This paper presents a Quadtree algorithm which is one of the several possible methods that can be used to store an unknown amount of terrain data. The Quadtree algorithm is often used for visualizing large terrain. The Triangulated Irregular Network (TIN) method has been developed recently but it is difficult to make geographical operations such as neighbor finding, searching, and updating. The purpose...
The capacitated vehicle routing is a combinatorial optimization problem of that has aroused major interest because it is present in critical areas (logistics, transport and other) and it is a problem of considerable difficulty. There are currently several techniques that have been developed to try to solve this problem efficiently. In this paper, we present a solution to this problem based on the...
Recent progress in grid computing concept and its allied application technologies has helped us to device an efficient tool for heavy workload management. Concept of this middleware technology supports to build more and more complex application which can process large real time data set. Mobilization of under utilized resources among the needy processes can easily be carried out with distributed grid...
Millions of road users and pedestrians are killed in traffic accidents each year. The need to increase road safety is one of the major concerns, and the better way to increase safety is to develop systems which are able to automatically drive. The authors have tried to extract the information of sharpness of curves on the road and have presented the system which will provide the intelligent speed...
One of the major objectives of Advanced Traffic Management Systems (ATMS) is to reduce traffic congestion in urban environments by improving the efficiency of utilization of existing infrastructures. Many creative and efficient technologies have been developed over the years. Although, commuters especially drivers take a critical part in containing traffic congestion problems, they are playing a passive...
Several systems have been proposed to merge ontologies for heterogeneous application domains. They give primacy to concepts and roles. In this paper, we describe an algorithm to merge two or more ontologies constructed from a common set of corpus for an application domain by different groups of ontology experts. We give primacy to instances and values to discover mismatch. Our algorithm makes distinction...
This paper discusses the limitation of existing methods of reducing the traffic congestion, where width wise expansion of roadways has got limitations, which leads a solution of vertical expansion only. In considering this aspect, an approach for Multi Layer Superway is suggested in a very comprehensive manner to overcome the problem in the present situation. Multi Layer Superway is the concept in...
Based on introducing the essentiality on the fault diagnosis and fault prognostication on the mainly transmission system of armored vehicle, applying the FHR arithmetic completes modeling and identification of fault prognostication modal of the mainly transmission system of armored vehicle. The concrete modeling process includes the test and pretreatment of test data, the model choice, model parameter...
This paper presents a profile based modeling method for generation of realistic mobility pattern for vehicles. It is assumed the profile of the motion of vehicles has a Gaussian profile with different parameters. A driver, first, selects the source, destination and his path and then, selects a profile accordingly. This paper also addresses the issues of lane changing, overtaking, selection of profile...
The push-type packet compensation protocol using the random slot/code selection method have been proposed and evaluated in the synchronous case. However, it is difficult to synchronize between all users. In this paper, the push-type packet compensation protocol using the random slot/code selection method is evaluated by the computer simulation in the asynchronous case. As the results, the random slot/code...
This paper proposes an iterative learning control approach for the traffic control problem and the objective of control is to derive a proper control signal through iterative learning process to achieve the freeway mainline density tracking task in the presence of unknown but repeated environment and disturbance. The performance of the proposed approach is evaluated based on simulation results on...
In this paper we consider a class of dynamic vehicle routing problems, in which a number of mobile agents in the plane must visit target points generated over time by a stochastic process. It is desired to design motion coordination strategies in order to minimize the expected time between the appearance of a target point and the time it is visited by one of the agents. We cast the problem as a spatial...
The radio frequency identification (RFID) tags are an integral part of lives today, whether realized or not. Thousands of applications are currently using RFID tags and the number is growing. RFID finds its application in fields as diverse as race timing, transportation payments, passports, & animal identification. This paper aims at combining the ubiquitous applicability of RFIDs with high speed...
The automated vehicle recognition is of great importance today in intelligent transportation systems. In the process of the feature extraction of vehicle recognition system, the edge vector must be extracted first. However, there are many regions in an image, and it is difficult to extract the edge vectors of the regions of the image. Therefore a novel edge tracing method based on scan-line of image...
