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

Semantic Consistency and Correctness Verification of Digital Traffic Rules

Lei Wan,Changjun Wang,Daxin Luo,Hang Liu,Sha Ma,Weichao Hu,

Engineering doi: 10.1016/j.eng.2023.04.016

Abstract: The consensus of the automotive industry and traffic management authorities is that autonomous vehiclesmust follow the same traffic laws as human drivers.Using formal or digital methods, natural language traffic rules can be translated into machine languageIn response, we propose a method of formal verification that combines equivalence verification with modelReasonable and reassuring digital traffic rules can be obtained by utilizing the proposed traffic rule
