Embodiment Construction
[0050] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0051] The purpose of the present invention is to propose a method for estimating the queue length of each flow direction and each period of the intersection by using the low-permeability vehicle trajectory data within the intersection range. For vehicles equipped with mobile phone positioning APP, its positioning information includes: user ID, longitude, latitude, recording time and instantaneous speed and other information are recorded at a relatively high frequency to form vehicle trajectory data. The method of the invention utilizes these data as a single input, combines the traff...
