The rear-view camera at the vehicle's backside is equipped for parking supports display system. It requires a wide-angle lens for obtaining a broad landscape. Throughout the wide-angel lens, an input picture is converted the Barrel distortion. Therefore, a driver cannot make out the distorted input picture in order to overlay the track directly. In this paper, we propose the generation automatic guideline...
This paper presents an implementation of a Fuzzy Motion Controller (FMC) to endow the mobile robot Robucar with capability to achieve the action behavior allowing smooth motion generation with intelligence in real-time. The robot state space (velocity and distances) is modeled in discrete intervals leading to linguistic variables. The fuzzy motion control rules are derived and used in a fuzzy inference...
This paper presents examines the design of controllers that is computationally efficient yet demonstrates highly competitive performance for a real time simulated car racing game. Algorithms that require large amount of computational resources are impractical for fast paced and real time games (i.e. racing games, sports simulators, first person shooters and real time strategy games). This paper examines...
In this paper, a dynamic multiparameter ant algorithm based route selection system is proposed. This system finds optimum multiparameter route between two desired points, origin and destination (O/D). This method recognizes routes according to user desired parameters in two traffic information availability (online/offline) modes. In the online mode, routes traffic conditions are supplied by a traffic...
The distribution of finished products from depots to customers is a practical and challenging problem in logistics management. Better routing and scheduling decisions can result in higher level of customer satisfaction. The distribution problem is generally formulated as the vehicle routing problem (VRP). Nevertheless, there is a rigid assumption that there is only one depot. In cases, for instance,...
The capacitated vehicle routing problem (CVRP) is one of the most important problems in the optimization of distribution networks. The objective of CVRP, known demands on the cost of originating and terminating at a delivery depot, is to determine the optimal set of routes for a set of vehicles to deliver customers. CVRP is known to be NP-hard problem, and then it is difficult to solve this problem...
The automatic recognition of vehicle type plays an important role in traffic management and automatic toll collection. The research of the recognition mainly focuses on the application of fuzzy theory and neural network theory at present. This paper presents a method which applies extension set and dependent function to process the characteristic data of vehicle. The method can identify common cars,...
Task allocation plays an important role in unmanned combat aerial vehiclespsila (UCAVs) cooperative control. In order to solve the problem of multiple UCAVspsila cooperative task allocation, an improved ant colony algorithm (ACA) is proposed. On the basis of modeling cooperative multiple task assignment problem, the application of improved ACA is discussed. Cooperative task allocation for UCAVs shows...
This paper analyzes the influence factors of sub-zone combined and separated in adaptive traffic signal control system and attempts to fix quantify influence factors that act as the performance indices. Then analyzes the intersections correlation coefficient confirms the ideal state and negative state of sub-zonepsilas combined and separated. Collect VISSIM data as datum mark to compute adjacent intersectionpsilas...
Global positioning system (GPS) resolves railway vehicles location most of the operation time. But what happens when those vehicles are near to critical points, as rail track changes, where more precision is needed? This paper presents a possible solution using inertial sensors and neural networks to find out patterns of railway changes among the inertial sensors' signal. The main objective of this...
The purpose of this research is to develop an effective task assignment algorithm for multiple unmanned underwater vehicles (UUVs) to reacquaint multiple targets. This algorithm is specifically designed for the underwater environment where vehicles typically have dissimilar starting and ending locations. Besides the objective of minimizing the total distance of multiple vehicles, the objectives of...
This paper introduces a new wireless networking approach to multiparameter vehicle navigation systems based on ant algorithm. The proposed system finds the optimum multiparameter route between a pair of origin and destination (O/D). The importance rate of each parameter is adjustable by the user. This system acquires traffic data in online and offline modes. In online mode, traffic data are available...
Recent advances in wireless communications and micro-electro-mechanical systems have fostered the development of wireless sensor networks (WSNs) which consist of tiny, low-cost and low-power sensor nodes. Individual sensor nodes only have local views of the environment, but global views can be obtained by collaborative processing between densely deployed sensor nodes. Energy efficiency is critical...
This paper describes a learning routing system designed to ease the movement of emergency vehicles through a network of congested streets. Real-time capabilities of the routing system are given by the use of GPS equipment installed aboard of every emergency vehicle. The same type of equipment is used to control the state of traffic lights and to collect real-time data on the current traffic volume...
The utility of automatic systems to visually identify vehicles based on the recognition of their license plates is nowadays unquestionable. They can be applied in very different scenarios, like access control, calculation of parking fares, automatic payment of tolls or parking fines, traffic control, etc. In the literature numerous works can be found proposing solutions to the automatic license plate...
