Dynamic routing optimization system and method based on real-time traffic information

Abstract

The invention provides a dynamic routing optimization system and method based on real-time traffic information. The dynamic routing optimization system based on the real-time traffic information comprises an information acquisition unit, and the information acquisition unit is communicated with the information publishing center of a traffic management department and can acquire closed road information timely. When a road is closed and impassable due to emergencies such as traffic control, traffic accidents and road construction, even though road information acquired by the information acquisition unit shows that the road is clear and congestion-free, the corresponding road on an information display unit can still be marked as impassibility, so that the road can avoid being chosen an optimized road to misguide people in traffic. According to the dynamic routing optimization system and method based on the real-time traffic information, the routing optimization is based on a dynamic traffic network data set, and influences of dynamic information such as traffic accidents and traffic incidents of the road network on the road traffic are taken into consideration.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation applications, in particular to a dynamic route optimization system and method based on real-time traffic information. Background technique [0002] With the development of economy and society, the number of cars is increasing at an alarming rate, and the construction of roads lags far behind the increase in the number of vehicles. Traffic congestion has also become a factor hindering economic development, and the best way to solve traffic congestion is to carry out Path guidance, reducing the running time of vehicles on the road. This technical field has also become a hot field of international research. Path selection is the core technology in this technical field. Therefore, the route optimization method is also the most concerned by technical personnel. The so-called route optimization refers to providing the optimal route for vehicles under certain optimization objectives...

AI Technical Summary

Problems solved by technology

[0006] What the present invention aims to solve is that in the prior art, when selecting the optimal route based on dynamic traffic information, the technical problem of easily selecting the closed road segment as the optimal route without considering the situation that the road section is closed and unable to pass through is not taken into account. A dynamic route optimization system and method based on real-time traffic information to obtain the optimal route suitable for vehicle traffic after the sudden event on the road network excludes the closed road section
