Embodiment

[0079] The data in this embodiment comes from the SCATS system. The SCATS system has been implemented and applied in many cities such as Shanghai and Shenyang, and has also achieved effective control effects. According to the measured saturation value, the SCATS system predetermines the parameters of period, green signal ratio and phase difference in multiple schemes, and these parameters will not change within a certain period of time.

[0080] A data-driven distributed area control method for traffic road network, including three parts: traffic data filtering, traffic network lane saturation modeling and signal light timing distributed area control. attached figure 1 The urban traffic road network multi-intersection model designed for this embodiment involves multiple intersections. By acquiring intersection data, data processing, road network modeling and distributed area optimization, data-driven traffic road network modeling and distribution are completed. Type area cont...

Abstract

The invention discloses a data-driven traffic network distributed region control method, which comprises steps of traffic data filtering, traffic network lane saturation modeling and signal light timing distributed region control. Rolling optimization is carried out based on a prediction model, a series of future control signals U(k) is set, under given constraints, the best solution U*(k) is solved and is used as input of a control object. A Nash optimization method is further used to solve the correlation problem among multiple subsystems, and the optimal signal period length U<n><*>(k) is acquired. The data driven method is used to do research on a lane saturation prediction model, the signal light region timing optimization based on distributed prediction control is put forward, and aset of high-efficiency control method is provided for avoiding or alleviating traffic congestion.

Description

technical field [0001] The technical field of complex system control of the present invention, in particular, relates to a data-driven distributed area control method of traffic road network. Background technique [0002] With the rapid development of my country's economy and the steady increase of residents' income level, the demand for urban transportation in my country has surged. How to deal with traffic congestion has become one of the urgent problems to be solved in the process of urbanization. Traffic signal timing optimization is one of the effective means to solve urban traffic problems, and its main task is to guide the traffic flow on the road reasonably. The use of intelligent transportation systems to scientifically and effectively manage the existing road network can improve the vehicle traffic rate. While supporting transportation management, intelligent transportation pays more attention to meeting the needs of public travel and public transportation travel...
