As you can see from the image above, there is a stark difference between the old city and the grid system. Our apartment is conveniently located exactly on that divide in a neighborhood called "El Raval." For a city that began before the age of automobiles, pedestrian usage was always, and still is, a priority. Nowadays, there is a matrix of pedestrians, automobiles, and bicycles using these streets together, causing interesting interaction. (Please see Nate and Will's pages for their studies on these two aspects of Barcelona's transportation network)
The key to my study is to see how that interaction changes at each of these sites, specifically from a pedestrian's perspective. I will be a part time observer looking in, and part time performer of social experiments. I am curious to see what types of behavior changes I find, if any, as I go through the sequence of sites. Stay tuned for results within the coming months. Patience, all in due time!
