摘　　要：目前高速公路隧道群信息发布亟待解决的问题是:(1)哪些是道路使用者真正需要的信息;(2)如何采用适当的手段发布这些信息。经研究认为,道路使用者最迫切需求的是有关道路畅通和服务水平的信息,其应具备准确、及时、实用和规范的特点。高速公路隧道群交通信息采集设施包括道路信息采集设施、气象信息采集设施、环境信息采集设施、事件信息采集设施等。高速公路隧道群交通信息发布设施主要包括可变情报板、可变限速标志、无线电广播和有线广播等,不同描述对象的交通信息应以最适宜的方式(文字、图形、音频)发布以取得最佳表达效果。在高速公路隧道群路段发生突发事件时,根据距离事件发生点的位置,由远及近依次发布提示信息、建议信息、强制信息和紧急信息,以确保驾驶者行车安全。At present, the pending issues about classification and release of traffic information on an expressway tunnel group are： （1） what kind of information is really needed for highway users？ （2） How to release this information by an appropriate way？ The study shows that the urgently needed information for highway users are those concerning smooth traffic condition and service level with characteristics of accuracy, timeliness, practicability and normaliza- tion. The facilities for collecting of traffic information comprise those involved in road information collection, mete- orological information collection, and environmental information collection and event information collection, while the facilities for releasing the traffic information on an expressway tunnel group consist of variable information bul- letin, variable speed limit sign, wireless and cable broadcasts, etc. The information on different objects shall be re- leased by an appropriate way （word, graph or audio） in order to achieve optimum effects. In case of an incident, such information as attention message, suggestion message, mandatory message and emergency response message should be released in turns from far to near according to the distance to the incident position, ensuring the driving safety.
