Traffic systems are undergoing enormous change with the advent of Intelligent Transport Systems (ITS). Although productivity and quality of mobility are emerging interests, safety remains the predominant preoccupation of ITS human factors. It should be evident that while intelligent technologies may have the potential to improve traffic safety, they also have the potential to adversely affect it. Ultimately, the effect on safety depends on the specific technologies that are invoked and the manner in which they are incorporated within the vehicle as well as within the larger road transportation system. Current automotive developments can be characterized as technology-centred solutions rather than usercentred solutions. Greater effort must be directed at understanding and accommodating the human element in the road transportation system in order that future transportation objectives can be achieved. There is a need to expand the scope of traditional human factors to include macro-level effects as well as to place greater emphasis on understanding human interactions with other elements of the system. There is also increasing recognition of the urgent need for systematic procedures and criteria for testing the safety of ITS prior to large-scale market penetration. 相似文献

Evaluation of Intelligent Transportation Systems (ITS) at the planning level requires the use of appropriate tools that can capture the dynamic and stochastic interactions between demand and supply. The objective of this paper is to present a methodological simulation-based framework for such applications and implement it in the context of dynamic traffic assignment. The framework consists of a mesoscopic supply simulator and a demand simulator that combines OD estimation capabilities with discrete travel behavior models. Simulation-based DTA systems are particularly suited to evaluate a wide range of Advanced Traffic Management Systems (ATMS) and Advanced Traveler Information Systems (ATIS). The simulation model performance is illustrated through two large-scale case studies in Irvine, California, and Lower Westchester County, NY. 相似文献

微型的感应线圈车辆传感器 总被引:10,自引:0,他引:10
智能交通系统(ITS)是解决日益严重的高速公路和城市交通问题的有效途径.车辆检测传感器是ITS中最重要的交通数据采集设备之一.通过埋在地下或者安装于道路两旁的车辆检测器,可以准确实时地获得各种交通数据(包括车流量、车速度、车辆密度、占有率等).在众多车辆检测器中,感应线圈式车辆检测器具有性能稳定、性价比高、应用方便等优点,因而目前在工程上应用最广.但其探测线圈体积庞大,安装时需要阻断交通,工程量大;线圈容易损坏.本文将采用微型线圈,并将单片机控制技术引入传统的车辆传感器中,从而有效地降低了安装的工程量,开发出适用性更强的车辆传感器.经实验证明,该传感器可有效地检测出车辆信号. 相似文献

Evidently, Intelligent Transport System (ITS) has progressed tremendously all its way. The core of ITS are detection and recognition of traffic sign, which are designated to fulfill safety and comfort needs of driver. This paper provides a critical review on three major steps in Automatic Traffic Sign Detection and Recognition(ATSDR) system i.e., segmentation, detection and recognition in the context of vision based driver assistance system. In addition, it focuses on different experimental setups of image acquisition system. Further, discussion on possible future research challenges is made to make ATSDR more efficient, which inturn produce a wide range of opportunities for the researchers to carry out the detailed analysis of ATSDR and to incorporate the future aspects in their research. 相似文献

In the techno world, the Internet of Things (IoT) is a growing and advanced technology that has become an enormous base for employing in various applications of different genres, including smart vehicle infrastructure, by facilitating Internet connections. Because of the developing nature and the salient features of ensuring high-level road safety and security to optimize traffic management, vehicle networks have become a significant research field in the Intelligent Transportation System (ITS). With various benefits of ITS and IoT, the wireless device transfer connectivity raises the possibility of privacy violations, which may result in surveillance, deflection of identification, and the hijacking of virtual vehicles. Therefore, avoiding data security disputes for computing in the IoT-ITS remains a significant challenge. The IoT supported with Multiple-Objective Genetic Assessment (IoT-MOGA) helps to tackle this problem. The security of knowledge transparency for ITS is suggested in this article. The communication-based vehicle routing method is then configured to retrieve the vehicles from the initial automobile, where the device assignment is placed at the vehicle location. The goal is to improve the consumption of time and energy MOGA to decrease the accomplishing time and avoid conflicts in computer tasks’ privacy. Eventually, investigational assessments are required to demonstrate IoT-MOGA's performance and competitiveness. 相似文献

In Arizona, a window of opportunity exists for using planned infrastructure expenditures to construct intelligent lanes on Interstate Highway 10 between Phoenix and Tucson for deploying intelligent vehicles (IVs). In 1998, the University of Arizona formed the Vehicles with Intelligent Systems for Transport Automation research team, which the ADOT charged with the mission of investigating new and existing technologies and concepts that address those issues. The Arizona state legislature and ADOT funded the VISTA project initially. The paper discusses the vehicle and control system. 相似文献

Design and implementation of a vehicle interface protocol using an IEEE 1394 network 总被引:1,自引:0,他引:1
A wide variety of in-vehicle devices such as camera sensors, navigation systems, telematics and communication equipments have been incorporated into a vehicle to realize Intelligent Transport Systems (ITS) applications. Because an efficient standardized network is required, ITS Data Bus (IDB) has been discussed to carry high-speed multimedia data for audio, video and other real-time ITS applications. For connecting devices in a standardized manner, the IDB network has architecture with a gateway called vehicle interface which is located between automaker’s proprietary network and the standardized IDB network. IEEE 1394 (also known as iLink or FireWire), which can transport multimedia data for consumer electronics, is a good candidate for IDB network. In this paper, we analyze the issues for existing AV/C protocol (application layer protocol over IEEE 1394) to comprise the IDB network. In addition, we designed and implemented the vehicle interface protocol as a higher layer of IEEE 1394 to address the AV/C protocol issues for realizing the whole IDB network architecture. 相似文献

Vehicular Networks is considered a major step in the field of Intelligent Transportation System (ITS). In this technology, some equipment will be installed on vehicles and special places at roadsides which will enable the wireless communication between vehicles with each other and will provide the communication between the vehicles and roadside equipment. One of the ITS application is Traffic monitoring system. Such system enables accessing traffic videos by traffic monitoring centers to make traffic decision. However, providing traffic video for the vehicles can be appealing. This paper addresses a new application in vehicular networks and ITS which can provide this videos for drivers in a city. Each driver request timely traffic video of a location from a web server and the web server forward this request to a stream management server. This server based on current location of the requester vehicle, its speed and its direction calculates appropriate video chunks for each RSU along vehicle destination. This study aims to present a system which can bring a high accessibility for content and can provide it with an appropriate bandwidth and quality for vehicles. Due to the scalability and bandwidth limitations for its content and streaming, vehicular networks are used in this system. 相似文献

Even with a variety of aggressive energy efficiency measures, the ICT sector's carbon emissions will nearly triple from 2002 to 2020. We must accelerate ICT energy efficiency so that we can increase the use of ICT in smart infrastructure capable of reducing global greenhouse gas emissions. 相似文献
