Map A shows locations of 39 census tracts, existing bicycle routes, parks and recreational areas, and a recently constructed bikeway along 13th Avenue in downtown Denver, Colorado. Map B shows the same geographic area and census tracts that Map A shows; it also shows the average daily bicycle volume for each census tract classified into 4 categories (310 to 500 trips [n = 4 census tracts], 501 to 1,000 trips [n = 15 census tracts], 1,001 to 1,500 trips [n = 10 census tracts], and 1,501 to 3,022 trips [n = 10 census tracts]) and the percentage change in bicycle volume in each census tract classified into 4 categories (−32% to 0% [n = 21 census tracts), 1% to 30% [n = 14 census tracts], 31% to 60% [n = 1 census tracts], and 61% to 90% [n = 3 census tracts]).
