StreetDesignAI: Broadening Designer Perspectives Through Multi-Persona Evaluation of Cycling Infrastructure

Duanya Lyu, Mateo Nader, Sihan Chen, Wanghao Ye, Xiang Yan, Yilong Dai, Zijian Ding, Ziyi Wang

Structured feedback from multiple AI-simulated cyclist personas helps transportation designers identify and address conflicting user needs more effectively than general-purpose chatbots.

Claims

C1strongest claim

A within-subjects study with 26 transportation professionals comparing StreetDesignAI against a general-purpose AI chatbot demonstrates that structured multi-perspective feedback significantly broadens designers' understanding of various cyclists' perspectives, ability to identify diverse persona needs, and confidence in translating those needs into design decisions.

C2weakest assumption

That the AI-simulated cyclist personas, derived from crowdsourced assessments, accurately and reliably represent the real experiential differences across diverse user groups in actual street environments.

C3one line summary

StreetDesignAI uses multi-persona AI feedback to help designers identify and resolve experiential conflicts in cycling infrastructure through structured evaluation and iterative modification.
