Expressa - Superloop

Edited my own map including two suggestions of mine

Today's Expressa 4; 
   the 4th edition of my Expressa - where I analysed other express bus services across the developed world, then incorporated some of that into a fictional map in London.

This time, it's about comparing my years old Expressa map with the current Superloop, now that all routes (bar SL4) has been complete along with the fixated loop of doom that can't be perfectly looped.

Unorm vs TfL

Who has done it better?


Paris has,
they've gone a step further and decided to have an automated light-rail (think DLR-style)
Metro Line 15 (Grand Paris Express) do the orbital loop to go around the city centre.



Tidbit; TfL chose SL prefix instead of X(insert relevant parallel route) as the typical Joe and Jenny passenger don't pay attention to route numbers or destinations FOI request link clicky.


Updated spreadsheet of all express/limited-stop bus routes in London history
(now includes Superloop routes)



Kindly before beginning, I'd like for you to refresh (or read for first time) my initial 
Expressa post (covering express buses around other world cities) and; 
Expressa 2 post (improving London express buses).

Every express bus route created in London as of 2021



Also I swear SL2 is remarkably similar to my...

2nd March 2024: 455 dead, SL2 to life

Not often two prefix routes with the same numerical digit start on the same date.

S2 and SL2.


This day could've gone swimmingly with only two things focussed on, after everything else executed to some quality...:

Publicity

Displays.

Many blind display issues across operators, though a lot worse at one operator.



Before going into 455, it is worth noting it's two routes in one.

Of course, as a result, it's an indirect route. So indirect you can walk from Wallington to Purley and just about beat the actual 455 bus.

Overground names - my thoughts

I'd draw a Superradial map if I had the passion to
SL11 (X84) Potters Bar - Barnet - North Finchley
SL12 (215 turned X) Walthamstow - Lee Valley - Waltham Abbey - Waltham Cross
SL13 (X173) North Woolwich - Dagenham - Rainham
SL14 (180 turned X) North Greenwich - Woolwich - Thamesmead - Erith
SL5 Woolwich - Bromley - Croydon
SL15 (402 ish) Bromley - Green Street Green - Sevenoaks
SL16 (166 to Epsom turned X) Croydon - Banstead - Epsom
SL6 stop at Elephant; Oval; Brixton; Tulse Hill. Made every 12 Mon-Sat every 15 Sun, hours 0500-2400

Lately I've been sick, which is why I've not made posts lately, though I am alive, now a bit better.
Quick short post to show I'm still about, and something for me to put out.







Right, the Overground.
Please have Windrush serve Brixton, for the love of God.

Funny the last time Overground were to receive names, ex-Mayor Boris Johnson cancelled the project - like he cancelled orbital bus links (which Khan brought back as the weirdly named Superloop)

Better than 2022 I'd still say.

Past mistakes reversed

Spot the differences! (at least 4)
Do view the history of 223 on londonbuses.co.uk

I always wanted a post like this, going back in history and detailing every change that was reversed indirectly.
Then the Hillingdon consultation came about, as you can figure out above image.
This threw a minor spanner in the works as we have two almost literal reversals now, the N35 number coming back in 2024 as it returns to Old Street (perhaps Tottenham Court Road is a stretch now)

Quick estimates I calculated
U3 PVR 11 -> 17
U2 PVR 9 -> 11
U1 PVR 8 -> 0 withdrawn

Cost neutral basically

Reception among the knowledgeable locale is that U2's extension via Cowley to West Drayton is weak, with Cowley adequately served by 222 without needing help per se.
The U3 returning to Ruislip with a frequency increase is welcome (every 12 M-Sat 20 Sun/eve currently - every 10 M-Sat 12 Sun/eve proposed), though no mention of double deckers which is a little sad in this climate of routes converting recently, not to mention U3 is already allocated one on-paper in addition to temporary double decks to cover for 251 using diesels in the meantime.
   The section from Ruislip goes from a bus every 15 mins Mon-Sat and 30 mins Sun/eve into a massive uplift from U3's new frequency. True bonus.

To think 223(U3 predecessor) was every 20-22 on Mon-Fri peak hours and every 30 off-peak Mon-Fri. Overlaps on Saturday between Uxbridge and West Drayton giving the overlap an every 17-18 frequency whilst the outer ends had a bus every 34-35 minutes.

Another sad aspect is U3 not serving Uxbridge Station. Making travel more convenient should be done, rather than making it less convenient. That includes the mention of 13 minutes walk time to get to Brunel Uni as a result of U2's reroute. Also roads no longer being served by E7 by Ruislip. But hey, U2 no longer has off-peak only via Grosvenor Crescent, will serve from first bus to last bus every day.


Little blurb for Orpington scheme I won't make a full post about

B14 PVR (rerouted over R6 instead of via R11) +1 
R1 PVR (reroute via R2 to Biggin Hill) +3
R3 PVR (takes R1's Green St Green section) +2
R2 PVR -3 withdrawn
R6 PVR -2 withdrawn
estimate Orpington routes total PVR: Neutral?

