Project overview

Jilin 80 kilometers Jingha highway expansion project ：

Collection site photos

Preparation

Field reconnaissance：

Understanding of the

survey area, including the

ramp, service area,

traffic flow, road

conditions, etc. Base station location

planning ： Coverage of the

base station can not be

more than 20 km radius,

and ensure good signal

reception Acquisition route

planning ：Develop a

reasonable collection plan

Data collection –High accurate MMS
