Barcelona is an interesting case study. The city is currently re-doing some of the city's grid neighborhoods into superblocks. The concept is that for every 9 blocks, the interior roads get shut to traffic save for emergency and service vehicles. Inside, the previously 3-lane streets get transformed into pedestrian avenues with vegetation, play equipment and benches/tables for the residents. The contrast between traffic-filled streets and urban tranquility couldn't be starker. Then there are neighborhoods like Gracia that largely closed off its streets to traffic. Going there is like escaping to a village within the city. Finally, the city puts a huge effort into building dedicated bike lanes, usually at the expense of a car lane. They're also rolling out a new shared biking system, which will combine electric and traditional bikes in the same system. It helps that the city has mild winters and 300+ days of sunshine a year, but in any case, they're definitely leading the way for large urban areas to give the city back the people.
