Embodiment Construction

[0052] Attached below figure 1 , attached figure 2 , attached image 3 , attached Figure 4 And attached Figure 5 The present invention is described in detail. 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.

[0053] Such as figure 1 As shown, a path control-based tram steering control method disclosed in an embodiment of the present invention includes the following steps:

[0054] Step 1. Obtain the geometric parameters, traffic parameters and the target route to be optimized of the road section with tram green wave design requirements.

[0055] Under normal circumstances, the road section with tram green wave design requirements should be a road section where the flow of the main road is much larger than that of the secondary road. The target path includes...

Abstract

The invention discloses a tram steering control method and device based on path control, wherein the method includes obtaining the geometric parameters, traffic parameters and target paths to be optimized of the road sections with tram green wave design requirements; constructing and solving The optimization model aimed at maximizing the weighted sum of the green wave bandwidth of social vehicles forms independent green wave bands for trams and social vehicles by adjusting the signal cycle, phase order and phase difference; according to the model optimization results, the actual Adjust the signal control parameters of the road section. Based on the traffic flow, geometric size, vehicle travel time and phase duration and composition of the actual road section, the present invention unifies the cycle of each intersection and optimizes the phase difference, thereby providing independent green traffic for social vehicles and trams. Wave. And not only can it be used to model the traffic system including single-line trams, but also can optimize the trunk signal system of multi-line trams.

Description

technical field [0001] The invention belongs to the field of traffic safety control, and in particular relates to a path control-based tramway steering control method and device considering the green wave design of the tramway. Background technique [0002] With the rapid development of the economy, 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 method, trams can effectively carry traffic and travel, thereby reducing the operational pressure on the transportation system. However, limited by the imperfection of the green wave signal design method including trams, trams have not been widely used at present. In the application scenarios, in order to ensure that trams pass through intersections smoothly, it is often necessary to encroach on the right of way of social vehicles, thereby reduc...
