We consider a large-scale road network in Eastern Massachusetts. Using real traffic data in the form of spatial average speeds and the flow capacity for each road segment of the network, we convert the speed data to flow data and estimate the origin-destination flow demand matrices for the network. Assuming that the observed traffic data correspond to user (Wardrop) equilibria for different times-of-the-day...
A Hopfield-type neural networks (HNN) algorithm associated with histogram navigation method is proposed in this paper for real-time map building and path planning for multiple goals applications. In real world applications such as rescue robots, service robots, mining mobile robots, and mine searching robots, etc., an autonomous vehicle needs to reach multiple goals with a shortest path that, in this...
This paper discusses the scheme and design method for UCAV autonomous/semi-autonomous control system. According to the investigation of the traditional tactical flight maneuvers and the existing air combat simulators, a mission-oriented control scheme is proposed to fulfill the autonomous/semi-autonomous requirements. A library including 9 maneuvers is designed by which complex tasks could be formed...
In recent research, classification involving imbalanced datasets has received considerable attention. Most classification algorithms tend to predict that most of the incoming data belongs to the majority class, resulting in the poor classification performance in minority class instances, which are usually of much more interest. In this paper we propose a clustering-based subset ensemble learning method...
Extended-Range Electric Vehicles (E-REV) are principally battery electric vehicles with a relatively small auxiliary power unit (APU) to recharge the battery pack or directly to propel the vehicle during driving, which is seen as one of the most promising technological bridges between the vehicles of today and the sustainable concepts of tomorrow. Different powertrain system topologies of E-REVs are...
With the increasement of the city vehicles, the problems of traffic accidents, traffic offense and congestion in city become more and more serious. However, the number of the traffic police is limited, so the former ways of working, such as traffic patrol and working at regular places, cannot effectively solve the problems above any more. Through the analysis of the large working scale and mobility...
Mosaic-type combinable flatbed vehicle has multiple axles and all wheels are involved when the vehicle is turning. Through the analysis to certain mosaic-type combinable flatbed vehicle's four-axle steering mechanism, the simulation model of steering mechanism was built. After this, the simulation optimization and analysis to model was done with ADAMS software. The results of the analysis show that...
According to the present development of new energy vehicles, the risk of the new energy vehicles project is analyzed, the risk evaluation index system is established and the rough sets theory is used to reduce the index system in this paper; and exponential whitenization weight function under grey uncertain character of the assessment information is constructed; then the improved grey hierarchy evaluation...
The Urban Public Transportation Information Service System, for the bus arrival time showed on the intelligent electronic station board, is designed to provide accurate and timely information which can help travelers choose transit lines and the shortest paths, can improve the travel efficiency and attract more potential travelers. However, the current bus arrival time prediction model under application...
Common benchmark data sets, standardized performance metrics, and baseline algorithms have demonstrated considerable impact on research and development in a variety of application domains. These resources provide both consumers and developers of technology with a common framework to objectively compare the performance of different algorithms and algorithmic improvements. In this paper, we present...
