Abstract

The invention discloses a tramcar steering control method and device based on path control. The tramcar steering control method comprises the following steps: acquiring geometrical parameters and traffic parameters of a road section with tramcar green wave design requirements and a target path needing to be optimized; constructing and solving an optimization model aiming at maximizing the weightedsum of the green wave bandwidth of social vehicles, and respectively forming independent green wave bands for a tramcar and the social vehicles by adjusting the signal period, the phase sequence andthe phase difference; and adjusting the signal control parameters of an actual road section according to model optimization results. Based on the traffic flow, the geometric dimension, the vehicle travel time and the phase duration and composition of the actual road section, the periods of all intersections are unified, the phase difference is optimized, and therefore mutually independent green waves are provided for the social vehicles and the tramcar. And the method can be used for modeling a traffic system comprising a single-line tramcar and optimizing a trunk line signal system of a multi-line tramcar.

Description

Technical field [0001] The invention belongs to the field of traffic safety control, and in particular relates to a tram steering control method and device based on path control considering green wave design of steering trams. Background technique [0002] With the rapid economic development, people's demand for transportation has increased significantly, which poses a huge challenge to the carrying capacity and operating efficiency of the urban transportation system. As an efficient and environmentally-friendly public travel mode, trams can effectively carry traffic and reduce the operating pressure of the transportation system. However, due to the imperfection of the green wave signal design method including trams, trams have not yet been widely used. In the applied scenarios, in order to ensure that the trams pass the intersection smoothly, it is often necessary to encroach on the right of way of social vehicles, thereby reducing the operating efficiency of social vehicles. ...
