Siemens Highway Maintenance: Exempt

Who should we see on Fishponds Road one sunny weekday morning but the Siemens traffic light team, working on the pedestrian crossing, having moved on from Muller Road.

While taking this photo of the van BN59YEC, someone up a ladder on the other side of this street started shouting "I'm exempt! I'm exempt!". We don't care! We are here to document the possible, not criticise!

However, his claim raises an interesting thought. As we discussed, it is legal for police to park on zig-zags when on call, but not legal for us to paint "Police" on the front, sides and back of our white van, so that fact is of little use.

However it is not illegal to paint "Siemens" and "Highway Maintenance" on your van. We checked. No laws.

Therefore, anyone with a white van who wants to park where they like should nip out to get their vehicle painted up like this, and then get out their and reclaim the zig-zags! And the pavements!

SCOOTing near Zetland Road

We are too lazy to go there ourselves, but Chris Hutt did our bidding and cycled (sorry, we will beat him soundly later!) to get some pictures of the Zetland Road/Gloucester Road nomination for our anti-bicycle awards. First look how this cyclist is riding without a helmet, and to the left of the designated cycling area.

That said, it is kind of ambiguous what bicycles are meant to do at this give way point? Ride, dismount, or get fined by the police. This is the junction where the police were doing exactly that way back in 2008, and it is still an issue at the local PACT meetings.

The cycling rules are clearer at the junction, where you can see the green light saying it is OK to go forwards and onto the A38, hoping the cars coming off Zetland Road aren't turning left towards Cromwell Road at the time.
Which today, at least one car is. Fortunately the cyclist was slow and did not get in the way, as they rarely have third party insurance, and it would be a complicated argument over liability at this junction. Normally if a car hits a bicycle running a light: the bike's fault. But here, the green light says go. So damage to your front bumper might be something you have to pay for yourself.
What say the council? As part of our anti-bicycle awards, we want to make sure the winning feature is not some transient accident which will shortly be fixed, but is in fact a deliberate design decision, implemented according to the plan. It looks good here.

Here is the answer from Adam Crowther, Head of Traffic Signals. 
"The sequence was changed recently to improve capacity thereby reducing the cycle time and reducing delay to pedestrians. We have also introduced SCOOT to better coordinate the signals.

A right turn filter was installed on Zetland Rd so that when the green man at the bottom of Elton Rd runs traffic from Zetland Rd is allowed to turn right - traffic cannot turn left. When the green man goes out traffic from Zetland Rd is allowed to turn right and left.

Cyclists will therefore only be in conflict with traffic from Zetland Rd that is turning right and they will not be in conflict with traffic turning left from Zetland Rd. Although this sounds a bit pedantic cyclists should remain between the studs - although this is not really a good idea as the opposite pavement is too narrow for shared use. Prior to the changes if cyclists turned right from Elton Rd into Zetland Rd they would have been in conflict with the green man. This indicates that the cycle crossing is essentially there to allow cyclists to go inbound on the Gloucester Rd not right into Zetland Rd.

This was a minor change to signal timings so we did not go to TAA as there seemed little point. I can understand that this is not perfect for cyclists but I do not feel it is particularly unsafe as cyclists have good visibility of right turning traffic and can merge in with it.

Signal priorities/sequence changed signs have been erected around the junction to inform people that the sequence has changed.

Whilst in hindsight it would have been beneficial to inform cycle stakeholders of the proposed changes I do not think we would have changed our proposals in any significant way. There are significant benefits to all users of the junction aside possibly from cyclists from Elton Rd. Buses have seen significant improvement in their reliability and after the changes all buses were running on time between the St James Barton roundabout and this junction. Similarly as the capacity has been improved the cycle time is lower and pedestrians experience less delay. It is also likely that rat running will be reduced over time due to the increased capacity. Cyclists have also benefited on most approaches due to the increased capacity and shorter cycle time. In particular the outbound Gloucester Rd movement receives significantly more green time, this is a movement heavily used by cyclists.

I apologise for not informing the cycle stakeholders but we did not consider this a significant change. The benefits to all road users including cyclists are clear. There are no similar signal phasing changes planned in the near future. Let me know if you need any more info.

Thanks,

Adam"
This is wonderful, the best quote yet from one traffic planner who is clearly on our side.
  1. It manages to ignore the fact that of the destinations of bicycles coming off Elton Road, into-town is the main one, as anyone heading North would stay in Bishopston until later, on account of the bike lane being full of parked cars, and the pavement also being full of parked cars. 
  2. The second option would be up Zetland Road; this is no longer possible as you would cycle across traffic.
  3. It notes that prior to the sequence changes, bicycles on the shared bike/pedestrian light would have been in conflict "Prior to the changes if cyclists turned right from Elton Rd into Zetland Rd they would have been in conflict with the green man." -and uses this as justification for the feature. They really don't think anyone should be using this route except to get to the bike park across the road, or to turn left onto Gloucester Road northbound.
  4. It states that signing that priorities have changed is sufficient cues of the changes "Signal priorities/sequence changed signs have been erected around the junction to inform people that the sequence has changed.". This is subtle, as the signs don't tell bikes that they can now get run over by traffic coming from the right, yet it is enough of a disclaimer "we put signs up" that the council avoids liability.
  5. It argues that bicycles benefit, The benefits to all road users including cyclists are clear., because the cycle time at the junction has decreased. To be explicit, there used to be a longer delay between the period in which it was safe to cross the road, now there is a shorter delay between times you can get run over by passing cars.
  6. It reminds bicycle people that they aren't important "we did not consider this a significant change", while clearly implies that the bus companies are in-loop on these decisions.
  7. Because they didn't bother involving the bicycle people, it is unlikely that anyone bothered to count the volume of bicycle traffic leaving this junction, or their destinations. It is now too late to do so and make defensible accusations of the number of cyclists who are now at risk, because the feature has been rolled out. Nobody will try turning right into Zetland Road; less people will use the junction at all. 
  8. Discouraging people from cycling down the A38 will benefit bus times on a showcase bus route, so bring benefits to FirstBus.
Lovely. The best bits come when you think about cycling city. This contraflow, Elton Road, is the primary route for people from Bishopston, the target cycle city community. This change makes it clear that these people shouldn't think about cycling in, they should use a bus instead. FirstBus 1, bicycle troublemakers 0.

