I never walk out in front of cars until I have made sure they see me. You never know what's going on with that driver.

> I never walk out in front of cars until I have made sure they see me. Optimist! ;)

By "made sure they see me" I mean they're clearly stopping for me.

Ctrl+f "pedestrian" Only one result and it's not even about roundabouts. This is how American traffic engineering is done.

Is your argument that roundabouts are bad for pedestrians? If so why?

More that they aren't really taken into consideration, as the article shows by not showing.

All the different rules for roundabout are fun. In the UK you’re expected to filter to the outside leave. In Iceland the person on the inside has priority to leave so you can still enter the roundabout but need to watch for someone already on the inside wanting to leave at your first exit. The rules are similar to the Netherlands in that you either go straight or 3rd exit from the inside and should only go first exit…

> “In the UK you’re expected to filter to the outside leave.” In practice, large multi-lane roundabouts in the UK usually have lane markings as you enter, with specific lanes for each exit. In general, so long as you were in the correct lane as you entered the roundabout, the lane markings should guide you to the correct exit and you shouldn’t have to do any filtering.

Except the surprisingly common case that lanes are mislabelled... Ie. "I was in the lane marked M4, I followed that lane round perfectly, and suddenly the label in the lane changed to A205! I better change lanes. Oh actually the lane I was just in is now marked M4 again."

The problem seems to be that a lane that goes to two places is sometimes marked inconsistently with each of the two places - meaning you think you are in the wrong lane, when you are not.

And the good ones have lane markings that guide you to the exit as you go around too

Careful with terminology too, because "inside" and "outside" don't mean the same thing to different drivers, particularly in the UK compared to elsewhere. Many people hear "inside lane" on a motorway and think it's the "fast lane" near the central divider but that's actually the "outside lane". ( source: https://dictionary.cambridge.org/dictionary/english/outside-... ). But that terminology has been confused over tim…

Do you know the origin of the UK use because that always confused me as it’s obviously wrong from the drivers perspective of the road! My wild guess would be that from the drivers seat you look outside to the fast lane and look across the inside of the car to look to the slow lanes.

The fast lane is the furthest lane away from where you'd enter the motorway, therefore it's the outside lane (or so the logic goes!)

> But NL is also a huge bike country. And at most roundabouts, bikes have right of way. The fact that it's on a case-by-case basis an not actually a consistent traffic law is really awful. To add insult to injury, the only signage is usually a yield sign painted on the road that is invisible as soon as it's dark and the road is wet. And this is of course further combined with the absolute scandalous amount of cyclist…

It's supposed to be consistent: within built-up areas ("bebouwde kom") bicycles have priority, outside of those areas they don't have priority.

In built-up areas it's often (usually?) a bicycle lane, i.e. on the same piece of asphalt as where the cars are. In that case, bicycles always have priority. It's the same as taking a right turn: wait for bikes that go straight. Outside built-up areas it's always a separate bicycle path, often with some distance from the car lanes.

The confusion can arise inside built-up areas where there's a separate bicycle path, usually close to the car lanes.

>The lack of lights and increase in number of crossings (for non-tiny ones) make them pretty terrible to cross as a pedestrian. This can surely be remedied by having the crossings being raised, acting as speed bumps for the cars and providing a better crossing experience for the pedestrian (or cyclist). I'm not entirely convinced that the lack of lights would inherently mean that roundabouts are less safe for pedestr…

Here in the UK, any difficult-to-cross junction will have a roundabout, simply because our road designers love roundabouts. And for large/busy roundabouts, cars will be in constant motion meaning there won't be gaps in the traffic flow for pedestrians to cross. If you try to cross [1] on foot at a busy period, it's not a particularly fun experience. Of course, I'm not sure any road layout could make such a junction e…

> ”And for large/busy roundabouts, cars will be in constant motion meaning there won't be gaps in the traffic flow for pedestrians to cross.”

This particular roundabout has a signalled pedestrian crossing on the southern side. Cars will get a red light (and pedestrians a “green man”) allowing them to cross safely.

But you’re right that there are too many UK A-roads and roundabouts that are a nightmare for pedestrians, lacking safe crossing.

(Warning: Anecdata) There was a multi-lane roundabout near me with traffic signals and pedestrian crossing signals and all. It was an absolute nightmare to drive through, bike through, or cross on foot. Cars pressured one another to drive aggressively, pedestrians had to wait for walk signals, cars got confused and blew through the crosswalks by accident even when pedestrians had walk signals, bikes were an afterthou…

unsignalled crosswalks at roundabout exits have a pretty high fatality rate. People on the roundabout are still checking their mirrors, wondering if they took the wrong exit, and are otherwise distracted while leaving the roundabout, and have a habit of just running over a pedestrian.

It’s often had to cross the road after a roundabout as drivers are too busy accelerating to get off the roundabout

For on near us it’s even worse as even though there’s an island to aid crossing the road signs are place in position that limits pedestrians view of the traffic leaving the roundabout

Fortunately they built a light controlled crossing a 100m further on

Wow, I'd never thought of it like that. I'd always assumed "outside lane" was the lane closest to the "outside" of the road (ie. the edge) and "inside lane" was the opposite, and was very confused when I found out some people used it the other way around.
