前 言

        交通是人类行为的重要组成和重要条件。智能交通系统作为未来交通系统的发展方向，其本身就是将先进的信息技术、数据通讯传输技术、电子传感技术、控制技术及计算机技术等有效地集成运用于交通管理之中，从而建立一种在大范围内、全方位发挥作用的，实时、准确、高效的综合交通运输管理系统。
        当前，以“保障安全、提高效率、改善环境、节约能源”为目标的智能交通技术研发已经受到各国的重视，我国的智能交通也实现了快速发展，许多技术手段都达到了国际领先水平。但是，问题和困境也非常突出，城市交通拥堵范围不断扩大、程度日益加深，我国道路交通及人车出行问题仍然是影响人们生活、制约城镇化进程和社会经济发展的瓶颈。
        在美国、日本等发达国家和地区，有关城市交通管理服务模式探索起步早，拥有较为丰富的管理经验。只有管理服务模式呈现大数据下的智能化，才能实现城市交通管理中的以人为本。譬如基于大数据分析的人流和车辆信息等，可以对人们低碳、便捷出行提供依据。此外，面对当前机动车迅猛增长的趋势，智能化交通管理也是当务之急。
        基于这样的背景和环境，我们希望通过召开此次会议搭建一个国际交流平台，吸收和融合国外先进的城市交通管理理念和技术，并在此基础上推动嵌入式与网络计算湖南省重点实验室在智能交通技术方面的创新和可持续发展。
        2017中日智能交通国际研讨会为期一天，将有中日七位专家发表主题演讲，互动交流最新的智能交通相关技术。

Wireless Sensors and Power Transfer Technologies for Mobile Applications

**Minoru Okada , Professor , Graduate School of lnformation Science, Nara lnstitute of Science and Technology, Japan

Automated Guided Vehicle (AGV) is a robot mainly used for carrying materials in a factory. AGV is capable of increasing the productivity, recharging the batteries is required after the operation, and it interrupts the operation. Therefore, the battery charging to the moving AGV is required for further improving the usability. In this presentation, a wireless power transfer (WPT) system based on parallel feeder line. The proposed WPT is capable of sending power to the moving vehicles alongside the feeder line. The experimental results showed that the developed WPT can send the electrical power to the moving vehicle in more than 100 meters of feeding area.
Another requirement in AGV is positioning capability. To navigate AGV,　it estimates its positions accurately. We have developed a novel positioning scheme using leaky coaxial cable (LCX) based positioning scheme. The LCX is a specially designed coaxial cable with many slots on the metallic shield. Unlike the normal coaxial cable, the radio wave is leaked through the slots on LCX. The proposed positioning scheme can estimate the position of AGV by measuring the leaked radio waves. The proposed scheme with super resolution algorithm based on the noise subspace algorithm can further improve the positioning accuracy. The proposed wireless sensor and power transfer technologies are capable of applying the future autonomous vehicles.

Abstract: 目前世界各国对于第五代移动通信系统（5G）都进行大量的投入和研究开发。该报告将首先介绍目前日本在这个领域的研究投入和研究趋势， 然后重点介绍报告人在日本国际电气通信基础技术研究所（ATR International）以及日本奈良先端科学技术大学院大学（NAIST）期间所主持和分担的日本总务省在面向第五代移动通信系统的多天线技术的重点投资研究项目的研究结果。多用户多天线技术(MU-MIMO)的投入和系统开发和测试结果。通过线性MU-MIMO技术与非线性MU-MIMO系统的设计开发和测试的系统结果比较来介绍目前多天线技术的系统实现面临的主要难题。这些研究开发结果同时也为面向5G的Massive MIMO的系统实现给出大量的经验借鉴。同时本报告也将简要介绍采用新型天线设计诸如漏泄同轴电缆(LCX)天线和电控无源阵列天线（ESPAR）所带来了系统增益以及研究进展。

Smart Sensing on the Wheels

**Yanmin Zhu, Professor，Department of Computer Science and Engineering at Shanghai Jiao Tong University, China

Abstract: The rapid advance of embedded sensing and mobile Internet has bring unprecedented opportunities to make our cars smarter. In this talk, we provide several interesting examples that showcase how smart sensing help drivers to access real-time context information about the car and the environment where the car is moving. First, we present a lane-level localization system, which can perform real-time vehicle localization on lane-level only using smartphones when vehicles are driving on highways. The system uses embedded sensors in smartphones to capture the patterns of lane change behaviors, and then tracks vehicles on lane-level with tolerance of false detections. Second, we present a smartphone based system called DEEL for detecting road elevation as the vehicle moves on urban roads. HMM-based models are built to characterize the patterns of vehicle dynamics with respect to the elevation of the road that the vehicle is moving on. The system leverages smartphone sensors to sense the instantaneous vehicle dynamics, including the 3D acceleration, the speed, and the number of perceived GPS satellites. Based on the sensed dynamics, it determines whether the vehicle is running on an elevated road or not in an online fashion.

Big data Analysis on Japanese Express Home Delivery Services

**Takao Terano, Professor ，School of Computing, Tokyo Institute of Technology, Japan

Abstract:Japanese Express Home Delivery Service or TAKKYU-BIN is one of most sophisticated person-to-person home delivery services in the world. However, recently, the ration of person-to-person services has become decreasing, instead e-commerce delivery service has become major parts. Thus, to improve both the performance and the service levels, they must focus upon big data analytics in every task. To deal with the difficulties, we have conducted a research project with Yamato Transport Co. Ltd., one of the major company in TAKKYU-BIN business in Japan. The project covers very wide area of the business systems, which includes 1) Data analysis on truck scheduling; 2) Simulation analysis in delivery deposits; 3) Home delivery route optimization; and 4) Future placement design of large delivery centers. In this talk I would like to give the overview of the project and specific topics on transportation issues of the business.

Achieving High performance Low Power NVMs through Loop Transformations

***Keni Qiu, Research Associate Professor, Capital Normal University, Beijing, China

Architecting emerging NVMs, especially STT-RAM, PCM, ReRAM etc., as cache or main memory for embedded systems is a promising technique to replace conventional SRAM/DRAM deployments. However, these emerging NVMs often suffer from long latency and large energy on write operations. Targeting stencil loops with data dependencies, we present several loop transformation techniques such as loop retiming, loop tiling and loop scheduling to reschedule loop traversals such that the negative impacts from NVM write operations can be efficiently mitigated or avoided. As such, high performance and low dynamic power can be obtained during loop execution.
