公路隧道交通工程设计

公路隧道交通工程的设计,主要从隧道交通安全、功能服务、防灾救灾和交通管理四个方面考虑，具体由标志和标线、交通监控设施、通风与照明控制设施、紧急呼叫设施、火灾报警、消防与避难设施、供配电设施和中央控制管理系统与设施等组成,介绍了设计的指导思想,解释了各内容的功能和作用，同时指出了设计中存在的问题。

Design of Traffic Engineering Facilities of Highway Tunnels

Four major aspects, i. e. , traffic safety, function and service, disaster prevention and control and traffic control should be considered in the design of the traffic engineering facilities of highway tunnels, which consist of traffic signs and traffic mark lines, traffic monitoring facilities, ventilation and lighting facilities, trumpet call system, fire alarming system, fire fighting and escaping facilities, power supply and distribution facilities, central control and management system. In the paper, the guiding principles for the design of the traffic engineering facilities of highway tunnels are presented, the functions of each kind of traffic engineering facilities are interpreted and the problems in the design of the traffic engineering facilities of highway tunnels are pointed out.
