Oxford (ex Sydney), books, transport, education, science, mathematics, gamelan. Probably mostly posting about Oxford transport, with the odd book review and some pathological polymathy.

The Little Clarendon Street / Wellington Square development is another example, reducing the public space and changing retail frontage to closed off teaching rooms.

And the university and colleges combining to block the county's Parking Standards for New Developments, without offering any constructive alternative, illustrates a failure to think about transport at any kind of strategic level.

… making a mockery of Oxford University’s purported commitment to Vision Zero. Similarly, much of the college development around the outskirts of Oxford is being pushed through despite the social costs for everyone else in the city.

Low Traffic Neighbourhoods - 'more research need'.. Well from 2022 to 2025, funded by the NIHR, we (& colleagues) did that research. And we have 10(!!) peer reviewed articles so far, with more on the way. Here's a summary of our papers so far (all open access so get reading):

She added: “A lot of the current work is being carried out by Oxfordshire County Council not utility companies. We are asking the County Council to review this week’s disruption to better coordinate their roadworks and use all available tools at their disposal to reduce congestion.”

The Conservatives want more road injuries and slower public transport.

On the main stage at Conservative conference, the shadow transport team is discussing how to “counter” things like 20mph zones and bus lanes. The war on the motorist lives.

Plans have been unveiled for a network of cycle routes linking nearby towns and villages to Oxford, backed by county and city councils – and unusually, the University of Oxford. The Oxford Greenways would connect 200,000 residents to the city on traffic-free paths. oxfordclarion.uk/oxford-green...

The route under the Botley railway bridge has fully opened, so I went down to see how the walking and cycling provision works. Summary: the route under the railway bridge is pretty good, the transitions on either side are terrible for cycling (and not that good for walking).

The sections with fence rather than wall have some extra effective with, with a bit of space for handlebars, and the fence on the southern side has been offset 0.09m towards the carriageway, which is even better.

Apparently the south-side fence is going to be replaced by black fencing as on the north side - I have asked that the offset be retained (or even increased).

At its narrowest, where there is a solid wall under the bridge itself, the cycle track on the south side has an effective width of only 1.36m (0.14m lost to the thermoplastic white divider and 0.5m taken off for the wall, following LTN 1/20 Table 5-3).

So this fails compliance wth LTN 1/20, where the "absolute minimum" width for a cycle track is 1.5m. In practice people can cycle on the footpath side if necessary, just as people walking can use the cycle side - and possibly this would be better if it were formally a 4m wide shared path.

It will be interesting to see how this changes with different levels of congestion and improved user knowledge. (But the wayfinding here needs this to be legible to tourists, visitors, and occasional users.)

[ As an aside, the 120 cycle movements I counted in half an hour is a lot for a Sunday outside term time. It would be good to get some better count data, but it is possible that Botley Rd will now be the busiest of Oxford's arterials (excluding Magdalen Bridge). ]

There were a lot of people cycling on the carriageway rather than using the cycle tracks, and far more eastbound (35%) than westbound (8%). This may be because the start of the cycle track is a lot less easy to see coming from Botley Rd...

There were people cycling "the wrong way", but not that many - 8 out of 120 in thirty minutes of counting. Given the complete lack of signs or marking to indicate that cycling is supposed to be one way, this was less than I expected.

(Note that cycling "the wrong way" here is perfectly legal: in the UK there is no real way to make a cycle track one-way. But the county has put in advisory directional markings elsewhere, so probably should here too.)

The actual routes under the bridge seemed to work pretty well. There were people walking everywhere, and sometimes cycling on the footpath to get around people on the cycle path, and I heard a few bells being sounded, but there didn't seem like much conflict between people walking and cycling.

The problem on the east side is that Frideswide Square doesn’t allocate any space for cycling wanderingdanny.com/oxford/2025/... so there is a complete mess where the separate provision under the railway bridge ends abruptly.

@oxfordclarion.bsky.social heh, can you do piece on Botley bridge road and cycle layouts? Illegible and dangerous. Lots of local chatter about it being a mess. Design by WSP. FOI on who in the local councils signed off would be useful. My prediction, serious accident within 3 months😥 Thank you.

A short thread on “legitimate concerns”. The phrase is used repeatedly by UK government ministers. The Home Secretary is at it again this week. But only ever - as far as I can tell - in one context: people’s response to the arrival of asylum seekers. Please read whole 🧵before responding - thanks

I hadn't ridden a bike in Sydney for fifteen years (and hardly at all before that), but I couldn't resist trying out the new Harbour Bridge ramp. So I took a Lime hire bike and cycled from Waverton station to Taylor Square - about 7km (and $23).

Another thing I wonder about is the cycle track on Wilson St. East of Golden Grove St traffic volumes are very low (there were fewer cars than cycles when I cycled it), so it seems entirely unnecessary to have a cycle track.

Or, looking at this another way, entirely unfair that people cycling get 2 metres of width and motor traffic gets 5.5m (plus all the space for parking). At least the eastern half of Wilson St would work better as a "cycle street". wanderingdanny.com/oxford/2024/...

Moving between Castlereagh St and Prince Alfred Park, for example, or getting from the George St to the Wilson St cycle track. In general, it feels like the major cycle tracks have been "tacked on" to the existing road network, rather than the road network being redesigned to support cycling.

A small suggestion is that the kerbing separating cycle tracks from the main carriageway should be chamfered (on the cycle side) to increase the effective width of the track and reduce the risk of pedal strike. (If no one is manufacturing chamfered kerbing there's a market opportunity.)

Most of the city centre roads have a lot of reasonably fast-moving motor traffic and no cycling infrastructure at all -- not even relatively cheap/easy measures such as advanced stop lines -- making getting to or from the cycle tracks problematic.

The connections between segments of cycle track are also poor, involving sections shared with pedestrians (or even pedestrianised, with "dismount" signs), wayfinding that is difficult or confusing, etc.

It doesn't seem like a problem yet, but some of the tracks will be too narrow if cycling numbers increase. In some places the best way to solve this might be to make them one-way and add a cycle track the other way on the other side of the street. Two metres is an ok width for a one-way track...

In general, getting onto or off the main cycle tracks is not really provided for. This is "addressed" in some places by simply banning cycle left or right turns from the tracks -- or by providing options that involve cycles turning on a dime.

First of all, the major cycle tracks - along Castlereagh St, Wilson St, etc - basically work well. This is hugely better than anything that existed fifteen years ago, and opens up cycling as an option for a much broader range of people and trips.

One major problem is the "red wave" phenomenon I mentioned before, where signal optimisation for motor traffic results in people cycling getting red lights at every junction. (Which contributes to riders jumping red lights, which contributes to anti-cycling sentiment.)

Replying to @dannyyee.bsky.social

The bridge ramp is great, but one design feature seems really poor. The sides of the ramp are flared out, which increases the effective cycling width - handlebars stick out further than wheels. But a handrail has been put in that not only undoes that but goes the other way, sloping inwards!
