This paper examines American attitudes about the role and structure of government and how those attitudes affect the safety potential of ICT-based road safety technologies. It examines these attitudes in the context of 3 current intelligent transportation systems (ITS) initiatives: IntelliDriveSM, active traffic management (ATM), and automated enforcement. It concludes that cultural attitudes have a strong influence on the acceptance of such systems, and provides suggestions for how such systems might be implemented successfully. 相似文献

基于GPS与IC卡的公交OD量采集方法 总被引:1,自引:0,他引:1
公交OD量是公交调度管理及线网优化的基础。传统的获取公交OD量的方法需要进行大范围的个人出行情况调查,消耗大量人力物力,且数据更新缓慢。随着GPS技术与IC卡在公交系统中的广泛应用,提出了利用公交车GPS定位与乘客IC卡刷卡信息来获取公交OD量的新方法。利用这一方法对广州某段时间的公交车GPS定位和羊城通数据进行了实际分析。试验结果表明这一方法是有效的。 相似文献

Public–private partnerships (PPPs) play an important role in bringing private sector competition to public monopolies in infrastructure development and service provision and in merging the resources of both public and private sectors to better serve the public needs. However, in worldwide practices, there are mixed results, substantial controversy, criticism and conflict over PPPs. This paper proposes a systematic framework for the delivery of public works and services through PPPs in general. Justified by public procurement principles, aimed at a public–private win–win solution, and based on worldwide best industrial practices and lessons from unsuccessful projects, this framework integrates the four broadly divided stages that repeat over time: (1) design of a workable concession, (2) competitive concessionaire selection, (3) financial regulation, and (4) periodic reconcession and rebidding. The four-stage framework takes into account the requirements of public services, realignment of responsibility and reward among multiple participants in PPPs, the monopolistic rights of the concessionaire, and the wide range of risks and uncertainties in the long concession period. Varying competition elements are incorporated in each of the four stages for continuous performance improvement in the delivery of public works and services. The design of the right concession forms the base on which other stages are implemented in addition to planning the project and allocating risks for enhanced efficiency. The financial regulation allows the government to address changing conditions and to regulate the concession for efficient operation with due discretion, whereas the competitive concessionaire selection and periodic reconcession and rebidding play critical roles in achieving innovation, efficiency and cost effectiveness through direct competition rather than government discretionary intervention. 相似文献

运用定性和定量相结合的方法研究智能运输系统(ITS)中综合运输及运输管理关键标准。具体如下:在目前的综合运输及运输管理标准体系表中,对一部分显而易见的标准先用定性的方法分析其是否为关键标准,得出第一部分关键标准。然后对剩下的标准运用层次分析法和聚类分析法相结合的方法,得出第二部分关键标准,即先用层次分析法得出各专家的权重向量表,对所有的权重向量表进行聚类分析,得出综合权重向量,按照综合权重向量确定第二部分关键标准。最后,合并两部分得出综合运输及运输管理关键标准。 相似文献

As growing demand of vehicle safety system, especially regarding intelligent transport systems (ITS), automotive manufacturers are focusing more on driving safety and efficient transportation for vehicle users. Many safety systems have been launched in the market recently so, it is important to evaluate the vehicle safety systems and ITS. The ITS based intelligent vehicle test bed was constructed to meet the growing demand of test and verification for such ADAS and ITS systems. First, this paper describes in detail concept of the test-bed. This test-bed is carefully designed to meet the requirements of ISO/TC204 standards. In order to verify the design of the test-bed, virtual test with driving siulator was processed on a virtual test tracks. This test-bed will be used to conduct testing on various ITS and ADAS technologies, such as adaptive cruise control (ACC), lane departure warning system (LDWS), cooperative intersection warning system as well as rollover stability control (RSC) and electronic stability control (ESC), etc. 相似文献
