Finite element method in pavement analysis is a type of mechanistic analysis that has widely been used by road and transportation engineers these days. This method is used with related programs such as ABAQUS/CAE which is one of the powerful software on this task. Modeling in this software has been developed from 2D static models to 3D dynamic models which are closer to reality due to the more ...

This study evaluates different strategic courses of action concerning the secondary transportation sector in Hyrcanian forests of Iran. The decision support method Analytic Hierarchy Process (AHP) has been utilized in the assessment of different strategies in truck selection. The assessments are based on the opinions of a group of experts in Iranian forest industries. Results showed that the tr...

Non Destructive Testing applied to railway axles is performed both in production and in maintenance. During production, NDT is carried out at different stages adopting different techniques, while during maintenance (in-service inspection) only ultrasonic testing is usually carried out. The present paper is focused on some aspects of calibration related to the in-service inspection of railway ax...

Bridge Weigh-in-Motion systems can be used to estimate vehicle parameters such as velocity, axle loads, or the distance between axles without affecting the traffic. These parameters and the classification of vehicles are necessary to determine vehicle overload and hence may help to reduce risks for road users and road infrastructure and allow optimized planning of maintenance work. The Bridge W...

The toll rate charged for the usage of facilities such as a tunnel or a bridge is usually proportional to the number of axles possessed by a vehicle. However, it is sometimes difficult to determine the number of axles of a vehicle by the toll-booth operator and therefore, an automatic system that can identify the number of axles is sought. Instead of detecting the axle, wheels of a vehicle are ...

In contrast to conventional internal combustion engine driven vehicles, the number of motors in fully electric cars is not fixed. A variety of architectural solutions, including from one to four individually controlled electric drive units, is possible and opens up new avenues in the design of vehicle characteristics. In particular, individual control of multiple electric powertrains promises t...

In view this, present study sought evaluate impact average cost transportation price Sul adoption practice collaborative logistics as an alternative reduce costs. order calculate tr...

EA4T steel has been widely used in the manufacture of railway axles. Laser cladding remanufacturing technology to repair axles, and failure behaviors axles studied. In this work, a class original FeCrNiMo alloy layers that contain rare-earth elements was successfully fabricated through laser technique on substrates. The microstructure elemental distribution were analyzed scanning electron micro...
