Especially, for the convenience and safety of residents' life, they acquire necessary information through various methods from urban planning to various aspects . One of the representative collection information for smart city design is traffic information. Accurate new city development area and surrounding traffic information are essential elements for efficient urban and transportation network and Intelligent Transport System (ITS) design. .

Conventional traffic information collection system for intelligent traffic system design has embedded an image detector or loop detector on the roadside, and collects and uses vehicle speed and traffic volume through it. However, there are no detectors installed in a number of national roads or new cities, and in this situation, a method of estimating using the data of surrounding roads installed with sensors for collecting traffic information is used. And it is difficult to collect and analyze accurate traffic data.

Further, in order to use the traffic information collection system using the conventional image detector or loop detector, a lot of manpower and high cost are required for installation and maintenance. In the case of local governments, public institutions, and transportation engineering companies that need to conduct business feasibility studies and traffic impact assessments for traffic investigation and analysis, investment and evaluation of transportation projects, There are many.

On the other hand, it has been pointed out that such conventional traffic information collection methods can not obtain information related to the types of vehicles. In the conventional system, a researcher who manages an interval of 60 km per person on average according to the distance of the collection section is used to observe the amount of traffic (irradiation amount) passing through the branch office. However, because of lack of transportation experts, efficient collection and continuous analysis and management of information is difficult.

One end of the leg supports 122 is folded inward of the legs 121 And the other ends are hingedly connected to each other via a support member connecting member 122a so as to be foldable. The supporting member connecting member 122a connecting the leg connecting member 121a to the leg supporting member 122 is formed in an inner ring shape so that the pole 110 can be vertically inserted and retracted . The pole piece 110 which can be lifted up and down by the leg connecting member 121a and the supporting member connecting member 122a is fixed to the foldable pedestal 120 by the fixing member 123. In the embodiment of the present invention, 123 are realized through a fixing nut formed on the connecting members 121a, 122a and a fixing bolt fastened to the fixing nut.
