This paper presents experimental results of odometric accuracy tests obtained from the first production model of an innovative mobile robot called “OmniMate.” The OmniMate is an omnidirectional platform that comprises two individually controllable drive units (called “trucks”) that are physically connected by a compliant linkage. The compliant linkage allows relative motion between the two truc...

The effect of trucks on the level of service is determined by considering passenger car equivalents (PCE) of trucks. The current version of Highway Capacity Manual (HCM) uses a single PCE value for all tucks combined. However, the composition of truck traffic varies from location to location; therefore, a single PCE value for all trucks may not correctly represent the impact of truck traffic at...

In this project we investigate the effect of heavy-duty trucks, equipped with different Adaptive Cruise Control (ACC) systems, operating in mixed traffic with manually driven passenger vehicles, on the environment and traffic flow characteristics. The sluggish dynamics of trucks whether manual or ACC that is due to their limited acceleration capabilities filters speed disturbances caused by lea...

The short-term and long-term consequences of whole-body vibration (WBV) have been shown to adversely affect occupational health and safety. Some of these effects can lead to permanent disabilities, especially to muscoskeletal, spinal and gastro-intestinal disorders (Boshuizen and Hulshof1). One of the most common complaints from personnel exposed to high levels of WBV is that of lower back pain...

Motors with rare earth permanent magnets are the most compact and energy efficient in applications. However, their use as traction motors for off-highway vehicles, such mining dump trucks, is challenging not only because of high cost magnets, but also difficulty providing a wide range constant power speed control due to unregulated magnet flux. For this reason, induction remain popular type mot...

Heavy-duty trucks make up only 3% of the on-road vehicle fleet, yet they account for > 7% of vehicle miles traveled in the United States. They also contribute a significant proportion of regulated ambient emissions. Heavy vehicles emit emissions at different rates than passenger vehicles. They may also behave differently on-road, yet may be treated similarly to passenger vehicles in emissions m...

Aim of this study was investigating a truck scheduling problem with uncertainty in both inbound and outbound problems. Scheduling authorities at cross-dock should consider these uncertainties and propose a scheduling & sequencing plan which is robust against these uncertainties. As we know, trucks don’t necessarily assign to receiving or shipping doors and should wait a while till a proper dock...

Each distribution center has a different solution to prepare itself for incoming trucks. Due to different circumstances trucks can arrive earlier or later than anticipated. It is very hard, or maybe even impossible, for distribution centers to predict the actual truck arrival times, when they don’t know anything about the schedules from incoming trucks. A solution for these distribution centers...

The problem of how to coordinate a large fleet of trucks with given itinerary to enable fuel-efficient platooning is considered. Platooning is a promising technology that enables trucks to save significant amounts of fuel by driving close together and thus reducing air drag. A setting is considered in which a fleet of trucks is provided with transport assignments consisting of a start location,...
