【摘要】：我国高速公路作业区有着交通秩序混乱、管理僵硬、区段功能不清楚的特点，再加上现在高速公路交通量过多的问题，使得作业区成为交通事故的常发点，但在国内大规模高速公路建设已完成的阶段，养护作业的现象只会愈来愈多，因此，采用合理、动态的管理手段有助于提高作业区的通行能力，也对作业区安全保障有着重要的意义。专用短程通信技术（Dedicated Short Range Communications）缩写为DSRC。本文从DSRC技术在作业区的实际应用出发，总结以往的研究成果，对作业区进行区段划分，并探索DSRC技术在作业区中的适应性；对于DSRC下作业区的检测技术，先分析作业区管理中的信息需求，确定需要检测区检测的动态交通信息，以此为依据，在对比现有交通检测技术，和分析其在作业区适应性的基础上，，选用波频车辆检测器进行交通检测，再基于数据传输及检测范围需求布设检测器；分析DSRC数据传输的基础—DSRC协议，为DSRC数据传输设计提供基础，以车辆制动稳定性推算不同附着系数下车辆的制动效率，在保证车速差在15km/h下车辆跟驰安全计算作业区限速值和限距值；对于警告区选用可变信息情报板对车流实现动态管理，并基于驾驶员的视认过程计算可变信息情报板的设置位置。本文的研究结果为作业区的管理控制提供了科学的方法和依据，对提高作业区交通运行的安全与效率具有重要意义，同时也为今后对作业区管理提供了思路。
[Abstract]:The expressway operation area in our country has the characteristics of chaotic traffic order, rigid management, unclear function of the section, and the problem of excessive traffic volume on the highway, which makes the operation area a frequent occurrence point of traffic accidents. However, in the stage of large-scale expressway construction in China, the phenomenon of maintenance operation will only become more and more frequent. Therefore, the use of reasonable and dynamic management means will help to improve the capacity of the operation area. Also has the important significance to the operation area safety safeguard. Dedicated short range Communications is abbreviated to DSRC. Starting from the practical application of DSRC technology in the operation area, this paper summarizes the previous research results, divides the work area into sections, and explores the adaptability of DSRC technology in the operation area. Based on the analysis of the information demand in the operation area management and the determination of the dynamic traffic information to be detected in the operation area, this paper compares the existing traffic detection technology and analyzes its adaptability in the operation area. The vehicle detector with wave frequency is selected for traffic detection, and then the detector is arranged based on the requirement of data transmission and detection range, and the basic DSRC protocol of DSRC data transmission is analyzed, which provides the basis for the design of DSRC data transmission. The braking efficiency of vehicles with different adhesion coefficients is calculated from the braking stability of vehicles, and the speed limit and the limit of the operating area are calculated under 15km/h to ensure the vehicle speed difference. For the warning area, the variable information board is used to realize the dynamic management of the vehicle flow. The location of the variable information board is calculated based on the driver's recognition process. The results of this paper provide a scientific method and basis for the management and control of the operation area. It is of great significance to improve the safety and efficiency of traffic operation in the operation area, and it also provides a way of thinking for the management of the operation area in the future.
