In April 2012 I joined 10,000 soggy cyclists in the rain to call for a big change to our streets, so whoever won the imminent Mayoral elections would ensure our streets would be safe and pleasant for cycling. In response to months of fantastic campaigning, and not wanting all the cycling votes going to the Green Party, Boris Johnson duly signed up, telling cyclists: “I am fully committed to meeting the three key tests of LCC’s ‘Love London, Go Dutch’ campaign”. Eight months later, TfL began to consult on the plans for Cycle Superhighway 5, from New Cross Gate to Victoria via Peckham, Camberwell and Oval. Here was a golden opportunity for Boris to “make sure all planned developments on are completed to Go Dutch standards, especially junctions”, one of those three key tests he signed up to. Months of consultation and roadworks later, this is what we got: Does…

One of my top priorities for the Crystal Palace and Anerley area would have to be traffic reduction. Every day on my way home from work, walking back from the station or cycling down the hill, this is what I see: The crawling queues are similar around the Triangle and down the other main roads in the area. This is bad news, if only because it’s annoying to be stuck in traffic! Plus, it snarls up buses and makes them less reliable. Here is another pair of pictures, this time showing air pollution in the area. The map on the left shows the quantity of deadly nitrogen dioxide emitted by vehicles each day, and in case you’re wondering the dark blue along Crystal Palace Parade is about the same as the Strand in central London, while the pollution down Anerley Hill is similar to that on the roads leading north…

I’m supporting the Space4Cycling campaign in the Crystal Palace ward, where I’m standing for the Green Party. I often cycle up and down Anerley Hill on the way to work. It’s a steep bit of road, difficult for those of us who aren’t zipping up to Cadence every weekend on expensive road bikes. Cycling uphill without wavering a little is hard work, so providing some protected space at the expense of a little car parking makes perfect sense. Of course some people who currently park their cars there will lose out. But I want to see streets in Crystal Palace, London, the whole of the UK transformed to serve the needs of people on foot, bike and public transport, and this can only happen at the expense of cars because we have limited road space. The alternative is to leave almost 20,000 vehicles a day trundling along Anerley Hill, creating…

One of the odd things about contributing to OpenStreetMap is that you have no idea who is using the maps and the data. You spend hours, weeks, months, years even building up a wonderfully comprehensive database of geographic features in the area, all because it’s fun, because you believe in the project’s ideals or you need the data for your own project. But does anyone else use it? It would be depressing if the answer was “no”. So I get cheered every time I see documents like this: That’s an excerpt from a presentation by Southwark Living Streets. They took the Mayor of London’s transport advisor around Elephant & Castle to show how unfriendly and dangerous the area is for pedestrians, and illustrated the whole thing with OpenStreetMap. The chap who made this loves OSM, he told me he realised how useful it could be when he noticed we had…

While we’re benefiting from all this rain in London, which keeps air pollution at bay, I’ve been wondering about including pollution data in OpenStreetMap-based routing engines. The trouble is that I lack the technical skills to implement this, so I’m writing this post in the hope that somebody might be inspired to give it a go. Air pollution is the second biggest cause of premature deaths in the UK after smoking. Here’s a little league table of nasties taken from Department of Health data: Smoking – 87,000 premature deaths per year Air pollution – 29,000 Alcohol – 22,000 Obesity – 9,000 The main pollutants in cities are particulates (PM10, PM2.5), nitrogen dioxide (NO2) and nitrogen oxide (NO). Unlike the pea souper fogs of years gone by, these are invisible to the human eye but very deadly. They’re most concentrated on busy congested roads and around airports – so unsurprisingly in central London,…

Those who are inclined to compromise can never make a revolution – Kemal Ataturk Every day I set off on my bike for a pleasant three mile commute to work. I love cycling around London, it’s cheap and fun, and I particularly enjoy the spring when lots of “fair weather cyclists” swell our ranks along cycle routes. Much of London is crap to cycle around, but politicians of all colours claim to support a “cycling revolution”. To achieve that, you’d need to make people from all walks of life feel safe – the number one barrier – and make cycling seem pleasant. Southwark Council did an audit of their roads recently and found that it was impossible to get further than a few hundred metres without using a road requiring “advanced” cycling skills. You need to be happy using “busy roads” with “complex junctions and road features” to cycle to…

I’ve started trying to add speed limits data to roads in my patch of Southwark. Two things made me start looking at them… First, I go everywhere by bicycle, which means speed limits and London congestion are of very little relevance to my journey times. But I noticed that journey planners like CloudMade’s offer wildly optimistic journey times for cars. Even ignoring congestion, I thought, they can’t be taking account of speed limits, which across London are lower than the national assumptions. For example, most main roads have a 30 mph speed limit and a growing number of roads, residential and main, have a safer 20 mph limit. The second reason is that speed limits have been a big issue for cyclists recently, featuring in campaigns around issues like Blackfriars Bridge and Southwark’s Transport Strategy. So here’s a snapshot of our data around Peckham and East Dulwich after a few…
