Then, we can estimate the travel time between nodes in DRM straightforward.10Methodology•ThisstudyappliestheGaussianmixturedistributiontofitthetraveltimedistributionoftheobservedroadbottleneck.•TheGaussianmixturedistributionisconstitutedoftwoGaussiandistributions,whichrepresentstraveltimeinthecongestedstateandthatintheuncongestedstate.0.000.040.080.120.160.200.240501001502002503003504004505005506006507007508008509009501000Probability DensityTravel time (Unit: second)histogramGaussianmixture
