Fig. 3: Changes of travel speed and trip time during peak hours.
From: Big-data empowered traffic signal control could reduce urban carbon emission
Geographic distribution of average speed under BAU scenario (all traffic signals are pretimed) (a), target scenario (all traffic signals are adaptive) (b), and the percent change (c). d Rank of cities by trip time reductions each hour, for top 50 cities, trip time reduction is fitted as a power function of rank; for bottom 50 cities, trip time reduction is fitted as a linear function of rank. The base map is applied without endorsement from GADM data (https://gadm.org/).
