This paper focuses on the probabilistic numerical solution of the problems in mining, machine industry and biomechanics. Theory and applications of the Simulation-Based Reliability Assessment (SBRA) method are presented in the solution of the hard rock (ore) disintegration process (i.e. the bit moves into the ore and subsequently disintegrates it, the results are compared with experiments, new ...

Motivated by the field sta routing and scheduling problem of an Austrian infrastructure service provider, which involves the planning of subroutes, we study the truck and trailer routing problem (TTRP) [2]. In the TTRP, two types of customers are considered: customers that can be visited by a truck pulling a trailer (denoted as vehicle customers) and customers that can only be visited by a truc...

Weigh-in-motion (WIM) devices record vehicle axle loads on highways. WIM data include loads, inter-axle spacings, classification, gross weights, length, and travel speed. Pavement design, management, performance studies all require data, directly as a spectrum or indirectly standard axles. In 2016, 132 were operating California’s highway network, one of the densest best-maintained clusters in U...

One common mobile robot design consists of three ‘omniwheels’ arranged at the vertices of an equilateral triangle, with wheel axles aligned with the rays from the center of the triangle to each wheel. Omniwheels, like standard wheels, are driven by the motors in a direction perpendicular to the wheel axle, but unlike standard wheels, can slip in a direction parallel to the axle. Unlike a steere...

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 ...

1 The traffic flow heterogeneity caused by the different car-following dynamics among the different types 2 of vehicles has drawn increasing attention recently. This paper explores the characteristics of the four 3 types of car-truck car-following combinations, car-following-car (CC), car-following-truck (CT), truck4 following-car (TC) and truck-following-truck (TT), and their impacts on traffi...

INTRODUCTION Injuries and fatalities due to large truck and other vehicle crashes have decreased over the last decade, but motor vehicle injuries remain a leading cause of death for both the working and general populations. The present study was undertaken to determine semi truck driver and sleeper berth passenger injury risk in a moving semi truck collision using a matched-pair cohort study. ...

ID: 321 It is believed that increasing truck volumes contribute to traffic congestion, pavement deterioration and crashes due to differences in the physical and operational characteristics of trucks and passenger cars. A 2002 US DOT report showed that the number of crashes involving commercial trucks had increased by 40.3% over the last two decades. Based on Insurance Institute for Highway Safe...

background while cyclists and pedestrians are known to be at significant risk for severe injuries when exposed to road traffic accidents (rta) involving trucks, little is known about rta injury risk for truck drivers. objectives the aim of this study was to analyze the injury severity in truck drivers following rtas. patients and methods our local accident research unit prospectively documented...
