise voting block that after the collapse of the postwar political order in 1992-93 first moved to Berlusoni, then erred home-less from Renzi to 5-star, to the Leaugue.

The sort of NIMBYism I can get along: a multi-story parking was planned atop this existing parking in Bologna as part of the tramway works to "compensate" for the on-street one lost along the corridor. It was NIMBYed by the neighbours and the city decided to drop it, saving several millions.
