Description

Technical Field

[0001] The utility model belongs to the technical field of information volume research of road signs, and in particular relates to an experimental test road sign device capable of switching formats and information. Background Art

[0002] Road signs provide information for drivers to find their way in a dynamic driving state. Too little or too much information is not conducive to the driver's way finding. The survey found that the number of road signs set in most cities is between 4 and 10. The number of cities with road signs with 7 information is the largest, followed by cities with road signs with 4 information. There are many relevant literatures on the reasonable amount of information in road signs. Some scholars have found that the number of Chinese characters should be less than 17 and the number of road names should be less than 6. Other scholars have concluded that "the information limit at 40km / h and 60km / h is 6 and 5 respectively."

[0003] Road signs are part of the road guidance system. The recognition of road signs should be in a guiding environment, and the target road name to be searched should be a road name that plays a role in road finding. Based on the path finding theory, analyzing the road sign information required by drivers in the path finding process and studying the information demand that affects the driver's cognitive time are another new direction for the reasonable information volume of current road signs. Studies have found that there are many reasons for the different information volume of road signs between different cities, and the layout of road signs is one of the important reasons. In order to further explore the impact of different layouts and information road signs on the search time of target road names, it is necessary to conduct road experimental tests. The existing technology is to make multiple road signs with different layouts and information. However, in actual testing, after the test of a certain layout of road signs is completed, it is necessary to disassemble and replace the layout to be tested. However, the sign bracket is relatively high, and disassembly and replacement are time-consuming and laborious, which affects the test progress, especially in different locations and different road conditions. The test scenario has a large test volume. For this reason, it is very necessary to develop an experimental test road sign device that is easy to operate and does not require frequent disassembly and can switch the layout and information.
