Image-based traffic signal control via world models Research Article

Xingyuan DAI, Chen ZHAO, Xiao WANG, Yisheng LV, Yilun LIN, Fei-Yue WANG

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 12, Pages 1795-1813 doi: 10.1631/FITEE.2200323

Abstract: To this end, an effective prediction model is needed for signal controllers.Then, inspired by a model-based method, DreamerV2, we introduce a novel learning-based .The that describes traffic dynamics in image form is used as an abstract alternative to the trafficon abstract representations of traffic states, and the world model can also predict the impact of differentcontrol behaviors on future traffic conditions.

Traffic services for vehicles: the process from receiving raw probe data to space-time diagrams and theresulting traffic service

Markus AUER, Hubert REHBORN, Sven-Eric MOLZAHN, Micha KOLLER

Frontiers of Engineering Management 2017, Volume 4, Issue 4, Pages 490-497 doi: 10.15302/J-FEM-2017008

Abstract: Today, large quantities of vehicle data (FCD: floating car data) are widely used by traffic service providersto create and broadcast traffic states in road networks.After the matching process, space-time-diagrams are created of the probe data showing traffic situationVarious examples illustrate how traffic service quality depends on the number of matched GPS raw dataTraffic reconstruction is followed by a translation into traffic information messages, which can be sent

Integrating storm surge modeling with traffic data analysis to evaluate the effectiveness of hurricane

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 6, Pages 1301-1316 doi: 10.1007/s11709-021-0765-1

Abstract: The Advanced Circulation (ADCIRC) model was applied to simulate storm tides during the hurricane eventModel validations indicated that simulated pressures, winds, and storm surge compared well with observationsModel simulated storm tides and winds were used to estimate the area affected by Hurricane Irma.moderate storm tides (maximum about 2.5 m) and maximum wind speed about 115 mph were shown in both modelTraffic data were used to analyze the evacuation traffic patterns.
