A Study of the Capacity Drop Phenomenon at Time-Dependent and Time-Independent Bottlenecks
… the use of emerging technology. The concept of capacity drop can be introduced at time-independent bottlenecks (e.g. freeways) as well as time-dependent bottlenecks (e.g. signalized intersections). While to the author's knowledge no one has attempted to link these phenomena, the research …

Formulations, Issues and Comparison of Car-Following Models
… thesis also attempts to address the question of capacity drop associated with vehicles accelerating from congested conditions. Specifically, the capacity drop proposition is analyzed for the case of a backward recovery (typical of a signalized intersection) and stationary shockwave (typical of a …

Understanding Traffic Congestion Through Multiscale Analysis: Sensor Deployment, Car-Following and Universal Scaling
… for reproducing traffic phenomena such as capacity drop and oscillations. The existing stochastic car-following models provide a flexible framework for capturing traffic instabilities such as stop-and-go waves and capacity drop, but its calibration is challenging due to its stochastic …

Parameter estimation and statistical inference of a two-regime car-following model
… formation and propagation of oscillations, capacity drop in the absence of lane changes, and the concave growth pattern of vehicle speeds along a platoon. The probability density of vehicle positions turns out to be analytical in our model, and therefore parameters can be estimated using …

Optimal Evacuation Plans for Network Flows over Time Considering Congestion
… including level of demand, roadway geometry and capacity, vehicle dynamics, traffic stream composition, and lane changing behavior. Chapter 4 addresses some of the modeling and implementation issues encountered in evacuation planning and presents an improved modeling framework that reduces …

Intermediate vapor bypass: A novel design for mobile heat pump at low ambient temperature
… the energy consumption for the same heating capacity, hence improves drive range largely. More and more EV manufacturers are adopting heat pump systems for cabin comfort heating. A mobile heat pump system using the most widely adopted architecture and the same heat exchangers from the first …
