一句话总结

本文提出了一套全面且即用的行人模拟软件功能评估检查清单，旨在帮助从业者选择合适的工具，并指导开发者满足市场需求。该检查清单涵盖建模、可视化、验证和可用性等方面，配有可自动化的电子表格以评估完整性和最低要求，促进基于代理的群体模拟应用在标准化和可靠性方面的提升。

ABSTRACT

The employment of micro-simulation (agent-based) tools in the phase of design of public and private spaces and facilities and for the definition of transport schemes that impact on pedestrian flows, thanks to their achieved accuracy and predictive capacity, has become a consolidated practice. These instruments provide support to the organization of spaces, services and facilities and to the definition of management procedures for normal and emergency situations. The employment of these tools is effective for various but not for all the contexts, nevertheless new features and functions are under constant development and new products are often launched on the market. Therefore, there is a higher necessity of a standard criteria both for the evaluation of the kinds of function that these software provide, at use of practitioners and end-users, and for the definition of software requirements as a reference for the developers that aim at being competitive on this market. On the basis of our experience as pedestrian modellers and as researchers in the crowd modelling area, we designed a comprehensive and detailed ready-to-use checklist for the quantitative evaluation of Pedestrian Simulation Software functionalities that aims at capturing all the aspects that we claim that are useful to undertake a professional study. These functions in our opinion are necessary to provide accurate results in the planning of new facilities or schemes that involve pedestrian activities. With this work we propose a set of criteria of evaluation for these products also to encourage a debate for the definition of objective standards for pedestrian simulation software certification.

研究动机与目标

• 解决专业和学术使用中行人模拟软件缺乏标准化评估标准的问题。
• 为从业者提供一种实用工具，依据功能完整性选择模拟平台。
• 指导软件开发者将其产品与市场需求和模拟最佳实践对齐。
• 推动行人模拟软件客观认证标准的发展。
• 支持在交通枢纽、体育场和应急场景等复杂环境中开展稳健、准确且可复现的模拟研究。

提出的方法

• 检查清单分为10个类别，包括2D/3D环境建模、代理行为、路径规划、可视化和验证等。
• 每个类别包含具体的功能项目，通过可自定义的自动化电子表格以“是”、“否”或“开发中”进行评分。
• 评估包含两种反馈机制：最低要求满足情况和整体完整性百分比。
• 检查清单基于从业者在群体动力学和模拟最佳实践方面的经验制定，并参考了既有的标准（如Fruin的交通服务水平，Level of Service）。
• 验证标准包括与真实数据对比、符合公认标准（如《公路通行能力手册》）以及第三方认证。
• 评估电子表格的测试版本已公开发布，供反馈和实际应用。

实验结果
