Fig. 4: Jam patterns of tree cost during the day can be considered as the city jam-prints of urban traffic.
From: Unveiling city jam-prints of urban traffic based on jam patterns
The temporal evolution of the exponent of the cost distribution of jam trees during the day is shown, in 5 different cities a Beijing (over 17 days), b Shenzhen (over 17 days), c Shanghai (over 5 days), d Hangzhou (over 5 days) and e Jinan (over 5 days). The numbers in the figures are the mean and standard deviation of daily exponents at three typical time windows (20 min for each) indicated by dash lines, at 8:00AM and 18:00PM for rush hours (red) and at 12:00 for non-rush hours (green).
