European cities have found that laying streetcar tracks through streets that have been converted to pedestrian-only works quite well, and Memphis has had success with a similar approach in the U.S. Pedestrians quickly learn to stay clear of the tracks and they are reassured by the fact that they know the trolleys will not deviate from their well-defined path.
