To implement quick and reliable communication between CAN bus network and computer, we propose a sort of design method of CAN bus network adapter based on CH372, and mainly introduce the concrete implementations of hardware circuit and software program in this article. This system adopts the modularization design, and a new USB interface chip CH372 is adopted in the USB communication module, wh...

During a time of budget challenges, the Washington, D.C. government has needed to increase appropriations to the public safety and justice title while reducing appropriations to other municipal services. The need to increase policing costs by $1 million to $469.7 million in fiscal year 2012 diverges from the city’s efforts to improve underserved neighborhoods through urban renewal. Although the...

Reliability is a fundamental factor in the operation of bus transportation systems for the reason that it signifies a straight indicator of the quality of service and operator’s costs. Todays, the application of GPS technology in bus systems provides big data availability, though it brings the difficulties of data preprocessing in a methodical approach. In this study, the principal component an...

Public transport system must be profitable to the private operators without government subsidy or intolerable rise in bus fare to ensure efficient mobility in a third world city. However, a populist but not so affluent government is unwilling either to subsidize or raise the bus fare, thereby forcing private players to withdraw or compromise with the level of service and the commuters are badly...

A new method of load flow analysis of a power system using Particle Swarm Optimization (PSO) trained neural network is proposed in this paper. Load Flow Analysis is the first and foremost step in power system analysis. It is necessary to solve load flow problem for Power System Planning, Contingency analysis, and Stability analysis. The results obtained from the load flow analysis are Voltage m...

Concerned with fuel consumption and emissions, especially public transportation in urban areas, the ELFA electric drive system has been developed for hybrid bus applications. This modular system provides bus manufactures a cost effective solution with a maximum degree of design flexibility. The system is adaptable to buses with a wide variety of energy storage devices, power sources, and hybrid...

This article is the result of a case study on ergonomic work analysis carried out in an urban bus company located in Ilha do Governador, Rio de Janeiro. The methodology used in this work follows the French-tradition Ergonomic Analysis of the Work (EWA) combined with the best tradition from anglo-saxon ergonomic work analysis. The situated diagnosis was performed to provide relevant information ...

background the most accidents can be directly attributed to human factors. hence, more traffic crashes result from driver malfunctioning which from among them, the driver behavior is a proximal factor in the road traffic injuries causation chain. objectives this study aims to investigate relationship between aberrant driving behaviors questionnaire (dbq factors) and self-report crashes involvem...
