User Experience Stack Exchange is a question and answer site for user experience researchers and experts. It's 100% free, no registration required.

Some countries that drive on the left side of the road aren't island countries (although most are; the most notable exception is India). For those countries, how do people laying out roads for drivers deal with switching the side of the road that they drive on? I imagine expecting drivers to simply cross over the middle of the road might cause problems.

Voting to close this because as per the faq "You should only ask practical, answerable questions based on actual problems that you face." This question isn't based on a problem you currently have, and there are loads of different solutions of this, as pointed out by DA01. However, if you have a question specifically about how to get people to switch lanes in one specific case (such as on the border between X and Y country) then that's slightly more on-topic. –  JonW Feb 15 '13 at 11:57
    
@DA01 I had found those myself; I thought the question might be good to put here. Seems like it wasn't. –  Joe Z. Feb 15 '13 at 13:32

In high traffic areas, it is usually done with with bridges that cross over and swap the sides.

This is the Lotus bridge in Macau enter image description here

This is the proposed Pearl River Necklace bridge, which perhaps illustrates the concept the best.

Medium traffic areas are usually done with an intersection that may include traffic lights.

This is the traffic light crossing at the Thai-Lao Friendship Bridge. enter image description here

Very low traffic areas are usually done with signs only.

This is a sign post on the Karakoram Highway over Khunjerab Pass between China and Pakistan

enter image description here

Firstly, this bridge is just a concept so doesn't actually exist. Secondly, this would be an extraordinarily expensive method to use, so all but the most wealthy countries would do so. some countries do use bridges, yes, but this isn't 'the way' it's done, its just one of many ways. –  JonW Feb 15 '13 at 7:15
    
Down-voted due to using sci-fi for evidence. –  dav_i Feb 15 '13 at 9:57
    
@JonW Brigdes are used for high traffic areas, even in poorer places like between Brazil and Guyana. And the image I initially had was the best illustration of how it could be achieved. I have added other illustrations for you now. –  JohnGB Feb 15 '13 at 12:02
