I broke down and finally got a tablet.

Today, while waiting to cross the street, I saw something that should never happen.
Here in BC, at many intersections, there are left turn lanes. In some of them, the traffic light will show a green arrow that gives right of way to those turning left. The crosswalk I was at was one such intersection. And as you might expect, the left turn arrows came on in both directions. However, there were no vehicles in either left turn lane.
Is it not obvious that the above situation leads to unnecessary idling, and therefore wastes energy? I see no reason why it is impossible to put a sensor in a left turn lane that, that while the light is red, detects and counts the cars passing over. Perhaps it could detect cars by pushing down slightly when a set of wheels passes over. This will happen twice per car (once per axle). The cars’ weight could press the sensor down. While not perfect (a semi or other long vehicle with more than two axles would result in an incorrect number of vehicles) this will be a good enough approximation to form a sensor system. The number of cars passing into the left turn lane could then be used to decide whether to activate the arrow the next time the light turns green. This system would prevent unnecessary idling due to unneeded turning arrows, and ought to be relatively simple to implement (a computer could probably do it).
I came across this post at Dispatches from the Culture wars. It got me thinking, and eventually my mind thought about previous predictions of what the 2010’s would be like. This led me to realize that the past is more like the present than you think. Indeed, if you predicted that the world thirty years from now would be exactly like today, you probably wouldn’t do too badly.
To illustrate, let’s pretend that some futurologist, Ima P. Rofet, writing (to use round year numbers) that the year 2010 will be exactly like 1980. Let’s see what predictions our prognosticator would have been correct on (not an exhaustive list):
- Politics and international relations:
- There will be two major political parties in the United States, the Democratic and the Republican. There will be other parties, but only these two will have a realistic chance of taking power.
- Russia will be governed as an authoritarian state.
- Nuclear weapons will never have been used in warfare since Nagasaki.
- The conflict in the Middle East will have been unresolved.
- There will be no peace treaty in Korea.
- There will have been no female president of the United States.
- Oil will give the Middle East disproportionate influence on world affairs.
- Terrorism will influence some countries foreign policy.
- The United Nations will not be a world government.
- Culture and society
- Television, movies, and recorded music will be popular forms of entertainment.
- Classical music will be important in music education and most people will be exposed to it in movie and television soundtracks, but it will only retain niche popularity.
- Most people in the western world will live in cities and suburbs.
- An appreciable number of people will have used marijuana, even if it is nominally illegal.
- Most people will travel by car or airplane and, in densely–populated cities, train or other public transport.
- Many people will live in poverty and lack adequate access to food, water, and medicine.
- Many women will still be oppressed and be second–class citizens, even if they nominally have equal rights with men. (more…)
