Evaluation Of Guidance Sign Set Project Based On Passenger Wayfinding Behavior In Rail Transit Hubs Using Simulation Method

As the window of modern urban transport service, the spatial environment design of rail transit hubs (RTH) requires a higher standard of "humane" to meet the traffic requirement in large passenger flow, multifunction and high service level under the condition of construction increasing dramatically, spatial layout improving complicatedly and the passenger flow going up crowdedly. Especially when the so-called "native information" including spatial environment of structure and layout is fixed on, it has great significance to improve the level of passenger service in RTH in the research on the "added information" which embodied the guidance sign system. However, research on evaluation and optimization of guidance sign system was relatively little, meanwhile more research confined in the design of its content,·size, color and interference reduction. Therefore, this dissertation studies on evaluation of guidance sign set project by dynamic simulation in order to come up with effective evaluation method.Firstly, this dissertation reviewed the existing research on the wayfinding and guidance sign system, analysed the factors of the two object in detail, introduced the human visual mechanism, and draw into the parameters in vision, visual angle, visual field and visual distance. Then interaction relationship between passenger wayfinding and guidance sign was obtained, so the theoretical foundation for the research on simulation model of dynamic evaluation was laid.On the basis of the definition, process and meaning of wayfinding and its interaction of sign, chose the Beijing South Railway Station for was chosen as the research target. The characteristics and passenger wayfinding behavior were excavated by scaled survey in tracking, interview and making questionnaire. Meanwhile some parameters were calibrated. By doing these, a series model of passenger wayfinding behavior was built to provide key method for the dynamic simulation evaluation.Based on the features of the guidance sign physical property and the interaction between passengers and signs, an evaluation index system was put forward from the economy, convenience and comfort viewpoint, which was part of multi-level evaluation index system including the sign set point, line and surface.Using the wayfinding model and computer simulation technology, and combing the evaluation index system, the simulation system of evaluation guidance sign design in RTH based on passenger wayfinding behavior was developed, which contained five functional module including system setup, management, simulation operation, monitoring, statistical analysis and output.Finally, three application examples for guidance sign design evaluation of Beijing South Railway Station underground floor were introduced, which included typical passenger entry route, exit route and transfer route. What’s more, the verity and validity of this simulation system was proved by the comparative analysis of actual video data and simulation data. Then the optimized set project of guidance sign in every typical example was given. Ultimately, the quantitative and qualitative suggestions of guidance sign design in RTH were proposed by systematic summarizing and analysis.In a word, the research had demonstrated that the dynamic simulation evaluation method which based on the passenger wayfinding behavior could provide an effective means and decision-making basis for evaluation on guidance sign design. And this simulation system for the secondary development of SRail system was the useful tool to evaluate the guidance sign design.
