<title>Abstract</title> Estimation of the origin--destination (O--D) trip demand matrix plays a key role in travel analysis and transportation planning and operations. Many researchers have developed different O--D matrix estimation methods using traffic counts, which allow simple data collection as opposed to...

Trip destination and mode choice are highly influenced by travelers' perceptions and behaviors; selecting a destination and a vehicle for a trip are two interdependent problems. This paper presents and applies a disaggregate joint model for traveler destination and mode choice. The choice model...

This paper studies the transit network scheduling problem and aims to minimize the waiting time at transfer stations. First, the problem is formulated as a mixed integer programming model that gives the departure times of vehicles in lines so that passengers can transfer between lines at...

The move towards commercialization and privatization has pressured airports to become more productive and competitive. The need to devise an overall (total) productivity measure is increasingly important in airport business. The dissertation made three major research contributions. First, it...

On a typical day, more than 53 million tons of goods valued at about $36 million are moved on the US multimodal transportation network. An efficient freight transportation industry is the key in facilitating the required movement of raw materials and finished products. Among different modes of...

Due to the large scale highway construction and fuel tax reform, the Chinese government is suffering from serious difficulties in the Trunk Highway (TH) management (similar to arterial highways in the US). Most concerns are related to the misappropriation of funds and over-staffing. To solve...

Narrow passageways are a significant source of traffic congestion and delay in transportation networks. With traffic volumes expected to increase significantly in the foreseeable future, the effective management of these passageways is needed to mitigate the undesirable impact of these...

The assignment of aircraft arriving on schedule to available gates is a major issue during the daily airline operations. The Gate Assignment Problem (GAP) is an easily-understood but difficult to solve problem. An important issue in GAP is to minimize the distance a passenger is required to walk...

This paper presents a formulation and two solution methods for a very complex logistical problem in disaster relief management. The problem to be addressed is a large-scale multicommodity, multi-modal network flow problem with time windows. Due to the nature of this problem, the size of the...
