Switzerland’s road maintenance authority has developed an ingenious mobile bridge that allows the paving of public roads without the need to stop traffic on the affected lanes.

Traffic jams are a necessary evil when it comes to road maintenance, and despite experts’ best efforts to come up with a solution to this logistic problem, motorists still have to deal with them whenever road work is required. However, Switzerland’s Federal Roads Office may have come up with an ingenious-enough solution to revolutionize road paving. Earlier this year, it unveiled the Astra Bridge, a 257-meter-long mobile bridge that allows traffic to pass over sections of road while infrastructure is being repaired below. It’s such a simple concept that it almost makes you wonder why engineers took so long to invent it, but there is a reason why the Astra Bridge is the first of its kind – it’s not as simple as it sounds.

German artist Simon Weckert recently went viral after posting a video on YouTube dragging a small cart with 99 smartphones on an empty street and tricking Google Maps into showing a traffic jam.

Basically, Weckert loaded 99 smartphones with Google Maps turned on onto a small wagon cart and then pulled that cart around various streets in Berlin, including outside the Google office building. He was thus reportedly able to fool Google’s GPS app into thinking that there was a high concentration of users on those streets. And because the phones were being carried in a slow-moving cart, the app was also tricked into thinking that it was detecting a traffic jam.

It’s hard to picture a superhero on a cycle, but after watching self-styled ‘Traffic Droid’ a.k.a. Lewis Dediare in action, I have to admit it’s actually doable. Dressed from head to foot in black lycra, with seven video cameras mounted on his cycling helmet, Lewis rides around the streets of London with a single mission – to fight a ‘war of attrition’. You see, the man has taken it upon himself to rid the streets of ‘idiot’ drivers who are a threat to cyclists like himself.

Among the 39-year-old’s other weapons are a camera mounted on a three-foot pole protruding from his bicycle, and a measuring tape. The tape is used to measure the distance that larger vehicles maintain from him on the streets. If it’s anything different from the prescribed amount, he admonishes the drivers and shows them a ‘red card’.

If you plan to visit Vietnam, prepare to forget everything you ever learned about crossing the street. Forget about waiting for the traffic to stop, forget about zebra crossings, and forget about traffic lights. Because in Vietnam, people cross the street by charging right ahead, weaving their way through moving traffic. It’s the only way to do it!

It sounds dangerous, I agree, but it also seems kind of fun, in an adrenalin-pumping kind of way. I’ve just spent the past hour reading about how it’s done. This is from a Vietnam Travel & Living Guide: “You want to get to the other end of the street but it does not look quite feasible. Unless you try it. Crossing over the jam is actually not that bad. You will just have to do it. The magic is that no one will ever run into you.”

I watched a few videos as well; it really does seem like magic. The streets are filled with moving scooters and cars, and the pedestrians just flit across effortlessly. They seem to maintain an intense focus on the oncoming vehicles, finding gaps and moving through them slowly but steadily. There’s just no other way, given the fact that traffic is a nightmare in major Vietnamese cities like Hanoi or Ho Chi Minh.

Usually, it’s the drivers who help out hitchhikers by offering them a ride, but in Indonesia’s capital city, it’s the other way around. Professional hitchhikers get paid to ride in complete strangers’ cars and help them reach their destination faster.

The world’s sixth largest metropolis, Jakarta has a population of over 30 million and around 20 million registered cars. Unfortunately, its infrastructure is far less advanced than that of other large cities like New York, Tokyo or Singapore, which means traffic is terrible. In order to ease jams, authorities have created “Three in One” zones which can only be accessed by vehicles carrying at least three passengers. The measure was successful to some extent, only it also spawned a whole new industry – professional hitchhiking. Every morning, poor Indonesians from the outskirts of Jakarta can be seen lining the sidewalks near entry points to Three in One zones, offering themselves to commuters in a hurry. They are known as jockeys, and unlike regular hitchhikers, they don’t raise their thumbs up to drivers, but their index finger to signal a jockey working solo, and the extra middle finger to signal a couple, usually a mother and a baby.