The reception of the Orpington scheme is more than mellow, the Biggin Hill section receiving an increase in capacity by frequency (from every 30 to 20). Meanwhile B14 is still sadly indirect and be more indirect as the only link from Bexleyheath to Orpington.
   If anything R7 has taught us, or God forbid like P13 to Surrey Quays, a long low-frequency route, could cause problems for reliability. No one foresaw it with R7 but I'll have my tinfoil hat on.
Lest not forget R2 was a cross-Orpington route, and now with R2's death the R1 to Biggin Hill will again be a cross-Orpington route.

So 2023 TfL mergers maybe working...

With that, let's get cracking on more past mistakes.

Excess Journey Times

Performance graph

We know about Excess Wait Times

EWT = Actual Wait Time - Scheduled Wait Time
   e.g route 3 for an hour at 1600pm:
        wait 8 mins, then 12 mins, then 14, then 8, then 11, then 10, then 12 = 75 mins total
                8*4 + 12*6 + 14*7 + 8*4 + 11*5.5 + 10*5 + 12*6 = 416.5
                416.5 / 75 = 5.55
        AWT = 5.55
        SWT (half frequency of route [route 3 is every 10]) = 5 mins
        AWT - SWT =  0.5 mins = EWT



The function of Excess Wait Times is simple: Make wait times consistent

In theory this should be fine for passengers. No one likes waiting longer than they should.

Though in reality, it's ended up becoming so important that the essence of a reasonable bus journey was sacrificed, for profits. Profitability is important in a capitalist society, but above all else, losing money is something even more important to avoid.
That's the oversimplification of matters, a lot of bus routes aren't profitable after all (think of all the small single deck routes).


When two buses are sharing the same headway (i.e bunched), it's calculated as one bus in the system. As a result, you have lost mileage for that duration.

By performing better than the minimum standard, the operator is given bonuses.
By performing worse than the standard, lose mileage - the operator is fined for it.

Regulation, which is helpful to keeping EWT to standard. You're not the customer, the company is the customer, and they deliver.
As of 2023 a lot of routes had running time reductions by reducing the Peak Vehicle Requirement by one bus, fine and dandy to wait less - if your bus isn't less reliable as a result. Thus waiting longer ironically. Back to square one.

Therefore, Excess Journey Time
my idea is to add a version of EWT but in journey time form. With the intention of making EWT/EJT one whole umbrella math mess, as opposed to two systems to be mindful of being fined/bonuses for.

Saturday services on weekday holidays, possible?

Can save around £65,700 every summer holiday (i.e every year)
Is it worth it? Is it doable? It gives 3 buses a holiday at least.
Better to trade rather than all-weekday cuts to service

As you probably know, there are school-holiday Monday-Friday timetables on select bus routes. Any schedule is hard to conjure up even with the aid of Excel on our computers, still taking time from someone's hours a company would pay for just for minor adjustments in the perspective of the timetable.

Minor adjustments in the perspective of the timetable: Major adjustments in travel time London-wide.

We should also already know travel speed in London is astonishingly low, among the lowest in it's capital city peers in Europe

Therefore, is it possible to make routes use Saturday timetables on holidays, if not, why?

If it were possible to split a day schedule into segments, perhaps that'd be easiest...
Or do a 241, 5 bph on M-F shopping hours but 6 bph M-F peaks and Saturday

Route Test fleet (Single Decks upgradeable v2)

I say this thinking about how routes 42 170 and 201 all had MECs tested by Go-Ahead as Red Arrow routes 507 and 521 were converting to electric Enviro200 EVs.
The 42 passed. The 170 passed. The 201 failed (due to Roupell Road), 646/648 failed for somewhere.



Stagecoach tried with 314 using Citaros freed from 227, the test failed by Elmstead Woods as the roads curve narrowly. Instead the Citaros got sold to Cyprus where a rival operator arsoned them. Bad end to great machines.
(Stagecoach should've tried with P4 too)
Another failed attempt includes Metroline with double deck TAs and route 251. Failed due to Totteridge area.


Since the previous 70-capacity 201 test failure, Lambeth council installed Low Traffic Neighbourhood, and didn't remove it like some other boroughs wisely did, in spite of increased traffic on main roads which hasn't dissipated to thin air as some would've liked. This made me think, following 201's tender announcement keeping it's YY64-reg Enviro200s I adore.

The 201 can realistically use 12m buses now.

Why?
Only buses are allowed to turn into Roupell Road [from A205]

I am under the belief a sizeable amount of single deck routes that use 10.8m vehicles can use 12m sized vehicles. The 108 has proved it, the 360 has proved it, the 444 has proved it. The 203 and H37 were 10.8m single deck routes until 2011-12.

The purpose of this is manyfold
- Reduce the amount of times TfL and operators need to verify a route test, making this one-party
- Insure the highest size vehicle can be used on buses, ensuring maximum capacity achieved
- Eliminate discrepancies

Just recently, new routes SL1 and SL2 were tested using an LT.
Just recently, the 289 was awarded as a double deck route (currently single deck), just like happened to 80 - making Sutton (A) almost fully electric, Thornton Heath (TH) will also be fully electric.

Realising it deeper as I publish this post
Electric range is more important but can't quantify it myself
