A dynamic guidance method for construction area based on bionic traffic man robot

Abstract

The invention proposes a dynamic guidance method for a construction area based on a bionic traffic man robot. According to the principle of electromagnetic induction, portable geomagnetic sensors are deployed on the merging road surface of the expressway construction area to obtain real-time traffic flow data; according to the dependence effect, the urban traffic police's traffic gestures are linked with the actions of bionic traffic officers; according to the real-time traffic flow state, the typical construction merging area Traffic flow status, and then trigger different guidance actions of bionic traffic guides; and make specific suggestions for bionic traffic guides according to the existing technology. The invention uses a portable geomagnetic sensor to monitor the traffic flow in the confluence area of ​​the construction section in real time, triggering bionic traffic personnel to perform different actions, so as to realize dynamic and standardized guidance and reduce the probability of rear-end collision accidents; the invention can effectively perform dynamic guidance and reduce In the event of an accident, assist the safe and efficient operation of the expressway construction area.

Description

technical field [0001] The utility model relates to traffic safety technology, in particular to a dynamic guidance method for a construction area based on a bionic traffic man robot. Background technique [0002] In recent years, the number of motor vehicles in my country has continued to increase, and expressways, as an important part of the national road network, have successively carried out reconstruction and expansion projects. Reconstruction and expansion operations often require flag bearers to swing flags back and forth in the upstream transition area to warn and guide passing vehicles to pay attention to road construction ahead. However, the situation in the reconstruction and expansion construction area is complicated and the existing facilities are uneven, resulting in frequent accidents and serious losses. The "Strategy of Building a Powerful Transportation Country" promulgated by the state requires improving the level of intrinsic safety, improving the professio...

AI Technical Summary

Problems solved by technology

The artificial flag bearer has the following disadvantages: the flag bearer is in an extremely unsafe state, and cannot work continuously, which affects the construction safety; the labor cost is high

[0004] After field research and data analysis, it was found that the traffic flow status in the merge area of ​​the expressway construction section showed the following two characteristics. ① When the inner or outer lanes were closed, the inner and outer lanes showed a large speed difference, and related research showed that the vehicle speed difference If it is greater than or equal to 20km / h, it will bring huge potential accidents; ②There is a risk of conflict between vehicles at the merging point
