From the mouths of babes

Dad: "Noah, do you know that the school board passed a new rule allowing random searches at the school?"
Noah, 12 years old: "No."
Dad: "It means that teachers can just pull you aside and have you show them everything in your bag and pockets. How do you feel about that?"
Noah: "I’m not doing anything wrong so I guess I’m okay with it."

My heart sank. He gave the scripted answer! The system has him. I think Noah is old enough to read 1984, Brave New World, and Fahrenheit 451. Time to knock the dust of my copies.

Random searches of students passes unanimously

The Knox County School Board voted unanimously to approve random searching of students. The next steps are to have the Law Department issue a legal memorandum then to have a final reading of the policy on November 2nd.

A commenter with good common sense from Volunteer TV’s comments regarding the Knox County School Board wanting to implement random searches in the school (emphasis added):

Posted by: Keri Location: Knoxville on Oct 1, 2008 at 09:46 AM
Are we, as members of a free democracy-protected by a Constitution, going to allow the constitutional rights of our children to be trampled upon? I am as concerned as most citizens about the safety of our children at school, but I am more concerned about the intimidation and conditioning of our children to accept infringements on their rights as American citizens. If we accept policies that not only allow, but encourage the powers that be to randomly search our children, without cause or evidence of wrong doing, how much longer before these policies obscure the rights of every citizen? These children are the future policy makers and leaders of our country and they will lead us based on the manner in which they have been lead. It is time to send a message to our children and the policy makers of our community that we value our Constitutional rights and those who fought and died to secure those rights, far too much to allow anyone, for any reason to strip our children of their liberty.

Quit looking for quick fixes and think about the future. Please.

I read your blogs

More often I am bumping into people who volunteer, "I read your blogs." At first I would blush over, maybe apologize, quickly explain that some writing is fiction or embellished, and ask, "Do you still like me?" Now I perk up, smile, and respond positively and thank them for reading adding that I hope they continue to enjoy the writing.

The statement is "I read your blogs" – plural. So Cathy and I get bunched together (and possibly Tommy, Sarah, Noah, Amy, and a specialty blog or two. Evan cannot spell yet.) Of late, the "I read your blogs" has a followup sentence that is consistently being said by unrelated people, "Cathy writes really well!" It’s subtle, but there’s a message in there! I’ll get better with practice. (Cathy does write really well. Domestic Psychology should be in your feed reader! Links for her: post feed and comment feed)

Safer traffic is with less, not more

Michael Silence has posted that another Oak Ridge camera company (we have many: Ipix (dead), Pips, Perceptics, Aldis, others?) is attaching cameras to traffic lights. The full story is in the Knoxnews. These new cameras are being tested to replace the magnetic strips in the pavement that detect the flow of traffic or vehicles backed up at an intersection. These strips are often the bane of motorcyclists as they sometimes do not get detected and have to sit at a light forever. These cameras might be a good thing! Of course, No Silence Here commenter Joe Lance notes "Chattanooga has invested in a couple of cameras — complete with loudspeakers — that announce to illegal dumpers that they are being photographed." When do cameras cease to be a good thing?

I twitch a bit as we throw up more traffic lights, more signs, more lines on the road, more cameras, cameras, cameras. Traffic engineer Hans Monderman believes signs to be a danger to driving.

To him, they are an admission of failure, a sign – literally – that a road designer somewhere hasn’t done his job. "The trouble with traffic engineers is that when there’s a problem with a road, they always try to add something," Monderman says. "To my mind, it’s much better to remove things." [Source, Wired, Roads Gone Wild]

How does Monderman recommend building better intersections?

