April Fools’ Day traffic.

Although this is not one of my favourite days of the year I must admit that I found rather funny and amusing the following stories with urban traffic themes.

The first one comes from Philadelphia USA. Watch the Mayor announcing the E-lane initiative where pedestrians can walk and use their mobile at the same time safely.

The second one comes from Vancouver Canada where Vancouver Observer online newspaper announces the province's new mandatory pedestrian helmet law. This one if it was on Brisbane Times it would be more believable since Australia has already the mandatory cyclist law.
 

The first really interesting April fools’ day story about traffic and transportation that made world headlines was the Copenhagen’s new subway. It looked as if one of its cars had an accident, and had broken through and surfaced on the square in front of the town hall.

 

April Fools ’ Day presents a great opportunity to draw peoples attention to sustainable mobility and humour is quite an effective way to reach behavioural change.

Parking for disabled

At my work I try to do my best to help disabled people find a parking space that suits them in different parts of the city. Their problems are very well presented in this awarded short film from Greece :

My congratulations to the director Stamos Tsamis.

No parking odd sign.

While discussing parking restriction signs and regulations with my colleagues I realised that European parking signs are a lot different than those in Australia.

Take a look at some of the most common parking signs in Australia:

 

Here, parking signs are more like the USA signs:

In both countries you will find some differences between the different states (and territories).
But in Europe, parking signs are a lot different,. This is how the no parking and no standing sign look like.

Also there are some odd signs. Because of the mixed land uses in city centres and the narrow width road network there are the no parking on odd months and even months signs in Greece that look like this:

Crosstown traffic

You jump in front of my car when you,
you know all the time
Ninty miles an hour, girl, is the speed I drive
You tell me it's alright, you don't mind a little pain
You say you just want me to take you for a drive

You're just like crosstown traffic
So hard to get through to you
Crosstown traffic
I don't need to run over you
Crosstown traffic
All you do is slow me down
And I'm tryin' to get on the other side of town

I'm not the only soul who's accused of hit and run
Tire tracks all across your back
I can, I can see you had your fun
But, darlin' can't you see my signals turn from green to red
And with you I can see a traffic jam straight up ahead

You're just like crosstown traffic
So hard to get through to you
Crosstown traffic
I don't need to run over you
Crosstown traffic
All you do is slow me down
And I got better things on the other side of town

One sign I haven't found in Australia

The above sign is quite common in Europe. Most of the European countries have it and in Greece the official name translates to “Start of residential area marked as traffic calm”. 

In Netherlands is called “woonerf” which is the most used international term from the Dutch words wonen 'reside' + erf 'premises, ground'.

Historically this scheme originates from Holland. The Dutch government developed traffic regulations for woonerfs in 1976, though the first woonerf was built in the city of Delft a decade earlier.

In the UK they have the “Home Zone” sign which is much similar. 

In Australia we have the 10 Km Shared Zone which is a quite different in colours. 

 Maybe we need to rethink about not only the sign design but the sign usage as well.

Road safety: A tale with a dragon with big teeth.

The other day I was discussing some road safety issues and a treatment with the name of “Dragon’s teeth” was mentioned. To tell you the truth it was the first time that I heard of the term so I asked myself “What are Dragon’s teeth?”

By the term Dragon’s teeth in traffic management we mean one of the following three things:

1. Triangular road markings that have been installed at the entry points to all 10,000 school zones across New South Wales up to 32.5 metres at the start of each school zone, to improve road safety for students. The Dragon’s Teeth markings further increase the visibility of school zones for motorists and provide a constant reinforcement to keep to the 40 km/h speed limit around schools.

 

2. Calibrated edge and centre line markings used as a secondary method to check vehicle's speed manually by calculating its speed between them when using a road side speed camera.

3. Road surface mechanical devices used to enforce one way traffic. They are mostly used on private road.

Diverging diamond interchange- Traffic engineering innovation

For this week I will take a break from my commuter thoughts and comments and present a small video that I found with some help from Institute of Transportation Engineers newsletter about Diverging Diamond Interchange (DDI)
Wikipedia defines  diverging diamond interchange as a rare form of diamond interchange in which the two directions of traffic on the non-freeway road cross to the opposite side on both sides of the bridge at the freeway. It is unusual in that it requires traffic on the freeway overpass (or underpass) to briefly drive on the opposite side of the road from what they are accustomed.

For many years traffic engineers were only concerned on how to find ways to reduce congestion and provide better traffic flow. Network capacity was in the heart of their research and providing more lanes and better intersections was a priority. But as years past by, everyone realised that providing more road resulted on ending up with more traffic. So over the last decade the research shifted to network efficiency. One of the latest attempts is this new type of  interchange that was was listed by Popular Science magazine as one of the best innovations in 2009 (engineering category) in "Best of What's New 2009".

A picture is worth a thousand words so this 5.15 minute video is worth almost 7.5 million words (or almost 19 million words depending on video quality). :-)
