Bangkok is widely known for its severe traffic congestion. The Thai government advocates the concept of jobs and housing balance (JHB) as a strategy for reducing traffic congestion in Metropolitan Bangkok. The basic idea is to decentralize the jobs to the neighboring provinces so that the commuters would live closer to their workplaces and thereby alleviate traffic congestion. The main purpose of this research is to examine empirically the effectiveness of JHB in reducing the severity of traffic congestion in the Bangkok Metropolitan Region. For this purpose, three data sets derived from the Bangkok Metropolitan Region Extended City Model (BMR-ECM) were obtained from the Office of the Commission for the Management of Land Traffic and the National Statistical Office of Thailand. Travel time index (TTI) was developed to measure congestion. In addition to JHB, a number of land use variables were included in the analysis. They are population density, school density, and job accessibility index. Multiple regression models of TTI as functions of JHB and other variables were estimated at two geographic scales: subsector and traffic analysis zone (TAZ). The study finds JHB is significant in influencing congestion levels in the Bangkok Metropolitan Region. Other influential factors include the population density, school density, and job accessibility. All of these factors are found to be statistically significant in explaining the variation of traffic congestion at the traffic analysis zone level, but not at the subsector level, however.

As the container traffic at the Port of Savannah is expected to increase, its impacts need to be evaluated to address major concerns regarding the roadway network surrounding the port and the overall operations of the port. A federation of two disparate simulators was created in order to model the impacts of increased container traffic. The Port of Savannah was modeled using Rockwell Arena© and the surrounding roadway network was modeled using PTV VISSIM©. These two simulators operated concurrently and continually provided feedback with one another. The challenges that arose from this combination were largely due to the time structure of the models. Arena© is a discrete event simulator and VISSIM© is a continuous traffic simulator. A basic model, where these two pieces of software could pass information between one another, was initially created as a test bed for methods required to federate the two models. These basic concepts were then applied to a comprehensive model of the Port of Savannah and the surrounding area. This federated modeling approach for the Port of Savannah allowed the analysis to reflect the interaction of behaviors unique to the port and local roadway network. For instance, the federated model successfully captured how delays at the Port of Savannah increased as a result of increased congestion in the surrounding roadway network. It is anticipated that this prototypal model will be a base for future research into the area of federating disparate transportation simulators, as well as aid in the further exploration of a transportation run-time interface.

"In many cities around the world traffic congestion has been increasing faster than can be dealt with by new road construction. To resolve this problem traffic management devices and technology such as ramp meters are increasingly being utilized."--leaf 1. / Masters of Information Technology

Road incidents and incident induced traffic congestions are a big threat to the mobility and safety of our daily life. Timely and accurate incident detection using automated incident detection (AID) systems is essential to effectively tackle incident induced congestion problems and to improve traffic management. The core of an AID system is an incident detection algorithm that interprets real time traffic data and makes decision on incidents. / Literature review of existing AID algorithms and their applications reveals that 1) there is no single freeway algorithm that can fulfil the universality aspect of incident detection which is required by the advanced traffic management systems, and 2) how to achieve the effective and stable arterial road incident detection remains a big issue of AID research. In addition, there exists a strong need for incorporating existing expert traffic knowledge into AID algorithms to enhance incident detection performance. / Thesis (PhDTransportSystemsEngineering)--University of South Australia, 2005.
