Road traffic information is the basis of road traffic management and control. Due to the special design of the sensor coil and ferromagnetic core, traffic survey system which uses micro ferromagnetic inductive coil vehicle detector, not only has the features of small size, simple installation and little road surface damage, but also has the advantages of output signal strength, simple signal pr...

The present era has witnessed tremendous growth of the Internet and various applications that are supported by it. There is an enormous pressure on Internet Service Providers (ISPs) to make available adequate services for the traffics like VoIP and Video on demand. Since the resources like computing power, bandwidth etc. are limited, the traffic needs to be engineered to properly exploit them. ...

Given the well-known difficulties in defining and detecting fatigue, it is a real challenge to incorporate it into either traffic or criminal law. Finnish traffic law forbids fatigued driving "only" on a general level concerning the driver's fitness to drive. We present several comments from Finnish traffic and local police officers regarding their own experiences of driving while fatigued. The...

During the last decades, the total number of vehicles around the world growing enormously. Therefore the focus of manufactures, researchers and government is shifting towards improving the on road safety rather than improving the quality of the roads. The vast development in the wireless technologies emerged a new type of networks, such as Vehicular Ad Hoc Networks (VANETs), which provides comm...

Response-type road roughness measuring systems estimate pavement roughness from correlation equations. Most of these systems recommend to maintain a constant survey speed or to keep the speed within a certain range. But carrying out a survey with this speed constraint may not always be possible due to the existence of traffic control devices and heavy traffic flow. Therefore, these systems may ...
