A Theory Of Travel Decision-Making With Applications For Modeling Active Travel Demand, Patrick Allen Singleton

Dissertations and Theses

The continuing evolution of urban travel patterns and changing policy goals and priorities requires that transportation researchers and practitioners improve their abilities to plan and forecast the demand for travel. Walking and bicycling - the primary forms of active travel - are generating increasing interest for their potential to reduce automobile use, save governmental and consumer costs, and improve personal and social health outcomes. Yet, current transportation planning tools, namely regional travel demand forecasting models, poorly represent these active travel modes, if at all.

More broadly, travel models do an incomplete job of representing the decision-making processes involved in travel …

Study Of Seat-Belt Usage In Nevada & Driver's Performance, Atul Sancheti

UNLV Theses, Dissertations, Professional Papers, and Capstones

According to the Centers for Disease Control (CDC), motor vehicle incidents has been reported to be the leading cause of the accidental deaths in the United States accounting for more than 42,000 deaths every year. Distracted driving and Driving under influence (DUI) are the major contributors to these roadway crashes. Moreover, drivers fatigue and drowsiness behind the wheel is another important factor contributing to the high fatality rate. These factors results in significant decline in the driver's abilities of perception, recognition and vehicle control.

It has also been reported by National Highway Traffic Safety Administration (NHTSA) estimated that about 292,471 …

Performance Comparison Of Design-Build And Construction Manager/General Contractor Highway Projects, Binita Shakya

UNLV Theses, Dissertations, Professional Papers, and Capstones

Researchers have conducted numerous studies comparing project performance of design-bid-build (DBB) and design-build (DB) highway projects. However, little research has been done to compare the performance of DB and construction manager/general contractor (CM/GC) highway projects. Therefore, an exploratory study was conducted to compare the performance of 55 DB and 34 CM/GC highway projects from various States Departments of Transportation (DOTs) in terms of cost, change orders, and construction intensity. The results showed that contract award cost growth was significantly lower in DB projects than in CM/GC projects. In contrast to this, the total cost growth of DB projects was higher …

Performance Measure For Transportation Network: A Study In Travel Time Dynamics, Anuj Nayyar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Arterial Performance Measurement and Monitoring is one of the leading goals of any transportation agency. The complexity of the differences between performance measures is highlighted and the various data collection methodologies are highlighted. A major performance measure that impacts end users and traffic planners is travel time. This study presents defining a mathematical system for modeling travel time. The modeling in real-time is presented and methods are proposed to evaluate it using vehicle trajectories. Also comparative results are presented between the actual sensor data sets and simulated data to study the effectiveness of the system developed.

Estimation Of Travel Time Based On Vehicle-Tracking Models, Anuj Nayyar

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis we study the travel time problem based on the known traffic density model. Using the conservation law, we model the travel time function by a boundary value problem of a non homogeneous linear hyperbolic equation. The equation is transformed into an initial value hyperbolic equation, and the well-posedness of the problem is discussed. The mathematical analysis for both density and travel problems are given. We also derive the analytic solutions for several special cases of traffic density. Numerical schemes are proposed for solving for travel time problem. Several numerical examples are presented and error analysis on the …

Developing A Framework For Determining The Contribution Of Transportation Project To Sustainable Development, Karim Ahmed Abdel Warith

Open Access Dissertations

In the past few years, stakeholders in the transportation industry have been concerned with sustainability. However, transportation decision makers have had difficulty incorporating sustainability into transportation infrastructure decisions. This is mainly attributed to the vagueness of the term. Incorporating sustainability into transportation decision making has been a desire put forth by engineers for that past 10 years. However, with no apparent method of defining sustainability, designers and decision makers have not been able to fulfill this desire.

This investigation attempts to define sustainability in a comprehensive and quantitative manner. The research proposes a new methodology that relies on the objective …

Travelers' Route Choice Behavior In Risky Networks, Hengliang Tian

Open Access Dissertations

The accurate modeling of travelers’ route choice decision making when faced with unreliable (risky) travel times is necessary for the assessment of policies aimed at improving travel time reliability. Two major objectives are studied in this thesis. The first objective is to evaluate the applicability of a process model to route choice under risk where the actual process of decision making is captured. Traditionally, we adopt “as-if” econometric models to predict people’s route choice decisions. The second objective is to investigate travelers’ capability to incorporate future real-time traffic information into their current route choice decision making. Two separate stated preference …

Calibration Of Microscopic Traffic Flow Models Considering All Parameters Simultaneously, Victor Hugo Molano Paz

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study proposes a methodology to calibrate microscopic traffic flow simulation models. The proposed methodology has the capability to calibrate simultaneously all the calibration parameters as well as demand patterns for any network topology. These parameters include global and local parameters as well as driver behavior and vehicle performance parameters; all based on multiple performance measures, such as link counts and speeds. Demand patterns are included in the calibration framework in terms of turning volumes.

A Simultaneous Perturbation Stochastic Approximation (SPSA) algorithm is proposed to search for the vector of the model‟s parameters that minimizes the difference between actual and …

An End To End V.M.T Framework With Controlled V.M.T Tax Rate Using Optimal Feedback Control Technique, Pratik Verma

UNLV Theses, Dissertations, Professional Papers, and Capstones

Vehicle Mile Travel (VMT) is a study related to available alternatives for the road

revenue collection system. As per the demand, the existing Gas/Fuel tax based revenue

collection system is not found an appropriate option in the longer run. Due

to existing system constraints like: no eective tax process for vehicles based on alternative

fuel (e.g. electric vehicles), no eective changes in tax due to economical

ination, and more highway expenditure than generated revenue, an alternative revenue

collection mechanism is required. Hence, the objective is to study an alternative

option in detail, which can address the gaps between required revenue …
