Traffic management in large networks remains an important challenge in transportation systems. The best approach would be to use existing infrastructure and find a solution to manage the increasing flows of vehicles. Multi-agent systems and autonomous vehicles are today considered as a promising approach to deal with traffic control. In this paper, we propose a two-level decentralized multi-age...

The paper deals with the methods for detection and avoidance of collisions of autonomously moving vehicles utilizing the principles and techniques of multi-agent systems. Three different scenarios are discussed: (i) movement of AGVs in 2D space with fixed trajectories, (ii) movement of autonomous robots in an open 2D space and (iii) collision-free flights of unmanned aerial vehicles. For each c...

The problem of coordinating construction vehicles in formations is tackled using the particle swarm optimization algorithm. Coordinated multi-vehicles are anticipated to outperform single vehicles in terms of economy and flexibility. A possible approach is to apply control theoretic methods to vehicle coordination but this may require complicated system models to be employed. The particle swarm...

The paper presents an agent-based cooperative traffic model implemented as an extension of the Multi-model Open-source Vehicular-traffic SIMulator (MovSim). Connected vehicles dynamics are described from a traffic flow theory standpoint using a bilateral multi-anticipative microscopic model. Then, agent-based concepts allow to influence vehicles dynamics through perception and trust-based mecha...

Multi-UAV systems are safety-critical, and guarantees must be made to ensure no unsafe configurations occur. Hamilton-Jacobi (HJ) reachability is ideal for analyzing such safety-critical systems; however, its direct application is limited to small-scale systems of no more than two vehicles due to an exponentially-scaling computational complexity. Previously, the sequential path planning (SPP) m...

A new method is developed to detect the speed of moving vehicles from two consecutive digital aerial images and a pair of QuickBird (QB) panchromatic and multi-spectral images. Since two consecutive digital aerial images taken by UCD have an 80% overlap, the speed of moving vehicles in the overlap can be detected by the movement between the two images and the time lag (about 3 sec). Firstly, ve...

the current regulated particle metric in vehicle emissions is the total mass, while during last decade interest in number size distribution has increased. various international studies on epidemiology and toxicology have reported the adverse effect of the particle matter on public health. the unece group of experts on pollution and energy (grpe) under particle measurement program (pmp) are unde...

1. Abstract This paper summarizes findings related to dealing with the complexity of the design of vehicles for optimal dynamic performance under various driving scenarios. It describes how the authors and their students have been able to improve various algorithms and approaches over several years and where they stand today. The work reviewed starts with a MonteCarlo-based vehicle design metho...

With the development of advanced information and communication technology, traditional centralized service model alone no longer meets increasing demand data exchange in intelligent transportation systems (ITS). While Internet Vehicles (IoV) technology has been introduced to achieve more ITS, there are still some unsettled issues such as flexibility fault tolerance. The conventional approach fo...
