Calibration of Dynamic Traffic Assignment Models
Accurate calibration of demand and supply simulators within a Dynamic Traffic Assignment (DTA) system is critical for the provision of consistent travel information and efficient traffic management. Emerging traffic surveillance devices such as Automatic Vehicle Identification (AVI) technology provide a rich source of disaggregate traffic data. This thesis presents a methodology for calibration...
متن کاملRecursive Approaches for Online Consistency Checking and O-d Demand Updating for Real- Time Dynamic Traffic Assignment Operation
To maintain an internally consistent representation with actual traffic conditions, this paper presents an OD demand consistency checking and updating model for on-line dynamic traffic assignment operation. Both predictive and reactive approaches are proposed to minimize (1) the deviations between simulated states and real-world observations and (2) OD demand adjustment magnitude. The two objec...
متن کاملOff-line Calibration of Dynamic Traffic Assignment Models by
Advances in Intelligent Transportation Systems (ITS) have resulted in the deployment of surveillance systems that automatically collect and store extensive network-wide traffic data. Dynamic Traffic Assignment (DTA) models have also been developed for a variety of dynamic traffic management applications. Such models are designed to estimate and predict the evolution of congestion through detail...
متن کاملLiterature Review of Traffic Assignment: Static and Dynamic
Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...
متن کاملImproving the Convergence of Simulation-based Dynamic Traffic Assignment Methodologies
The ability of simulation-based dynamic traffic assignment (SBDTA) models to produce reliable solutions is crucial for practical applications, particularly for those involving the comparison of modeling results across multiple scenarios. This work reviews, implements and compares novel and existing techniques for finding equilibrium solutions for SBDTA problems, focusing on their convergence pa...
