The invention discloses a subway station guiding identification evaluation optimization method based on VR, and the method comprises the following steps: 1), building a three-dimensional model of a subway station, implanting a simulated pedestrian track of a passenger flow in the subway station into the three-dimensional model, and building a three-dimensional virtual reality environment; 2) establishing a guiding identification system optimization model by taking maximum identification service efficiency as a target based on the probability of guiding the service by the guiding identification; 3) carrying out an immersive virtual reality pedestrian way-finding behavior test, and obtaining an identification utilization rate and point, line and plane three-level quantitative evaluation index data in the guiding identification system; (4) solving the model in the step (2) by adopting a genetic algorithm and utilizing the identification utilization rate in the step (3), and obtaining an optimal solution of a guiding identification position under the scheme; and 5) turning to the step 3), and when the point, line and surface three-level quantitative evaluation result meets the requirement, determining that the guiding identification system scheme is optimal. According to the method, the objectivity and scientificity of guiding identification evaluation are greatly improved.
Description
technical field [0001] The invention relates to traffic planning technology, in particular to a VR-based evaluation and optimization system for guide signs of subway stations. Background technique [0002] With the rapid development of the national economy and the acceleration of urbanization, the subway has become an important means of public transportation for the public. The large-scale, complex and complex functions of subway stations and surrounding spaces make it more difficult to find their way inside. Pedestrians often stop, wander, get lost, and stay, which affects the management of the station and the travel experience of passengers. , which not only consumes time and energy for passengers, but also reduces the overall efficiency of the subway station. Therefore, in large-scale crowd gathering places, the guide signs that can provide guidance services play a huge role. How to maximize the service efficiency of the guide sign system and improve the overall use effi...
