This paper presents an analysis for measuring performance of asynchronous packet switched hierarchical and multiplc-bus multiprocessor systems. T h e performance was measured using both the analytical and simulation models. The performance measured from the analytical model was found to be very close to the performance measured from the simulation model. The performance of a hierarchical bus sy...

Previous research has provided little insight into factors that influence the probability of bus drivers being at-fault in bus-involved accidents. In this study, an analysis was conducted on accident data compiled by a bus company that include an assessment on whether the bus driver was deemed by the company to hold primary responsibility for accident occurrence. Using a mixed logit modelling a...

In this paper the main objective is to analyze the quality of service of the bus companies operating in the city of Campos, located in the state of Rio de Janeiro, Brazil. This analysis, based on the opinion of the bus customers, will help to determine their degree of satisfaction with the service provided by the bus companies. The result of this assessment shows that the bus customers are disp...

This paper addresses the design and performance analysis of partial-multiple-bus interconnection networks. They are bus architectures that have evolved from multiple-bus structure by dividing buses into groups and reducing bus connections. Their effect is to reduce cost and alleviate arbitration and drive requirements without degrading performance significantly. One such structure, called proce...

Jitter is the variation of latencies, when real-time Intellectual Properties (IPs) are accessing data from the data storages. It is a critical factor for such IPs from the Quality-of-Service (QoS) perspective. Jitter of a real-time IP can be measured by how frequently it experiences the underflows and overflows from its data queue in read mode and write mode, respectively. Such failures critica...

bus rapid transit is an innovative, high capacity, lower cost public transit solution in metropolitan cities. idea is to dedicate lanes for quick and efficient transport of passengers to their destinations. in the present investigation the environmental impact assessment of bus rapid transit  in tehran metropolitan city is brought out. for this purpose bus rapid transit lane no. 10 is investiga...

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...

AVL encompasses a variety of location and communication technologies. Archived AVL (or on-vehicle data recording) uses an onboard computer to record and store bus operation data and upload them to a data tank at a specific time (usually daily); real-time AVL (or offvehicle data recording) sends bus travel and operation data to a central computer in real time (usually at a frequency of 30 s to 5...