  1. Remove signs
  2. Install art
  3. Let lighting illuminate both roadbed and pedestrian areas
  4. Do it in the road (ie, get store fronts and Cafes closer to the road)
  5. Negotiate right-of-way by human interaction instead of signs
  6. Eliminate curbs

Knoxville has re-engeered roads for traffic control.near West High Schoolnear West High School Of course this project is not yet complete and Knoxville hasn’t reported on it at all much less said anything about its success or lack of success. Re-engineering roads for traffic control is not simply about removing lights and putting in traffic circles. It is about not cutting down that tree which seems so close to the road. A road with such an apparent danger causes drivers to be more alert. Re-engineering is about not straightening the roads and letting curves control speed. Re-engineering is about rethinking the paradigm by which we design our roads. I think some direct quotes from the article are in order. My favorite is when Monderman proves that designing without signs and signals works by putting hsi hands behind his back and walking backwards, blindly into traffic.

Monderman is one of the leaders of a new breed of traffic engineer – equal parts urban designer, social scientist, civil engineer, and psychologist. The approach is radically counterintuitive: Build roads that seem dangerous, and they’ll be safer.

He [shows] a favorite intersection he designed. It’s a busy confluence of two busy two-lane roads that handle 20,000 cars a day, plus thousands of bicyclists and pedestrians that doesn’t contain a single traffic signal, road sign, or directional marker, an approach that turns eight decades of traditional traffic thinking on its head. Several years ago, Monderman ripped out all the traffic lights, road markings, and some pedestrian crossings – and in their place created a roundabout, or traffic circle. The circle is remarkable for what it doesn’t contain: signs or signals telling drivers how fast to go, who has the right-of-way, or how to behave. There are no lane markers or curbs separating street and sidewalk, so it’s unclear exactly where the car zone ends and the pedestrian zone begins.

Monderman and I stand in silence by the side of the road a few minutes, watching the stream of motorists, cyclists, and pedestrians make their way through the circle, a giant concrete mixing bowl of transport. Somehow it all works. The drivers slow to gauge the intentions of crossing bicyclists and walkers. Negotiations over right-of-way are made through fleeting eye contact. Remarkably, traffic moves smoothly around the circle with hardly a brake screeching, horn honking, or obscene gesture. "I love it!" Monderman says at last. "Pedestrians and cyclists used to avoid this place, but now, as you see, the cars look out for the cyclists, the cyclists look out for the pedestrians, and everyone looks out for each other. You can’t expect traffic signs and street markings to encourage that sort of behavior. You have to build it into the design of the road."

In West Palm Beach, Florida, planners have redesigned several major streets, removing traffic signals and turn lanes, narrowing the roadbed, and bringing people and cars into much closer contact. The result: slower traffic, fewer accidents, shorter trip times.

In the village of Oosterwolde was once a conventional road junction with traffic lights [which] has been turned into something resembling a public square that mixes cars, pedestrians, and cyclists. About 5,000 cars pass through the square each day, with no serious accidents since the redesign in 1999. "To my mind, there is one crucial test of a design such as this," Monderman says. "Here, I will show you." With that, Monderman tucks his hands behind his back and begins to walk into the square – backward – straight into traffic, without being able to see oncoming vehicles. A stream of motorists, bicyclists, and pedestrians ease around him, instinctively yielding to a man with the courage of his convictions.

Some countries have no traffic controls what-so-ever and still function fine. We can also use traffic calming methods or make our roads play music to control speed.

Update 6/3/08: Knoxviews reports that Oak Ridge is considering red light cameras at the same time The New York Times reports Trolling for Trouble in the Red Light District.

Perhaps a better way to reduce red light running lies in improving the design of the intersection. Studies have shown that extending the duration of the yellow light by just two seconds has significantly decreased the number of red light violations. In Dallas, longer yellows and signs warning motorists of red light cameras have helped reduce the violations so dramatically that the cameras are no longer generating the revenue needed to keep them in operation.

Engineer Roads for Speed Control

Knoxville is pondering the use of automated speed cameras to ticket people who violate the speed limits. I am opposed. I am a treat the problem, not the symptom type of guy. My quality assurance training taught me that if you automate a flawed process, you simply perform that flawed process with greater efficiency.

