driver fatigue is one of the main causes of road accidents. this study aimed to estimate bus driver fatigue through performance measures in a virtual driving environment. the study was conducted on thirty professional male bus drivers participated in a two-hour drive session. the driver subjective fatigue was assessed by fatigue visual analogue scale (f-vas) on 10 min intervals. at the same tim...

background: due to the lack of proper rail road and air transportation, most commutes in iran are carried out by buses. in most cases, the water in the busses is used for passengers for drinking usage. although this kind of water source has provided convince for the travelers, it could be a great risk in disease outbreak. the aim of this study is to determine the water quality in commuting buse...

One of the problems faced by Bus Transport Systems in India is low occupancy rate. Efforts are being made by Bus Transport Corporations to improve bus occupancy by requesting the public to use buses over other modes of transport. One of the reasons for low occupancy is that a passenger normally does not know the bus scheduling information, and bus-arrival timing information to bus-stops. Trends...

In a large distributed computing environment based on local area networks, such as Ethernet or FDDI ring, system performance may be significantly degraded by a bottleneck at some segment of a particular network. In this study we examine the effect that local bus traffic has on the overall performance of a network. In particular, we studied server access for networks using two interconnect techn...

Background. Bus transit time prediction is to predict how long it takes for a bus to travel from point A to point B. Good prediction helps with urban transportation planning and bus riders’ time planning. Artificial neural networks have been proven to work well in this field. Aim. This project aims to make good travel time predictions for both route and segments of route with the bus GPS data u...

Shared-bus multiprocessors represent a mainstream of accepted and commercially viable computer systems. However, as microprocessors become faster and demand more bandwidth, the already limited scalability of shared-bus decreases even further. As an eeort, not a mutually exclusive but rather a complementary to developing better backplane bus, this paper considers adapting distributed shared-memo...

Urban traffic analysis is crucial for traffic forecasting systems, urban planning and, more recently, various mobile and network applications. In this paper, we analyse urban traffic with network and statistical methods. Our analysis is based on one big bus dataset containing 45 million bus arrival samples in Helsinki. We mainly address following questions: 1. How can we identify the areas that...

In this paper we propose a passenger bus navigation system using Wireless Sensor Network (WSNs). This System comprises of three Units: Bus Station Unit, Bus Unit and Blind Unit. The Blind people on the Bus Station are provided with a Blind Unit. The blind speaks his destination on the microphone provided on the Bus Station Unit. When the desired bus stops at the station for the Blind, then via ...

In chip-multiprocessors (CMP) architecture, the L2 cache is shared by the L1 cache of each processor core, resulting in a high volume of diverse data transfer through the L1-L2 cache bus. High-performance CMP and SoC systems have a significant amount of data transfer between the on-chip L2 cache and the L3 cache of off-chip memory through the power expensive off-chip memory bus. This paper addr...

Transit buses are used by millions of commuters every day, but they emit toxic diesel fumes. In 1988, the U.S. Environmental Protection Agency implemented emission standards for transit buses, which have been continually updated. Yet there is no quantitative evidence of the health benefits from these bus pollution policies due to data constraints and confounding variables. In this study, a quas...
