Advancement of mobile technologies has enabled economical collection,\nstorage, processing, and sharing of traffic data. These data are made\naccessible to intended users through various application program interfaces\n(API) and can be used to recognize and mitigate congestion in real time. In\nthis paper, quantitative (time of arrival) and qualitative (color-coded\ncongestion levels) data were acquired from the Google traffic APIs. New\nparameters that reflect heterogeneous traffic conditions were defined and\nut…
