You remember a fragment of a song that sounds like it’s from the eighties. You do some research, but you struggle to remember where you heard it, and when. Your guesses are more imagination than recall. No hints come to mind.  When this happened to Questlove, he was stumped. He decided to transform this research […] The post From research to imagination appeared first on Herbert Lui.

The major roadworks at the Bow Roundabout are complete, indeed were completed five weeks ago apart from the opening of the contraflow beneath the flyover. Now it seems this filter lane won't be opening until later in 2025 while TfL "complete more works to protect the structure," so let's not delay my in-depth report into all the changes at my local roundabout. The Bow Roundabout is a significant split-level interchange which opened in 1967 where the A11 and A12 meet. The former took the flyover and the latter the underpass, so it's only those switching between the two (and local traffic) who need to use the roundabout. With the opening of the Silvertown Tunnel TfL decided physical mitigation works were needed - smoothing a few curves, improving kerbs, widening a couple of carriageways and diverting the aforementioned contraflow lane. It's amazing that this somehow took five months given how little fundamentally changed, but the location of the roundabout above the River Lea brought with it additional challenges. Traffic on the roundabout It's still a bit early to decide if the extra lane has eased the traffic. I haven't seen any bad jams recently but I may just not have been looking at the right time. Also the Silvertown Tunnel's only been open for a week, plus that tunnel doesn't lead here anyway so goodness knows why TfL thought this roundabout needed modifying. If anything you'd expect the new toll on the Blackwall Tunnel to have reduced the traffic here all by itself. contraflow lane from Marshgate Lane which no longer has its own separate access point. Instead it diverts under the flyover, or will do when it opens, which should be a safer prospect all round. Many's the time I've forgotten the contraflow lane exists and stepped out to cross without looking both ways, so it should be harder for local pedestrians to walk in front of traffic now it's been diverted. longer than it did when I first moved here. Traffic lights on the roundabout Previously every arm got 16 seconds, regular as clockwork. From Bow Road: 4 seconds for bikes then 12 seconds for vehicles From A12 northbound: 16 seconds From Stratford High St: 4 seconds for bikes then 12 seconds for vehicles From A12 southbound: 16 seconds But that's now changed, with traffic emerging from Bow Road the major beneficiary. From Bow Road: 4 seconds for bikes then 18 seconds for vehicles From A12 northbound: 18 seconds From Stratford High St: 4 seconds for bikes then 10 seconds for vehicles From A12 southbound: 18 seconds One complete cycle still takes 64 seconds because these intervals overlap a little. But traffic coming off Bow Road now has 50% longer to enter on green which is excellent, helping to reduce queues and often meaning every vehicle waiting slips through. If the traffic backs up less often that also means fewer vehicles idling and belching fumes outside my front door so I'm all in favour. Meanwhile traffic coming off Stratford High Street now has 17% less time, which I thought was bad until I realised there are now three lanes instead of two, and that's why they've been able to reduce the time while increasing throughput. Pedestrians And this matters because pedestrians don't always wait patiently on the pavement for the man to go green. Often they'll launch out across a gap in the traffic thinking it looks safe, whereas the Bow Roundabout is in fact a dangerous maelstrom where traffic is capable of appearing suddenly and without signalling. Make that gap 50% wider and the chance of a very nasty accident increases. Also I believe one of the countdown timings is incorrect, being a few seconds too short, so even those who've crossed properly could find themselves midway when the lights change. Start of Bow Road: 1 lane (5m), countdown starts at 3 End of Bow Road: 2 lanes (8m), countdown starts at 5 Start of Stratford High St: 2 lanes (9m), countdown starts at 5 Stratford to centre of roundabout: 2 lanes (9m), countdown starts at 5 Bow to centre of roundabout: 3 lanes (12m), countdown starts at 5 End of Stratford High St: 3 lanes (12m), countdown starts at 8 I wonder if you can see the dodgy countdown in that list. Mostly as the number of lanes increases the length of the countdown gets longer, which is what you'd expect. One lane 3 seconds, two lanes 5 seconds, three lanes 8 seconds. But one of the 3-lane crossings only has a 5 second countdown - the crossing between Bow and the centre of the roundabout - and that's not long enough at all. Cyclists cycle racks have been provided under the flyover, but no sane cyclist would leave a bike there. Things thus aren't particularly worse for cyclists but neither are they any better. first junction in London where they were introduced as a response to two fatal accidents after the blue paint first went down. A ghost bike memorial to one of those deaths is still chained to the railings above the river. So what's intriguing is how many cyclists continue to jump the lights and ride onto the roundabout anyway. The synchronisation of those lights is annoying because they're deliberately set up to stop you - if the first set isn't red the second always will be. But I did some counting for ten minutes and I reckon only half the cyclists waited and the other half made the choice to launch off past red, which is a lot more than I expected. All that effort to improve the junction for cars but little for pedestrians and nothing extra for cyclists - let's just say it doesn't help.

It was nearly Easter Sunday today. Easter, as you may know, is the first Sunday after the full moon after the spring equinox. First Council of Nicaea set the rules for determining the date of Easter. spring equinox was always on 21st March, even when it wasn't. 2019 it made four weeks difference. same thing will happen in 2038 when Easter will be kicked ahead from 28th March to 25th April, the latest possible date. 19 year cycle of full moon dates and used that instead. complicated cycle involving epacts, golden numbers and leap years so let's not get into that here. ecclesiastical full moon in the period 21st March to 18th April inclusive. new moons rather than full moons. ecclesiastical new moon on or after 8th March. 1st Jan, 31st Jan, 1st Mar, 31st Mar, 29th Apr, 29th May, 27th Jun, 27th Jul, 25th Aug, 24th Sep, 23th Oct, 22nd Nov Officially speaking, Easter is the first Sunday after the ecclesiastical full moon after the ecclesiastical equinox. This year that's 20th April, the Sunday after the imaginary full moon on 13th April. It doesn't always match up like that. But most years it does, including this year. So it wasn't nearly Easter Sunday today, sorry. But a few tiny tweaks to the rules and it could have been.
