A Review of Street Representation Methods for Pedestrian Surveys

This literature review explores researchers’ approaches to visually representing street environments in surveys. We examine various methods, including in-situ surveys, immersive virtual reality, real-world videos, simulated videos, photographs, and illustrations. We briefly discuss the strengths and weaknesses of each representation method. We also develop criteria for evaluating representation methods, including participant effort, information quantity, and survey development costs. We find that most researchers do not describe detailed protocols or validate the comprehensibility of survey images. Selecting the most suitable representation method for a study involves a trade-off between researchers’ goals and resources.
