Construction area dynamic guiding method based on bionic traffic officer robot

Abstract

The invention provides a construction area dynamic guiding method based on a bionic traffic officer robot. The construction area dynamic guiding method comprises the following steps: according to the electromagnetic induction principle, arranging a portable geomagnetic sensor on the confluence road surface of the expressway construction area to obtain real-time traffic flow data; associating the traffic dispersion gestures of the urban traffic police with the actions of the bionic traffic officers according to the dependency effect; matching the typical traffic flow state of the construction confluence area according to the real-time traffic flow state, and then triggering different guidance actions of the bionic traffic officers; and putting forward specific suggestions for bionic traffic guides according to the prior art. According to the construction area dynamic guiding method, the portable geomagnetic sensor monitors the traffic flow of the confluence area of the construction section in real time, and triggers the bionic traffic officers to execute different actions, so as to realize dynamic and standard guidance and reduce the probability of occurrence of rear-end collision accidents; and dynamic guidance can be effectively carried out, accidents are reduced, and safe and efficient operation of the highway construction area is assisted.

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...

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
