I know both, and completely agree they are hazardous. Even 30 mph would be reckless exactly because of poor visibility. Transit size vans parked on junctions are especially lethal. Leighton Road is as bad. I had a very near miss there a few years ago when a woman in a huge BMW sailed straight across, missing my motorcycle by inches. She completely failed to spot there was a junction at all. My son was less lucky, he had a Golf pull into his path - again he was on a motorcycle - due to a large white van parked on the junction. He fell off trying to avoid the car and had his leg in plaster for 6 weeks.I have lost count of the number of collisions and near misses I have seen at the junction of Coldershaw Road with Oaklands. One guy lost a leg after being hit in the driver's door by another car running the junction. 50 yards down the road there was an amazing accident where Seward Road crosses Oaklands Rd, which involved 5 cars, one ran the junction and hit another, then 3 others managed to run into the wreck. Speed was not an issue, nobody was hurt. It was just 4 total idiots not paying attention, and one unlucky guy who got T-boned who probably wasn't doing anything wrong. None of these accidents would be avoided by a blanket 20mph limit. The roads are all humped so that nobody with any sense can exceed 20mph except momentarily if you don't mind wasting lots of fuel accelerating and braking. And all have humps on the approach to junctions.I just don't see what the point is of posting a 20mph limit that nobody will enforce, when humps already make excess speed pretty much impossible. The signage and regulation will all cost money, and will be ignored by anyone who has a mind to try and go faster. Unless we are saying that LBE has wasted untold amounts of money on humping the entire borough and humps are ineffective.All these things have unintended consequences. There is a great deal of research that shows that inappropriate limits that diverge from the natural limit of a given piece of road, whether too high or too low, actually increase accident rates. Driver attention is already overstretched by far too much signage. Humps cost lives by extending emergency services response times - if you talk to a fireman or ambulance driver they will tell you each hump adds around 10 seconds. I interviewed Lambeth Blue Watch a decade ago and they said they had been on callouts where the extra few minutes delay in reaching a fire 20 or 30 humps away had almost certainly cost a life. They estimated 1 fatality a year in Lambeth, and probably more due to ambulance response delayed by humps. I don't know the police position.Speed just isn't a big factor here. Junction design, worn stop lines and poor signageg, inhibited vision due to parked vehicles, and human stupidity and driver inattention are what need fixing. I'd rather see policy shaped by evidence, and money spent on what works rather than what merely looks like they're trying.
