The paper introduces a motion simulation, monitoring, and controlling system based on a three-degree-of-freedom (3DOF) motion platform, stereographic display, and network communication. Proportional-integral-derivative (PID) and fuzzy logic (FL) controllers are applied to control the motion platform and to compare their control qualities with each other. Two applications of the present system are demonstrated. One is a car simulator, in which the motion platform simulates the behaviour of a car running on the road. The other one is an animated virtual reality (VR) remote control system. By cooperating with real-time virtual scene reconstruction, users can remotely monitor and control the motion platform in real-time.

A kind of 3-RPS and 3-DOF parallel robotic mechanisms is used as motion-sensible-platform of gun training simulator to implement the motion simulation. Its dynamics is analyzed and driving force of joint is gained. This paper introduces the study on motion generation of gun training simulator. The moving model of gun is established on the basis of the model of vehicle. We solve the pose of gun by applying the theory of homogeneous matrix. In order to ensure actuators moving at a preset speed and enable the motion-sensible-platform to perform a real-time moving posture simulation of a wheeled gun vehicle in running, the speed equation of actuator is given. The feasibility of models was tested through the simulation experiments. All of these works are beneficial to optimize design and control realization of motion platform structure.

Traffic Rules

The traffic controlling system in Bangladesh has not been updated enough with respect to fast improving technology. As a result, traffic rules violation detection and identification of the vehicle has become more difficult as the number of vehicles is increasing day by day. Moreover, controlling traffic is still manual. To solve this problem, the traffic controlling system can be digitalized by a system that consists of two major parts which are traffic rules violation detection and number plate recognition. In this research, these processes are done automatically which is based on machine learning, deep learning, and computer vision technology. Before starting this process, an object on the road is identified through the YOLOv3 algorithm. By using the OpenCV algorithm, traffic rules violation is detected and the vehicle that violated these rules is identified. To recognize the number plate of the vehicle, image acquisition, edge detection, segmentation of characters is done sequentially by using Convolution Neural Network (CNN) in MATLAB background. Among the traffic rules, the following traffic signal is implemented in this research.

In order to solve the problems of traffic object detection, fuzzification, and simplification in real traffic environment, an automatic detection and classification algorithm for roads, vehicles, and pedestrians with multiple traffic objects under the same framework is proposed. We construct the final V view through a considerate U-V view method, which determines the location of the horizon and the initial contour of the road. Road detection results are obtained through error label reclassification, omitting point reassignment, and so an. We propose a peripheral envelope algorithm to determine sources of vehicles and pedestrians on the road. The initial segmentation results are determined by the regional growth of the source point through the minimum neighbor similarity algorithm. Vehicle detection results on the road are confirmed by combining disparity and color energy minimum algorithms with the object window aspect ratio threshold method. A method of multifeature fusion is presented to obtain the pedestrian target area, and the pedestrian detection results on the road are accurately segmented by combining the disparity neighbor similarity and the minimum energy algorithm. The algorithm is tested in three datasets of Enpeda, KITTI, and Daimler; then, the corresponding results prove the efficiency and accuracy of the proposed approach. Meanwhile, the real-time analysis of the algorithm is performed, and the average time efficiency is 13 pfs, which can realize the real-time performance of the detection process.

After briefly pointing out the weakness of participation at the core of the Regional Committees for Economic Expansion (CREE), the author analyses in depth the notion of participation as it has existed in France since the administrative reform of March 14, 1964, within the Commissions of Regional Economic Development (CODER).Having touched on the place occupied by and the role played by these organizations throughout the process of elaboration, execution, and control of the plan at the regional districts level, the author then turns to an examination of the composition and function of these consultative processes.As far as the composition of the CODER is concerned, the article deals with three main features: the tripartite nature of the commissions; the imbalance of forces particularly to the detriment of the trade unions; and the major reforms capable of improving the representativeness of the commission.Regarding the functioning of the CODERs, the author, having described the vast range of duties which are devolved on them by the texts, puts into perspective the extreme weakness of their “powers” in contrast to the unquestionable authority of the regional prefect. Thus, the CODERs are described as bodies directly under prefectorial control, veritable registry offices deeply divided at their centre, without real expertise and without great impact on public opinion.At the end of the study the author recalls the abortive attempt at regional reform on April 27, 1969, and concludes that it will be necessary to set to work on a far-reaching reform in order to get France on the road towards real democratization of the process of regional planning.

The paper aims at introducing an advanced delivery tour planner to support operators in urban delivery operations through a combined approach which chooses delivery bays and delivery time windows while optimizing the delivery routes. After a literature review on tools for the management and the control of the delivery system implemented for optimizing the usage of on-street delivery bays, a prototypical tour delivery planner is described. The tool allows transport and logistics operators to book the delivery bays and to have real-time suggestions on the delivery tour to follow, through the minimization of the total delivery time. Currently, at development phase, the tool has been tested in a target zone, considering the road network and time/city delivering constraints and real-time data about vehicles location, traffic and delivery bay availability. The tool identifies the possible tours based on the delivery preferences, ranks the possible solutions according to the total route time based on information on the road network (i.e. travel time forecasts), performs a further optimization to reduce the total travel times and presents the user the best alternative along with the indications of which delivery bay to use in each delivery stop. The developed prototype is composed by two main parts: a web application that manages communication between the database and the road network simulation, and, an Android mobile App that supports transport and logistic operators in managing their delivering, pre trip and en route, showing and updating routing based on real-time information.

Abstract: In the present era, the population of people living in cities and the number of vehicles on the road is growing by the day. The necessity to govern lanes, thruways, and streets has become a significant concern as the urban population and, as a result, the number of vehicles has grown. Today's traffic framework places minimal emphasis on real-time traffic conditions, resulting in inefficient traffic management systems. Therefore, to overcome such limitations or drawbacks of the present system, the current research proposes a smart and efficient traffic management system that can analyze real-time traffic and take appropriate action. This is achieved by the application of an image processing technique, that would capture the real-time pictures of the paths to compare with the reference image of the path. The evaluation matrix is created to decide the amount of time each light must be on. In addition, an evaluation matrix is created. The purpose of the evaluation matrix is to determine how long each light must be turned on. The MATLAB 7.8 was used to perform the study.

The adaptive headlights use a variable headlight control system geared to the driver's position on the road. Thisanticipative illumination of the road ahead is based on a system of sensors. The adaptive headlights direct two headlightmodules rotated by motors after sensing steering during the ongoing course of the road, offering the driver a better view atthe road ahead both in front and in curves. Adaptive Headlights automatically adjust the light to match the direction oftravel. That enables the driver to react more quickly because he/she will see the road ahead more clearly. Sensorsmonitor steering angles to assure the proper distribution and control of the beam pattern.
