目前,我国高速公路网络发展迅速,给人们带来交通便利的同时,也产生了许多问题。如何提高对高速公路各路段的综合管理水平,充分发挥路网中各高速公路之间快捷、畅通的通行优势,最大限度地降低人为干扰因素,已成为摆在高速公路管理者面前的一项新的研究课题。为此,尽快实现联网收费成为交通管理部门的重要工作目标之一。文章从工程应用的角度,对当前高速公路收费站应用无人值守自动发卡机工作流程的特点和通信过程中可能遇到的问题进行详细分析。 At present, the expressway network in our country is developing rapidly, which brings convenience to people as well as many problems. How to improve the comprehensive management level of every section of freeway, give full play to the advantage of quick and smooth passage among expressways in the road network, and minimize the factors of human disturbance has become a new issue for highway managers Research topic. To this end, as soon as possible to achieve Internet access fees become the traffic management department one of the important objectives. From the perspective of engineering application, the article analyzes the characteristics of the current unmanned automatic card issuing machine workflow in highway toll stations and the problems that may be encountered in the process of communication.
