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: An integrated storm surge modeling and traffic analysis were conducted in this study to assess the effectivenessTraffic data were used to analyze the evacuation traffic patterns.In south-east Florida, evacuation traffic started 4 days before the hurricane’s arrival.hurricane path shifted and eventually landed in south-west Florida, which caused a high level of evacuation trafficOver-evacuation caused Evacuation Traffic Index (ETI) to increase to 200% above normal conditions
