The most difficult challenge when it comes to navigating through London has been their street signs. The street signs have been either, challenging or impossible to find. When I have found them, I noticed they were on the ground. When there is heavy foot traffic, these signs cannot be seen until you’re standing in front of them. Another street sign I have not seen are one way signs. When traveling in London, it is a headache trying to remember which direction traffic will be heading. To make it worse, there are a bunch of one way streets that have no signage at all. I have been looking both ways multiple times just to make sure I will not be hit by any of the cars. A solution to these problems would to be have a uniform system for presenting directional information. For instance, using a system similar to the United States, were the signs are always hanging off the ground, and easy to read. In a tourist city, good communication is important for good design.
