Designing mobile application messages to impact route choice: A survey and simulation study
Fig 8
Boxplots of densities along the short route for the different message designs.
The 25% and 75%-quartiles are represented by the boxes. The thick black line in the box represents the median value. Whiskers do not extend up and down from the box more than 1.5 times the interquartile range (75%-quartile—25%-quartile). Values outside the whiskers are considered as outliers (gray dots). Prior to information, the densities were the highest: the medians were above 1.2ped/m2 (fans: ▪) and some outliers were even above 1.5ped/m2. When a route recommendation was provided, the congestion was alleviated: the densities were lower compared to the setting prior to information. If the message depicts congestion information (boxplots 6–9), the densities were smaller than for message designs in which this component was missing (boxplots 2–5). We observed the largest difference for the fans when we provided congestion information in addition to the arrow and team spirit (compare ♦ and ★).
