长益及益常整合中益常段高速公路的价值评估 总被引:2,自引:1,他引:2
高速公路未来收费权的价值评估对于湖南省高速公路实施滚动式发展是至关重要的一个环节。在长益及益常高速公路进行整合的过程中,对益常段高速公路未来收费权进行合理的价值评估不仅能保证国有资产的保值增值,而且对交通行业主管部门有效地引进外部资金及合理地选择高速公路运营单位的整合模式尤为关键。 相似文献

随着收费公路在各省区内成网,ETC应运而生。在国家取消高速公路省界收费站的进程中,ETC用户的占比成为此项改革成败的关键指标。文章通过对ETC在我国及内蒙古地区的发展历程分析、解读,旨在明确取消省界站和推广ETC在逻辑上顺承和事实上依存关系,同时,探讨ETC在内蒙古的推广应用,明确指出随着云计算、大数据、边缘计算、AI的迅速普及和高效运用,未来这张网的走向应该是产业互联网。 相似文献

Driving road identification is the key issue of a vehicle navigation system that supports various services of intelligent transportation systems. The method for driving road identification is also known as map matching (MM). In spite of the development of MM algorithms, limitations still exist in obtaining the positioning data and preparing candidate roads (CRs) that may result in mismatches in some special difficult road configurations such as flyovers and parallel roads. To overcome the limitations, an integrated trajectory-based MM (tbMM) system is proposed based on the trajectory similarity evaluation method. The system can fuse the information from global positioning systems (GPS) and inertial sensors to generate the vehicle trajectory that represents the vehicle continuous movement in three dimensions. The elevation data of vehicle and roads are involved to enhance the trajectory-based matching process. Also the method employs an optimized mechanism for generating and maintaining CRs. Using the mechanism, separated road segments in a digital map are reorganized in the form of possible driving roads and the topology among them is guaranteed. Moreover, the CRs are obtained considering all the possibilities in determining the driving road so that the valuable historical information can be effectively reserved to provide more reliable matches in ambiguous situations. The tbMM system was evaluated using a number of real-world vehicle-level test datasets in urban areas in Beijing. Also a comparison test was performed to evaluate the driving road identification accuracy against existing MM algorithms. The results show that the tbMM system can provide reliable matches with about 99% accuracy in all the difficult scenarios and outperforms the existing algorithms. 相似文献

Recently, the demand for car rentals has been increasing at tourist destinations in Japan due to their convenience and the high degree of freedom they offer. On the other hand, there is a problem of a dramatic rise in the number of traffic accidents involving drivers from countries with different traffic customs and cultures from Japan. In order to examine measures to reduce the traffic accident risk of foreign drivers visiting Japan, an animation video to promote safe driving was created and its educational effects were tested in this article. First, through a driving survey of foreigners and a review of preceding studies, we identified information on Priority, Speed, and Comprehension (PSC) that must be learned by foreign visitors to reduce their accident risk. Next, drawing from the technique of branded contents in order to enhance the effects of educational videos, we created a short video that conveys the PSC philosophy that should be understood for safe driving in Japan. We then tested the educational effects of the video by conducting a survey of Taiwanese people. The results show that strengthening the video's appeal leads to improvements in educational effects and therefore safety awareness. We also realized that the effect was particularly significant among young people in their twenties. Lastly, the rent-a-car businesses evaluated the videos and basing on their input, we summarized effective ways for foreign rent-a-car users visiting Japan to use the video. 相似文献

驾驶室型正三轮摩托车中置自然风冷型发动机设计方案还不够成熟,发动机台架试验及车辆道路试验数据均表明该类车型的发动机缸头及机油温度过高,散热困难,导致了发动机输出功率及转矩降低,使用寿命也较短。选择强制风冷发动机来代替自然风冷发动机,由于低速大转矩的特点,会增加车辆的燃油消耗及尾气排放,同时使车辆的加速及超越加速性能大大降低。 相似文献
