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 the intersection for execution; and constructing and calculating a green wave coordinated operation index, and monitoring the green wave operation state of the road in real time. According to the method, fine evaluation of the green wave scheme is realized in the scheme design and implementation operation stages to a certain extent.
