The aim of the article is to analyze impact operation on life cycle assessment city buses with diesel and electric drive using neural networks based source data. Two types two were tested. As a result conducted tests, following optimal values obtained for buses: time, number inspections, daily refueling time or battery charging general efficiency, emissions. adopted criteria are buses. presente...

This study assesses the fire safety risks associated with compressed natural gas (CNG) vehicle systems, comprising primarily a typical school bus and supporting fuel infrastructure. The study determines the sensitivity of the results to variations in component failure rates and consequences of fire events. The components and subsystems that contribute most to fire safety risk are determined. Fi...

Providing signal priority for buses has been proposed as an inexpensive way to improve transit efficiency, productivity and reduce operation costs [1]. Bus signal priority has been implemented in several US cities to improve schedule adherence, reduce transit operation costs, and improve customer ride quality [2]. Current signal priority strategies implemented in various US cities mostly utiliz...

BACKGROUND Commuters are exposed to high concentrations of air pollutants, but little quantitative information is currently available on differences in exposure between different modes of transport, routes, and fuel types. OBJECTIVES The aim of our study was to assess differences in commuters' exposure to traffic-related air pollution related to transport mode, route, and fuel type. METHODS...

One of the alternatives to reduce costs in a power system is the application of distributed generation (DG). Although inherent flexibilities of DG, the point of connection must be carefully chosen in order to avoid any hazardous impact. Normally, this choice is based on loss minimization, improvement of the voltage profile and reduction of the power flows through the lines. The search field of ...

Gossiping is an information dissemination problem in which each node of a communication network has a unique piece of information that must be transmitted to all the other nodes A bus network is a network of processing elements that communicate by sending messages along buses in a sequence of calls We assume that i each node can participate to at most one call at a time ii a node can either rea...

In this work we deal with the perimeter flow control problem of bi-modal urban networks by use of a three-dimensional Macroscopic Fundamental Diagram (3D-MFD). The 3D-MFD relates the accumulation of cars and buses and the outflow (or circulating flow) in a bi-modal traffic network. We assume that the impact of each mode on the traffic flow in the network is different, i.e. each bus can not be c...

Mesh connected computers have become attractive models of computing because of their varied special features. In this paper we consider two variations of the mesh model: 1) a mesh with fixed buses, and 2) a mesh with reconfigurable buses. Both these models have been the subject matter of extensive previous research. We solve numerous important problems related to packet routing, sorting, and se...

Buses are the unsung heroes of public transport in modern cities around the world in high, medium and low income countries. However, the bus system is usually cobbled by poor design which has resulted from poor understanding of how a busThis paper examines the impacts of the interactions between buses, passengers and traffic on bus operations, especially in relation to delays and capacity at bu...

This paper investigates a method for the state estimation of nonlinear systems described by a class of differentialalgebraic equation (DAE) models using the extended Kalman filter. The method involves the use of a transformation from a DAE to ordinary differential equation (ODE). A relevant dynamic power system model using decoupled techniques will be proposed. The estimation technique consists...
