Keeping in mind you probably won't hear them coming.

Manufacturers of electric vehicles already are rolling out noise generators for low speeds, and it's likely those will become mandatory.

A friend's Renault Zoe EV has a 'whoosh' noise generator which thankfully can be disabled in the fusebox.

To me it would be more sensible to only trigger a noise generator upon feedback from the parking sensors, instead of polluting the environment with constant sci-fi noises.

TFA has great practical information about the switch from diesel to battery. A few examples: * How do you arrange parked buses in a garage so that they can charge? Diagrams included! * Purchase cost: 2x up front compared to diesel, but improving * Operating cost: 50% lower than diesel (but labor—hiring the driver—is still 60%)

No inclusion of the knock-on benefits of NHS savings from fewer cases of diesel exhaust complications.

Yeah, but that comes out of someone else's budget, so who cares right?

- grim North Sea shithole Spend some time in other coutries and you'll yearn to return. Trust me.

Over 3 years in Spain and no plans to return to Brexitlandia. The UK has it's good points, but better quality of life can be found elsewhere.

I lived for 3 years in Spain and while I miss cheap rent and cheap public transport I don't miss the noise and bad manners.

Is there any research to back up your claim? What are the chances of getting cancer from this? Is there even a direct link? Is it better in aggregate to be an unfit bus rider or a fit cyclist?

There's actually the opposite evidence; it's worse to be in a vehicle than walk or cycle, and there's a few studies that say that the benefits of cycling outweigh the pollution exposure. http://www.breathelondon.org/south-east/project/modes-transp...

Most smart people driving in London are going to leave their car's climate control on the "recirculate" setting whenever possible. That gives you a more-or-less closed environment, running cabin air back through the car's filters rather than sucking in dirty air from the street.

But cyclists and pedestrians have no such luxury - they're breathing in the filth whenever they're on, or near, a busy road.

I don't think it's healthy at all to ride on London buses, especially in a hot summer when the buses have all their windows open. The air seems really bad inside - you can smell it and feel it in your lungs.

About half of pollutants come from brakes and tyres - http://publications.jrc.ec.europa.eu/repository/bitstream/JR... Bringing in electric buses will not decrease these pollutants. They will also not remove enough of the other half of the pollutants. The change needs to be far wider and harsher.

well, the regenerative braking will reduce brake dust a bit. Certainly not completely, but its a start.

Anecdotally, regenerative braking on an EV reduces brake pad wear by somewhere around 50-80%. It's rare to have to replace brake pads in an EV, or even to see them significantly worn.

On urban buses, which are constantly starting and stopping, I imagine it could be even more.

how will they reduce braking dust? I thought they were primarily only going to use the brake power for energy.

Thanks for that, all

Any comparison of noise generated by these buses? Of changes in the on-time rate due to changed handling/acceleration? How much smoke did the diesels put out?

The noise inside the bus seems quite annoying: https://www.youtube.com/watch?v=XEKJSMqhYKk

I've been in one of these. The noise is noticeable but not nearly as offensive as a diesel bus engine revving.

Also there's no idling that would normally cause vibrations.

What do you mean "They will also not remove enough of the other half of the pollutants." Surely they will remove 100% of those, plus most of the brake dust.

It's true that there will be an increase in road / tyre dust due to the extra weight of batteries, but I'd be very surprised if this was as much as was saved elsewhere.
