Traffic sign design for the integration of expressway interchange and service area
Due to the restrictions of topography,geology,ecological environment and land use in expressways in mountainous areas.,the integration of interchanges and service areas gradually increases.The interchange and service area are the same main exits of expressway,when drivers are unfamiliar to the traffic sign may cause drivers misjudgment,which will inevitably bring safety hazards.Based on the first integrated construction project of expressway interchange and service area in Shandong province,this paper proposed an example of traffic sign design for the integration of expressway interchange and service area.
