The real-time detections of road parameters, such as traffic volume, velocity and time occupancy, are essential for ITS. Traditional systems are unable to meet the requirements of deployment convenience, detection accuracy, and overall cost. In this paper, we present the design and implement of a traffic monitoring system based on WSN technology. We describe the systematic architecture design a...

This study examines the relationship between train traffic and the accident risk for road users at level crossings. The marginal effect of train traffic on the accident risk can be used to derive the marginal cost per train passage that is due to level crossing accidents. Based on Swedish data from 2000 to 2012 on level crossing accidents, train volume and crossing characteristics, the marginal...

In recent years, flexible manufacturing system as a response to market demands has been proposed to increase product diversity, optimum utilization of machines andperiods of short-term products.The development of computer systems has provided the ability to build machines with high functionality and the necessary flexibility to perform various operations. However, due to the complexity and the ...

We compare three road classification systems to actual traffic counts in order to assess how well the classification systems perform as indicators of traffic volume, assuming that clear differentiation of traffic volumes among classes is desirable. Actual traffic counts were obtained for 215 locations in the Greater Vancouver Regional District(GVRD); the British Columbia provincial Digital Road...

OVERVIEW: Traffic control systems for automobile traffic are being set up that allow more advanced traffic signal control according to traffic conditions and provide drivers with the real-time traffic information that they need to make their own driving decisions. The traffic information required by the driver includes traffic regulations, degree of congestion, parking space availability and so...

The network traffic matrix is widely used in network operation and management. It is therefore of crucial importance to analyze the components and the structure of the network traffic matrix, for which several mathematical approaches such as Principal Component Analysis (PCA) were proposed. In this paper, we first argue that PCA performs poorly for analyzing traffic matrix that is polluted by l...

Many researches have been investigated on planning or designing WDM networks assuming that the future traffic is known beforehand. Practically, it is difficult to predict the future traffic demand accurately since there are various types of data traffic with different traffic characteristics. In this thesis, we propose a scheme to design a WDM network that will accommodate as much traffic as po...
