I was cycling a little off my usual route and came upon this rather nice brand new segregated cycle lane in Tolworth, just here

Here's a view of it:
Now you'll notice this section of the cycle lane has been completed, bar the white lines. I know because I ignored the sign and cycled along it. If this was a motor road, the contractors would quite rightly attract the attention of the papers and the Council for causing inconvenience and unnecessary congestion. But the same standards don't apply for cycle lanes ... *sigh*

Black Cabs and The Cost of Pollution
As usual, this blog gets the news before the BBC, who reported in a rather dumbed-down way the Commons Environmental Audit Committee report, which said that failure to reduce pollution had put an "enormous" cost on the NHS and could cost millions in EU fines.
But the BBC don't tell you much about where all this pollution is coming from. For in-depth analysis, you need to come here...
In Central London, if you walk around during the day, you'll notice that there are a few private cars these days. Most of the traffic is black cabs and commercial vehicles. A lot of the 'private cars' you'll notice have the tell-tale window sticker of the private hire vehicle. This is testament to the success of the congestion charge. But could it be that the people who used to drive into central London are now using cabs more?
Not that it matters much who is using cabs. As I reported before, The Mayor's draft Air Quality Strategy says " In central London where the [pollution] hotspots are, taxis are a particular problem, accounting for 35 per cent of emissions from exhausts". It's pretty clear then that you can't tackle pollution (or congetion) without reducing taxi usage. But the political classes are scared stiff of the black cab lobby, which has power out of all proportion to its membership. Black cabs have many of the same privileges as public transport - their own free parking, the right to use bus lanes - but they are in many ways as damaging in terms of the pollution and congestion they cause as single-occupancy private vehicles - which is essentially what they are much of the time.
Now it's pretty clear that there is a need for cabs, and they have a valuable role to play in enabling people to use public transport. But a lot of cab journeys in central London could be conducted entirely by public transport. And the buses would run a lot quicker if there were fewer cabs clogging up the bus lanes. In addition, cabbies know every nook and cranny of London streets, and turn the quieter streets into rat runs, which damages quality of life for London residents and discourages cycling.
But no political party or newspaper would dare say any of the above.

Free Speech and the Daily Mail
This article about speeding/bad driving attracted a good selection of comments, largely articulate and informed. All the comments have now been pulled. What are they afraid of? That the general public are capable of better writing than their columnists, perhaps? (well, the bar is pretty low)

Sensible article about cycling
from the Evening Standard.
Less of this please, otherwise I'll have to give up blogging. I'm sure I can still rely on the Mail for the usual ignorant, prejudiced cyclophobic nonsense though.

Richmond Park Car Parking Charges Go-ahead
It seems that the car parking charges for Richmond and Bushey parks have got the go-ahead...for now. This BBC report explains that a Lib Dem amendment to scrap the charges was defeated, although a Tory amendment that 'regrets' the charges was passed. The Tory PPC for Richmond Park, Zac Goldsmith, has made noises to the effect that a future Tory government will try to reverse the charges, but there's no firm commitment that I have seen. I strongly suspect that this is just pre-election posturing which will be forgotten after May 6 in the scramble to cut the budget deficit.
What the BBC report doesn't tell you is that Jenny Tonge (Lib Dem) said that instead of penalising local people to park, "rat runners" should pay a toll "towards the upkeep of the roads" (citation). Which is what I said in my previous post on the subject. Of course, Tonge, unlike Kramer and Goldsmith, doesn't have to get elected.

Piccadilly Circus Revamp
Westminster Council are spending £14M digging up the world-famous landmark junction, and re-engineering the surrounding streets to make them more pedestrian-friendly.
With that amount being spent on de-congestion, you would think there would be some arrangements to improve the sorry state of cycling in the area. Well, I've not found any mention of it, which isn't that surprising given Westminster's usual anti-cycling stance and opposition to road-safety measures such as 20MPH speed limits. Given that TfL are being asked to stump up £7M of the cost, you would think they would weigh in with some preconditions, especially as Piccadilly Circus is exactly the kind of place tourists will cycle to on their hire bikes. If and when (God forbid) a few of them get run down I'll claim my 'I told you so' card. Hopefully it's still early enough for sense to prevail...

LCN Route 3, or The Clapham Crawl
LCN Route 3 is a cycle route that mainly uses quiet backroads to get you into central London from the southwesterly suburbs.
Using backroads is usually a good strategy, because they tend to have low traffic volumes and often traffic calming to keep vehicle speeds down.
However, the real bugbear is that minor roads almost always have the priority against you. In other words, any time you get to a junction, you have to give way. Lots of Give Ways really slow you down. They make cycling unattractive and more dangerous because unless visibility is good, you have to slow down considerably or risk not being able to stop if there is any traffic on the major road.
So the logical thing to do if you were designing a system of backroads as a cycle route is to change the priority to favour the cycle route. Simple and obvious...except if you're a traffic engineer. You can always rely on them not to have considered the effect of junction priority on cyclists. There's one exception which shows it can be done: Meadow Road now has the priority where it crosses Fentiman Road, which favours cyclists (you still have to watch out for vehicles encroaching or failing to give way, of course).
In Clapham, there is a series of junctions on Route 3 where the priority is against cyclists. Here's a map of the area:
View Larger Map
Here's the first junction. The Chase is a wide but very quiet road leading north from Clapham Common. It really ought to have a segregated path. Route 3 going north then turns right into Hannington Road (below).
Making the right turn isn't normally a big problem, but of course all right-turns are somewhat risky, particularly for kids.
Going the other way you turn left from Hannington Road into The Chase, but your vision is obscured by parked cars, so you have to slow right down. The logical thing would be for the cycle route to have priority. Bear in mind there is little traffic here so there would be no real issues with this. You could build out the pavement south of the junction to shield traffic coming from the left.
Just a hundred metres further on, there's a staggered crossroads, where Lambourn Road crosses and the cycle route goes straight on from Hannington Road into Broadhinton Road. Again, the priority is against the cycle route and again without good reason as there is little traffic on either road. (below)
Another two hundred metres further on there is a major junction, with North Street.(below)
No surprise the priority is against you here, but there's no attempt to make life easy. No central refuge, no mini-roundabout or lights, nothing. You can wait a long time in rush hour before there's a gap in both lanes of traffic big enough to allow you to get across.
Another 70 metres further on, another crossroads. Again both roads are quiet but the priority is against you with no good reason. (below)
Next, in another 140 metres, we have Turret Grove junction with Rectory Grove. This is a T junction so the priority is against you. It's easy enough to make the left turn going north, but going south you have to make a right turn and there is a ridiculous piece of road design to make this as difficult and dangerous as possible.
First, Turret Grove is no-entry to motor traffic, and this is enforced by an island with a narrow cycle path through it. (below)
This arrangement causes the following problems:
1. You cannot make the right-turn at any speed even though visibility into Turret Grove is good. The cycle path is both narrow and at an acute angle. So you have to slow down and you're more likely to be held up by oncoming traffic, which increases the chance of being rear-ended.
2. You end up in exactly the wrong place in the carriageway, invisible to traffic coming up Turret Grove, and yet forced into the middle of the road by the parking bays you can see in the above picture.
So in summary, the road designers have done nothing for cyclists, except one thing that has made the road more dangerous. Now a couple of give-ways aren't a problem, but when you have give-way junctions with this frequency, it really starts to slow you down. That's when impatient cyclists start to take risks.