Florida came up with a solution. I read about it a couple of years ago. (unfortunately, I haven’t been able to find the reference) An architect and civil engineer reduced speed by eliminating traffic controls, removing signs, putting people and trees closer to the road, and narrowing the roads. widening the double yellow narrows the roadThey engineered speed control! It worked. Would you like to try it? Knoxville is engineering roads for speed right now! The roads that connect Kingston Pike to Sutherland passing by West High School are changing to reduce speed. If you turn from Kingston Pike to Forest Glen Dr you will undoubtedly notice that the double yellow widens briefly, the road has some lines painted across it, and some ruts have been carved into the road to audibly warn you to slowdown. These are fairly intangible but work! You cannot help but slow down.

What happens when people get used to the lines and drive fast anyway? Firstly, the faster you drive over the ruts, the more horrid the noise which sounds like you are destroying your tires. Secondly, in addition to the psychological narrowing, the roads are being physically narrowed at the midpoint. With the addition of this median, cars will slow down. Maybe they’ll add a tree! (doubt it)

Why not engineer the roads and use speed cameras? Speed cameras treat the symptom. The symptom is that people are speeding. Physical narrowing of Tobler LnThe problem is that people feel like they are making good time and packing more into their lives by speeding. The truth of the matter is that if you are speeding in a town or city, you may be shaving a minute or two off your commute but due to traffic patterns, and the placement and timing of lights and other traffic controls, your commute does NOT change that dramatically as compared to simply driving the speed limit.

Won’t cameras teach people to slow down? No, cameras work after the fact, catch the wrong people, and cannot identify the driver. They also cannot judge the situation. Safe driving sometimes includes speeding up. Often we try to avoid an accident by slamming on the brakes. It feels natural. Sometimes accidents can be avoided by speeding up and I shouldn’t have to speed a day of my life in court plus fees explaining that to repeal a ticket from a robot. Since speed cameras have their effect after the incident, they in no way prevent tragedy! The camera that send a ticket to a speeding high schooler for speeding from West High to Kingston Pike does not save the life of the child who runs out into the road to get his lost ball. The re-engineered roads, which treat the problem and force the new high school driver to slow his vehicle, give that driver the opportunity to stop in time to save the life of the child running into the road to get his lost ball.

Update: Groovy!

Knoxville Street Views Happening Now

Narration with additional commentary (note: since this was ad libbed I misspoke and called the antenna on top of the car "a satellite" when I intended to say "a satellite uplink" or "satellite antennae): [audio:http://realityme.net/wp-content/uploads/2007/11/knoxvillestreetviewshappeningnow.mp3]

camera carPut your best lawns on! A California company is driving around Knoxville taking pictures of your neighborhood for Google Street Views or a competitor. I saw one of these cars zoom through my cove a few weeks ago and I wasn’t quick enough to strike an interesting pose. Westmoreland Gets on Google MapsI was also unhappy with the state of my lawn and porch but oh well. So, will Google catch you peeing on the side of the road? Getting a ticket? Breaking into a house? Growing pot? Or just showing off your favorite thong? (see also). Concerned about privacy?

Better picture:
Google Streetview Car photographs Knoxville

Update: Confirmed! That is a Google car!

Update: The WebUrbanist presents 10 urban snapshots from Google Street View including one implying that the google camera van ignores traffic blockades. Mashable asks Should Google offer to blur Street View imagery for people requesting privacy? And get my cat off your website! If you are enjoying these links then you will also enjoy http://www.streetviewfun.com/, some bizarre splicing issues, and Wired’s voting system to find the best Street View pictures.

Update: Jon Hickman asks, "Where do you actually see the pictures they take?" I am pretty sure these will show up in Google maps and Google Earth. Mashable suggests that they will be accessible from http://www.googlestreetview.com/ and two others but those domains aren’t live yet. Ah! Here is Google’s video explanation of Street Views and a direct link to where Street Views are available.

Of course Microsoft has Windows Live Street View.
