The launch event of the National Key R&D Plan Autonomous Road Traffic Control and Safety Project was held on December 28 in Wuzhong District, Suzhou City.
The "Device-Network-Cloud Integrated Road Traffic All-Element Intelligent Control Technology" and "Autonomous Road Traffic System Safety Assurance Technology" projects under the national key research and development plan have been officially signed and launched. This project is led by the Road Traffic Safety Research Center of the Ministry of Public Security and the Traffic Management Science Institute of the Ministry of Public Security. At the same time, the autonomous driving traffic regulations compliance training (Suzhou) base project was also unveiled today.
Inquiries on this site found that China’s first holographic perception smart highway project that meets the vehicle-road collaborative autonomous driving level has been put into use in Suzhou. The project covers the Su-Taiwan Expressway S17 (Huangdai Interchange-Xiangcheng Hub) and the Shanghai-Yiyi Expressway S48 (Xiangcheng Hub-Yangcheng Hubei Interchange), with a total length of 56 kilometers. Among them, the road section capable of L4 level autonomous driving testing is 6.5 kilometers, which is located on the one-way section from Weitang Interchange to Xiangcheng Hub.

sensing equipment such as lidar, millimeter wave radar, camera, roadside antenna RSU, etc. have been deployed at 55 points to create Holographic sensing road sections and ramp (interchange) sensing road sections. The project passes through Beiqiao Interchange, Weitang Interchange, Xiangcheng Hub, and Yangcheng Beihu Service Area. The subdivided scenes along the line include toll stations, ramps, service areas, etc.
The holographic sensing road section is located on a 6.5-kilometer one-way section from Weitang Interchange to Xiangcheng Hub, with the direction from west to east. In this section of the road, two information prompt screens are set up, located at the entrance and middle of the holographic main road. In addition, laser radar, cameras and other equipment are deployed at an average of every 230 meters at each point. At the same time, a series of antenna RSUs are also set up on the roadside, with a distance of approximately 460 meters between each other. The sensing road section refers to a ramp (interchange) equipped with a series of devices that can sense vehicles entering and exiting the test road section. The main equipment of each sensing road section includes cameras, roadside antenna RSU, and millimeter wave radar. The function of these devices is to monitor and identify vehicles through different technical means, thereby achieving real-time perception and monitoring of the vehicle's driving status. Cameras can capture images and videos of vehicles, roadside antennas (RSUs) can receive and send vehicle communication data, and millimeter-wave radar can be used to measure information such as distance and speed of vehicles. Through the collaborative work of these devices, the sensing road section can accurately monitor and identify vehicles entering and exiting the test road section, providing important data support for traffic management and safety.

9月26日消息,中国高铁网络迎来了新的成员。今天上午,广东省正式启用了一项重要的交通基础设施,广汕高铁开始运营。首次G9726次高铁列车于上午8时30分从广州东站缓缓启动,开始了漫长的旅程,经过新建的广汕高铁,约73分钟后成功抵达汕尾站广汕高铁全长200公里,设计时速高达350公里/小时,线路上共设有8座车站。其中,新塘站与广深三四线相连,是广深城际铁路的要道。博罗至惠州北、惠州南至仲恺的联络线增强了与周边地区的联系。据了解,这项工程不仅是广东省内的一大交通亮点,也是中国东南沿海高铁通道的重要组

上海久事集团旗下交通卡公司与AlipayHK合作推出了全新的“上海公共交通乘车码”服务。这一服务为非中国内地用户提供了一种便捷的直接扫码乘车方式。从2月6日起,所有使用AlipayHK的用户都可以通过此服务,在上海公交车、地铁等交通工具上直接扫码支付车费,无需再购买实体交通卡。这是上海公共交通领域首次对外国游客提供的便利服务,为他们提供了更加便捷、快速的出行体验。香港朋友在上海可以像内地用户一样享受同等换乘优惠,使用AlipayHKApp刷码消费,乘坐公交车、轮渡、松江有轨和金山铁路,方便快捷。

自动驾驶汽车能够准确绘制周围环境的地图,并监测附近车辆、交通灯、行人和车道标记等的位置以及实时情况。目前的研究表明,尽管仍需对其中每个子系统进行重大改进,才能实现功能全面、安全的自动驾驶汽车,但一旦实现了这些里程碑式的改进,人们不仅会改变汽车的操作方式,还会发现其所带来的影响远远超出自动驾驶汽车领域。美国《福布斯》双周刊网站在近日的报道中,展望了自动驾驶汽车有望改变未来世界的4种方式。减少交通事故世界卫生组织提供的数据显示,全球每年约有130万人死于交通事故,这一数字在2030年有可能达到220

随着城市化的快速发展和交通需求的日益增加,交通无人机作为一项创新技术,正逐渐在城市交通管理中展现出其独特的应用价值。本文将详细探讨无人机在交通领域的应用现状,并重点关注其在交通监控、事故现场勘察和交通管制与引导方面所取得的成果。交通监控与管理是一项重要的任务。它涉及到监控和管理道路上的交通情况,以确保交通的安全和顺畅。通过安装摄像头和其他监测设备,可以实时监控交通状况,包括交通流量、车辆速度和违规行为。监控中心可以通过收集和分析这些数据来制定有效的交通管理策略。此外,还可以使用交通信号灯和路标来

在知乎上看到这么一个问题,十年后可以实现无人驾驶普遍化吗?并提出现在是否还有必要学习驾照。这是一个非常有趣的问题,因为这个问题涉及到了自动驾驶商用化的时间可能以及自动驾驶落地后我们的生活会发生哪些改变。在这个问题中,还涉及到了一个概念,即普遍化,这也是非常值得讨论的问题。智驾最前沿将从这一个问题着手,与大家进行讨论。自动驾驶关乎智能出行、智能交通、智能城市,是未来发展的一大趋势,也将会是改变社会生活方式的一项技术转变。自动驾驶,简而言之就是汽车控制角色的转变,现在我们的出行过程中,完全离不开人的

要判断能否安全地穿过宽阔的道路,需要行人和驾驶员之间的社交提示和配合交流。那么,如果是自动驾驶车辆会怎样?自动驾驶汽车公司Motional认为,让车辆更善于表达可能是维持这些重要信号的关键。在人行横道上等候时,Motional的首席工程师保罗•施密特(Paul Schmitt)体验到了他称之为“一瞥共舞”的感觉。这是一种快速且几乎是潜意识的评估:迎面而来的汽车驾驶员看向哪里?他们是否注意到他?“而对于自动驾驶车辆,这种交互有一半都不存在了。”施密特说,“因此,有哪些提示可供行人了解车辆的意图?

国家重点研发计划自主式道路交通控制与安全项目的启动活动于12月28日在苏州市吴中区举行。国家重点研发计划的“端网云一体化道路交通全要素智能控制技术”和“自主式道路交通系统安全保障技术”项目已经正式签约启动。这个项目是由公安部道路交通安全研究中心和公安部交通管理科学研究所牵头进行的。同时,自动驾驶交通法规符合性训练(苏州)基地项目也在今天揭牌。本站查询发现,国内首条满足车路协同式自动驾驶等级的全息感知智慧高速公路项目已经在苏州投用。该项目涵盖了苏台高速S17(黄埭互通-湘城枢纽)和沪宜高速S48(
