In this dissertation, we study macroscopic traffic flow modeling for intelligent transportation systems. Based on the characteristics of traffic flow evolution, and the requirement to realistically predict and ameliorate traffic flow in high traffic regions, we consider traffic flow modeling for intelligent transportation systems.

Macroscopic models for traffic flow in networks of roads are widely used in analyzing traffic phenomena and for the management and planning of transportation road systems.Calibration of Microscopic Traffic Flow Models Considering all Parameters Simultaneously. by Victor Hugo Molano Paz Dr. Alexander Paz, Examination Committee Chair Assistant Professor Civil and Environmental Engineering University of Nevada, Las Vegas This study proposes a methodology to calibrate microscopic traffic flow simulation models.The objective of this thesis is to analyze the effect of these factors on traffic performance measures on urban roads. To carry out this work, a research design was formulated including specific methods and prescribed limitations.
This dissertation develops a number of model reformulations and efficient solution algorithms to address resource allocation problems in air traffic flow management, while explicitly accounting for equitable objectives in order to encourage further collaborations by different stakeholders.
Traffic congestion challenges traffic flow in urban area and is prevented smooth traffic. A growing urban area creates complex problems in daily life with traffic. Congestion phenomenon’s can not be terminated only by applying physical constructing such as: build bridge, motorways and increasing road capacity.

This dissertation aims to apply a series of intelligent and robust approaches to some of the problems in the classification, simulation and control of traffic flow. At first, the efficient, yet practical, method for the classification of traffic flow states on highways was developed.
Abstract: This dissertation concerns modeling and computation of macroscopic fluid-like traffic flow on a single lane road as well as on multilane, coupled with lane changes. We start with single lane models and consider the scalar model, expressing car mass conservation, proposed in the 1950s (Lighthill-Whitham 1955, Richards 1956).
The traffic flow forecasting is to establish a core technology for traffic guidance system, but also the establishment of the important aspects of the intelligent transportation system. For short term traffic flow forecast, now there are a lot of analysis and research.. Related Dissertations. Feature Extraction, Selection and Combination in.
Abstract. In this dissertation we address a stochastic air traffic flow management problem. This problem arises when airspace congestion is predicted, usually because of a weather disturbance, so that the number of flights passing through a volume of airspace (flow constrained area - FCA) must be reduced.
Land use and its related activities generate and distribute trips between places. Traffic flow analysis is an essential component of a city’s traffic and transport systems since these flows could (and often do) lead to the occurrence of congestion on our roads.
A goal of air traffic flow management is to alleviate projected demand-capacity imbalances at airports and in en route airspace through formulating and applying strategic Traffic Management Initiatives (TMIs). As a new tool in the Federal Aviation Administration's NextGen portfolio, the Collaborative Trajectory Options Programs (CTOP) combines many components from its predecessors and brings.
The goal of this dissertation is three-fold; for starters, we provide a complete nomenclature convention within traffic flow theory, built upon a consistent set of notations. In continuation, we give an in-depth literature survey on the mathematical models used for describing road traffic flows, both from a transportation planning and a flow propagation point of view.
