description The invention discloses a green wave coordination control evaluation method and system based on trajectory data. The method comprises the following steps: acquiring basic data of a road, including green wave road data, green wave coordination data, intersection signal control scheme data and vehicle trajectory data; according to the basic data, performing space-time matching on the green wave road data and the vehicle trajectory data, correcting and simplifying the vehicle trajectory data, and generating a new vehicle trajectory data set; generating a coordinated flow network diagram and a travel time network diagram according to the new vehicle trajectory data set; on the basis of a result of the second step, green wave coordination data is combined to generate a coordination bandwidth network diagram; constructing and calculating a green wave coordination index, preferably selecting a green wave coordination scheme based on the three network diagram data, and issuing the green wave coordination scheme to th
