Few studies have correlated counts of street users to walkability features or tested for temporal variations in use across the day. Trained observers counted street users for four streets that differed in walkability according to the Irvine-Minnesota audit. From 7 am to 7 pm weekdays, across four 2-hour observation periods, all four streets had significant quadratic trends of increasing then decreasing use. Furthermore, the two most walkable streets also showed significant linear increases in users across the day. Part of a street's identity is its temporal activity rhythm, and both walkability and rhythms can inform urban design and renewal.
