The invention discloses an urban trunk road two-way green wave control optimization method based on a road section speed interval. Through historical vehicle driving speed data, a driving speed fluctuation interval is quantized, and phase green time is coordinated and phase difference parameters are optimized in a condition in which the vehicle speed is uneven. On the basis of fully considering road section speed stochastic fluctuation and non-coordinated phase passing requirements, a trunk road two-way coordination control optimization method with maximization of a green wave band width between adjacent two crossings as a target is brought forward, overlapping test is carried out, and thus a phenomenon that the green wave band may be broken can be prevented. Defects that an average vehicle speed assumption is adopted traditionally, and unevenness of the vehicle speed is neglected are overcome, the trunk road traffic flow operation efficiency can be effectively enhanced, operability of actual applications can be ensured due to good practicality features, and positive significance is provided for building an urban road traffic signal control optimization system and enhancing an urban traffic management and control level.
