"Drive on the left" was the most
Left driving habits can be traced back to several hundred years ago, about ancient Greece, ancient Egyptian and Roman times, anyway, is that people will wear the sword travel times. Since the 85% -90% of the people are accustomed to using the right hand, if you drive on the right, four-wheel and two coachmen more vulnerable to attack in the opposite direction. Executive spear knight, squire saber cake or anti-farmer, everyone had to be ready to face the sudden attack, which means that the line can be left at the crucial moment to rival a nice hit. Of course, this also means they are more vulnerable to attack from pedestrians. But this is also no foolproof method.
In 1773 the British government introduced the "Common Highway Law" (General Highways Act), to encourage riders, coachman and vegetables to the market trafficking saber pedestrians to keep left. Thus, in the subsequent 1835 "Highway Law" (Highway Act) again emphasized this point, so far, it would be left with the UK expressly provides this land.
However, the situation is slightly different from the rest of the world. For example, the Russian government has realized that their people are more inclined to right line (every day if you have to wear heavy coats, probably would not be so worried about the threat of the sword). So they first about transportation bill is to continue to drive on the right. Pre-revolutionary France also drive on the left, but after the revolution, as part of the reorganization of society, but also the right to travel. Napoleon came to power after also asked the army to conquer other countries when right line, reportedly, this is because Napoleon itself is left-handed, right line make him an advantage: You can disrupt the enemy's heart, can show his extraordinary military strategy, but also angered the British. There are more perfect than this it!
Other people are still kept moving left, but in continental Europe, with the increase of land Jiaotonggongju, left the line started to have problems, so in the next few centuries, European countries are slowly converted to drive on the right.
Jiaotongguize two kinds of "expansion"
At that time, Britain and France were busy all over the world to colonize, these two very different ways to crash together. British colonies, such as Australia, New Zealand, India and the West Indies to retain drive on the left, rather French colony is moving right. The United States were divided into two, the French colonialists stick right away, but new to the UK, the Netherlands, Spain and Portugal while maintaining colonists left running.
However, the emerging two Jiaotonggongju to change this pattern. Late 18th century freight wagon (including wide-wheel wagons) more and more popular, especially in the United States. Such trucks are pulling ahead of two horses side by side. The best position to control these "Hercules" is behind the last horse to the left, so that it can wield the whip with his right hand to control other horses. Because it is the left side of Yu Ma, in order to prevent two staggered wagon wheel bump into each other, the best way is to drive on the right. Carriage where to go, where to go along with people, so right with it becoming more common.
As for China, before 1946, are no uniform regulations. Of Northern right with some parts of southern such as Shanghai, Guangdong is left running. In 1946, the ROC government regulations will be moving right.
Cars drive on the right of the emergence of "left drive" has become a global standard
Start the car design is to arrange a driver sitting in the front part of the car, it was soon found that the driver must be able to observe the middle of the road to get easy driving. In countries where the automobile is an important export industry (the United States, that is you), moving right "left drive" rapidly becoming the world standard, forcing latecomers such as Sweden to abandon the original design follow international trends.
Interestingly, this arrangement is indeed very close southpaw habits, so that their main hand is the left hand that you can not leave the steering wheel. A right-handed driver to open a British cars have to spend a lot of time with the left hand control lever habits while operating the steering wheel with his right hand, so it seems indeed the most secure method.
This can also be seen from the way why British cars still prefer a manual transmission.
Why Chinese train is left with it?
Actually, the reason is simple: China's first railway was built by the British, roadbed, signals, track bed construction standards begin with UK standards. Railway is the long-term use, when many domestic railways are to the left of the standards of conduct, the do modify, input would be great.
In addition, the situation in Japan is also more complex in the history of Japan, the country is left with, in part, of their choice, in part because the British engineers put their railway system is completed it. So engineers is really important which country ah!
