Abstract

The invention discloses a regional multi-direction green wave design and driving speed guiding method based on the Internet of Vehicles. The method comprises the following steps: acquiring geometric parameters and traffic parameters of a road section with a multi-direction green wave design requirement; constructing an optimization model with a multi-direction green wave bandwidth weighted sum as a target, adjusting a signal phase structure, determining a green wave weight, solving the optimization model, and optimizing a period and a phase difference to form green waves for a multi-direction traffic flow; and according to an optimization result of the optimization model, adjusting signal control parameters of a real road network, calculating a driving speed according to optimized travel time, and issuing corresponding speed induction information to traffic flows with different driving directions of a certain road section through roadside equipment. According to the method, the intersection pairs with green wave requirements are taken as basic modeling objects, green wave optimization design can be carried out on any intersection pair in a road network in any shape, and green waves created by the optimization model can provide green waves for traffic flow in any direction in the intersection pair.

Description

technical field [0001] The invention relates to the field of intelligent traffic safety control, in particular to a regional multi-directional green wave design and driving speed guidance method based on the Internet of Vehicles. Background technique [0002] With the rapid development of social economy, people's demand for transportation has been significantly improved. The operational efficiency and carrying capacity of the urban transportation system pose a huge challenge. The Internet of Vehicles technology based on wireless communication technology provides strong technical support for the development of urban intelligent transportation systems, and plays an important role in the daily operation of the transportation system. Utilizing vehicle-to-vehicle (V2I) technology based on on-board equipment and roadside equipment (V2I), efficient and reliable data exchange between vehicles and infrastructure can be achieved, thereby achieving more accurate and detailed traffic g...
