The process of surveying crane runways has been continually refined due to the competitive situation, modern surveying instruments, additional sensors, accessories and evaluation procedures. Guidelines, such as the International Organization for Standardization (ISO) 12488-1, define target values that must be determined by survey. For a crane runway these are for example the span, the position ...

This paper is devoted to the development of a map matching algorithm for a train positioning system. Due to the nonsteerable truck design associated with rail vehicles, rail track curvatures are reasonably small. Consequently, track signatures, such as curves, are difficult to identify using low-cost sensors. The algorithm proposed in this work takes full advantage of the inherited “one-dimensi...

Light Rail Transit (LRT) is a kind of rail vehicle form which includes from modern tramcars to speed transport. These vehicles go on special road, underground, floor or specific altitude. Today the number of active serving LRT systems in 50 countries is more than 400. Moreover, a forceful increase has been expected for next years. It is clear that this growing up has certain reasons. In this st...

In the manufacturing line, there is a material handling system which transfers an item from one machine to other machine. One of the simplest material handling systems is RGV(Rail Guided Vehicle) system. In this system, RGV moves only backward and forward on the guided rail and it executes the job which consists of two location information; 'From location', 'To location'. When the RGV gets a jo...

Every year, more than 400 people are killed in over 1200 accidents at road-rail level crossings in the European Union. Together with tunnels and specific road black spots, level crossings (LC) have been identified as being a particular weak point in road infrastructure, seriously jeopardizing road safety. Safety at LC is a single part of a wider picture of transport safety within the whole tran...

three piece bogies are widely in use by the freight railway services throughout the world. in comparison with the other freight bogies they cost less and are easier to maintain. however, they do not exhibit favorable curving behavior. amongst the methods to improve the bogie performance is the proposal to introduce lateral clearance in the bogies’ axleboxs. in the case of the three piece bogies...

The neglectof the rail sector in Brazil that went on for decades is fortunately being overcome, especially in the metropolitan region of São Paulo, with the subways and monorails, an example to other Brazilian metropolitan regions. The historical disconnection between the passenger transport modals combined with the increasing private vehicle fleet and the lack of investment in mass transit sys...
