This paper presents three new systematic approaches for computing coefficient matrices of the Heffron-Phillips multi-machine model (K1, …, K6). The amount of computations needed for conventional and three new approaches are compared by counting number of multiplications and divisions. The advantages of new approaches are: (1) their computation burdens are less than 73 percent of that of convent...

There is ongoing debate over the relative advantages of rail and bus transit investments. Rail critics assert that cities which expand their bus transit systems exhibit better performance than those that expand rail systems. This study examines those claims. It compares public transport performance in U.S. urban areas that expanded rail transit with urban areas that expanded bus transit from th...

-  Power system state estimation is a central component in energy management systems of power system. The goal of state estimation is to determine the system status and power flow of transmission lines. This paper presents an advanced state estimation algorithm based on weighted least square (WLS) criteria by introducing virtual meters. For each bus of network, except slack bus, a virtual meter...

We consider the modelling of urban bus networks in dioid algebras. In particular, we show that their dynamic behavior can be modeled by a Min-Max recursive equation.

Energy consumption is one of the performance issues in multiprocessor design. Apart from being critical for power critical systems, it determines the amount of heat dissipates by the system. That is, as the energy consumption rate reduces heat dissipation reduces. Many research efforts had gone into the different design schemes for reducing multiprocessors’ energy consumption. However, it has b...

We aim at applying dioids algebraic tools to the study of urban bus networks. In particular, we show how they can be used for timetables synthesis.

Objective: to analyze and study the urban public transportation system and ant colony optimization algorithm, and propose the optimal route choice model based on GBAS. Method: theoretical analysis and algorithm analysis. Process: On the basis of detailed analysis of urban public transport system, a public transport network topology model is established, and the combined method of bus station an...

Constructing the data model for public transportation by integrating the spatial and the non-spatial information, is the basis of reasonable plan and effective management of urban public transport. This paper presents a transit data model based on geographic information systems (GIS) technology, which utilizes arc-node networks, and manages the foundational bus data with point, link, polygon an...

This paper aims to present and evaluate the performance of one of the first real-time bus dispatching system in Bangkok, Thailand. The proposed bus dispatching system receives the real-time bus location data from the RFID sensor network. The paper provides the background and brief description of both the hardware and architecture of the RFID sensor network and the real-time bus dispatching syst...
