Does extra parking calm traffic? Yes

We're going to be looking at the Clifton "calming traffic through more parking" plans, to show that this isn't really a self-centred proposal by the Clifton Parking Faction (our comrades, the Keep Parking Free team), but instead a dedicated attempt to reduce risk in a busy city.

Here is the Shaldon Road/Muller Road Junction. Our secretly camera-instrumented traffic dodger is not waiting the ASL we paid our tax money for, apparently because "you get run over by buses turning left on the left turn light, or buses turning right"

• At 0:04 a car parked with its hazard lights on, some L-plate vehicle, we believe.
• At 0:08 the tax-dodger pulls up to go straight on, even though there are no markings on the road to indicate that this is permitted.
• At 1:23 in this dull video (and people wonder why we text in our cars at junctions. This is why), a bus turns right.
• At 1:27, behind the camera, the bus comes to a halt, as it cannot get past the parked car, not with the queue of cars waiting to turn right.
• At 1:31 someone sounds their horn. We are not sure who. Either its the silver car behind the bus, or a car behind the bicycle complaining that they are in the way.
• At 1:40 there are now five cars behind the bus, the traffic speed has been reduced to 0 km/h. No pedestrians will get hit by cars now.
• At 1:46 the green light reaches Shaldon Road, the tax-dodger pedals forward through a junction that is now blocked by stationary cars. Any cars behind them will not be moving, hence their speed is also 0 km/h: again, safety at work.
• At 1:50 the known subversive weaves their way through the now traffic-calmed junction, so ensuring that if there were any pedestrians in Station Lane, they would not get run over by a speeding cyclist.

There we have it then. A single L-plated car can traffic calm a busy junction, reducing vehicle speeds by 15 km/h, that is, from 15 km/h to 0 km/h.

This shows how the addition of extra parking spaces can calm hazardous junctions, and is not merely an attempt by a group of self-centred Clifton residents to add extra parking for their extra vehicles. Although that is, of course, a side-benefit, one that other traffic calming ideas: bike parking, trees and build-outs don't over, which is why it is the only form of traffic calming that we, the Bristol Traffic team approve of.
Update: added the video

AA supporting driver safety

There is lots of coverage today in the cycling world that the AA is giving out free helmets and hi-viz tops, to reduce the risk of them being run over as they ride their Boris Bikes around.

Some people are dismissive of this, implying that the AA is doing a publicity stunt that is really a form of blaming-the-victim. Not at all.

The AA is equally concerned about the safety of motorists. Look here, in the junction of Cheltenham Road and Arley Hill at 18:11 on a weekday evening. This van OU10FYG is stationary in the middle of the junction, held up by the vehicles in front; the cars coming up from Bath Buildings or Arley Hill are at risk of running into the van, given that they have both had green lights while this van is busy blocking the junction.

The hi-viz top the driver is wearing will reduce this risk, as it will be easier for cars crossing the junction to see the vehicle blocking the do-not-enter junction, so the driver will be safer. And presumably the AA's insurance costs will be reduced accordingly.

Roundabout work #2: 08:17

Once the mercedes that blocked vehicles getting off the roundabout had cleared it, vehicles wanting to get onto St Michael's Hill could pull out, and here see the correct tactic: stop cars getting onto the roundabout. It's the only way to reduce demand, and so ensure the junction clears.

Which vehicle do we see here? Yes, its YA55VDY, the cult van of Bristol Traffic

Notice how the vehicle following this car is also in the mini-roundabout, but it hangs back to actually allow pedestrians to cross at the traffic island. Of course, this will prevent vehicles turning right to pull out, which is a bit selfish, but it does allow the roundabout to clear by reducing vehicle ingress rates to match that of egress rates.

The key point here is that it shows that those fellow-motorist-activist groups who advocate removing traffic lights are either missing the point or hiding the truth. On a junction without lights -like this one- the only way to get through is to be aggressive: drive the big vehicles, the 4x4, or even better, the battered big-vehicle, such as the white van. Now we, as  white-van drivers, are happy with this, but we think the harsh truth should be discussed in the open, not discovered once they remove lights from the city centre: whoever values their vehicle least wins.

Roundabout work #1: 08:15

08:15 to 08:16 on the top of St Michael's Hill.

First a car with a Montpelier-MOT wingmirror duct-taped into place. Someone just horned it as to get to this part of the junction (see on the dashed lines) it had to sprint up the oncoming traffic lane.

But by doing so it gets to pull out where the mercedes stuck in the middle of the mini roundabout has left a gap, follow the van through to the right and hope that there isn't anyone crossing the zebra crossing, which would block up the roundabout some more.

It does clear, the gap allows a car coming up Cotham Hill to pull out and turn right into St Michael's Hill.

Or it would, if the Mercedes hadn't stayed where it was.

Do you see what's wrong here? By staying back on the mini roundabout, by allowing cars out of Cotham Road, the school-run-driver is, sadly, making things worse. All the vehicles who are held up on Cotham Hill will see this and drive more considerately.
