With China's rapid economic growth in the implementation of western development, the province's highway construction ushered in before the end of some development opportunities, which the survey and design put forward higher requirements, as the roaddesign industry software technology and hardware equipment development, highway design CAD ​​technology has been achieved, some of the software itself is also required to provide ground support for digital mapping products; establishment survey, design, construction, post-management integrated data link, reducing the data copied,intermediate input link road survey and design is "the integration inside and outside theindustry" requirement, but also affect the development of highway design "bottleneck".Although the current Highway Survey Total Station and other advanced electronicequipment, but through conventional measurement methods, as by the lateral limits and operating conditions, operating strength, and low efficiency, greatly extending the design cycle. Investigation and technological progress is the acquisition of equipment andtechnological innovation, in the current technical conditions, the introduction of GPS technology should be preferred.
