Domination in graphs is an emerging area of research at present and it has applications to several fields such as School bus routing, Computer communication networks, Facility location problems, Locating radar stations problem etc. Recently dominating functions in domination theory have received much attention. The new concepts viz., unidominating functions and total unidominating functions hav...

This research explores the application of archived data from Automated Data Collection Systems (ADCS) to transport planning with a focus on bus passenger travel behavior, including Origin-Destination (OD) inference, using London as a case study. It demonstrates the feasibility and ease of applying trip-chaining to infer bus passenger OD from smart card transactions and Automatic Vehicle Locatio...

Scheduling of a bus transit system must be formulated as an optimization problem, if the level of service to passengers is to be maximized within the available resources. In this paper, we present a formulation of a transit system scheduling problem with the objective of minimizing the overall waiting time of transferring and nontransferring passengers while satisfying a number of resource- and...

Inclement weather conditions affect the behavior of travelers and transportation system operations. Understanding this influence can help improve operational planning schemes for any mode transport, especially buses. One factors that be affected by rainfall is time expended a passenger from moment bus opens its doors until he/she boards bus. This known as boarding lost (BLT); it was first intro...

In this paper, we evaluate the cost of electrification an existing bus network. We propose a family bi-objective mathematical models to demonstrate trade-off between strategic (i.e., battery sizing and locations charging stations) operational decisions degradation). The proposed investigate different policies measure their impacts on overall cost. Battery degradation is estimated by tailored li...

Recently, many studies have tried to find travel patterns to understand citizen’s movement behaviours and improve transportation services based on the big data in public transportation systems. This research introduces a method of discovering and evaluating spatial movement patterns from smart card transaction data of multi-modal transportation networks such as subway and bus. The transaction d...

Voltage instability problems increasing day by day because of demand increase. It is very important to analyze the power system with respect to voltage stability. This paper investigates the voltage stability analysis of Kano 330KV Transmission line. The test system network consisting of 11 buses, 4 generating stations, 4 transmission lines and 1 control centres, Power System Analysis Toolbox (...

Understanding the relationship between short-term subway ridership and its influential factors is crucial to improving the accuracy of short-term subway ridership prediction. Although there has been a growing body of studies on short-term ridership prediction approaches, limited effort is made to investigate the short-term subway ridership prediction considering bus transfer activities and temp...

bus accident is a major health problem for bus drivers.  to identify the risk factors involved in bus accidents and to design a model showing the relation between the risk factors and bus driver’s health status, 219 bus drivers who worked for travel agencies in two areas of west and central iran were enrolled into this study.  we used a questionnaire to gather information regarding both the bus...

serovar isolated from a canal in Louisiana in 1978 revealed it to be identical to that of V. cholerae 01 isolated in 1905 from a pilgrim at the El Tor quarantine station. The two strains are associated with sharply contrasting habitats. Ranges of variation of 5 to 15% in procaryotic 5S rRNA sequences between species are typical; variation within species may be 2% or greater. Because the 5S rRNA...
