问题 What is the appropriate title for the passage?
According to the passage, the smart-highway technology is aimed to ______.
选项 A、deploy sophisticated facilities on the interstate highways
B、provide passenger vehicles with a variety of services
C、optimize the highway capabilities
D、improve communication between driver and the people who monitor traffic
答案C
解析 细节题。由题干smart-highway technology定位到第二段首句“智能公路的目的就是使交通系统的效率最大化”，由此可知选C。根据第二段可知A“在城际高速路之间安装精密仪器”是智能公路“智能化”的具体措施，而不是主要目的；B“给客车提供各种服务”和D“促进司机与交通监控人员之间的信息交流”均是智能公路的具体功能。
