The tandem loop with multiple vehicles (TLMV) configuration is proposed as a new and effective alternative for automated guided vehicle systems. The TLMV configuration is useful for a large scale manufacturing environment since it can easily accommodate expansion or upgrade while still being less sensitive to vehicle failure than the tandem loop (single vehicle) configuration. Simulation result...

This paper discusses a single-depot complex vehicle routing problem (SCVRP), of which the conditions are that the total routine shall be the shortest and the biggest marched routine of any single vehicle as well. A single objective model is set up upon these conditions. Accordingly, this paper proposes an improved PSO algorithm (GPSO) combined with the crossover operation of genetic algorithm (...

It is accepted that the activity of the vehicle pedals (i.e., throttle, brake, clutch) reflects the driver's behavior, which is at least partially related to the fuel consumption and vehicle pollutant emissions. This paper presents a solution to estimate the driver activity regardless of the type, model, and year of fabrication of the vehicle. The solution is based on an alternative sensor syst...

post-traumatic stress disorder (ptsd) is a chronic and progressive disorder that occurs after some traumas and accident. injuries and harm to health caused by motor vehicle accidents (mvas) have become an issue of global concern, as mvas are expected to be the third largest contributor to the worldwide burden of disease by the year 2020. chronic ptsd is a common consequence of mva and that it m...

This paper presents a novel approach to the reduction of short-span bridge dynamic responses to heavy vehicle crossing events. The reductions are achieved through adjustment of the vehicle suspension damping coefficient just before the crossing. Given pre-calculations of the response of a vehicle-bridge system to a set of ‘unit’ road disturbances, it is shown that a single optimum damping coeff...

Optimization of on-demand transportation systems and ride-sharing services involves solving a class of complex vehicle routing problems with pickup and delivery with time windows (VRPPDTW). This paper first proposes a new time-discretized multi-commodity network flow model for the VRPPDTW based on the integration of vehicles’ carrying states within space–time transportation networks, so as to a...

Progress in understanding the driver/vehicle interface requires an improved model of driver skill in the steering control task. A possible explanation for driver steering skill involves driver usage of multiple internal models of the vehicle dynamics, where each internal model represents the actual vehicle dynamics within a limited range of the performance envelope of the vehicle. This paper pr...

The Intelligent Transportation System (ITS) provides services related to different modes of transport and traffic management systems with an integration of traffic control centers. Video-Based investigation for traffic surveillance has been a vital part of ITS. The traffic surveillance in urban environment have become more challenging compared to the highways due to various factors like camera ...

This paper studies the vehicle routing and scheduling problem with time windows in the pickup and delivery service for customers via vehicles. After discussing the collaborative pattern of vehicles and defining the isolated customer point, we derive the model and strategy of single-pass multiple vehicle collaborations. And then we propose a heuristic algorithm based on single-pass multiple vehi...