This is a showcase bus route remember? And the council's side of the cycle city funding was to come from dual-counted bus lane improvements as well as s106 building development funds. Which means any costs of this improvement may be something we can bill the bicycles for!
We are hoping to get some feedback from UWE about their feature, to round off the pre-award event. In the meantime, can we thank Redland People for their coverage of our site, but point out that we do not consider ourselves local cyclists. They are missing the point entirely. Yes, some local troublemakers like Chris Hutt may be complaining, but Bristol Traffic? We celebrate the irony of a junction where the police have been fining cyclists for cycling through red lights having the signals changed so that cyclists have to cycle through red lights. We relish even more the delicious thought that not only does this stop anyone from Bishopston, the cycling city target area, wanting to cycle into the city, costs related to this junction may be billable as part of the council's contributions to Cycling City.

If we were cyclists we'd be upset, miffed. Feeling neglected, abandoned and perhaps even disappointed. Maybe even angry. But no, we aren't. We are laughing at the profound difference a bit of signal tweaking can make between making a commute by bike if not pleasant, at least survivable, and making it something where only the brave or the stupid will try and cycle round. We are also over the moon about the implications this has for the council's traffic department, where the cycling officers clearly aren't even involved in these kind of day-to-day decisions, and nor are the councillors.

We shall return to "SCOOT" at some other time, it looks interesting, and have engaged in some discourse with the people at the Transport Research Laboratory on its details. They are not yet scared of us, and are answering politely.

Stokes Croft: Hi Viz is power

Evening on the 'croft. now the line of deck chairs is full of a different shift of traffic engineers, all sporting their Bristol Traffic approved Hi-Viz tops, enjoying the evening sun with a faint hint of FirstBus diesel.

When asked "how did they get their cars onto the pavement without driving the wrong way down a one way road", they said "We have dispensation". Clearly doing a traffic survey not only allows you to park on pavements -seen that before- but drive a car down a one way street, all for the sake of the experiment. This must be a very powerful dispensation.

What could be so powerful as to give the cars HD02OVG and X636FWP the ability to drive and park where they like? For that is a power that everyone in Bristol would love to have.

Only one thing has that power: Hi-Viz tops. Admit it -if they weren't in the shiny yellow, they wouldn't be people in positions of authority, they wouldn't have respect from the population. This is why everyone should embrace the yellow tops -they are the first step to achieving power and influence in this city.

On the gentrification of Stokes Croft

Stokes Croft is in transition.


The PRSC are doing their best, but various other interests are at work. The Council have produced Planning Guidance, and the big boys have moved in. In the rush to 'improve' the area there will be many casualties...

This photo is of The Junction, sadly unmentioned as of cultural importance by the Council in their document, but a vital and lively venue. After a long struggle to survive it's about to close, which will be a great loss to the area, and to Bristol. Anyone got a slush fund for a good cause?


(Aside: For anyone reading this who hasn't been there, it has big black doors and inside it can be very loud. They're the sort of doors that most people would never push open without about 20 mates in tow. The patrons can appear rather intimidating, so it's not really on the tourist agenda. However, push the door, pay a couple quid for a gig and it's one of the most friendly of places you can visit. Anyone is accepted, respected and welcomed - even me. The music is great.)

But what has this to do with traffic?

Well, there have been recent 'improvements' to the Jamaica Street and City Road junctions.

Do they actually make things better? As a law-abiding citizen I can't now get to Brunswick Square from Stokes Croft unless I take a much longer route (2 wheels or 4). A minor inconvenience, perhaps, but a larger carbon footprint (with 4 wheels) or larger thighs (with 2 wheels). I can probably live with this in the name of 'Health and Safety', though.


The real downside, however, is the loss of The Junction. Could it be that by removing the railings - which were the only secure cycle parking in the area - and not replacing them with even one Sheffield stand as part of the 'junction improvement', Bristol's Traffic Engineers are putting The Junction out of business?

As all Traders Associations will tell you: No parking = no trade.

Bollards


Here’s a new addition to Amsterdam since my last visit in 2007. Electronic bollards that can be raised and lowered to control access. They’ve appeared along some central canals and also at the entrance to the pedestrian shopping streets (one wonders if they had a problem with cars driving up them). We could do with some of these in Bristol but it would probably get up the nose of some petrolheads and the Evening Post
