A stochastic mesoscopic cell-transmission model for operational analysis of large-scale transportation networks
The cell transmission model (CTM), developed by Daganzo in 1994 was not fully exploited as an operations model for analysis of large-scale traffic networks. Because of its macroscopic / mesoscopic features, CTM offers calibration and computational advantages over microscopic models. This study …

Link State Relationships under Incident Conditions: Using a CTM-based Dynamic Traffic Assignment Model
… equilibrium Dynamic Traffic Assignment (DTA) model that incorporates the Cell Transmission Model (CTM) to evaluate the temporal variation of flow and density over links, which reflect the link states of a transportation network. Encapsulation of the CTM equips the model with the capability of …

A Macroscopic Model for Evaluating the Impact of Emergency Vehicle Signla Preemption on Traffic
… done using field studies. None of the simulation models that are currently commercially available have the capability to model the presence of EVs and simulate the traffic dynamics of the vehicles surrounding them. This study presents a macroscopic traffic model for examining the effect of signal …

Network Models In Evacuation Planning
… the development and analysis of optimization models for evacuation planning. Specifically we consider the cases of large-scale regional evacuation using household vehicles and hospital evacuation. Since it is difficult to estimate the exact number of people evacuating, we first consider the …

Traffic State Estimation with Multi-Agent Simulations
… einen ganzen Tag. Eine gleichgewichtsbasierte Modellierungsannahme ist ebenso zulässig wie ein Telematikmodell unvollständig informierter Fahrer. Die Verwendung aggregierter Sensordaten zur disaggregierten Verhaltensschätzung wird durch eine kombinierte mikroskopische/makroskopische …

Optimal Evacuation Plans for Network Flows over Time Considering Congestion
This dissertation seeks to advance the modeling of network flows over time for the purposes of improving evacuation planning. The devastation created by Hurricanes Katrina and Rita along the Gulf Coast of the United States in 2005 have recently emphasized the need to improve evacuation modeling and …

Resilient operations of smart highways : platooning, ramp metering, and incident management
… operations under a broad range of disruptions, modeled as stochastic perturbations in highway capacity or traffic demand. In particular, we focus on three types of highway operations: vehicle platooning, ramp metering, and capacity-aware routing/demand management. Our approach relies on (i) …
