The paths highlighted above are bike routes that were outlined in the “Low Stress Bike Routes in Tucson” map from Mckisson, 2011. However, this map analyzes those paths based on the route’s characteristics within the criteria of the Low Stress Bicycling Network and Connectivity study (Mekuria, et al., 2012). The routes marked in red have the highest stress level (LTS4). These routes are higher ranked mainly because of the stressfulness of the junctions with arterial streets (marked with red pinpoints) without signalized crosswalks and the requirement of the cyclist to cross multiple lanes of traffic moving at high speeds; thus, creating a barrier in the connectivity pattern. The green signifies the route is intermediate in terms of stress (LTS2). These streets are categorized as LTS2 because they are along residential streets with speed limits no greater than 25 mph. The one characteristic that keeps the LTS2 routes from being LST1 is their lack of a designated strip for solely bicycle use. Without the clear separation of modal users, the street is not organized and therefore, unsafe. The blue paths are routes that are exclusively for non-motorized traffic; thus, categorized as LTS1. Below is the connectivity pattern when only including LTS1 and LTS2 since these are the paths that the majority of the population is likely to utilize rather than the occasional, highly experienced and brave cyclist.
